Mumbai, Maharashtra — Adani Energy Solutions Ltd (AESL) on Wednesday said it has emerged as the lowest bidder for a ₹4,700-crore transmission project in Maharashtra designed to evacuate up to 4,500 MW of renewable generation from neighbouring Karnataka and feed it into major load centres in the state.
Scope and components of the scheme
According to the company, the scheme will be implemented through a special purpose vehicle, Satara Power Transmission Ltd, and is expected to be completed within 36 months of award. The main elements of the project include:
- Construction of a 765/400 kV substation at Satara
- A Kolhapur–Satara 765 kV double-circuit transmission line
- Augmentation of the existing Kolhapur pooling station and allied transmission works
On completion, AESL said the project will add about 562 circuit kilometres of transmission lines and 9,000 MVA of transformation capacity to its network, taking the company’s cumulative transmission infrastructure to 29,739 ckm and 1,43,425 MVA transformation capacity.
Why Maharashtra stands to gain
State officials and power-sector analysts view the project as part of a wider effort to integrate renewable energy from resource-rich regions of southern India into the western grid. The scheme is also being promoted as support infrastructure for pumped-storage projects being planned or under development in Satara, Pune and the Mumbai Metropolitan Region (MMR).
Pumped-storage plants act as large-scale batteries that store excess renewable generation and release it during peak demand, improving grid flexibility and reliability. AESL’s bid underlines an industry push to couple long-distance evacuation corridors with energy storage to absorb variable renewable output.
Company statement and wider targets
In its announcement, AESL highlighted the scheme’s role in strengthening power flows between Southern and Western India and said it will improve grid stability while connecting renewable-rich regions to industrial and urban demand centres.
“The Satara transmission project will create a vital transmission backbone that supports both renewable energy evacuation and energy storage deployment, strengthening power flows between Southern and Western India,” said Kandarp Patel, CEO of Adani Energy Solutions Ltd.
Delivery timeline and procurement route
The project was awarded through a tariff-based competitive bidding process, AESL said. The company expects to complete construction within 36 months. No further procurement or tariff details were disclosed in the announcement.
| Parameter | Detail |
|---|---|
| Project value | ₹4,700 crore |
| Capacity to be evacuated | 4,500 MW |
| New transmission length | 562 ckm |
| New transformation capacity | 9,000 MVA |
| Implementation vehicle | Satara Power Transmission Ltd (SPV) |
| Expected timeline | 36 months |
Context: national targets and grid planning
The announcement comes as India pursues an ambitious goal of expanding non-fossil fuel capacity — a drive that requires parallel investment in high-capacity transmission corridors and storage. Large-scale evacuation links such as the Kolhapur–Satara double-circuit and high-voltage substations are intended to enable long-distance transfer of wind and solar power from generation hubs to demand centres in Maharashtra’s industrial belts and the MMR.
AESL framed the Satara project as part of that broader transition, saying it will facilitate both clean-energy flows and pumped-storage deployment that can help manage intermittency. The company already operates a substantial private transmission portfolio and said the new works will be added under its existing infrastructure holdings.
Local implications and next steps
For districts such as Satara and Kolhapur, the project will involve land acquisition, tower corridors and substation construction over the next three years. Local administrations will be engaged for right-of-way clearances, environmental compliance and coordination with state load dispatch and distribution utilities.
AESL did not provide a detailed schedule for civil works, environmental clearances or compensation packages. Authorities and the company will need to publish further project-level documents during the pre-construction phase.
