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.

TVA Approved to Produce Nuclear Weapon Supplies

LCG, September 24, 2002-NRC has given the TVA permission to produce radioactive products for use in nuclear weapons.

The Tennessee Valley Authority, which owns nearly 30,000 megawatts in generating capacity and serves utility customers in seven states, will now be able to put as many as 2,304 tritium-producing rods in its Watts Bar nuclear plant.

The plant will require 18 months to produce tritium, and the product will be shipped to South Carolina to serve a Department of Energy tritium plant being built there.

Tritium is an isotope of hydrogen, which can be used to adjust the nuclear reaction in nuclear bombs, although nuclear explosions derive the vast majority of their energy from reactions of either plutonium or uranium. Radiation from tritium cannot penetrate skin but constitutes a health hazard if the tritium is ingested or inhaled. The isotope has a half life of just 12.3 years, as compared with isotopes of uranium, which have half lives of hundreds of millions of years.

The Tennessee Valley Authority, which serves Alabama, Georgia, Kentucky, Mississippi, North Carolina, Tennessee, and Virginia, has also requested permission to produce tritium at a Chattanooga plant.
