GK Energy has received a Letter of Award (LoA) from Maharashtra State Electricity Distribution Company Limited (MSEDCL) to develop a 150 MW/300 MWh Battery Energy Storage System (BESS) in Maharashtra.

The project will be developed with Viability Gap Funding (VGF) support and is aimed at strengthening energy storage capacity as Maharashtra continues to integrate renewable energy into its power system.

Under the award, the project is scheduled to be commissioned within 18 months from the signing of the Battery Energy Storage Purchase Agreement (BESPA).

The tariff for the project has been fixed at ₹2,38,000 per MW per month. Based on this tariff, GK Energy is expected to generate annual revenue of approximately ₹42.84 crore, excluding GST, for a period of 15 years from the commencement of commercial operations.

The project will comprise 150 MW of power capacity and 300 MWh of energy storage capacity, providing two hours of storage duration. The BESS is expected to support the integration of renewable generation and provide greater flexibility to the electricity system.

The award adds to GK Energy’s activities in the renewable energy and energy infrastructure sector. The company has traditionally been involved in decentralised clean-energy solutions, including solar-powered agricultural pumping systems, rooftop solar installations and distributed renewable energy projects.

The MSEDCL award also expands GK Energy’s presence in the rapidly developing Indian BESS market, where battery storage is increasingly being deployed to address renewable intermittency, peak demand and grid flexibility requirements.

The project will have both an execution component and recurring revenue over the long-term contract period. The company has stated that the transaction does not involve its promoter group and is not a related-party transaction.

The development comes as utilities and renewable energy companies increasingly use BESS projects to complement solar and wind generation. By providing the ability to store electricity and dispatch it when required, battery storage can help improve the flexibility of power procurement and renewable energy integration.

With the 150 MW/300 MWh award from MSEDCL, GK Energy is set to expand its portfolio beyond distributed renewable energy applications into utility-scale energy storage.

Solar Energy Corporation of India Limited (SECI) has initiated a 1 GWh pilot tender for peak power supply under a Contract-for-Difference (CfD) construct and proposed scaling the framework to 10 GW for the Indian power market.

The initiative is aimed at exploring market-linked contracting mechanisms that can support reliable renewable power supply during periods of peak electricity demand while enabling greater flexibility in power procurement.

Under the pilot, SECI is seeking to test the CfD construct for 1 GWh of peak power supply, with the objective of enabling renewable power to be available when demand is high. The initiative comes as India’s power system continues to integrate increasing volumes of renewable energy and energy storage.

Building on the pilot, SECI has proposed a 10 GW CfD framework for the Indian power market. The proposed scale-up is intended to examine how the mechanism could contribute to deeper, more flexible and efficient power markets.

The proposed framework could support greater flexibility in power procurement and facilitate the integration of renewable energy and storage. It could also help improve market participation and the utilisation of available generation resources through market-linked contracting arrangements.

The initiative could create opportunities for a broader range of participants across the power sector, including renewable energy and storage developers, generators, traders, power exchanges, distribution companies (DISCOMs) and large consumers.

SECI said the proposed construct could also enable new contracting and participation models, potentially creating additional avenues for ecosystem development as India’s power market evolves.

The CfD initiative is part of SECI’s broader efforts to explore innovative market mechanisms and support the development of more efficient power markets. The proposed framework is intended to complement the changing structure of India’s electricity sector while supporting the increasing integration of renewable energy and energy storage.

SECI has also indicated that continued policy guidance from the Ministry of New and Renewable Energy (MNRE) and other stakeholders will be important as the potential scale-up of the CfD construct is explored.

The move from a 1 GWh pilot towards a proposed 10 GW framework represents an effort to examine how market-linked mechanisms can evolve alongside India’s growing renewable energy capacity and the increasing need for flexible, reliable and efficient power procurement.

As India scales up its renewable energy capacity to meet its ambitious clean energy targets, utility-scale solar projects are becoming central to the country’s energy transition. While module efficiency often dominates discussions around solar performance, the inverter plays an equally critical role in determining how efficiently electricity is converted, managed and delivered to the grid.

Today’s utility-scale string inverters have evolved far beyond power conversion. Equipped with intelligent diagnostics, real-time monitoring, advanced grid support capabilities and integrated safety technologies, they enable developers to maximise energy generation, minimise operational downtime and simplify plant maintenance throughout a project’s lifecycle. As solar parks continue to grow and become more complex, selecting the right inverter platform has become a strategic decision that directly influences plant performance and long-term returns.

The following utility-scale string inverters have been selected based on their suitability for large-scale solar projects in India, considering factors such as energy conversion efficiency, grid support capabilities, intelligent monitoring, safety features, communication architecture, operational reliability, and cybersecurity protocols. While every project has unique technical requirements, these inverter platforms represent some of the most capable solutions currently available for utility-scale deployments.
