Avista Takes Steps to Mitigate Power Shortage
LCG, Aug. 11, 2000--Avista Corp. yesterday announced three steps that will help it climb out of the hole it dug for itself when it allowed its inventory of available power to fall well below the demands of its native load.The most immediate relief will be provided by a 60 megawatt natural gas-fired turbine power plant near Spokane, Wash., which the utility brought on line yesterday. Ordinarily, the plant is held in reserve under an operating license that limits its use to a specified number of hours during periods of peak demand.Washington Gov. Gary Locke issued an energy supply alert order that allowed operation of the plant after the Spokane County Air Pollution Control Authority notified the governor that extended operation of the turbine would have no negative impact on regional air quality.The company also received approval from the Washington Utilities and Transportation for a special request for proposal for new power generation under which the WUTC agreed to waive normal time limits related to going out into the market to see what options are available for development of new generation resources.In the third step, Avista requested and received WUTC approval for deferred accounting of the financial devastation caused by the companys inability to cover power demand with either its own resources or generation arranged for in advance.The problem largely stemmed from the companys sale of its 175 megawatt interest in the coal-fired Centralia power plant earlier this year. When the plant was sold, Avista decided not to contract for replacement power, betting that spot market prices would be cheaper in May and June. It was a bad bet.The problem was made worse by trading activity in which Avista sold power short for the same period, meaning it agreed to deliver electricity without having electricity to deliver. It had to go into the spot market to cover its promises. Avista said the trading was unauthorized, but that didnt make it less painful.
