Solar Park Open Access: How C&I Consumers Can Save 40% on Power Bills

Industrial and commercial consumers are increasingly leveraging Open Access Solar Parks to reduce electricity costs by 30–40%. With India's Electricity Act allowing direct procurement from private generators, Open Access has never been more accessible.

The Power of Open Access

Open Access is a regulatory provision under Section 42 of the Electricity Act, 2003 that allows large consumers (typically with a connected load of 1 MW or above) to procure electricity from any generator of their choice — not just their local DISCOM. This creates a competitive market for power procurement, enabling C&I consumers to source affordable, clean energy directly from solar parks.

India added 7.8 GW of solar Open Access capacity in 2025 alone, driven by surging demand from manufacturers, commercial real estate developers, and data centres seeking to reduce energy costs and meet sustainability commitments.

How Much Can You Save?

The savings potential from Open Access solar depends on the state, applicable charges, and the consumer's load profile. As a general guide:

• Grid tariff (commercial/industrial): ₹7–10 per unit in most states
• Open Access solar tariff: ₹3.5–5 per unit (inclusive of wheeling, banking, and applicable surcharges)
• Savings potential: 30–45% reduction in electricity bill

For an industrial consumer with a monthly electricity bill of ₹50 lakh, switching to Open Access solar could save ₹15–20 lakh per month — amounting to ₹1.8–2.4 crore annually.

Procurement Models

• Group Captive: Consumer takes a minimum 26% equity stake in the solar plant. Exempt from most Open Access charges in most states. Best for large industrial clusters.
• Third Party Sale: No equity requirement. Consumer purchases power from an independent developer under a long-term PPA. Applicable CSS and wheeling charges apply.
• Captive Power Plant: Consumer owns 100% of the plant. Maximum savings potential but requires capital commitment.
