India added 1.1 GW of solar open access capacity in the first quarter (Q1) of 2025, down nearly 48% from 2.1 GW in Q4 2024. Installations were down 47% year-over-year (YoY) from over 2 GW, according to the Q1 2025 Mercom India Solar Open Access Market report. Domestic solar modules were scarce due to the rush to commission before the end of the financial year. The quarter saw a slowdown in the commissioning of solar open access projects due to a shortage of transmission infrastructure, delays in the clearance procedure for connectivity, and uncertainty regarding the interstate transmission system (ISTS) waiver.
