THE PUBLIC UTILITIES COMMISSION has requested an advisory opinion,
pursuant to Public Utilities Code section 854, on the following questions:
1.
Will the proposed merger between Pacific Enterprises and Enova Corporation
adversely affect competition?
2.
What mitigation measures could be adopted to avoid any adverse effects on
competition that do result?
1.
The proposed acquisition between Pacific Enterprises and Enova Corporation
should not by itself adversely affect competition in the markets for interstate gas or
wholesale electricity.
2.
The merger may eliminate the disciplining effect of San Diego Gas & Electric
as a potential competitor in the partially regulated intrastate gas transmission market. We
recommend that the Commission consider requiring the merged entity to auction offsetting
volumes of transportation rights within that system.
The proposed merger of Pacific Enterprises and Enova Corporation is a response
to the mandatory restructuring of the electric industry which began on January 1, 1998.
Through their subsidiaries, Pacific is the leading southern California supplier of intrastate
gas transmission services, Enova is an electric distributor and a relatively minor participant
in the wholesale electricity market, and both firms distribute gas within their respective
service areas. As regulated utilities doing substantial business within this state, the parties
have submitted their application under Public Utility Code section 854. This memorandum
responds to a Commission request for an opinion on the competitive effects of the
transaction.
Challenges to the merger have primarily focused upon alleged effects in the markets
for wholesale electricity, interstate gas and intrastate gas transmission. Through Southern
California Gas Company (SoCalGas), Pacific provides gas transmission services to many
of the gas-fired generation plants within southern California, including plants now owned
by San Diego Gas and Electric (SDG&E) and Southern California Edison (Edison).
Edison and others contend that the merged company will "leverage" its position in the gas
transmission market to manipulate the price of electricity sold by these plants in the
wholesale market. Intervenors also allege that the applicants will unfairly benefit in
financial markets and that, by exercising options to purchase competing intrastate facilities,
their alleged ability to manipulate electricity prices will be enhanced in the future.
We conclude that this merger will not adversely affect competition within either the
wholesale electricity or interstate gas markets. Because gas-fired plants now owned by
SDG&E will be subject to comprehensive price regulation, the merged entity will lack any
incentive (or, usually, the ability) to manipulate wholesale electricity prices. Moreover,
the wholesale electricity and interstate gas markets are already highly integrated, and
comprise most of the western United States. Price data -- as opposed to theoretical models
-- shows that the wholesale electricity market connects California with numerous out-of-state suppliers over a transmission system that has never reached capacity. These out-of-state suppliers, along with California generation plants outside the SoCalGas service area,
would defeat any attempt by the merged entity to raise wholesale electricity prices above
competitive levels. In any event, SoCalGas cannot significantly increase the costs of
southern California gas-fired plants, whose gas prices are determined in the competitive
interstate market and most of whose intrastate transportation rates are at their regulatory
caps.
We also conclude that the merger of the utilities' procurement operations will not
adversely affect competition in the interstate gas market and that the applicants are not
actual potential competitors for retail electricity services. On the other hand, because the
merger may eliminate the disciplining effect of SDG&E as a potential competitor in the
partially regulated intrastate gas transmission market, we recommend that the Commission
consider requiring SoCalGas to auction offsetting volumes of transportation rights within
that system. Finally, because of the uncertain effects of electric industry restructuring, we
also recommend that the Commission retain limited jurisdiction over this merger for the
purpose of reexamining the question of whether the merged entity has used its intrastate
gas transmission system for the purpose of manipulating the price of electricity it sells in
the wholesale market.
I.
PRIOR PROCEEDINGS AND THE NATURE OF THIS OPINION
This merger would be completed by combining Enova and Pacific into NewCo, a
holding company created for the purpose of consummating this transaction. Footnote No. 1 NewCo
Enova Sub would merge into Enova, with Enova as the surviving corporation. Likewise,
NewCo Pacific Sub would merge into Pacific with Pacific as the surviving corporation.
Enova and Pacific would be wholly-owned NewCo subsidiaries. Enova, Pacific, SDG&E,
and SoCalGas would operate separately and under their existing names.
On June 25, 1997, the Federal Energy Regulatory Commission (FERC)
conditionally approved the merger. Footnote No. 2 In general, the conditions imposed by FERC would
require SoCalGas to treat SDG&E and other affiliates "in the same way pipelines treat
their gas marketing affiliates." Footnote No. 3 The applicants subsequently incorporated those conditions,
along with other proposed restrictions, within their merger application. Footnote No. 4
This is the fifth opinion letter submitted by this office under the 1989 amendments
to Section 854. Footnote No. 5 Public Utility Code section 854 refers to the opinion as advisory. Footnote No. 6
Consequently this document does not control the PUC's finding under section 854,
subdivision (b)(3). However, the Attorney General's advice is entitled to the weight
commonly accorded an Attorney General's opinion (see, e.g., Moore v. Panish (1982) 32
Cal.3d 535, 544 ("Attorney General opinions are generally accorded great weight");
Farron v. City and County of San Francisco, (1989) 216 Cal.App.3d 1071).
II.
THE APPLICANTS AND THE INTRASTATE GAS TRANSPORTATION AND
ELECTRICITY SERVICES THEY PROVIDE
Pacific Enterprises and Enova Corporation currently compete on a very limited
basis. SoCalGas purchases gas in the interstate market, which it distributes to its 4.7
million residential and other "core" customers in southern and central California. "Core"
customers include residential and commercial customers without alternate fuel capability,
whereas "non-core" customers are large commercial and industrial consumers that can buy
gas from different sources. SoCalGas is the leading supplier of intrastate gas transmission
and gas storage services for both "core" and "noncore" customers within southern
California. Pacific Enterprises also sold electricity in the wholesale market through QF
facilities, all of which were recently divested. Footnote No. 7 In 1996, Pacific generated revenues of
$1,613 million from its gas distribution operations and $778 million from intrastate gas
transportation services provided to commercial/industrial and gas-fired generation plants.
SDG&E, which actively buys and sells power in the wholesale market, Footnote No. 8 sells
electricity to 1.2 million retail customers in San Diego and southern Orange Counties
(including parts of the SoCalGas service area). SDG&E also purchases gas in the
interstate market, Footnote No. 9 which it distributes within its separate service areas. Footnote No. 10 SDG&E provides
no gas transmission services outside of San Diego County. Footnote No. 11 In addition, an affiliate of
Enova Corporation, Enova Energy, conducts extensive wholesale and retail energy
marketing activities throughout California. In 1996, Enova generated revenues of $1,591
and $348 million from its electricity and gas distribution operations, respectively.
Applicants have formed a joint venture, Energy Pacific, to market gas, power and
a "broad range of value-added energy management products and services." Footnote No. 12 The
applicants also recently purchased AIG Trading, a natural gas and electricity marketer and
a trader in financial markets for electricity and gas contracts. Footnote No. 13 Both of those companies
are actively involved in the electricity and gas markets in California. This section
discusses intrastate gas transmission services supplied by SoCalGas and SDG&E purchases
and sales in the restructured electric industry. Interstate gas and electric services are
discussed in Section III.
