FERC’s 12 Percent Reserve Riles Some Californians

LCG, November 20, 2002In an effort to prevent future energy crises, FERC plans to instate a 12 percent reserve requirement, but some utilities say such a move will cost too much.

The Federal Energy Regulatory Commission is considering setting the state energy reserve level at 12 percent as part of a larger effort to prevent events like the California energy crisis of 2000/2001, which landed Northern California utility PG&E in bankruptcy court.

However, some Californian officials object to the proposed measure, saying that forcing utilities to buy extra electricity will result in higher costs, the opposite of the intended effect of preventing high costs.

The California Consumer Power and Conservation Financing Authority asserts that FERC has gone beyond its authority in considering such measures, while representatives from Southern California Edison find minimum reserves necessary but object to FERCs proposal.

Some officials feel that the Independent System Operator should take responsibility for keeping the lights on.

Naturally, utilities will object to any new rules limiting their flexibility; FERC will have to determine whether or not the reserve requirement will be worth its cost to the utilities.

FERC will consider and solidify the reserve issue, as well as other facets of market design, next year.
