India to Test Battery Storage at Coal Plants

India is trying out a new way to use its coal power plants.

They will be adding big batteries to some of them.

The batteries will store extra energy from solar power during the day.

Then, they can use that stored energy at night when the sun isn't shining, making sure there is enough power all the time.

This helps balance the power grid as more and more solar energy is used.

The plan is to test this at several coal plants.

This allows the plants to run smoothly, saving money and making them last longer.
