India’s tighter green power rules may hit clean energy investments, industry letters show

India’s planned rules requiring renewable producers to strictly adhere to their promised green energy supply to the grid would squeeze company earnings and slow investment in the sector, a review of industry letters showed on Wednesday.

The Central Electricity Regulatory Commission (CERC), in its draft published in September 2025, proposed tighter regulations for wind and solar power producers under the Deviation Settlement Mechanism.

The new framework aims to gradually narrow the permissible gap between the amount of electricity producers commit to supply and what they actually generate.