The applicants claim that their merger will produce a firm with the necessary
breadth and financial strength to compete with Edison, PG&E and out-of-state suppliers
in the restructured electric industry mandated by AB 1890. As a result of that
restructuring program, SDG&E and other California electric utilities will lose their
exclusive "franchises" on January 1, 1998. The applicants contend that the merger will
provide Enova, which is approximately one-fifth the size of Edison and PG&E, Footnote No. 14 with
"access to adequate quantities of capital on favorable terms." The parties also believe that
the merged company will achieve certain efficiencies and will respond more effectively to
customer demand for broader and more cost effective energy services.
B.
SDG&E Market Power Mitigation under Electric Restructuring
Under industry restructuring, two separate central authorities, the Power Exchange
(PX) and the Independent Service Operator (ISO), will coordinate all transactions between
SDG&E and other California utilities. Footnote No. 15 SDG&E currently purchases a majority of the
electricity it sells to its retail customers. In 1995, for example, SDG&E obtained 61
percent of its power requirements from short-term Western States Coordinating Council
(WSCC) purchases, 22 percent from fossil generation plants--including its own 1,973 MW
capacity plants--located within the San Diego Basin, Footnote No. 16 and the remaining 17 percent from
the San Onofre Nuclear Generating Station (SONGS). Footnote No. 17 In 1996, the peak load for the
SDG&E system was 3,299 MW. Footnote No. 18
During a five year transition period beginning January 1, 1998, SDG&E and other
investor owned utilities (IOUs) must purchase and sell all of their power through the PX,
which will establish a single clearing price for all hourly transactions. Footnote No. 19 Participating
distribution companies and end users will submit "demand side" bids to the PX. Footnote No. 20
Generation plants and marketers will simultaneously submit advance supply bids. Footnote No. 21 The
total capacity of WSCC members, including capacity divested from Edison and PG&E, Footnote No. 22
which can bid into the PX exceeds 150,000 MW. Footnote No. 23 From the resulting demand and supply
schedules, the PX will establish Footnote No. 24 the market "clearing price" governing all purchases and
included sales. Footnote No. 25
Power produced by "must-take" and "must-run" resources will be priced separately.
The output of must-run units -- the fossil generating plants used by the ISO to maintain
system integrity Footnote No. 26 -- will be sold at their variable operating costs. Footnote No. 27 The ISO Governing
Board "has chosen all of SDG&E's units for Must-Run status." Footnote No. 28 Must-take resources,
which include SONGS and other nuclear plants, qualifying facilities (QFs) and pre-existing
power contracts, Footnote No. 29 provide more than half of the electricity requirements of the California
IOUs. Footnote No. 30 A "performance incentive mechanism . . . will isolate SONGS revenue received
by SDG&E from the PX price." Footnote No. 31 Other nuclear power output prices will be regulated by
the PUC, and existing contracts will determine the price of purchased power and QF
output.
To preclude the exercise of any possible market power, SDG&E will bid the output
of its gas-fired and other plants into the PX under ISO "Agreement B" Footnote No. 32 during periods
when those plants are not operated on a must-run basis. That agreement applies separate
payment provisions to the two periods. As noted above, SDG&E will recover its variable
costs during must-run periods. At other times, Agreement B requires the operator to
return to the ISO "90 percent of any revenues earned in excess of the running costs." Footnote No. 33
The remaining ten percent will apparently be applied to SDG&E stranded costs through
the competitive transition charge (CTC) mechanism. Footnote No. 34 On October 30, 1997, FERC
concluded that this arrangement "adequately mitigate[s] [SDG&E's] generation market
power for PX sales of energy." Footnote No. 35
In conjunction with the PX, the ISO will coordinate intrastate power flows and
provide open access to the California transmission grid. Footnote No. 36 On January 1, 1998, all
participants will transfer operational control of their transmission facilities to the ISO. Footnote No. 37
The state will initially be divided into "congestion zones" for northern and southern
California, within each of which little or no congestion is expected. Users within the
zones will pay a single transmission access charge based upon the revenue requirements
of the owners of the transmission facilities. Footnote No. 38 A bidding process, similar to that used by
the PX, will establish usage charges for entities which transmit power over congested paths
through or out of the ISO grid. Footnote No. 39
C.
SoCalGas Intrastate Gas Transmission Services
SoCalGas carries gas to its "core" and "noncore" customers from delivery points
for interstate pipelines or their intrastate extensions. When it created these customer
classifications in 1986, the PUC required SoCalGas to offer "transportation only" services
to its noncore customers, including generation plants owned by some of the intervenors in
this proceeding. Since 1986, the ability of noncore customers to choose among gas
producers and transportation services has been significantly expanded.
1.
The SoCalGas Intrastate System
Five interstate pipelines carry natural gas to California: the Transwestern Pipeline
Company ("Transwestern"); the El Paso Natural Gas Company ("El Paso"); the Pacific
Gas Transmission Company ("PGT"), a PG&E subsidiary; the Kern River Transmission
Company ("Kern River"); and the Mojave Pipeline Company ("Mojave"). At the Arizona-California border, SoCalGas receives gas from the Transwestern line at North Needles and
from the El Paso line at Topock and Blythe. Footnote No. 40 In the northern part of its service area,
SoCalGas receives gas from PG&E at Kern River Station and Pisgah, Footnote No. 41 and from the Kern
River and Mojave lines at Wheeler Ridge and Hector Road. Footnote No. 42 The SoCalGas system is
capable of receiving approximately 3.5 Bcf/d at these connection points. Footnote No. 43
The SoCalGas Acquisition Group purchases about 1000 MMcf/d, which is
ultimately transported to core customers. Footnote No. 44 SoCalGas noncore transportation customers
include Edison, members of SCUPP, SDG&E, the City of Long Beach, and various large
commercial and industrial customers. Footnote No. 45 SoCalGas supplies 42 gas-fired generation plants,
including plants owned by SDG&E, Edison, Imperial Irrigation District (IID) and SCUPP
members. Footnote No. 46 These plants have a total generating capacity of 15,837 MW. Footnote No. 47 SoCalGas is
the only intrastate gas pipeline to which SCUPP members can feasibly connect. Footnote No. 48
To coordinate deliveries to these customers and to preserve "system integrity," Footnote No. 49
SoCalGas calculates in advance of "flow day" Footnote No. 50 a system "window" from the difference
between estimated overall next-day demand Footnote No. 51 and local Footnote No. 52 California gas production. Footnote No. 53 This
"take away" capacity figure is then adjusted by anticipated injection or withdrawal
volumes Footnote No. 54 for SoCalGas storage fields, Footnote No. 55 which according to Edison "are used to satisfy the
majority -- approximately 57% -- of peak day demand." Footnote No. 56 Windows are also established
at each of the individual receipt points. Footnote No. 57 SoCalGas uses a variety of procedures, including
"custody cut" Footnote No. 58 and Rule No. 30 restrictions, Footnote No. 59 to achieve system balance when demand
"nominations" for core and noncore customers exceed system or individual receipt point
windows. Footnote No. 60
2.
Transportation "Unbundling" and System Bypass
When the PUC "unbundled" transportation services in 1986, noncore customers
were able to directly purchase commodity from wellhead producers at competitive prices
and to make their own arrangements for the transport of that gas over interstate pipelines.
