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.

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.

Rolling Blackouts Hit Las Vegas

LCG, July 3, 2001In Las Vegas yesterday, street lights went dead, air conditioners quit conditioning air and perhaps millions of incandescent bulbs blinked off as a power blackout hit Nevada for the first time.

Incandescent bulbs, ranging in size from the itty-bitty ones inside slot machines to big ones illuminating casinos and hotels, are important in Las Vegas, as are air conditioners.

While expected hot weather had Nevada Power Co. lining up power reserves early in the day, the problem hit when both 790 megawatt units of the nearby Mohave coal-fired power plant went down for as-yet-unexplained reasons. Nevada Power has a 222 megawatt ownership interest in the plant, which is operated and 50 percent owned by Southern California Edison Co.

Casinos were asked to conserve power and many dimmed their lights and fired up emergency back-up generators. When Nevada Power was forced to shed 100 megawatts of load in the middle of the afternoon, about 10,000 customers lost power.

Under price controls recently put into effect for the 11 Western states by the Federal Energy Regulatory Commission, the Las Vegas blackout should have triggered controls throughout the region, but no reports indicated their implementation.
