Indian clean-energy firm ReNew reports its strongest annual capacity additions yet, alongside significant strides in decarbonisation, ESG transparency, and market expansion across manufacturing and innovative green technologies.
ReNew’s latest integrated report suggests the Indian clean-energy company is trying to do more than add wind and solar capacity. It is using its annual disclosure to show how its business is widening across manufacturing, storage, transmission, energy markets and commercial and industrial power solutions, while also tightening its climate and sustainability targets. The report covers the year to 31 March 2026 and presents separate disclosures for its independent power producer and manufacturing operations.
That broader footprint is backed by scale. ReNew said it had commissioned 6.8 gigawatts of solar, 5.6 gigawatts of wind and 0.1 gigawatts of hydro, alongside 0.1 gigawatts, or 250 megawatt hours, of battery energy storage. In a separate release, the company said it commissioned about 2.4 gigawatts of new renewable capacity in FY2026, its strongest annual addition to date, taking its operating portfolio to roughly 12.6 gigawatts and its gross capacity to about 20 gigawatts as of 31 March 2026.
The company also says its own emissions performance is moving ahead of plan. ReNew reported a 25.6% cut in Scope 1 and Scope 2 emissions against its FY2021-22 base year, beating its FY2025-26 target of 23.5%. It also said it remained carbon neutral for those emissions for a sixth straight year and is still on a Science Based Targets initiative-validated path to net zero by 2040. On electricity use, 84% of power came from clean sources during the year, above its target and part of a longer-term aim to reach 100% clean electricity by 2030.
The report places that operational performance in a wider environmental context. ReNew said it generated 24.7 billion units of clean electricity during the year, which it claims supported about 21.2 million households and avoided roughly 20.8 million tonnes of carbon dioxide equivalent annually. The company also said the output represented about 8% of India’s clean-energy generation, underlining the scale at which private renewable companies are now contributing to the country’s power mix.
Beyond emissions, ReNew is broadening its sustainability framework to include climate resilience, biodiversity and resource use. The company said it completed its first climate risk assessment aligned with IFRS S2 and published its first TNFD-aligned Nature Action Report. It also said it kept zero liquid discharge across its operations, with two sites earning water-positive certification. In manufacturing, ReNew is targeting lower waste and energy intensity, reduced water use and 10% recycled material content by weight in modules by 2030.
Supply-chain scrutiny and data transparency also feature more prominently. ReNew said all critical suppliers have been assessed for ESG risk for three years in a row, while 41% now have Science Based Targets initiative-aligned net zero goals. The company also launched its first ESG Data Book and refreshed its double materiality assessment, identifying 18 material topics that are now mapped to measurable targets. ReNew said its ReSTART framework now includes 27 organisation-wide targets and eight manufacturing-specific goals.
People and technology are part of the same shift. ReNew said women made up about 18% of its workforce, rising to about 16% in manufacturing, while training investment increased 56% year on year. The company also said it has helped improve more than 1.95 million lives across 14 Indian states. On the technology side, it has introduced an AI governance framework and is expanding agentic and generative AI through its R.AI.SE programme, with digital tools delivering a reported 1% to 1.5% yield improvement across its wind and solar assets. The report also points to green hydrogen, green ammonia and green methanol as possible next steps, suggesting ReNew is positioning itself for a broader clean-energy market rather than only utility-scale power generation.
