The Bonneville Power Administration on March 6 announced a new approach to addressing situations arising when too much energy is available for delivery. In these situations, which usually happen in the springtime when there is a lot of water in the Columbia River system, some generators must be turned off.
As the transmission grid operator, BPA is required to develop a method for determining which generators must be turned off first. BPA’s plan allows for displacing generators after all other reasonable actions are taken. While BPA operates the transmission grid, it also is responsible for generation units. In times of high water, federal system operators must run the federal hydroelectric plants in order to comply with environmental regulations to protect fish. The plan, which was submitted to the Federal Energy Regulatory Commission March 6, is based on input from regional stakeholders.
