Why India’s Wind Energy Map Shows a Concentration Problem?

India’s wind power map, as the numbers show, is dominated by just five states — Gujarat, Tamil Nadu, Karnataka, Maharashtra and Rajasthan — which together account for 85% of the country’s total installed wind energy capacity. Gujarat leads the chart with 27% (14 GW), followed closely by Tamil Nadu at 23% (12 GW). Karnataka, Maharashtra and Rajasthan each hold around 10–15%, while the rest of the country shares the remaining 8%.
At first glance, this is a success story for India’s renewable energy push — concentrated zones of high wind potential being harnessed effectively. But scratch deeper, and the figures also reveal an over-dependence on a handful of geographies.
Geography Dictates Opportunity in Wind Energy
Wind energy potential is not evenly distributed across India. The western coastline, the southern peninsula and certain inland corridors have the most favourable wind speeds and conditions. Gujarat’s long coastline and policy-friendly environment have propelled it to the top. Tamil Nadu, a pioneer in wind energy since the 1990s, continues to be a strong player despite land and grid integration challenges.
The concentration in these states is partly natural — dictated by wind maps — and partly policy-driven. States with proactive renewable energy policies, faster land approvals, better evacuation infrastructure, and investor-friendly terms have attracted more projects.
Infrastructure Challenges in Harnessing Wind Energy
A key issue emerging from this distribution is grid integration. Most of the wind-rich states already face periods of surplus renewable generation, leading to curtailment. The lack of adequate transmission capacity to move surplus wind power to deficit regions means potential green energy often goes untapped.
The national grid strengthening projects under the Green Energy Corridor initiative aim to address this, but progress has been uneven. Without robust inter-state transmission capacity, the benefits of wind-rich states will remain geographically limited.
Diversifying Wind Energy Sources in India
While the top five states will continue to anchor India’s wind expansion, the country must diversify its wind generation base. Offshore wind, particularly off the coasts of Gujarat and Tamil Nadu, has the potential to add large capacities without competing for onshore land. Low- and medium-wind-speed turbines could unlock projects in states currently underrepresented in the wind map.
Hybrid projects — combining wind, solar and storage — can also make wind viable in states with moderate wind potential, balancing seasonal generation patterns. This would help reduce over-reliance on a few states and distribute the economic and employment benefits more evenly.
Policy and Market Signals
The new Approved List of Models and Manufacturers (ALMM) for wind, mandatory quality standards for critical components, and the push for domestic manufacturing could make the sector more resilient. But to spread the footprint, the central government may need to offer targeted incentives for wind development in new states, similar to solar’s growth in Rajasthan and Uttar Pradesh.
Market design will also matter. Encouraging open access, green hydrogen-linked wind projects, and corporate PPAs could create demand in new geographies, easing the burden on the top five states.
The Road Ahead
India’s wind power success is real — but it is also regionally concentrated. To meet its 2030 non-fossil capacity target of 500 GW and maintain grid stability, India needs not just more wind power, but more geographically balanced wind power. That means investing in grid infrastructure, exploring offshore and hybrid models, and creating the right policy and market environment to draw in new players and new states.
The wind may blow strongest along the coasts, but a balanced renewable future will require it to reach the heartland.
