Peak power now costs 25% more for industry

Power from 5 pm to midnight costs 25% more; 9 am – 5 pm gets a 15–25% rebate.

Details

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.

From Apr 2026
Business & industry

Banked solar can only be used in solar hours

Banked solar can now be drawn only 9 am – 5 pm, and unused units lapse monthly.

Details

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.

Maharashtra policy 2025–36
Business & industry

Storage now required for new projects above 100 kW

New renewable projects above 100 kW must now include energy storage (BESS).

Details

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).

Income Tax
Business & industry

40% accelerated depreciation on solar

Claim 40% depreciation in year one, or go zero-investment with OPEX solar.

Details

Businesses can claim 40% depreciation on solar plants in the first year, which cuts tax and shortens payback. Or choose zero-investment OPEX solar and pay only per unit.

Stored energy beats peak tariffs

Peak power costs about ₹12/unit; energy from a battery costs about ₹6/unit.

Details

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.

FAQs

Business solar questions

What is the zero-investment (OPEX) model?

We invest in, install, own and maintain the plant on your roof or land. You pay only for the solar units you use, at a fixed tariff below your grid rate, with no upfront cost.

Can businesses claim tax benefits?

Yes. Businesses that own a solar plant can claim accelerated depreciation of 40% on solar power systems. Confirm with your chartered accountant.

What is the GST on solar now?

Since 22 September 2025, GST on solar panels and systems is 5% (down from 12%). On a typical turnkey EPC contract the effective rate is about 8.9%.

Do businesses get the PM Surya Ghar subsidy?

No. The central subsidy is for homes and housing societies only. Businesses benefit from 5% GST, 40% accelerated depreciation, open access and zero-investment (OPEX) solar.

Should we add a battery with our solar plant?

In Maharashtra, yes in most cases. Peak power now costs 25% more, banked solar can only be used in solar hours, and new projects above 100 kW need storage. A battery moves cheap daytime energy into the costly evening peak.
