The Power Pool Council has approved a change to the Balancing Pool offer strategy for Clover Bar. Input to the Power Pool Council's decision was provided by stakeholders, the Alberta Department of Energy, the Market Achievement Plan Advisory Group, the Balancing Pool and the Market Surveillance Administrator.

The Balancing Pool will offer energy from the Clover Bar units, net of Ancillary Services commitments and minimum load requirements, into the hourly spot energy market at variable cost during all hours. In accordance with the Power Pool Council's decision, effective for trading on and after Thursday, June 14, 2001, variable cost for all hours will be determined using the projected daily spot price of natural gas.
