"North Carolina, notably, ranks fourth in the nation for installed solar capacity, with nearly 10 gigawatts operating."

Ian Hapsias: The article fails to mention how long it would take to recharge the batteries after they’ve used their 4 hours of capacity.

The "duke, 3/5" photo above is old because it doesn't have the duct work along the side of the smokestacks that goes to the scrubbers and new smokestack. All of the sheet metal construction between the building and the striped smokestacks is probably for particulate removal, and it was probably added decades ago.

The current ash ponds are not lined. As part of the plant closure, "Duke Energy is required to excavate more than 80 million tons of coal ash from open, unlined impoundments at several locations and place the excavated coal ash in onsite lined landfills....Duke’s plans call for the draining and excavation of two coal ash basins at the site and then placing that ash in two double-lined landfills with a leak detection system surrounded by groundwater monitoring wells. The work will take place over the next 17 years."

This power plant has 19 million tons of the 80 million tons of coal ash of which Duke has agreed to properly dispose. The problem was that heavy metals such as mercury had leached out of the ponds and into the ground water. "Duke supplied bottled water to neighbors of the Allen plant and other coal ash dumps and in 2017 and 2018 paid $31 million to extend public water lines or add water filters at hundreds of homes statewide."

The plant was served by an industrial spur from the Southern Railroad that goes through Belmont, NC.
