EV chargers & battery storage

For industrial and commercial consumers in Maharashtra, power from 5 pm to midnight costs 25% more, while 9 am – 5 pm units get a 15–25% rebate (rising to 20–30%). Storing cheap daytime energy for the evening is now worth real money.

For C&I, captive and open-access solar, banked daytime units can now be drawn only between 9 am and 5 pm, and unused units lapse every month. Right-size your plant and add a battery to use solar in the evening.

Under Maharashtra’s Renewable Energy & Energy Storage Policy 2025–36, new renewable projects above 100 kW, including open access, must install energy storage. A September 2026 MERC draft proposes the same for rooftop and behind-the-meter systems above 100 kW (50% of solar capacity for 2 hours, or 25% for 4 hours).

Peak-hour energy charges in Maharashtra are about ₹12/unit, while recent 4-hour battery-linked bids are around ₹6–6.5/unit. Shifting energy with a BESS can roughly halve your evening power cost.

PM E-DRIVE funds 72,300 public chargers. Government offices, residential colonies, hospitals and colleges get up to 100%; fuel stations, bus and railway stations and toll plazas get 80% of wiring/transformer costs and 70% of charger cost; malls, markets and highway amenities get 80% of wiring costs.

EV charging connections get a single-part tariff capped at the average cost of supply till March 2028: 0.7× during solar hours (9 am – 4 pm) and 1.3× at other times. Add solar and a battery to charge at the lowest cost.
