Investments in India’s renewable energy (RE) sector surged to $1.23 billion (approx. Rs 102.2 billion) in August 2025, marking a 45 per cent increase from $848 million (approx. Rs 70.4 billion) recorded in the same month last year, according to a report by JMK Research.The sharp rise in funding reflects sustained momentum in the clean energy space, particularly in solar, wind, and battery energy storage systems (BESS).Among the largest investments in August was a Rs 31.84 billion long-term project financing secured by Acme Hybrid Urja, a subsidiary of ACME Solar, from REC Ltd. The funds will support its 280 MW firm and dispatchable renewable energy project.Additionally, Juniper Green Energy received Rs 17.39 billion in debt financing from the Indian Renewable Energy Development Agency (IREDA) to fuel the expansion of its operations and those of its subsidiaries.JMK’s report further noted that over 5,750 MW of renewable energy tenders were floated under the project development category in August. Also allocated during the month were 250 MW of firm and dispatchable renewable capacity and 275 MW / 800 MWh of BESS capacity across developers.Capacity Additions and Performance MetricsBetween January and July 2025, India added approximately:21,151 MW of solar capacity3,976 MW of wind capacityThis brought the total renewable energy capacity to 237.5 GW as of July. In comparison, during the same period in 2024, India had added 13,889 MW of solar and 2,339 MW of wind capacity.However, a separate report highlighted challenges in project performance during the last financial year (2024–25). According to Fitch Ratings:Wind load factors dropped by 8 per cent, marking the lowest performance since 2021–22.Solar load factors also declined by 3 per cent, signalling slightly lower-than-expected generation efficiency across installations.Despite these setbacks, sector analysts remain optimistic about future growth, driven by India's policy targets of 500 GW non-fossil capacity by 2030 and increasing private investment in advanced technologies like BESS and hybrid renewable systems.