In subsequent years, the Commission has also permitted the creation of a limited secondary
market for intrastate transportation, even though it still prohibits "brokering on the
intrastate system." Footnote No. 61 The GasSelect electronic bulletin board, "an interactive same-time Footnote No. 62
reservation and information system," Footnote No. 63 provides information within this secondary market
about intrastate transportation transactions between SoCalGas and its affiliates. Footnote No. 64
Bypass opportunities for noncore customers have also been expanded. The Kern
River and Mojave pipelines responded to these opportunities by extending their interstate
systems across the California border into the SoCalGas service territory. Footnote No. 65 SoCalGas
withdrew its initial opposition under 1989 agreements providing it with options to purchase
in the year 2012 the California extensions of those two lines. Footnote No. 66 Since their completion in
1992, both systems have delivered gas to Enhanced Oil Recovery (EOR) and related
cogeneration loads, and "to SoCalGas and PG&E for redelivery to other industrial and
commercial loads." Footnote No. 67
This competition has induced SoCalGas to "provide discounted Footnote No. 68 transportation rates
and associated cost saving to numerous customers [perhaps including SDG&E Footnote No. 69] on its
system." Footnote No. 70 SoCalGas can provide such discounted service to noncore customers without
obtaining prior CPUC approval. SoCalGas estimates that, since 1992, it has lost
transportation volumes of 400 million cubic feet per day to competing gas pipelines. Footnote No. 71
SoCalGas also claims that competition from out-of-state electric generation plants ("bypass
by wire") has reduced the aggregate load of California gas-fired facilities by an additional
275 million cubic feet per day. Footnote No. 72
Along with federal deregulation efforts, these changes left SoCalGas and other
utilities with contracts for interstate pipeline capacity that exceeded their market
requirements. Accordingly, SoCalGas has since 1992 reduced its firm capacity on the El
Paso pipeline from 1750 MMcf/d to 1150 MMcf/d and from 750 MMcf/d to 300 MMcf/d
on the Transwestern system. Footnote No. 73 To mitigate the resulting losses, the PUC has required
customers to pay SoCalGas an ITCS (Interstate Transportation Cost Surcharge) Footnote No. 74 to help
recover certain fixed capacity costs. Footnote No. 75
III.
INTERSTATE GAS AND WHOLESALE ELECTRICITY MARKETS AT THE
CALIFORNIA BORDER
SoCalGas and California generation plants purchase the majority of their gas
supplies from four producing basins in the western United States and Canada. Footnote No. 76 Likewise,
SDG&E purchases the majority of its electricity supplies from western United States and
Canadian generation plants.
As a result of federal deregulatory efforts, these western United States gas and
electricity markets are fully competitive. Both industries consist of three vertically-related
stages: production, transmission, and distribution. Footnote No. 77 Production and interstate transmission
services within both of those markets are highly integrated at the California border.
Moreover, California wholesale electricity transactions, which SDG&E and other utilities
now make throughout the western United States, will remain integrated with the interstate
market after the January 1, 1998 restructuring.
A.
Federal Deregulation and the Interstate Gas Market
Federal deregulation of the gas market has created a network of transmission
suppliers connecting purchasers at the wholesale level with middlemen and well operators
at the production level. Prior to these efforts, each interstate "pipeline would purchase
natural gas from producers, transport it largely along their own proprietary pipeline
system, and resell the rebundled product to local distribution companies (LDCs) and other
large customers." This institutional structure meant that "each producer could sell gas to
a limited number of buyers" and that "LDCs and large end users had limited options in
terms of the number of pipeline companies from which they could purchase gas." Footnote No. 78 As a
result of FERC's deregulatory policies, "an active and viable spot market has developed
for gas." Footnote No. 79
FERC transformed the gas industry by providing open access to interstate pipelines,
removing all controls over the wellhead price of natural gas, Footnote No. 80 and establishing secondary
markets for storage and pipeline capacity. Footnote No. 81 Pipelines now compete to provide
transportation services with each other and with middlemen and with other owners of
capacity rights. Wellhead deregulation has simultaneously generated competition between
producers in different basins. Footnote No. 82 Because end users attempt to minimize their "delivered
prices," Footnote No. 83 competitive forces have also linked the production and transmission markets.
FERC's open access policies, instituted in Orders 436 Footnote No. 84 and 636, required that
interstate pipelines separate gas sales from transportation services, Footnote No. 85 allowing users to enter
into direct agreements with producers at the wellhead and arrange transportation in a
separate transaction. Orders 436 and 636 also created a "secondary transportation market"
for natural gas Footnote No. 86 by allowing "holders of unutilized firm capacity [to resell] them in
competition with any capacity offered directly by the pipeline." Footnote No. 87 Previously, shippers
were only able to purchase capacity rights directly from pipelines. Footnote No. 88 Under Order 636,
shippers who wish to sell (i.e. "release") their firm capacity rights must first offer Footnote No. 89 those
rights on the pipeline's electronic bulletin boards ("EBB") Footnote No. 90, which carry "information
about available and consummated capacity release transactions." Footnote No. 91
These policies have allowed producers in Canada, the Rocky Mountains, the San
Juan and Permian Basins, as well as other regions to compete for sales throughout
California. The five pipelines which deliver this gas have an aggregate capacity of 7,130
MMcf per day. Footnote No. 92 The 3.5 Bcf/d El Paso Natural Gas Company and the 1.1 Bcf/d
Transwestern Pipeline Company lines are the primary links between the southern
California border and producers in the San Juan and Permian basins. Footnote No. 93 Pacific Gas
Transmission Company ("PGT"), a PG&E subsidiary, transports gas from Canada to the
California border on its own 1.89 Bcf/d pipeline. Coupled with downstream pipeline
system operated by SoCalGas and SDG&E, PG&E can serve end users in most of
California. Footnote No. 94 As noted in Section II, the 770 MMcf/d Kern River line, which originates
in the Rocky Mountain Basin, and the 400 MMcf/d Mojave pipelines began commercial
operations in 1992.
In this deregulated interstate market, both purchasers and suppliers have various
alternatives as they seek to minimize the overall cost of purchasing, transporting and
storing gas. Footnote No. 95 Thus, many EOR customers, who previously transported gas from
Southwest fields over the El Paso or Transwestern lines, substituted when they found it
more economical to transport Rocky Mountain gas over the Kern River or Mojave lines. Footnote No. 96
In other instances, customers have substituted by transporting over the same pipeline to
California gas purchased in entirely different basins. Footnote No. 97 Customers committed to a
particular supply source can also substitute between firm contracts and capacity released
in the secondary market. Footnote No. 98 Commodity and transportation markets are also linked, Footnote No. 99 as
producers in the San Juan Basin demonstrated between November 1990 and April 1992 and
again between March 1995 and December 1996 by reducing commodity prices to offset
the temporarily increased cost of transporting gas over the constrained El Paso line. Footnote No. 100
B.
Federal Wholesale Electricity Deregulation
Federal deregulation has had similar effects on wholesale electricity prices at
California delivery points. Congress initiated deregulation of the electricity industry by
first allowing independent power producers and then utility affiliates to offer wholesale
electricity at "market-based prices." Footnote No. 101 Through Order 888 and earlier mandates, Footnote No. 102 FERC
simultaneously encouraged open access and other "wheeling" transactions between non-contiguous buyers and sellers. Footnote No. 103 By 1993, the "wholesale sector of the U.S. electricity
industry [had] been transformed from an industry dominated by ineffectively regulated,
inefficient monopolists to an industry that is increasingly dominated by robust
competition." Footnote No. 104
Edison, SDG&E and PG&E actively participate in one of the most integrated of
these wholesale electricity markets, the WSCC, which includes "fifteen states in the
western United States and part of Canada." Footnote No. 105 The WSCC "is a highly complex network
that interconnects the entire western United States from Canada to Mexico and east as far
as Montana, Utah, and New Mexico." Footnote No. 106 WSCC members include Bonneville Power &
Light, British Columbia Hydro, Los Angeles DWP, SMUD, and the Salt River Project.
