Sarala Project Works, Oriana Power, and Pace Digitek won Karnataka Power Transmission Corporation’s auction to set up 500 MW/1,000 MWh grid-connected standalone battery energy storage systems to manage peak power demand. Sarala won 50 MW at a tariff of ₹249,500 (2,913.02)/MW/month. Oriana quoted a tariff of ₹254,490 (2,971.28)/MW/month to win 50 MW. Pace won 250 MW, also at a tariff of ₹254,490 (2,971.28)/MW/month.

The Ministry of New and Renewable Energy mandated that only solar cells manufactured using undiffused wafers will qualify under the Domestic Content Requirement policy, effectively prohibiting the use of “blue” or diffused wafers. This is to ensure that the most critical stages of solar cell manufacturing—such as diffusion, printing, and metallization—are carried out entirely in India to strengthen the domestic solar industry.

India installed 6.9 GW of solar open access capacity in the calendar year 2024, 77% more than the 3.9 GW installed in 2023, a record for annual capacity additions, according to Mercom’s Q4 & Annual 2024 India Solar Open Access Market Report. While capacity additions in 2024 were driven by the availability of low-cost Chinese modules imported before the reimposition of the Approved List of Models and Manufacturers, state policies and consumer demand have added to the rise in open access solar transactions.

The Madhya Pradesh Electricity Regulatory Commission issued a new retail electricity tariff order for the financial year (FY) 2026, leading to an increase in power charges across all consumer categories.
