MSETCL Launches 2000 MW Battery Energy Storage Project to Boost Maharashtra’s Clean Energy Future Published By Anupam Nath The Maharashtra State Electricity Transmission Company Limited (MSETCL) has announced an ambitious initiative to transform the state’s power infrastructure with a large-scale Battery Energy Storage System (BESS) project. The company has invited expressions of interest (EoI) from Engineering, Procurement, and Construction (EPC) partners to develop 2,000 MW/4,000 MWh of advanced BESS installations across Maharashtra.This landmark project signifies a major step forward in India’s renewable energy transformation, designed to stabilize the grid, enhance power reliability, and facilitate higher renewable energy integration from solar and wind sources.Bridging Energy Gaps with InnovationBattery Energy Storage Systems play a critical role in modernizing power grids. They store excess renewable power during low-demand periods and release it when demand spikes, ensuring smooth and stable electricity supply. MSETCL’s new initiative is expected to significantly reduce load fluctuations, cut carbon emissions, and improve energy efficiency across the network.With this project, MSETCL plans to actively participate in the Maharashtra State Electricity Distribution Company’s (MSEDCL) separate tender for similar BESS setups. The empanelment process will ensure the selection of experienced EPC developers, technology providers, and system integrators capable of executing large-scale clean energy projects under strict performance and safety standards.Key Highlights and RequirementsThe project includes robust guidelines for EPC contractors, emphasizing design, construction, commissioning, and maintenance of the BESS units.Completion timeline: 15 months from the award of contract.Performance standards: Annual system availability of at least 95%.Penalties: 0.5% of total contract value per week for delays, capped at 5%.Maintenance guarantee: Annual bank guarantee covering 4% of the project cost.To qualify, bidders must demonstrate prior experience with at least 20 MWh of BESS projects or the construction of high-voltage (220 kV+) substations within the last seven years. Financially, they must maintain a minimum average annual turnover of 2 billion INR over the past three years with a positive net worth.Supporting India’s Energy GoalsThe central government has encouraged states to develop standalone BESS projects under the Viability Gap Funding scheme through the Power System Development Fund. These projects are part of India’s commitment to achieving clean, reliable, and self-sufficient energy systems under the broader energy transition goals of 2030.As urban growth and industrial demand continue to rise, India’s adoption of large-scale battery storage will play a decisive role in balancing renewable integration and ensuring 24/7 power availability.MSETCL’s move not only supports grid modernization but also sets a milestone for other states to follow in advancing smart energy infrastructure. By investing in BESS technology, Maharashtra positions itself at the forefront of the national clean energy movement, paving the way for a future driven by innovation, sustainability, and power resilience.
