India Curtails 2.3 TWh Solar Power in 2025
India had to stop using 2.3 TWh of solar power between late May and December 2025.
This happened because the power system couldn't handle all the solar energy being produced.
The country added a lot of new solar power capacity, but sometimes there wasn't enough demand or the grid couldn't handle it.
This led to the need to pay compensation for not using the solar power.
Experts say that to use more clean energy in the future, India needs to improve its power system's flexibility.
This means making other power sources more adjustable, building more storage for excess energy, and shifting some energy use to times when there's more solar power available.
India curtailed 2.3 TWh of solar power between late May and December 2025.
The curtailment was equivalent to 18% of the average monthly solar generation of 13 TWh.
India added 38 GW of solar power capacity in 2025, but curtailment was necessary due to transmission constraints and grid security concerns.
Compensation of ₹575-690 crore ($63-76 million) was paid through emergency mechanisms.
Experts recommend improving flexibility by adjusting other power sources, building more storage, and shifting demand to high solar availability periods.
