Bonneville Power Administration, BPA/Lower Valley Transmission Project Record of Decision

摘要

As Administrator of the Bonneville Power Administration (BPA), I have decided to implement the Agency Proposed Action as described in the Final Environmental Impact Statement (FEIS) for the BPA/Lower Valley Transmission Project; a joint project between BPA and Lower Valley Power and Light, Inc. (Lower Valley). The Agency Proposed Action will solve a voltage stability problem in the Jackson and Afton, Wyoming areas. Lower Valley buys electricity from BPA and then supplies it to the residences and businesses of these areas. Since the late 1980s, Lower Valleys electrical load has been growing and loads are expected to continue to grow. During winter, a transmission line outage could cause voltage on the transmission system to drop below acceptable levels causing brownouts or, under certain conditions, a blackout. The new 115-kilovolt (kV) transmission line proposed in the Agency Proposed Action will maintain voltage stability and accommodate load growth.
