EIA Analysis of Southwest Hydropower Generation Shows Record Lows and Slow Recovery

LCG, November 13, 2026--The U.S. Energy Information Administration (EIA) today issued an "In-Brief Analysis" highlighting the record lows for hydropower generation in the Southwest this summer. The prolonged drought conditions affecting the Colorado River Basin caused record low hydropower generation this summer in the Southwestern electricity supply region, which includes Arizona, New Mexico, and small parts of Nevada and California. Hydropower generation from April through August 2026 was a full 28 percent lower than the 10-year average and 19 percent lower than during the same period last year.

California ISO Approves Tehachapi Wind Transmission Project

LCG, July 30, 2004--The California ISO Board of Governors approved a new transmission project designed to increase transmission capacity from wind farms in the Tehachapi and Antelope Valley area to load centers in California. The current capacity of wind farms in the area is approximately 600 MW, with as much as 1,100 MW of additional wind projects planned, according to the ISO.

Southern California Edison is now expected to apply to the California Public Utilities Commission for approval to proceed and construct the 25-mile line, which is estimated to cost $94 million. The line may initially be energized at 230 kV and upgraded to 500 kV in the future. The new line could commence operations as early as December 2006.

The growth in generation from wind is driven in part by California's Renewable Portfolio Standard (RPS). The RPS requires 20 percent of the energy the Investor-Owned Utilities deliver to their customers to come from renewable resources by the year 2017.