The aggregate capacity of WSCC members, which arrange wholesale electricity
transactions through the Western States Power Pool ("WSPP") or through separate bilateral
transactions, Footnote No. 107 exceeds 150,000 MW. Footnote No. 108
As a result of industry deregulation, suppliers can now sell to any purchaser on the
grid. Footnote No. 109 In fact, the availability of displacement contracts and the physics of electricity
transmission has rendered irrelevant transmission constraints between any two points
within the network. Footnote No. 110 The existence of "loop flows," Footnote No. 111 in particular, means that power
in a network "moves across many parallel lines in often circuitous routes." Footnote No. 112 Likewise,
suppliers facing transmission constraints can indirectly meet their contractual obligations
by entering into offsetting displacement contracts with sellers located on unconstrained
links to the delivery point. Footnote No. 113 Accordingly, sellers must now compete for any sale with
utility affiliates, independent power producers and power marketers.
The resulting competition has dramatically increased the integration and efficiency
of the wholesale electricity market. The WSCC, in particular, had actually become a
highly integrated market even before FERC issued Order 888. Footnote No. 114 Using data from 1994-1996 transactions, De Vany and Walls have shown that the implicit delivered price of
wholesale electricity is identical throughout the western United States during most hours
of the day. Footnote No. 115 The market is so highly integrated, in fact, that arbitrage opportunities are
virtually nonexistent between supply points during both "peak" and "off-peak" hours.
Thus, De Vany and Walls found that the California-Oregon Border ("COB"), Northern
California, Palo Verde and Southern California were cointegrated Footnote No. 116 with all ten of the
other major WSCC delivery points examined during off-peak hours; and with 9, 9, 10, and
9 of the other 10 delivery points, respectively, during peak hours. Order 888 has
undoubtedly strengthened these results. Footnote No. 117
C.
The PX and the Western United States Wholesale Market
ISO and PX rules will allow out-of-state utilities to bid into the PX. Footnote No. 118 Those out-of-state suppliers will compete for sales of wholesale electricity sold through the Power
Exchange, and their participation will equalize prices between the Exchange and the larger
market. Any differences between the Power Exchange price and the prevailing wholesale
price would also be disciplined by marketers and California utility customers who would
bypass the PX and arrange direct purchases from out-of-state sources. Footnote No. 119
As noted above, loop flows maintain system viability when constraints arise over
individual transmission paths. The "contract path" between a generating plant and a
customer is a "fiction," which "may and often does diverge" from the actual flow of
power. Footnote No. 120 Thus, the physics of electrical networks would allow southern California
customers to withdraw from the WSCC transmission grid power simultaneously generated
by BPA, even if a link in the most direct transmission route between the two parties (e.g.,
Path 15) were at capacity. For that reason, the precise capacity of any single link between
California and other WSCC members is not relevant to this proceeding. Footnote No. 121
Price data -- which provides the best measure of market performance -- confirms
the implications of engineering data which show that California has never been isolated
from the rest of the WSCC. Footnote No. 122 During off-peak hours, the implicit "shadow" price for
transmitting electricity between the four major California delivery points at off-peak hours
is virtually zero, Footnote No. 123 reflecting the system's low variable supply costs. Implicit peak hour
transmission rates are higher, but wholesale electricity prices at the four delivery points
during those times remain cointegrated within arbitrage bounds. Footnote No. 124 These data are
inconsistent with the fragmented transmission system and isolated wholesale markets
alleged by some intervenors.
IV.
THE RELEVANT MARKETS
The traditional antitrust model assesses the competitive effects of a merger within
a "relevant market," which generally exhibits both product and geographic dimensions.
The relevant product refers to the "horizontal" range of products or services that are or
could be easily be made relatively interchangeable, so that pricing decisions by one firm
are influenced by the range of alternative supplies available to the purchaser. The
substitutes comprising the product market can be differentiated, at least to some extent.
Thus, local telephone calls within the same exchange between A and B and between C and
D are not identical services, but they are still in the same product market because they are
such close substitutes.
The relevant product also has a vertical dimension. In most antitrust cases, there
is a "range of possible markets of varying breadth." Footnote No. 125 In theory, the horizontal and
vertical dimensions of the relevant market are "immaterial." Footnote No. 126 In fact, however, empirical
limitations require a "noticeable 'gap in the chain'" of substitutes and complements. Footnote No. 127 For
example, it would usually be misleading to define separate product markets for left and
right shoes or, because they are so strongly linked, for ski boots and ski bindings. Footnote No. 128 More
generally, the relevant product is defined by including the good which is immediately in
question along with all other substitutes and complements which significantly affect the
ability of the supplier to raise price above marginal cost.
Similar considerations govern the delineation of the relevant geographic market.
The relevant geographic market is defined as the area in which sellers compete and in
which buyers can practicably turn for supply. Footnote No. 129 In any market, including interstate gas
or wholesale electricity networks, the relevant geographic market will include all supplies
whose prices remain closely linked, after transportation and other transaction costs are
accounted for. Thus, distant seller A and local seller B are in the same market if the price
at B equals the price at A plus the cost of transportation between the two points. More
generally, two locations are in the same market if the differential between their (possibly
independently varying) prices remains "less than the potential wedge created by arbitrage
costs." Footnote No. 130 Accordingly, "[p]rice relationships are clearly the best single guide to
geographic market definition." Footnote No. 131
A.
The Relevant Interstate Gas Market
For purposes of analyzing this merger, a relevant market can be defined as gas
delivered at interstate receipt points by pipelines from the San Juan Basin, the Permian
Basin, and basins in the Rocky Mountains and Canada. Footnote No. 132 In a gas network, the ability of
a customer (like SoCalGas) to deviate rates from competitive levels is determined by
conditions at the wellhead, within the network itself, and at the ultimate delivery points.
As noted above, users base their purchasing decision upon the overall delivered cost of the
commodity, not the price at a particular wellhead or the cost of transmission over a single
line. Prices are inextricably linked between basins, between pipelines, between firm and
interruptible capacity on each line, Footnote No. 133 and across these various service levels. Footnote No. 134 The most
limited product market providing a "gap" in this "chain" of complements is delivered
interstate gas.
The geographical extent of this market includes at least deliveries from the four
basin area. Footnote No. 135 In 1995, total average production by these basins was 24,000 MMcf/d. Footnote No. 136
Estimated peak day supplies to California are 3,536 MMcf/d. Footnote No. 137 Because gas deliveries
throughout the network are close substitutes, after transportation is accounted for, the
geographic market is broader than gas deliveries to southern California customers. Footnote No. 138
Similarly, the relevant product and geographic market is broader than capacity rights on
the El Paso line between the San Juan basin and the California border. Footnote No. 139
Competition within this market is intense. The ability of a firm to raise prices
above competitive levels is "commonly" shown with circumstantial evidence of industry
concentration, Footnote No. 140 entry barriers, and the short-run ability of existing competitors to increase
their output. Footnote No. 141 The courts also recognize the use of "direct evidence" to resolve market
power questions. Footnote No. 142 In the relevant interstate gas market, there are many buyers and sellers
at the wellhead level, numerous holders of capacity rights competing with pipeline owners
for transportation services, and strong price interactions between those levels. Moreover,
"direct" evidence shows that prices at delivery points within the four basin area remain
cointegrated within arbitrage bounds.
