Virginia-based utility Dominion Energy’s plan to turn an abandoned coal mine into a pumped storage hydro facility is unique, but not new.
North-Rhine Westphalia in Germany earlier this year said that it will turn its Prosper-Haniel coal mine into a 200-MW pumped storage facility. The consortium behind the project includes the University of Duisburg-Essen and mine owner RAG AG.
It’s too early in the process to know what the Dominion project capacity might be, but the company says it plans to pick a site early next year. Read about the Dominion project here, and learn more about the Prosper-Haniel project:
