Green Energy Corridor Phase 3: Who Funds Rs 1.86 Lakh Cr?

Who Will Pay for India’s Green Energy Corridor III, and Will It Increase Electricity Transmission Costs?

The Green Energy Corridor project cost is split into Rs 1,36,378 crore for intra-state transmission and Rs 50,000 crore for 50 GWh of battery storage.

The Centre’s Central Financial Assistance (CFA) covers Rs 54,082 crore, roughly 29 percent of the total project cost. There has been made no disclosure by the Cabinet about who will fund the remaining Rs 1,32,323 crore.

Reading the scheme’s structure, the balance must come from State Transmission Utilities (STUs), private transmission developers and storage investors.

The CFA itself has four parts:

• The largest is Rs 45,005 crore for transmission, about 83 percent of the support and roughly a third of the transmission outlay.
• Another Rs 6,000 crore in viability gap funding for batteries.
• Rs 3,050 crore to cover earlier Green Energy Corridor commitments.
• Rs 27 crore pays for program management and grid studies.

What are the borrowing conditions for different project routes?

Greenfield lines go to private developers through competitive bidding, who raise their own debt and equity.

Brownfield upgrades follow a cost-plus basis, which keeps the financing burden with STUs. Those utilities will have to borrow, contribute to equity, or find other funding routes.

Guidelines of the earlier phase acknowledge that states face financial constraints in building intra-state transmission.

How Investors Target ROI

Under cost-plus, the state electricity regulator sets the tariff from actual spending plus a regulated return on equity. Those charges feed into distribution companies’ power costs and eventually retail tariffs.

The government says the CFA will offset transmission charges and keep power costs down, but with the Centre covering about a third of transmission capex, two-thirds still must be recovered from users.

Impact on consumers

The impact will likely be uneven. Industrial and commercial consumers, who pay transmission and open-access charges, may feel increases first, while regulators tend to cushion households.

Against that, less curtailment and cheaper renewable supply could offset part of the cost. This is an analysis, not an official projection, and the net effect will depend on how well cost overruns are controlled.
