NEW DELHI:India’s non-fossil power capacity crossed 300 gigawatts on July 31 — more than half of everything the country has built. It is a genuine landmark. It is also a measure of what India can switch on, not of what actually reaches a household at eight in the evening.
The figure released by the Ministry of New and Renewable Energy is 300.50 GW, and it breaks down in a way worth reading slowly: 164.59 GW of solar, 58.14 GW of wind, 57.24 GW of hydro, 11.75 GW of bio-power and 8.78 GW of nuclear. Set against a total installed base of roughly 552 GW, non-fossil sources now account for more than 54 per cent of India’s generating capacity, and 60 per cent of the 500 GW the country has committed to install by 2030. The solar line carries the weight of the story on its own. It stood at 2.8 GW in 2014. In the last financial year alone India added 44.6 GW of solar and about 6 GW of wind — more solar in twelve months than the entire national fleet a decade ago.
Nameplate and reality: a solar plant’s rated capacity is what it produces in full sun. India’s demand curve peaks after the sun has gone.
A gigawatt of coal and a gigawatt of solar are the same number and not the same thing. One of them keeps working after dark.
At a Glance
• Non-fossil capacity: 300.50 GW as on July 31, 2026
• Solar: 164.59 GW · Wind: 58.14 GW
• Hydro: 57.24 GW · Bio-power: 11.75 GW · Nuclear: 8.78 GW
• Share of total: above 54 per cent of roughly 552 GW installed
• Against the 2030 target: 60 per cent of the 500 GW commitment
• Solar, 2014 to now: 2.8 GW to 164.59 GW
• Added in FY2025-26: 44.6 GW of solar and about 6 GW of wind

Here is the part the headline number does not carry. Installed capacity is a nameplate rating — what a plant delivers under ideal conditions. A coal unit can be asked to run at three in the morning; a solar farm cannot. India’s demand curve, meanwhile, does something inconvenient: it peaks in the evening, when air-conditioners, lights and cooking loads arrive together and the sun has already gone. So a country can hold more than half its capacity in non-fossil plant and still burn coal at the moment of peak demand, because the two facts describe different things. This is not a criticism of the achievement. It is the reason the next stage of the problem has moved somewhere else entirely — out of the generation business and into the two unglamorous industries that sit either side of it.
Those two are transmission and storage. India’s best solar resource is in Rajasthan and Gujarat; its heaviest demand is a thousand kilometres away, which makes high-capacity transmission corridors a precondition rather than an accessory. And shifting cheap midday solar into the seven o’clock peak is precisely what batteries and pumped hydro are for. The encouraging thing is that both are now where the policy energy is going, and both are industries India can build domestically — cell manufacturing, power electronics, transmission equipment, and the skilled installation workforce that a 44-gigawatt-a-year build rate already requires. The 500 GW target will be met on the present trajectory. The more useful question for the rest of the decade is a different one: how much of those 500 gigawatts actually shows up in the evening, and what India builds between now and then to make sure it does.
