The pattern in one line: India's wind fleet is growing at its fastest pace in years and just crossed 57 GW, with Gujarat now the clear national leader — but that entire fleet, added up across every state, still uses less than a tenth of what NIWE's own wind-resource atlas says is technically installable, and offshore wind, with a serious resource base, has commissioned nothing at all.

India's cumulative installed wind capacity reached 57,443.39 MW by the end of June 2026, per Ministry of New and Renewable Energy (MNRE) data. The pace of addition has accelerated sharply: roughly 6 GW of new wind capacity was added in FY2025-26, a 44 per cent increase over FY2024-25's additions. Globally, GWEC's Global Wind Report 2025 credits India with adding 6.3 GW of new wind capacity in calendar year 2025 — enough to rank third in the world for new installations that year — while India's total installed base ranks fourth globally, behind only China, the United States, and Germany.

Gujarat's 49% share of FY2025-26's new wind additions is the headline shift here: Tamil Nadu was India's wind pioneer and, as this blog's own earlier reporting on Tamil Nadu's NIWE numbers found, has roughly a third of its own assessed onshore potential built out — but Gujarat's newer, larger-scale build-out has now overtaken it as the single biggest contributor to the national total.

The National Institute of Wind Energy (NIWE) has surveyed India's onshore wind resource at progressively taller hub heights as turbine technology has improved, and the numbers climb sharply with each one: 302 GW of installable potential at 100m hub height, 695.5 GW at 120m, and 1,163.9 GW at 150m — all under a conservative 2 per cent land-availability assumption. Measured against the 120m figure, which is closer to where modern utility-scale turbines actually sit, India's entire 57.4 GW fleet represents barely 8 per cent utilisation of the national onshore resource NIWE itself has mapped. That gap isn't a wind-resource problem — NIWE has run over 900 wind-monitoring stations across the country to produce these atlases at 500m spatial resolution — it's a build-out problem, the same transmission, land, and repowering-pace constraints this blog's Tamil Nadu piece found driving the gap at state level, just visible at national scale.

India has an estimated 70 GW of technical offshore wind potential along the Gujarat and Tamil Nadu coasts, per GWEC's Global Offshore Wind Report 2026 — and has not commissioned a single offshore turbine to date. A 2025 tender was cancelled, stalling near-term progress, though a revised tender schedule is expected in the second half of 2026. GWEC's own forecast is candid about the timeline this implies: it expects India's first offshore wind projects to actually come online in the early 2030s, with total offshore capacity reaching only around 2 GW by 2035 — a small fraction of the 70 GW resource estimate, and a reminder that "technical potential" and "what gets built this decade" are very different numbers in India's offshore case specifically. (Offshore potential estimates have varied across studies and years in sourcing gathered for this blog's earlier Tamil Nadu piece too, and shouldn't be treated as one settled figure.)

Part of why the FY2025-26 growth rate jumped is a 7 December 2023 MNRE circular, the National Repowering & Life Extension Policy for Wind Power Projects, which superseded the original 2016 repowering policy. The policy exists specifically to let operators replace India's oldest wind turbines — many installed in the 1990s and 2000s at Tamil Nadu, Gujarat, and Maharashtra's earliest wind sites, running far below modern turbine efficiency and often below current hub-height standards — with newer, larger, more efficient machines even before the original turbines reach the end of their design life. Since older sites already have land, grid connections, and wind-resource data in place, repowering is generally faster to build than new-site development, and is one of the more direct routes to closing the gap between NIWE's atlas and what's actually installed without needing new land or new transmission corridors first.
