The government on Friday said more than 20 abandoned mines have been identified by state-owned CIL for evaluation and feasibility study for pump storage projects.
The information was shared by Coal India Ltd (CIL) during a diversification review meeting held by Coal Secretary Amrit Lal Meena.
State-owned NLCIL has also taken up a feasibility study on pump storage projects, the coal ministry said in a statement.
Pumped storage power plants use gravity to generate electricity using water that has previously been pumped from a reservoir in the pit into an upper reservoir.
