LCG, April 13, 2026--The EIA today released an "In-brief Analysis" of U.S. coal-fired generating capacity retirements in 2025. A highlight of the analysis is that, during 2025, the electric power sector retired 2.6 GW of coal-fired generating capacity at four power plants, which is (i) the least since 2010 and (ii) 5.9 GW less than the planned retirement of 8.5 GW at the beginning of 2025.

LCG, April 10, 2026--The U.S. Environmental Protection Agency (EPA) announced yesterday a rule proposing several revisions to the federal regulations governing the disposal of coal combustion residuals (CCR) and the beneficial use of CCR. The EPA designed the rule to encourage resource recovery, allow for site-specific considerations in permitting, and provide regulatory relief while continuing to protect human health and the environment. The EPA will be accepting comments on the rule for 60 days after publication in the Federal Register, and it will also hold an online public hearing on the rule.

APS and Starwood Plan 290-MW Solar Project in Arizona
LCG, May 27, 2009--Arizona Public Service (APS) and Starwood Energy Group Global plan to construct a 290-MW concentrating solar plant (CSP) near Phoenix, Arizona. The Starwood Solar I plant is scheduled to be operational in 2013.
The facility will be designed, built and operated by Lockheed Martin, and it will be owned by an affiliate of Starwood Energy. APS will buy all of the electricity generated through a long-term purchase power agreement (PPA).
Starwood Solar I will employ a concentrated solar design that reflects solar energy with parabolic mirrors onto tubes filled with liquid. The heated liquid is used to convert water into steam that drives steam turbines that drive a generator.
The project includes a thermal storage system of molten salt to provide energy for power generation when direct solar energy is inadequate, which enables the plant to be dispatched when the sun is not shining. The project footprint covers a 1,900-acre site.
