AS U.S. ELECTRICITY MARKETS BECOME increasingly competitive, large industrial customers will discover many new choices. These choices include the opportunity to modify the amount and timing of electricity use in response to prices that vary from hour to hour. In addition, customers can sell certain electricity services, including operating reserves and load following, to the system operator. And industrial customers with cogeneration facilities can participate fully in bulk power markets, buying and selling energy and ancillary services in response to changes in spot prices.

The Federal Energy Regulatory Commission invited industry representatives to Washington, D.C., in July to talk about the electric utility industry's implementation of OASIS, or open-access, same-time information system, which is used to monitor and schedule electric transmission capacity.

It ended up with an earful about problems on the on-line system.

Gerry Cauley, of the industry's volunteer "How Working Group," said, "Overall, the OASIS does provide comparable access," and the system is seeing reservation activity at expected levels.

No clear signal as yet from new chair James Hoecker.

The Federal Energy Regulatory Commission had a busy day on July 30, but observers will have to wait until the fall to learn of any new wide-ranging policy initiatives planned by incoming chair James Hoecker, who has now succeeded Elizabeth Moler in the top post.

The end-of-summer meeting (em and Commissioner Donald F. Santa Jr.'s last (em was marked largely by a lack of controversy.

Locational marginal pricing, even if "complex," is well worth the benefits.

In two recent issues, PUBLIC UTILITIES FORTNIGHTLY featured editorials %n1%n on restructuring of the PJM Pool. Those two articles described proposals by the so-called supporting companies, %n2%n seven members of the Pennsylvania-New Jersey-Maryland Interconnection, to use a "locational marginal pricing" model for congestion pricing for electric transmission and to continue PJM as a "tight" power pool.

Your editorial in the June 1, 1997 issue ("PJM's Brave New World," p. 4) provided a perceptive analysis of the Pennsylvania transmission pricing debate. As you point out, standard economics defines the value of a transmission constraint as the difference between the price of electricity on one side of the constraint and price on the other side. There can be no dispute over this statement; however, this straightforward theory is not always correctly applied.

In the case of electricity, the marginal running cost (or energy price) cannot be used to determine the value of a constraint.

Nine members of the Pennsylvania-New Jersey-Maryland Power Pool filed a revised plan at the Federal Energy Regulatory Commission to establish an independent system operator for the Mid-Atlantic power market.

The utilities have been battling with lone dissenter PECO Energy over the details of the ISO.

The nine utilities, dubbed the "supporting companies," agree on the form that an ISO should take. In November 1996, the FERC had rejected ISO proposals by both parties as having failed to comply with Order 888.

The PJM Interconnection is what they call a "tight" power pool. As the Federal Energy Regulatory Commission has explained, tight power pools "extensively coordinate" their planning and operations, with central dispatch of generating plants. This coordination builds reliability--one of the long-term benefits, says the FERC, of a tight power pool.

Coordination also builds market power, however. And, as we all know from FERC Order 888, market power in transmission stands as "the single greatest impediment" to electricity competition.

Edison International elected former U.S. Secretary of State Warren Christopher to its board and its utility company's board, Southern California Edison. Christopher was elected chair of the executive committees of both boards. Howard P. Allen retired as chair and CEO.

John T. Coughlin, former Wisconsin Public Service commissioner, was elected chair of the PJM Interconnection L.L.C.

Former U.S. Department of State Legal Adviser Conrad K. Harper was elected to the board of both Public Service Enterprise Group Inc., and Public Service Electric and Gas Co.

More than a decade ago, working at the energy laboratory at the Massachusetts Institute of Technology, the late Fred Schweppe devised a novel scheme for pricing electric transmission. His solution? Do nothing. Simply ignore transmission.
