India Installed 40 GW of Solar and Wind in Nine Months. The Pace Is the Story.

In nine months, India installed almost 40 gigawatts of clean electricity generation, more power than the entire grid of most countries. According to new figures from JMK Research, the country added 35.2 gigawatts (GW) of solar capacity and 4.69 GW of wind between January and September 2026, with total installed renewable energy capacity reaching about 299.2 GW by the end of September. The numbers, reported this week by Asian Power and PV Tech, describe one of the fastest generation buildouts happening anywhere on earth.

Solar did nearly all of the work. Utility-scale projects contributed 24.4 GW of the solar total, rooftop systems added roughly 9.8 GW, and off-grid and distributed installations made up the remaining 1,041 megawatts. Wind, by contrast, managed 4.69 GW, down 5.5 percent from the same period last year, even as solar installations grew 19.5 percent year over year.

The geography of the boom

Two states are doing more than half the work. Gujarat led with roughly 12.9 GW of combined solar and wind additions between January and September, followed by Rajasthan at around 9 GW and Maharashtra at about 3 GW. Together, Gujarat and Rajasthan accounted for approximately 55 percent of all new capacity, and the top five states (adding Tamil Nadu and Andhra Pradesh) contributed about 76 percent. This is a buildout with an address, and the address is western India, where high irradiation, available land, and existing transmission corridors converge.

India installed 39.9 gigawatts of solar and wind in nine months, enough to push cumulative renewable capacity to about 299 GW, with two states doing more than half the work.

The slowdown nobody is hiding

The quarterly pattern inside the headline number deserves attention. Utility-scale solar additions peaked at 12.12 GW in the first quarter, then declined to 6.87 GW in the second quarter and 5.4 GW in the third, less than half the Q1 level. Rooftop solar held up better, with roughly 9.8 GW added over the nine months and about a third of that arriving in the third quarter, leaving cumulative rooftop capacity at 33.4 GW. The divergence tells its own story: big ground-mounted projects are the ones facing the friction, whether from grid connection queues, land acquisition, or the handover from a deadline-driven first half (the inter-state transmission waiver cutoff in mid-2025 had pulled projects forward).

Wind, the laggard

The wind figures are the uncomfortable half of the report. At 4.69 GW for nine months, down 5.5 percent year over year, wind is adding capacity at roughly one-eighth the pace of solar. There is one bright spot: about 1.76 GW, or 37.5 percent of the nine-month wind total, was installed in the third quarter alone, suggesting the segment may have turned a corner late in the year. Even so, the mix tells the tale of India's transition so far. Of the 299.2 GW of total installed renewables, solar now accounts for roughly 57 percent and wind about 20 percent, with large hydropower (17 percent), bioenergy (4 percent), and small hydro (2 percent) making up the rest.

The factory behind the panels

Behind the installation numbers is a manufacturing push that is starting to show up in the data. Trade publication TaiyangNews reports that India added 50.6 GW of solar module manufacturing capacity in the first half of 2026 alone, with modules listed under the domestic-content approved list (ALMM List-I) reaching 225.5 GW. Gujarat again dominates, hosting nearly 45 percent of module manufacturing capacity. The constraint has shifted downstream: Mercom's CEO Raj Prabhu told the publication that domestic cell supply has not kept pace with module lines, with cell capacity listed near 35.5 GW, tightening supply and raising prices for compliant modules. The boom has a supply chain, and the supply chain has a bottleneck.

Can India hit 500 GW by 2030?

The arithmetic of the official target is straightforward. India aims for 500 GW of non-fossil capacity by 2030. At about 299 GW of renewables now, the country needs roughly 200 GW more in just over four years, or about 50 GW per year. The nine-month pace of 39.9 GW annualizes to roughly 53 GW, essentially on target, and JMK reported a pipeline of about 149 GW of solar, wind, hybrid, and storage projects as of June 2026, with another 48 GW in bidding. But pipelines are not power plants, and the Q3 slowdown in utility-scale solar is the reason the pace is the story rather than the total. This is the largest clean-generation buildout in the world after China's, and whether it accelerates or stalls will shape global deployment numbers for the rest of the decade. As the Energy Transitions Commission's October assessment argued, in sun-rich countries like India, solar paired with storage is the cheapest path to new power, which is why the rest of the world is watching these quarterly figures.
