Indiana admits wind and solar need hydrocarbon backup
At least Indiana is being up front that wind and solar power generation need backup power systems from hydrocarbons, for when the wind doesn’t blow and the sun doesn’t shine.
=================
“CenterPoint Energy hopes to build two small natural gas plants to help the utility transition to more renewable energy. The utility plans to close most of its coal units and get more than 60 percent of its power from solar, wind and battery storage by 2025.
These smaller plants wouldn’t run all the time — instead they’d be used as a backup when there’s a high demand for energy.”