B.
The Relevant Wholesale Electricity Market
A relevant market also exists for wholesale electricity delivered throughout the
WSCC. Like their counterparts in the natural gas industry, customers purchase wholesale
electricity as the "delivered" combination of generation and transmission services. Footnote No. 143 Thus,
the relevant market includes all suppliers whose combined "netback" and transportation
costs would be competitive at California delivery points. Footnote No. 144 The relevant geographic
market is the WSCC because that is "the region from which generators will be able to bid
power into the Power Exchange." Footnote No. 145
The relevant product market includes "all" effectively unregulated delivered
electricity which can compete in the Power Exchange for residual wholesale electricity
demand. Footnote No. 146 Within the WSCC, the total capacity of competitive gas-fired, hydro, and coal
plants exceeds 150,000 MW. These resources will compete for the demand remaining in
the PX after sales of price-regulated must-run and must-take capacity are completed. As
in the gas industry, there are numerous buyers and sellers in the wholesale electricity
market, strong interactions between generation and transmission prices, and highly
cointegrated prices at delivery points.
1.
Alleged "Swing Capacity" Markets
The relevant product market for wholesale electricity cannot be meaningfully limited
to "swing capacity" producers. Edison and other intervenors implicitly allege a product
market consisting of generation with "full load marginal costs" Footnote No. 147 within some range Footnote No. 148 of
the variable costs of producing electricity on Edison and other WSCC gas-fired plants.
Intervenors contend that gas-fired plants with their relatively high production costs will be
the only firms bidding at or near the "clearing prices" established by the Power Exchange.
This proposed market, however, excludes Bonneville Power and other "inframarginal"
suppliers located throughout the WSCC Footnote No. 149 that are equally likely to establish the clearing
price. Footnote No. 150
Intervenors exclude these other generation sources by implicitly assuming that out-of-state participants do not incur opportunity costs. Footnote No. 151 Theoretically, PX participants will
offer wholesale electricity at their marginal supply costs, including fuel and other variable
production expenses. Footnote No. 152 In addition, however, the relevant economic cost to out-of-state
sellers Footnote No. 153 will include returns foregone by selling to the Power Exchange instead of other
western United States buyers. Footnote No. 154 The existence of these opportunity costs explains why
gas is not "the" marginal fuel, Footnote No. 155 why out-of-state suppliers will equalize the PX and
prevailing WSCC prices Footnote No. 156 and, at least in part, why gas and electricity prices are weakly
correlated in southern California. Footnote No. 157 Their existence also means that the relevant product
market includes the output of "inframarginal," out-of-state suppliers. Footnote No. 158
Similarly, the relevant market is not time-sensitive. A relevant market includes all
firms which would respond to a hypothetical "small but significant and nontransitory" price
increase. Footnote No. 159 These firms include plants which are already "committed" to the market, but
which make no contemporaneous sales. Accordingly, the relevant wholesale electricity
market during peak periods includes all out-of-state WSCC suppliers.
As discussed above, WSCC suppliers can sell electricity throughout the grid during
both peak and off-peak hours. Footnote No. 160 Some intervenors have suggested that the relevant market
will be limited during peak hours. Footnote No. 161 It is true that during those periods, supply costs
increase as some firms begin to reach capacity and (in some cases) as individual
transmission paths become congested. These transitory, geographically dispersed costs
increase price volatility. Even so, there is no evidence that, during peak periods, any
WSCC firms withdraw from the market or that any out-of-state suppliers will be
systematically excluded from the PX. In fact, price data shows that even before FERC
issued Order 888 the major California delivery points were highly cointegrated during peak
periods with the rest of the WSCC.
C.
The Relevant Intrastate Gas Transportation Market
Although the applicants and many intervenors combine it with the interstate gas
market, a separate relevant market can be defined for intrastate gas transportation and
storage services within southern California. Ten years ago, SoCalGas and PG&E were
the principal suppliers of these services. Since the completion of their intrastate extensions
in 1992, Kern River and Mojave pipelines have also competed for transportation services
to EOR and related cogeneration loads. Private pipelines provide additional competition.
Despite this recent competition, SoCalGas has maintained significant market power
over these services. SoCalGas controls most of the intrastate capacity within southern
California, including all transportation facilities located within Los Angeles, Orange and
Riverside Counties. Footnote No. 162 Moreover, as the extended Kern River and Mojave pipeline
application process demonstrated, potential suppliers face substantial regulatory entry
barriers. A controlling market position reinforced by high regulatory barriers to entry is
strong evidence of market power. Footnote No. 163 SoCalGas also price discriminates between
transportation customers, and can sometimes discount without Commission approval. Footnote No. 164
The ability to persistently price discriminate between similarly situated customers also
implies that a seller possesses market power. Footnote No. 165
Mergers are generally categorized as "horizontal," "vertical," or "conglomerate."
The competitive effects of a merger are assessed by first defining the relevant markets and
then determining whether the merged entity will have an enhanced ability to profitably
skew price or output from competitive levels. Footnote No. 166 Under the DOJ/FTC Guidelines, the
effects of a "horizontal" merger depend upon several related factors, including changes in
concentration levels, entry conditions, and efficiency enhancements. The government's
vertical merger guidelines "recognize only three possible anticompetitive effects: that
vertical mergers might create entry barriers, facilitate horizontal coordination, or allow a
regulated firm to evade rate regulation." Footnote No. 167 A failure to properly define the relevant
markets is fatal to a plaintiff's prima facie case. Footnote No. 168 A plaintiff must also demonstrate
"probabilities"--not "ephemeral possibilities"--of anticompetitive effects within those
markets. Footnote No. 169
A.
The Vertical Integration of SoCalGas Intrastate Gas Transmission and SDG&E
Wholesale Electricity Operations
Although this merger has some horizontal features, the primary link between the
applicants is the gas transportation services SoCalGas provides to SDG&E. Those
transportation services are an important component in the cost of generating electricity to
SDG&E and other gas-fired plants in southern California. Vertical integrations do not,
however, "automatically have an anticompetitive effect." Footnote No. 170 This is because, unlike
horizontal consolidations, vertical mergers do not eliminate competitors from the market. Footnote No. 171
The vertical integration resulting from this merger, in particular, will not adversely affect
competition in the wholesale electricity market because Agreement B negates any incentive
of SDG&E (or the merged entity) to manipulate PX prices.
