ISO Board Drops Spot Market Price Cap to $250

LCG, Aug. 2, 2000--In a rancorous meeting marked by accusations of price gouging by electricity generators and poor forward planning by utilities, the oversight board of the California Independent System Operator yesterday voted to lower the price cap on power sold in the spot wholesale electricity market from $500 to $250 per megawatt-hour.

The lower price takes effect next Monday.

The limit had been reduced from $750 to $500 only weeks ago, in response to high prices being passed through to customers of San Diego Gas & Electric Co., which no longer operates under the price freeze imposed by the California electric restructuring law.

Yesterday was the third time the oversight board had considered dropping the price cap to $250. On two previous occasions the board, after long meetings, sided with power producers who said that artificially low power prices would discourage development of new power plants in the state.

In news reported yesterday Duke Energy Corp., a North Carolina company that operates power plants in California, said it would provide state utilities with wholesale power at $50 per megawatt-hour under long-term contracts, if the law permitted it to do so.

Californias three big utilities are prevented from entering into such contracts by the electric deregulation law, which mandates that they buy all of their power through the California Power Exchange, a sister organization to Cal-ISO.
