Electricity swallows 4‑8 % of Indian hospitals’ operating budgets. With grid tariffs rising 5‑7 % annually, CFOs are revisiting rooftop solar. Not for CSR slides, but pure economics.
Model hospital (600 beds, Bangalore)
- 1.2 MWp rooftop + car‑park solar, capex ₹4.8 cr post‑SECI subsidy.
- Net‑metered savings: ₹81 lakh/year at current tariff.
- Simple payback: 5.9 years; IRR 15 % even before carbon credits.
Layer a Building Management System (BMS) that throttles HVAC based on occupancy and air‑quality sensors and you shave another ₹34 lakh annually. Investors eyeing ESG mandates should note: hospitals topping GRESB scores trade at EV/EBITDA premiums up to 1.5×.
