Don't want to build a wind farm? Calculate how much your factory or business can save on its electricity bill by buying equity in a group captive wind project instead of paying full DISCOM industrial tariff.
India has the world's 4th-largest installed wind capacity, concentrated in Tamil Nadu, Gujarat, Karnataka, Rajasthan, and Maharashtra — states with sustained wind speeds of 6–9 m/s.
Under Electricity Rules 2005, holding ≥26% equity and consuming ≥51% of a generator's output qualifies as "captive" — exempting the power from cross-subsidy surcharge and cutting costs 15–30%.
Wind's 20–30% capacity utilization factor beats solar's 18–20% because turbines generate at night and through monsoon — making wind and solar strong complements in a hybrid project.
Wind turbine capex has fallen to roughly ₹5.5–7 crore/MW installed, with O&M running 1.5–2% of capex annually — improving project economics year over year.
