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.

Davis-Besse Repairs Increase in Cost and Duration

LCG, Oct. 7, 2002--Repairs underway at the Davis-Besse nuclear power plant in Ohio will require that the plant be out of service until early next year, and are expected to cost owner FirstEnergy more than $100 million above what was originally estimated.

The cost of installing a new reactor head, estimated at between $55 million and $75 million, will remain the same, according to the company. This year's work necessary to bring the plant online will likely increase in cost by $65 million, while next year's follow-up maintenance is seen as incurring $50 million more in expenses than previous estimates.

While the plant is out of service, FirstEnergy has a supply of energy to replace the nuclear plant's output, due to hedging. Of the repairs being performed, only the new reactor head will be capitalized. A leak of boric acid resulted in a hole within the protective reactor head.
