Coal India Wins Landmark Telangana Battery Storage Contract

Coal India Limited secured its debut renewable energy infrastructure contract in Telangana by winning a competitive tender for a major battery energy storage system. The state-backed coal giant will establish a grid-scale facility next to the state transmission utility’s substation in Choutuppal, located within the Yadadri Bhuvanagiri district.

The state generation utility, TG Genco, recently disclosed to the Telangana State Electricity Regulatory Commission that Coal India achieved a lower deployment cost than local miner Singareni Collieries Company Limited. Alongside Coal India, a private enterprise named Saras will construct a parallel storage facility in Maheshwaram. These dual installations represent a combined capital investment of ₹1,260.98 crore, delivering an aggregate capacity of 1,500 MWh at an optimized average development cost of ₹84 lakh per megawatt. This competitive pricing structure was achieved despite a recent surge in the international market value of specialized battery storage machinery.

The financial dynamics surrounding the tender became a subject of intense debate after Singareni Collieries Company Limited chose to abstain from the bidding process altogether. Singareni recently revealed that its existing 1 MW pilot project in Mandamarri successfully saved ₹26 lakh in electricity costs during its first 4 months of commercial operations. This facility allows the company to store surplus daytime solar generation within the battery network for strategic dispatch during peak demand hours rather than releasing it to the grid without financial compensation.

Industry analysts suggest that chronic liquidity constraints forced Singareni out of the race, as regional power distribution companies currently owe the miner ₹10,000 crore for thermal energy supplied from its Pegadapalli plant in Mancherial district. Furthermore, state utility TG Genco owes Singareni an additional ₹15,000 crore for raw coal procurement. Faced with severe capital shortages, the firm reportedly avoided raising fresh debt for infrastructure development, anticipating further payment delays from state utilities.

Future Outlook

The entry of national energy giants like Coal India into regional battery storage markets signals an accelerating transition toward hybrid grid management in India. As state distribution companies struggle with cash flow, competitive bidding from well-capitalized public sector undertakings ensures infrastructure development continues smoothly. These high-capacity storage installations will prove vital for balancing renewable energy integration as Telangana expands its solar power footprint over the coming decade.

FAQs

What is the capacity of the new Coal India battery project?

The project will feature an installed capacity of 187.50 MW, capable of delivering a total of 750 MWh of power over a 4-hour period daily to meet peak demand in Telangana.

Why did Singareni Collieries Company Limited skip the BESS tender?

Singareni bypassed the tender due to severe financial constraints caused by ₹25,000 crore in outstanding receivables from regional power distribution companies and TG Genco, leaving the company without sufficient capital to invest in new infrastructure.

What is the average cost of the new battery storage systems being built in Telangana?

The combined projects by Coal India and Saras will cost ₹1,260.98 crore, averaging approximately ₹84 lakh per megawatt, which is lower than the ₹86 lakh per megawatt previously spent by Singareni on its pilot plant.
