Rethinking WEPEX: What's Wrong with Least Cost?

AFTER MUCH DISCUSSION AND INNOVATION, CALIFORNIA is scheduled to launch its new electricity market (known as WEPEX) on Jan. 1, 1998, and we have a chance to revisit the issues. In the earlier round of this conversation, now three years past, I argued that the debate contrasting pool and bilateral models for a restructured electricity market was missing the point. %n1%n

I had thought the pool versus bilateral debate would be over by now; having both would have solved it.

ISOs: A Grid-by-Grid Comparison

BY THE START OF 1998, FOUR INDEPENDENT SYSTEM operators already were in operation and conditionally approved: ISO-NE, PJM and California by the FERC and Texas by the state PUC. Three more were either pending before the Federal Energy Regulatory Commission or expected to be filed in the coming months (New York, Midwest and IndeGO in the Northwest). Three additional efforts to develop ISO proposals were under way (DesertSTAR, MAPP and SPP). The Southeast is now the only large region of the contiguous United States without an ISO concept.

Retail Choice: A Race to the Bottom

A recent article laments the slow pace of retail competition for residential gas sales in New York ("Blue Flame Blues: Gas Pilots Sputter at Burnertip," Oct. 1, 1997, p. 22). Besides the meager financial incentive for a New York residential customer to switch gas companies, there is another factor contributing to the slow headway being made by gas marketers: The New York Public Service Commission failed to establish a level playing field with just and reasonable terms of sale.

Unbundling, Take Two: No Effect on Risk

Robert Rosenberg in his comment on our paper makes a fundamental error regarding financial risk. (Rosenberg, "Unbundling Capital Costs: It Doesn't Add Up," Nov. 1, 1997, p. 46, responding to Maloney, McCormick, and Tyler, "The Wires Charge: Risk and Rates for the Regulated Distributor," Sept. 1, 1997, p. 26.)

Rosenberg claims that as utilities spin off into separate wires and generating businesses, risk will increase in both lines of business.

Unbundling: An Excuse for Cost Shifting?

The article "Risk and Rates for the Regulated Distribution," by Maloney, McCormick, and Tyler (Sept. 1, 1997, p. 26) was interesting. For people with the vested interests of the authors, unbundling offers the golden opportunity of reducing regulated rates without actually having a formal rate decrease. That comes about by shifting on paper as much revenue as possible from the regulated disco to the competitive genco, while of course leaving all the costs with which that revenue is associated within the disco.

Off Peak

WHEN THE CALIFORNIA PUBLIC UTILITIES COMMISSION approved a price-cap plan for Southern California Edison's distribution operations, it lamented the lack of a "distribution-only" study on productivity. So we prepared one.

Unlike electricity generation, electricity distribution will remain a regulated business. But the form of regulation likely will change to price caps, mirroring events in telecommunications regulation here and energy regulation abroad.

With price caps, rates are reviewed formally only at set intervals.

Courts & Commissions

WITH DIRECT ACCESS SCHEDULED TO BEGIN ON Jan. 1, 1998, California regulators are moving quickly to set up their long-considered policies on electric restructuring. The restructuring actions touch nearly every aspect of electric regulation in the state from financing decisions and rate design to the sale of generating assets and monitoring new capital additions.

In addition, restructuring has affected ongoing regulatory activities such as the development of performance-based rate making plans and pricing and rate designs for large incumbent utilities.

USE OF U.S. ECONOMY UPHELD FOR EQUITY CALCULATIONS

The Federal Energy Regulatory Commission, in seven rate cases involving interstate natural gas pipelines, has upheld a new policy on the appropriate long-term growth rate to be used in computing their return on equity. Five of the pipelines contested FERC's new policy, as announced in Opinion 396-b.

The Commission defended the rate-setting method, but decided to allow the pipelines a chance to prove why the rules should not apply to them. The contesting pipelines are: Trailblazer Pipeline Co. (Docket No.

Perspective

EVERYONE'S GOT AN OPINION ABOUT MARKETING affiliates. In the natural gas industry, a fierce debate has emerged, as rules are proposed to govern the relationship between utility and affiliate.

Affiliate transactions are already among the most regulated activities in the gas industry. According to the 1995-96 Compilation of Utility Regulatory Policy produced by the National Association of Regulatory Utility Commissioners, every state, except Nebraska, has jurisdiction over affiliate transactions involving a private- or investor-owned gas utility.

PITTSBURGH CHALLENGES MERGER; ALLEGES COLLUSION

The city of Pittsburgh has filed an antitrust lawsuit against Allegheny Power Systems Inc., and Duquesne Light Co., to stop the merger proposed by the two companies.

In its Sept. 29 court filing, Pittsburgh claimed the two utilities acted jointly to restrain trade. The city said the companies did this by agreeing to maintain higher rates for electric retail service at two industrial sites targeted for redevelopment zones pending their merger.
