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.

Sunflower Files Application for New Coal-fired Unit
LCG, January 14, 2010--Sunflower Electric Power Corporation (Sunflower) submitted a new application to the Kansas Department of Health and Environment (KDHE) for an air permit to build an 895-MW, coal-fired unit at an existing electric generating station near Holcomb, Kansas.
KDHE is expected to review the application over the next three to six month and then issue a draft permit for public comment. The renewed effort to permit the facility follows a lengthy battle to install the new, coal-fired generating capacity.
Sunflower initially filed an application to construct the facility in 2006, when the governor was Kathleen Sebelius, the current U.S. Secretary for Health and Human Services. While governor, Ms. Sebelius denied an air quality permit for Sunflower's project and vetoed three measures submitted by the Legislature to overturn the decision to reject the permit.
In May 2009, Governor Parkinson, who replaced Sebelius, approved a settlement agreement with Sunflower that permits the construction of a single, 895-MW unit, rather than two, 700-MW units. With the settlement and subsequent passage of an energy plan supporting the coal-fired project by the Kansas Legislature, it appeared that the project would proceed to construction. However, last summer the United States Environmental Protection Agency (EPA) directed Sunflower to restart the permit process for the proposed unit.
