Adani Energy wins ₹4,700-crore line to move 4,500 MW into Maharashtra

Adani Energy Solutions said on Wednesday it had won a ₹4,700-crore transmission project to move up to 4,500 MW of renewable and storage power into Maharashtra. Reuters put the figure at 47 billion rupees, or $492.6 million at ₹95.41 to the dollar. The company was the lowest bidder in a tariff-based competitive auction.

The scheme is titled “Network Expansion Scheme in Western Region to Cater to Pumped Storage Potential near Satara (up to 4500 MW) – Part A.” It will sit in a special-purpose vehicle, Satara Power Transmission Ltd. The build window is 36 months.

What gets built

The filing lists a 765/400 kV substation at Satara, a Kolhapur-Satara 765 kV double-circuit line and upgrades at the Kolhapur pooling station. The package adds 562 circuit kilometres of line and 9,000 MVA of transformation capacity. After those additions AESL’s network would stand at 29,739 circuit kilometres and 1,43,425 MVA.

The commercial purpose is twofold. One is to take renewable power generated in Karnataka to load centres in Maharashtra. The other is to give pumped-storage plants around Satara, Pune and the Mumbai Metropolitan Region a path onto the grid. Kandarp Patel, the company’s chief executive, called pumped storage the piece that lets a high share of wind and solar run without the grid falling over when the wind drops.

The win lifts AESL’s transmission order book to about ₹85,000 crore. The stock closed at ₹1,583.70 on the NSE on Wednesday, down 0.68 percent. A single award of this size rarely moves the share on the day it is announced. The cash goes out over three years.

Why the corridor exists

India has a 2030 target of 500 GW of non-fossil capacity. Generation sites in Karnataka and pumped-storage valleys in western Maharashtra are useless if the 765 kV spine cannot carry the power at the hour it is produced or released. Part A is one slice of that spine. Other western-region schemes, including a separate Pune West GIS plan under PFCCL, point to the same bottleneck: Mumbai and Pune need firm evening power, and the storage plants that can supply it need a 765 kV door.

TBCB awards shift construction risk and tariff risk onto the bidder. AESL now has to buy land or right of way, raise the Satara yard, string the Kolhapur line and hit the 36-month clock or pay the liquidated damages in the transmission service agreement. The useful follow-up number is not the press-release megawatt figure. It is the first circuit-kilometre actually energised.
