ERCOT

R.J. Rudden Associates, Inc. (RJRA) estimates U.S. nuclear plant stranded costs at $65.5 billion ($1994) if electric industry restructuring is fully implemented in 1997.

The firm's analysis relied on historic cost and performance data for each facility, and on RJRA projections of regional competitive prices for capacity and energy. RJRA said a slower restructuring would reduce the investment at risk to between $46.3 billion (year 2000) and $23.2 billion (year 2010).

Central and South West Corp.'s subsidiary, Central Power and Light Co. (CPL), has proposed that all ERCOT nonnuclear utilities (em including IPPs, co-ops, and municipals (em become part of a competitive wholesale bulk power pool run by an independent system operator (ISO).

Transmission and distribution companies would continue to own and operate power lines, purchase all nonnuclear generation from the pool, and assume responsibility for actual delivery.

The Oklahoma Municipal Power Authority (OMPA) and the Public Utilities Board (PUB) of the City of Brownsville, TX, have announced their intent to form a municipal power pool spanning four states. OMPA is a full and partial requirements wholesale supplier to 35 municipal electric systems in Oklahoma. PUB owns coal- and gas-fired generation plants. The two entities offer a combined supply resource of about 800 megawatts, but rely on the transmission system of Central and South West (CSW).

In a recent article ("The Efficient Utility: Labor, Capital, and Profit," Sept. 1, 1995), Taylor and Thompson attempt to measure the

economic efficiencies of 19 investor-owned utilities.

The authors use a method of efficiency measurement proposed by M.J. Farrell in a pioneering paper published nearly 40 years ago.

Low Loads, Short Ride

Kevin O'Donnell's article "Aggregating Municipal Loads: The Future is Today" (Oct. 1, 1995) argues that residential and small commercial low-load-factor customers will do well in a competitive environment. Yes, I agree that the future for these customers is definitely today. Low-load customers will do much better in the short run. As long as excess capacity exists, sellers will price at little more than short-run marginal cost. Once excess capacity dries up, however, fixed costs will have to be paid.

Southwestern Public Service Co. (SPS) and Public Service Co. of Colorado (PSCC) have entered into a definitive merger agreement to form a public utility holding company that will cover one of the largest geographic areas in the nation. Size apart, the merger is unique in that SPS operates as part of ERCOT, and the two utilities are not interconnected. A new transmission line will be built to connect the two companies.

The new holding company will have combined annual revenues of $3 billion, and assets of $6 billion.

A couple weeks ago, on a beautiful Sunday morning, I picked up my briefcase and wandered down to the Potomac river shoreline to catch up on my summer reading list. There, on the Virginia side, gazing across the river at the Lincoln Memorial, Washington Monument, and Capitol dome, I gathered strength to tackle a foot-high mound of paper.

A new group, the Independent Power Suppliers of ERCOT (IPSE), has formed to speak for nonutility power suppliers that operate within the Electric Reliability Council of Texas (ERCOT). The stated mission of IPSE is "to promote the reliable operation of power systems within ERCOT, in which a competitive, environmentally responsible and profitable independent electric power industry can flourish." Membership is open to all nonutility generators (NUGs), cogenerators, and power marketers.

Federal Energy Regulatory Commission (FERC) administrative law judge Jerome Nelson has found the proposed merger between Central and South West Corp. (CSW) and the bankrupt El Paso Electric Co. (EPE) consistent with the public interest (Docket Nos. EC94-7-000 and ER94-898-000). However, Judge Nelson recommended that approval be subject to a FERC decision on a number of comparability issues. (The FERC had issued an earlier opinion imposing comparability as part of the merger deal, but excepting ERCOT members.

Average generation costs for the nation's electric utilities fell in 1994, primarily due to reductions in delivered fuel prices. Production costs declined by 3.5 percent, averaging just $1.89 per kilowatt-hour (Kwh) by year's end.

The WSCC is the only NERC (North American Electric Reliability) region where production cost increased (em 2.6 percent in 1994 (em as reduced hydro output in California was replaced by more costly natural gas-fired generation.
