Entergy has proposed closing one of its largest Arkansas coal plants by 2028 and making modifications to another to comply with EPA’s Regional Haze rule.

SPP's latest analysis of EPA’s draft Clean Power Plan indicates state-by-state compliance with the plan would result in nearly 40% higher costs than a regional approach.

The Supreme Court ruled that EPA acted “unreasonably” when it failed to consider costs before deciding to regulate mercury and other toxic emissions from power plants under the Clean Air Act.

Gas producers are “listening loud and clear” to environmental concerns about fracking, James Tramuto, vice president of governmental and regulatory strategies for Southwestern Energy.

FERC approved PJM's Capacity Performance proposal, a dramatic restructuring of the RTO's capacity market.

Increased use of renewable energy will depress energy prices, increase capacity prices and lead to early retirement of baseload plants, according to ISO-NE.

With its reliance on demand response and behind-the-meter generation increasing amid generator retirements, MISO plans to update the way it sets prices during emergency resource offers.

FERC said it expects sufficient resources to meet peak electric demand this summer despite coal-fired retirements, while NERC approved its summer reliability assessment.

MISO and ISO-NE said they have sufficient resources to meet summer demand but warned that their reserve margins are shrinking due to plant retirements.

Andy Ott, PJM’s executive vice president of markets, will replace Terry Boston as president and CEO later this year, PJM announced Wednesday.
