Buy solar power at scale.
If your business consumes more than 1 MW of electricity, Open Access Solar is the most powerful tool in India to cut energy costs by 30–50% — without building a plant on your premises.

Buy power from a generator of your choice — bypass your DISCOM.
Enabled by India's Electricity Act 2003, Open Access allows any consumer with a contracted demand of 1 MW or more to purchase electricity from a generator of their choice.
In simple terms: your factory in Pune can buy solar power generated in Rajasthan and wheel it to your premises through the state transmission network.
You pay for the solar power (30–50% lower than your DISCOM tariff), plus transmission and wheeling charges. The net effective rate is almost always substantially lower than your current electricity bill — without building or owning any solar infrastructure.
Which one is right for you?
Third-Party Open Access
You sign a long-term PPA with a solar developer who builds a utility-scale plant specifically to supply your power. SLDC-scheduled transmission to your utility. Most common structure for large industrial consumers.
- ▸ Minimum: 1 MW contracted demand
- ▸ Savings: 25–40% on energy cost after all OA charges
- ▸ Best for: Manufacturers, large factories, SEZs with stable 24×7 baseload
- ▸ Tenure: 15–25 years with annual escalation of 2–3%
Group Captive Solar
Multiple companies collectively own a minimum 26% equity stake in a solar power plant. Powermore holds the balance. Each member receives power proportional to their equity — classified as captive consumers and exempt from cross-subsidy surcharge in most states.
- ▸ Minimum equity: 26% stake (₹2–5 Cr for large plants)
- ▸ Savings: 40–55% — best financial outcome under Open Access
- ▸ Best for: Industry associations, corporate groups, SEZs, RE developers
- ▸ States: Gujarat, Rajasthan, Karnataka, Maharashtra, AP
Trade on IEX for flexible peak-shaving
Procure solar from Indian Energy Exchange on a monthly or daily basis — great for peak load coverage and short-term flexibility while you finalise a long-term PPA.
