Dive Brief:
Dominion Energy South Carolina filed its modified integrated resource plan (IRP) on Friday, including a preferred scenario that would retire its coal generation fleet by 2030, and convert its Cope Station coal plant to natural gas.
The majority of Dominion s scenarios included large blocks of solar and solar-plus-battery-storage added between 2030 and 2048, with the potential to add 2,000 MW of solar from 2026 to 2048, up from the 973 MW of utility-scale solar already contracted, as well as 700 to 900 MW of battery storage.
Dominion submitted 14 different generation resource plans after regulators unanimously rejected its 2020 filing in December finding that the utility had misrepresented its fuel costs, and lacked demand side management resource options. The South Carolina Public Service Commission (PSC) specifically asked the utility to model an early retirement of its coal fleet, and three of Dominion s plans assume that scenario.
The EPA is considering plans for cleaning up legacy coal ash ponds. Tell them to make sure this toxic mess doesn t jeopardize our communities.
Amid this patchwork of farm fields fortified with gray matchstick forests sits two centuries worth of waste from the coal industry. Since the United States began burning coal on an industrial scale in the 19th century, upwards of 35 percent of the immolated material has fallen to the bottom of boilers as ash. That ash has then been removed, mixed with water, and placed in ponds and landfills. Over 3 billion tons of it now occupy more than 1,400 sites across the United States. According to the industry s own data, over 90 percent of these sites contaminate groundwater with almost two dozen heavy and radioactive metals including arsenic, lead, mercury, selenium, and radium at levels exceeding the EPA s health standards. A 2014 EPA study revealed that living next to a coal ash waste site increases one s risk of getting cancer from drinking grou

Many state energy regulators are pushing for less coal power and more renewables, forcing some electric companies to redo their long-term energy plans.

Utility regulators in several states are taking the unusual step of telling electric companies to redo their long-term energy road maps, a move that could dramatically alter the trajectory of fossil fuels and renewables.
