Flow-based pricing ends

subsidies inherent in grid-wide,

postage-stamp rates.

n Order 888, the Federal Energy Regulatory Commission suggested 11 principles for forming an independent system operator, or ISO. In its third principle, the FERC offered this guidance on transmission pricing:

An ISO should provide open access to the transmission system and all services under its control at non-pancaked rates pursuant to a single, unbundled, grid-wide tariff that applies to all eligible users in a non-discriminatory manner.

Talk runs gamut from "rocket docket" to "Just go slow." A merger announcement kickstarted NARUC's annual conference last year. This year, in San Francisco, there was little difference in conference chatter. Only this time, MCI Communications Corp. and British Telecommunications Plc were the suitors, in a $20 billion corporate marriage.

Regulators had better get used to the "M" word, noted speaker John E. Hayes, Jr., chairman of Western Resources Corp.

PECO Energy Co. has filed its "Open Market Plan" at the Federal Energy Regulatory Commission (FERC) for restructuring the Pennsylvania-New Jersey-Maryland (PJM) power pool. PECO is the only member not joining a majority PJM restructuring order filed July 24 with the FERC.

The plan proposes an independent system operator (ISO) and electric transmission service priced on a regional, postage-stamp basis. The wholesale market would be based on bilateral transactions, with a residual pool for hourly energy.

Nine of the 10 electric utility members (excluding PECO Energy Co.) of the Pennsylvania-New Jersey-Maryland (PJM) Interconnection have filed agreements and transmission tariffs at the FERC, seeking to replace the pool with a competitive power pool that would set a next-hour spot wholesale power price (to vary by location), but also allow bilateral trading.

The majority proposal would set up an independent system operator (ISO). The tariff would support poolwide open access and comparable transmission service.

Paper trading is here, introducing an element of speculation in wholesale electric markets.The electric power industry joined the commodity markets on March 29, 1996, when power futures began to trade on the New York Mercantile Exchange (NYMEX). This first tentative step in the commoditization of electricity promises the emergence of a paper market for power, which, as in the case of other commodities, will likely prove substantially broader and more complex than electricity's physical market.

Two power pools (em one existing, the other inchoate (em have announced that they will file tariffs to price electric transmission as the difference in spot prices in the generation and consuming markets.

You've heard talk lately about the convergence of electricity and natural gas. That idea has grown as commodity markets have matured for gas and emerged for bulk power.

But some economists take a different view. They see the real convergence occurring between electricity and telecommunications. I'm not talking about the "smart house" or fiber-to-the-whatever. Instead, how is the product is created?

The deregulated power market will feature large numbers of buyers and sellers. Buyers will worry that prices will rise unexpectedly above current levels; sellers will worry that prices will fall unexpectedly. Some will be interested in fixed-price forward deals that protect them from these risks.

Nice Try!American Gas Association president and CEO Michael Baly's response to my article ("Electric Reliability: How PJM Tripped on Gas-fired Plants," May 1, 1995) concerning the January 19, 1994, rolling blackouts in the PJM power pool is damage control that fails. Here are the facts that Mr. Baly either ignores or distorts:

Forty percent of PJM's coal generation did not operate during the rolling blackouts. At least 80 percent of PJM's total generation where gas was the primary or sole fuel did not operate when needed.
