India installed 2.5 gigawatts (GW) of open access solar power in 2022, a 92% increase over the 1.3 GW installed in 2021. Installations reached an all-time high in 2022, according to the Mercom Research report titled "2022 Q4 & Annual Mercom India Solar Open Access Market," as numerous organisations and developers hurried to complete projects prior to the implementation of basic customs duty (BCD) and approved list of models and manufacturers (ALMM) regulations.
It noted that commissioning of projects delayed during the COVID-19 epidemic also added to the sum. According to the analysis, Karnataka will add the most solar open access capacity in 2022, followed by Tamil Nadu, Maharashtra, and the rest of India. "India added 293 MW of open access solar capacity in the fourth quarter of 2022, a decrease of 52% from the 615 MW installed in the third quarter. Quarterly installations decreased by about 10% from the previous quarter, it added.
In Q4 2022, more than 96% of all open access installations came from the top five states. With nearly 32% of the quarter's capacity gain, Karnataka continued to be the top state. The total installed solar open access capacity as of December 2022 was 7.7 GW.
It further stated that as of Q4 2022, the country has 6.6 GW worth of solar open access projects in various stages of development, with Andhra Pradesh, Rajasthan, Karnataka, Maharashtra, and Gujarat accounting for about 70% of the pipeline. Karnataka continued to be the leading state as of December 2022, representing roughly 36% of the total solar open access capacity. The next state, Maharashtra, accounted for more than 12% of all installations.
