Singareni Collieries Company Limited (SCCL) is pioneering the use of Battery Energy Storage Systems (BESS) in India’s renewable energy sector. The company recently issued a tender to install a BESS at its 28 MW Solar Power Plant in Mandamarri, Mancherial district, Telangana.
Innovative Solar Storage Solution
The 1 MW/2.5 MWh Battery Energy Storage System (BESS) will be integrated with the Mandamarri Solar Plant, where it will store excess solar energy during the day and discharge it to the SCCL grid as needed to enhance grid stability and reliability.
The project, estimated at ₹50 million (approx. $602,004), has a comprehensive scope that includes design, engineering, installation, and commissioning. It also covers ten years of subsequent operations and maintenance, making it a significant undertaking that requires deep expertise in BESS implementation.
Bidders must have a proven track record of executing similar projects, both domestically and internationally.
The tender includes stringent pre-bid financial criteria, such as a non-refundable Earnest Money Deposit (EMD) of ₹500,000, a performance bank guarantee of at least ₹50 billion, and a nominal e-procurement transaction fee capped at INR 10,000 for tenders up to INR 50 Crores.
This venture highlights SCCL’s commitment to grid stability and sustainable energy. By pioneering BESS technology, SCCL is helping pave the way toward a greener future. The bid deadline of June 18, 2024, offers a unique opportunity for qualified firms to participate in this landmark project.
Driving Renewable Energy Adoption in Telangana
Telangana has emerged as a leading state in India’s transition to renewable energy, setting ambitious goals to achieve net-zero carbon emissions as part of its sustainable development program.
With an abundant solar potential of 20.41 GW, Telangana ranks second only to Jodhpur in terms of solar power capacity per unit area. However, the state’s current installed solar capacity of 3,621 MW accounts for only about seven percent of its total energy mix.
Solar power projects have been successfully implemented at 180 different sites across Telangana, often in innovative and efficient ways. This bottom-up approach empowers citizens to achieve greater energy self-sufficiency.
Reflecting this progress, the state’s renewable energy capacity has increased significantly, rising from 9.8% of the total energy mix in FY23 to 14.1% in FY24. With a total capacity of 6,335 MW, Telangana is now a national leader in renewable energy adoption.
To support these efforts, the government has introduced the Electric Vehicle and Energy Storage (EVES) Policy 2020-2030 to promote the adoption of electric vehicles and energy storage solutions. This policy aims to enhance the competitiveness of the electric mobility ecosystem and reduce greenhouse gas emissions.
Telangana’s investments in renewable energy are also drawing strong support from domestic and foreign investors. The state is actively exploring the potential of battery energy storage systems and grid-connected solutions to further enhance its renewable energy landscape.
Telangana’s proactive approach, favorable policies, and strategic investments have positioned it as a leader in renewable energy adoption among states of its size in India. The state’s commitment to a cleaner, greener future is commendable and serves as an inspiration for other regions.
