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.

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.

BY WHAT AUTHORITY CAN STATES FAVOR RENEWABLE

energy in a restructured electricity market?

Renewable resource funding marks a major point of contention in utility deregulation. Environmental groups fear that without some form of compulsion or subsidy, or both, renewable resources will not survive in an energy economy based on least direct consumer cost. However, utilities do not want to be saddled alone with the chore of carrying all renewables to market.

Divide the grid by usage (em local vs. regional. Apportion costs accordingly, to energy customers by fixed charge, and power producers by flow and distance.

Traditionally, utilities have received transmission costs through an average, rolled-in access fee, or postage-stamp approach. In a deregulated environment, that approach will lead to distorted pricing.

And not just because of transmission-line congestion.

Much of the current debate over electric transmission pricing has centered on the various competing methods of congestion pricing, such as zonal vs.

The California Public Utilities Commission (CPUC) has authorized Pacific Gas and Electric Co., Southern California Edison Co., and San Diego Gas and Electric Co. to guarantee notes totaling $250 million for loans to two trust funds to support the development of computer hardware and software for the state's proposed independent system operator (ISO) and power exchange (WEPEX), but commissioner Jesse J. Knight has dissented, worrying about cost control.

As noted in a parallel story ("PUC Loans Would Bolster ISO, Power Exchange," Headlines, p.

But which one?

And how to adjust for different delivery points?FOR THE PAST 20 YEARS, THE WESTERN

Systems Coordinating Council (WSCC) has built a reputation for innovation in electric markets.

On January 1, 1998, California will "deregulate" the state's electric utilities. The Western Power Exchange (WEPEX) and the independent system operator (ISO) will start up, creating an open market for wholesale power.

The old shibboleth to some extent is literally true. The electric industry appears different from the natural gas industry in that demand must be matched immediately with production. No viable location comes to mind to put away some of that extra power until it is needed. But literal truth is not necessarily the whole story.
