Revenue Potential and Returns for a 100 MW Solar Farm in 2026
A 100 MW solar farm could generate about ₹65.7 crore in annual gross electricity revenue under a base case using a 25% capacity factor and a realized price of ₹3 per kWh. Revenue can range from below ₹45 crore to more than ₹100 crore depending mainly on generation, tariffs, curtailment, and project configuration. Profit and ROI depend on construction cost, O&M, financing, land, transmission, degradation, taxes, and debt repayment.
A 100 MW solar farm's theoretical maximum is 876 GWh yearly, but actual output depends on irradiation, weather, equipment and grid conditions. At a 25% capacity factor, it would generate 219 GWh and earn ₹65.7 crore at ₹3/kWh. Capacity factors of 15%–30% imply revenues of ₹39.42 crore–₹78.84 crore at that price.
Tariffs from ₹2 to ₹5/kWh would produce ₹43.8 crore to ₹109.5 crore at 219 GWh. NREL data cited in the article show a median AC capacity factor of 24%, with projects ranging from 9% to 35%. India's installed solar capacity reached 168.04 GW by August 31, 2026, including 123.99 GW ground-mounted, while SECI-linked tariffs span ₹2.42–₹2.54/kWh and solar-plus-storage around ₹3.12–₹3.13/kWh.
A 100 MW solar farm's revenue range could affect investors, landowners, utilities, and local communities. Stronger generation or tariffs may improve project viability, potentially supporting jobs, land lease income, and cleaner electricity supply. Weaker output, curtailment, or low tariffs could reduce returns and slow new builds, affecting energy prices and grid planning. These outcomes depend on financing, transmission, and policy design, so impacts may vary by region and project.