Even without the restrictions of Agreement B, however, SoCalGas could not
significantly increase the costs of SDG&E's southern California competitors, whose gas
prices are determined in the competitive interstate market and most of whose intrastate
transportation rates are already at their regulatory caps. (Their current transportation rates
are binding because the Commission prohibits SoCalGas from raising intrastate rates above
existing tariff levels, which SoCalGas has discounted for only a small minority of the
plants it serves. Footnote No. 171.1) Moreover, out-of-state suppliers would defeat any attempt by the
merged entity to manipulate the price of wholesale electricity sold in southern California. Footnote No. 172
The total capacity of plants supplied by SoCalGas is 15,837 MW. These plants will
compete for end-users who can purchase electricity through the PX or through "direct
access" agreements, with aggregate WSCC, out-of-state capacity exceeding 100,000
MW. Footnote No. 173 Because out-of-state suppliers account for their opportunity costs Footnote No. 174 and because of the absence of entry barriers faced by out-of-state suppliers wishing to make such sales, the resulting PX price will equal the prevailing WSCC spot price. Footnote No. 174.1 Price data -- as
opposed to simulation models -- demonstrate that WSCC prices are competitively
determined. Footnote No. 174.2 Neither SoCalGas nor the merged entity will have the ability to profitably
deviate prices from competitive levels within that market.
1.
The Intervenors' Vertical Integration Models
Intervenors have failed to demonstrate with "probabilities" that the integration of
these vertically-related operations will have adverse competitive effects in any relevant
market. Relying upon an engineering simulation instead of price data, Footnote No. 175 the Edison "swing capacity model" discussed above ignores opportunity costs incurred by low cost
producers and fails to define a cognizable relevant market. Similarly, SCUPP cites a
vertical integration model which assumes that inputs are consumed only by suppliers in the
endproduct market. Footnote No. 176 That assumption does not hold in this case, where core and other
noncore customers consume the vast majority of the gas transportation input gas-fired
plants used to generate the wholesale electricity endproduct. Because both models assume
that all suppliers employ the same technology to produce the endproduct, they also fail to
account for other sources of competition in the wholesale market (e.g., hydro and coal
generation plants). Footnote No. 177 Finally, and most important, neither model reflects the incentives
of suppliers offering a price-regulated output, such as electricity sold by the merged entity
under Agreement B.
Edison, SCUPP and other intervenors also allege that the merged entity could
"unfairly benefit" from vertical integration by manipulating wholesale electricity prices
after it purchased contracts in the futures markets. Footnote No. 178 Thus, they contend, the merged
entity would essentially trade on "inside" information. Footnote No. 179 As before, however, the merged
entity would still be unable to manipulate wholesale prices and the merger would not
enhance any existing ability of SoCalGas to profit in the futures markets. Footnote No. 180 Moreover,
adverse effects upon competition within the futures markets -- which are characterized by
their liquidity and ease of entry and exit Footnote No. 181 -- are extremely unlikely. Footnote No. 182 In any event, the
hypothetical conduct would be unlawful under the Commodity Futures Trading
Commission Act.
3.
The Kern River and Mojave Pipeline Purchase Options
Kern River claims that the merged entity can extract increased supracompetitive
profits in the wholesale electricity market by exercising its options to purchase in 2012 the
California operations of the Kern River and Mojave pipelines. Footnote No. 183 This theory, which relies
upon the swing capacity model, again overstates the significance of gas-fired generation
and ignores the ability of an independent SoCalGas to obtain available supracompetitive
profits. Footnote No. 184
Kern River also ignores the competitive nature of the purchase options, whose
effects should be assessed from the perspective of the original settlement agreements.
Economic efficiency considerations require courts to establish rights and obligations "ex
ante;" i.e., on the date on which a crucial choice was made. Footnote No. 185 In 1987, SoCalGas and
PG&E dominated transportation service markets in southern California. The purchase
options, which the applicants contend were integral to the settlements between the parties,
permit Kern River and Mojave to compete for those services from 1987 to 2012. If the
parties had not settled their dispute, entry by those two pipelines would have been delayed
and the subsequent competition they furnished would have been reduced. Abrogating the
purchase options now would reduce incentives of other firms to enter into similar pro-competitive settlements in the future.
In addition, the year 2012 effective date allows purchasers and alternative suppliers
a substantial period in which to respond the possible exercise of these options. Footnote No. 186 In any
event, predictions about competitive effects 15 years into the future are highly speculative,
particularly when they concern markets as dynamic as the rapidly changing gas industry. Footnote No. 187
We conclude that the purchase options, which contemplated increased competition within
the intrastate market and which will not endow the surviving entity with additional market
power, should not be abrogated by the merger.
4.
The Applicants' "Remedial Measures"
Although this vertical integration does not "create" market power, it could alter the
manner in which SoCalGas exercises its existing market power over intrastate
transportation services. SoCalGas now exercises market power by discriminating in the
price of services charged to gas-fired generation plants and other potential "bypass"
customers. The merger will not provide new opportunities for profitable price or non-price Footnote No. 188 discrimination. We are also not aware of any evidence that the merged entity
would use its market power to require simultaneous competitive entry into the gas and
electricity markets or to facilitate coordination between SDG&E and other WSCC
suppliers.
In fact, the remedial conditions proposed by the applicants will reduce the ability
of the merged entity to engage in either price or non-price discrimination. Those proposed
conditions expand FERC's requirement that Order 497 govern intrastate transactions
between SoCalGas and SDG&E and other marketing affiliates. Order 497 generally
requires interstate gas pipelines to treat their marketing and other affiliates and "similarly
situated persons" on a non-discriminatory basis. Here, the applicants will retain their
ability to price discriminate, but they have agreed to submit any planned discounts to the
Commission for approval. In addition, they have agreed to refrain from discriminating in
the provision of various types of services, including: the application of tariff provisions;
transportation scheduling, balancing, storage, or curtailments; the processing of
transportation requests; the disclosure of transportation information; and the offering of
intrastate transportation discounts. Footnote No. 189
B.
Horizontal Effects in the Intrastate Gas Transportation, "Gas Procurement" and
Retail Gas Markets
The principal horizontal feature of this merger is the consolidated ownership of the
applicants' gas procurement functions. Footnote No. 190 Both of the applicants purchase gas in the
interstate market for their core and some of their noncore customers and SDG&E makes
significant purchases for its electricity generation plants. In 1996, SoCalGas and SDG&E
gas purchases averaged 963 Footnote No. 191 and 255 Footnote No. 192 MMcf/d, respectively, while total production in
the relevant interstate market averaged 24,000 MMcf/d. Footnote No. 193 Thus, SoCalGas and the
merged entity would account for approximately four and five percent, respectively, of
purchases within the unconcentrated four basin gas market. We assume for purposes of
analyzing this merger that SoCalGas is among the largest purchasers in the western United
States. Following the Guidelines, we conclude from this assumed distribution of buyers
that the merger of the two companies will have an insignificant effect upon competition in
the interstate gas market. Footnote No. 194
The merger will also combine the two companies' partially deregulated non-core
gas retailing functions. Footnote No. 195 Although both applicants currently distribute gas to non-core
customers, PUC rules significantly restrict the ability of SoCalGas to compete for such
sales within its service area. Footnote No. 196 Moreover, neither firm has made non-core sales outside
its service area. Footnote No. 197 In 1996, total non-core sales in southern California averaged 1821
MMcf/d. Footnote No. 198 SoCalGas and SDG&E sales to non-core customers during that year averaged
58 and 144 MMcf/d, respectively. Footnote No. 199 We conclude that the consolidation of these non-competing, relatively limited operations will not adversely affect competition for non-core
retail services.
C.
