India installed a record 37.9 GW of solar and 6.3 GW of wind in calendar year 2025, according to Ministry of New and Renewable Energy data reported by pv magazine India on 13 January 2026. Solar additions were 54.7 per cent higher than in 2024, and wind additions 85.3 per cent higher. Cumulative renewable capacity, including large hydro, reached 258 GW at the end of December. Solar accounts for about 53 per cent of that total, wind 21 per cent, large hydro 20 per cent, bioenergy 4 per cent and small hydro 2 per cent.
The record year answers some of the doubts raised in 2024 about whether India could step up its annual build towards the pace required for 500 GW of non-fossil capacity by 2030. It does not answer all of them. Our view is that 2025 was flattered by a policy deadline and by the completion of a backlog of old tenders, and that sustaining 40 GW a year or more from 2026 will depend on resolving the contracting and transmission bottlenecks that slowed projects in earlier years.
Inside the 37.9 GW
The solar total breaks down into 28.6 GW of utility-scale capacity, up about 54.6 per cent year on year, 7.9 GW of rooftop solar, up 72 per cent, and 1.35 GW of off-grid and distributed capacity, down 8.8 per cent.
The report attributes the surge in utility-scale installations to the commissioning of long-pending tenders awarded by central and state agencies, and to developers accelerating construction ahead of the deadline for the waiver of inter-state transmission charges. Projects commissioned after the waiver lapses pay transmission charges that raise their delivered cost. That gave developers a strong incentive to complete projects in 2025.
Open access, the route by which commercial and industrial consumers buy power directly from generators, accounted for more than 38 per cent of utility-scale installations. That is a striking shift. A large share of new capacity is now driven by corporate buyers rather than by state distribution companies.
Rooftop solar responds to PM Surya Ghar
About 60 per cent of the year's 7.9 GW of rooftop solar was installed in the second half, which the report links to the PM Surya Ghar: Muft Bijli Yojana programme. The scheme, approved in February 2024 with an outlay of 75,021 crore rupees, offers central financial assistance of up to 78,000 rupees for a 3 kW household system and aims to reach one crore households. A 72 per cent rise in rooftop installations in a year suggests the national portal and direct subsidy model are working better than earlier rooftop programmes.
Manufacturing passes 200 GW
The report notes that domestic module and cell manufacturing capacity crossed 200 GW by December 2025. That is far above annual domestic demand and makes India a potential exporter. It also reflects policy: production-linked incentives, the approved list of models and manufacturers, and duties on imports have pushed developers towards domestic equipment.
Manufacturing capacity of that scale changes the politics of deployment. A domestic industry with 200 GW of capacity and 38 GW of annual domestic demand needs either faster deployment at home or export markets. Expect industry pressure for more ambitious tenders and for support for exports, particularly to markets where US tariffs on Chinese equipment create openings.
Why 2026 may be harder
Three factors that boosted 2025 will weaken in 2026.
The transmission waiver deadline pulled projects forward. Projects that would otherwise have been commissioned in 2026 were accelerated into 2025. That creates a gap in the pipeline.
The backlog of old tenders has been partly cleared. Many of the projects commissioned in 2025 were awarded two or three years earlier and had been delayed by land, transmission or contracting problems. Once that backlog is worked through, installations depend on newer awards.
Contracting remains a constraint. A substantial volume of capacity awarded by central agencies has struggled to find state distribution companies willing to sign power sale agreements. The growth of open access helps, but it cannot absorb all the capacity India needs.
Wind's rebound
Wind additions of 6.3 GW, up 85 per cent, are the strongest in several years. Wind matters disproportionately for India because its output in states such as Gujarat and Tamil Nadu often peaks in the evening and during the monsoon, when solar is weaker. Hybrid tenders combining wind and solar, and firm and dispatchable renewable energy tenders that require supply in specified hours, favour wind. A sustained rise in wind additions would do more for India's evening adequacy problem than an equivalent rise in solar.
The 2030 arithmetic
In July 2025 the government reported non-fossil capacity, including large hydro and nuclear, of 242.78 GW out of a total fleet of 484.82 GW. Reaching 500 GW of non-fossil capacity by 2030 from that base requires roughly 257 GW in five and a half years, or about 47 GW a year. The 2025 total of 44.2 GW of solar and wind, plus modest hydro, bioenergy and nuclear additions, is close to that pace for the first time.
That is the most encouraging reading of the 2025 data. The less encouraging reading is that the pace was reached in a year with an unusual deadline effect. If 2026 falls back towards 30 GW, the required annual rate for the remaining years rises above 50 GW. Planners should treat 2025 as proof of capacity in the supply chain, not as a new baseline.
Our position
India's 2025 renewable build was a record and a genuine step up. It shows the industry can deliver more than 40 GW a year of solar and wind when projects are ready and incentives align. The growth of open access and rooftop solar, and the expansion of domestic manufacturing past 200 GW, are structural gains that will persist.
But a substantial part of 2025's performance came from a deadline-driven pull-forward and the clearing of an old backlog. To sustain and raise the pace, India needs transmission built ahead of generation, tenders designed around evening and firm supply rather than midday energy, and distribution companies able and willing to sign long-term contracts. The record year buys time. It does not remove the constraints.
