NEW DELHI: Several Indian states are seeking additional power allocations from the federal government to avoid outages as weak hydropower output and maintenance at some plants have reduced electricity supply during the night, two federal government officials said.

Rajasthan and Gujarat, among India's leading renewable-energy states, have sought additional supplies, along with other states including Maharashtra, Tamil Nadu, Andhra Pradesh, West Bengal, Uttar Pradesh, Chhattisgarh and Union Territory Delhi, the officials said.

The federal government typically has access to about 14 to 15 gigawatts of electricity from coal and hydropower plants that it can allocate to states during a shortfall.