Potential Competition for Intrastate Gas Transportation and Electric Retail Services
This merger may eliminate SDG&E as a limited potential competitor in the market
for intrastate gas transportation services. The demand for intrastate transportation in
southern California is approximately 1 Bcf per day for SoCalGas core customers, between
125 and 300 MMcf per day for SDG&E, Footnote No. 200 and approximately 1 Bcf per day for other
noncore customers. The Project Vecinos agreement between the applicants and other
evidence suggests, although not conclusively, that the threat of independent entry by
SDG&E has provided some discipline to this less than fully competitive, high-entry-barrier
market. We recommend that the Commission consider requiring SoCalGas to auction a
volume of transmission rights over its system equal to the average SDG&E load.
The courts recognize two theories under which a merger between potential
competitors may be challenged. The actual potential competition doctrine -- which is so
speculative that it has never provided the basis for a successful challenge Footnote No. 201 -- applies if the
acquiring firm would have "probably" entered a concentrated market, thereby providing
significant procompetitive effects. Footnote No. 202 SDG&E may present a "threat of competitive entry
by a bypass pipeline" and it may be an "attractive anchor customer" for pipeline
construction "within" California. Footnote No. 203 The courts, however, require showings of an intent
to enter Footnote No. 204 that go beyond evidence of generalized abilities and incentives. To avoid
speculation, Footnote No. 205 they also require a showing that entry will occur, not in the "reasonably
foreseeable" future, but in the near future. Footnote No. 206 We are not aware of any evidence that
SDG&E had current or even reasonably contemporaneous plans to enter the gas
transportation market.
1.
The Perceived Potential Competition Doctrine
A merger may also be challenged if the acquiring firm is a "perceived potential
entrant." This doctrine applies if the acquiring firm is "(1) perceived by existing firms as
a potential independent entrant and (2) has exercised a tempering impact on the competitive
conduct of existing sellers." Footnote No. 207 In this case, SDG&E may have tempered the pricing of
intrastate transportation services by threatening to bypass the SoCalGas system. Thus, in
1988, SDG&E considered building a pipeline to directly interconnect with the El Paso
system. Footnote No. 208 SDG&E considered at least two other bypass proposals during the next six
years. Footnote No. 209 Finally, in 1994, the parties entered into their Project Vecinos Revenue Sharing
Agreement, where SoCalGas agreed to reduce transportation rates by an amount equal to:
"the potential benefits that SDG&E would have received had it partially or totally bypassed
SoCalGas by utilizing transportation services from a pipeline constructed in Baja
California." Footnote No. 210
Despite this tempering effect, it is unclear if SDG&E is a current entry threat or if
the Kern River pipeline and other suppliers view SDG&E as a potential entrant to the
intrastate market. Because the Revenue Sharing Agreement remained confidential until
recently, Footnote No. 211 these other suppliers may not have recognized that SDG&E was considering
bypass alternatives. Similarly, because SDG&E would have to build dedicated facilities
to bypass SoCalGas, SDG&E entry or withdrawal may not affect price or output levels
elsewhere in the market. More important, SDG&E may not still be a potential supplier
of intrastate services. Although SDG&E would constitute a valuable "anchor tenant," Footnote No. 212
the perceived potential competition doctrine applies to suppliers, not customers, which
have the ability to compete with their merging partners. Unfortunately, the record fails
to clarify these issues.
If the Commission does conclude that SDG&E is a significant potential competitor,
we recommend that it require the merged entity to auction transmission rights over the
SoCalGas system equal in volume to the average SDG&E load which will be withdrawn
from the intrastate market. Following SCUPP, we suggest that buyers of those rights
obtain undivided interests based on contract paths "from an established point of receipt to
an established point of delivery." Footnote No. 213 Those auctioned rights will constitute an alternative
source of intrastate transportation, thereby offsetting the loss of SDG&E as a potential
competitor. We propose an auction, with a long run marginal cost (LRMC) minimum bid,
because it will ensure that the highest valued users receive these rights and because it will
help reimburse SoCalGas for losses in the value of its system. Finally, because the
competitive effects of SDG&E withdrawal from the intrastate market appears somewhat
isolated, we suggest that the Commission establish this auction in separate proceedings
following the completion of this merger.
2.
The Retail Electric Services Market
IID alleges that SoCalGas is a potential competitor for retail electric sales within its
gas distribution area. Footnote No. 214 For the actual potential competition theory to apply, entry must
have a deconcentrating or other significant procompetitive effect. This predicate effect
will not exist "if there are numerous potential competitors," because the elimination of one
of many "would not be significant." Footnote No. 215
As the applicants demonstrate, however, Edison and the Los Angeles Department
of Water & Power already provide retail services within that region and 92 other
companies, including eight of the leading firms in the industry, have already registered as
Energy Service Providers with the Commission. Footnote No. 216 Furthermore, SoCalGas has no
competitive retail affiliates and limited experience within the electricity industry. Footnote No. 217 There
is also no evidence that Pacific had "actual" plans to provide such services or that Pacific's
entry would have had significant procompetitive effects in any retail electricity markets.
We conclude that the elimination of SoCalGas as a potential supplier would not have a
significant effect upon competition in any California retail electricity market.
VI.
RETENTION OF JURISDICTION
This office recognizes the uncertainty of the transition to the restructured system of
wholesale electricity sales and transmission that will go into effect on January 1, 1998.
Although we believe it is unlikely, we acknowledge the possibility that out-of-state sellers
will fail to discipline the pricing of electricity sold by the merged entity. We do expect,
however, that SoCalGas will continue to provide intrastate transportation services to the
vast majority of gas-fired generation plants within southern California. In the unlikely
event that the merged entity can manipulate the PX price, plants supplied by the Kern
River and Mojave pipelines and plants subject to "take-or-pay" contracts may provide
valuable competition in the restructured market. Accordingly, we recommend that the
PUC, during its continuing review of the competitiveness of the wholesale market,
specifically examine the pricing practices of the merged entity and the relationship between
those practices and the operation of the SoCalGas intrastate transportation system. Thus,
we recommend that the Commission consider retaining jurisdiction over this merger for
a period of two years for the purpose of reexamining the limited questions of whether: (1)
the merged entity has used its intrastate system to manipulate the price of electricity it sells
in the wholesale market; and (2) whether abrogating the Kern River and Mojave pipeline
options and the take-or-pay options would limit the ability of the merged entity to engage
in such practices.
The only difficult factual issue raised by this merger is whether the applicants are
potential competitors in the intrastate gas transportation market. The merger has no
adverse "horizontal" effects because competition between the applicants is limited to such
areas as the vast interstate gas market and non-core gas retailing. Vertical effects are also
negligible because wholesale electricity offered by the merged entity will be subject to the
constraints of comprehensive price regulation mandated by ISO Agreement B and because
SoCalGas cannot significantly increase either the gas prices or the transportation rates paid
by southern California gas-fired plants. In addition, out-of-state WSCC sellers, which are
highly integrated with southern California during both peak and off-peak hours, would
defeat any attempt by the merged entity to manipulate wholesale electricity prices.
Edison's swing capacity model comes to an opposite conclusion by overlooking the
fundamental concept of opportunity costs.
