3 MW at a glance
The economics of a 3 MW plant, in plain words
Over its 25-year life a 3 MW plant in Gujarat generates about 49.9 lakh units a year. Under a DREBP PPA at ₹2.76/unit that is roughly ₹1.38 crore of revenue a year; on open access nearer ₹2 crore. After ₹0.21 crore of annual O&M, net income runs ₹1.17–1.79 crore a year, so the ₹12.3 crore build pays back in about 6.9–10.5 years and then earns largely profit. Claiming 40% accelerated depreciation shields roughly ₹1.23 crore of tax in year one, and undiscounted 25-year PPA revenue is around ₹34.5 crore.

Key considerations for a DREBP-scale plant
At 3 MW you are at the DREBP sweet spot — up to the 5 MW scheme ceiling, on a fixed 25-year PPA with the discom at a known tariff. It needs about 9–12 acres near a single 66 kV substation with evacuation headroom. The whole return hinges on that land-to-substation fit, so site selection and the DREBP registration matter more than shaving the EPC price.