Some evidence does suggest that SDG&E is a potential supplier of intrastate gas
transportation services. If the Commission finds that evidence persuasive, we recommend
that it consider, in proceedings subsequent to the completion of this merger, requiring
SoCalGas to auction a volume of intrastate transmission rights equal to the SDG&E load
which will be withdrawn from the market by this merger. This remedy would introduce
competition into the intrastate market, thereby offsetting any adverse effect of the merger
and reducing incentives to construct duplicative, "uneconomic bypass" facilities. Finally,
we recommend that the Commission retain limited jurisdiction over this matter for a period
of two years during which it can review whether the merged entity uses its intrastate
system to manipulate the price of electricity it sells in the wholesale market.
"Take-or-pay liabilities arise from a typical provision in a contract between an LDC and a gas
producer which obliges the LDC to take a minimum volume of gas from the producer or pay for it
anyway." Kelly, supra, 9 Yale J. on Reg. at 361 n.16. Order 436 "gave pipelines facing mounting take-or-pay liability the right to convert their sales obligations under their wellhead contracts to transportation entitlments from other suppliers." Fagan, From Regulation to Deregulation: The Diminishing Role of the Small Consumer within the Natural Gas Industry, 29 Tulsa L.J. 707, 721 (1994). FERC Order 500 attempted to resolve further disputes by, among other things, allowing the establishment of a "gas inventory charge" (GIC). Lyon and Hackett, Bottlenecks and Governance Structures: Open Access and Long-term Contracting in Natural Gas, 9 J.Law. Econ. & Org. 380, 387 (1993). Order 500, however, "fared poorly on judicial review." United Distribution Cos. v. F.E.R.C., 88 F.3d 1105, 1125-26 (D.C.Cir. 1996).

In fact, Edison argued that the capacity of the transmission system connecting California to out-of-state suppliers easily satisfies demand. Thus, for Edison, the lines from the desert Southwest "were never
constrained and [have been] never even particularly close to being constrained" (Joskow MBR, at II-20)
and the capacity of North to South lines have never been fully loaded. Joskow MBR, at II-20. Similarly,
"there has been an abundance of unused transmission capability into SCE's control area at . . . high
demand times--5,303 megawatts on average during summer peak hours, 6,056 megawatts on average
during summer mid-peak hours, and 6,165 megawatts on average during winter mid-peak hours." Joskow
MBR, at II-48.
The capacity of transmission lines from the Pacific Northwest includes 3200 megawatts over the
Pacific Intertie (PACI), 1600 megawatts over the California Oregon Transmission Project (COTP), and
3500-3800 megawatts over Path 15. Pace MBR, at 24, 26. Power over these lines flows to southern
California over the Midway to Vincent path. Joskow MBR, at II-21. Another path, the PDCI, "goes
around PG&E's area and directly interconnects the Pacific Northwest with southern California." Pace
MBR, at 24, 28. Although Path 15 can be individually constrained, these lines have so much excess
capacity in the aggregate that 95 percent of the time, over 2,374 megawatts of their capacity was unused
in 1995. Joskow MBR, at II-20. See also Pace MBR, at 25.

Edison alleges that the price of gas at the southwest border determines the price of gas coming from
Canada and Rocky Mountain basins because the southwest is the "marginal supply region for California."
Carpenter Direct at 24-25. It is true that prices at those basins are very strongly related. Leitzinger
Rebuttal at 13, 26. We conclude in the absence of evidence of collusion, however, that those highly
volatile prices are competitively determined. See Carpenter Direct at 27 ("gas prices vary significantly on
a daily basis").

In general, "there is but one maximum monopoly profit to be gained from the sale of an
endproduct." See Town of Concord, 915 F.2d 17, 23 (1st Cir. 1990) (noting that "several members of the
Supreme Court have pointed out [this] 'widely accepted' (albeit 'counterintuitive') economic argument").
It is for this reason that the "government's 1984 vertical merger guidelines are not concerned . . . with the
possible use of vertical integration to 'leverage' monopoly from one market into another." Areeda &
Hovenkamp, supra, par. 1015.1. See also 3A Areeda & Hovenkamp, Antitrust Law, par. 756b at 12;
Western Resources, Inc. v. Surface Transp. Bd., 109 F.3d 782 (D.C.Cir. 1997); Alaska Airlines, Inc. v.
United Airlines, Inc., 948 F.2d 536 (1991), cert. denied, 112 S.Ct. 1603 (1992).
Relying in part upon the single monopoly rent theory, Judge (now Supreme Court Justice) Breyer
rejected a claim in Town of Concord that the defendant utility manipulated the price of input generation and
transmission services to "squeeze" the plaintiff in the endproduct delivered wholesale electricity market.
Here, the endproduct is also delivered wholesale electricity, but the inputs are interstate gas, intrastate gas
transmission, and electricity transmission. "[A] price squeeze occurs when the integrated firm's price at
the first level is too high, or its price is too low, for the independent to cover its costs and stay in business."
Town of Concord, supra, 915 F.2d at 18. The swing capacity theory advanced by the intervenors
essentially alleges that the merged entity will "squeeze" the gas-fired plants served by SoCalGas. See Yap
Direct at 67. Because SoCalGas tariff rates are not binding for all noncore customers, this merger presents
a mixture of the regulated and unregulated cases analyzed in the Town of Concord decision.

In this case, Edison and the applicants rely upon swing capacity models to support their positions
on the questions of whether the merged entity would have the ability and incentive to manipulate California
electricity prices. The applicants' PROSYM/MULTISYM model, based upon assumptions listed on "four
inches of printout material," uses a "cost minimization approach . . . to identify the lowest cost mix of
generators available to serve the electric load." Hartman Trans. at 2434; Surrebuttal at 5. Inputs to the
model include "fuel prices, transmission line, and pathways, and the ratings on those pathways." Hartman
Trans. at 2434. From the resulting least-cost mix, the hourly marginal clearing price is "calculated based
on the marginal generator's marginal cost and allocation of that particular generator's commitment costs
during the peak period load period." Surrebuttal at 6. This model predicts that increased gas prices
(Hartman Trans. at 2459-2461) would reduce electricity sales by SDG&E and other southern California
gas-fired plants (Hartman Trans. at 2449, 2452), increase sales for plants located in other parts of the
WSCC (Hartman Trans. at 2449, 2452-55), and reduce revenues for the merged entity (Surrebuttal at 18).
Edison employed the Inter-Regional Electric Market Model (IREMM) of the WSCC to predict the
effect on California electricity prices of "changes in the price of gas delivered to the California border."
Graves Direct at 84. This model "segments" the market into California and the remainder of the WSCC
and "forecast[s] the market price of electricity by simulating power trades between electric utilities or
market areas based on opportunities to buy and/or sell electricity." Graves Direct at Attachment H. The
IREMM model predicts that "a 5% gas price increase translates to a 3.8% electricity price increase."
Graves Direct at 85.
For reasons discussed above, we conclude that both of those models are highly misleading because
of their failures to account for competition from low cost, out-of-state supplies. Both models also overstate
electricity revenues resulting from gas price increases because they assume the merged entity will receive
the PX price, instead of the levels set forth in Agreement B. We do note, however, that
PROSYM/MULTISYM, unlike IREMM, can simulate the effects of cost increases to gas-fired plants
located in southern California. Graves Trans. at 3408. We also note Edison's admission that a
hypothesized increase in electricity revenues resulting from higher gas prices would be more than offset
by reduced transportation revenues. Graves Trans. at 3407.
