Delta Electronics India, a prominent provider of power management and smart energy solutions, has secured a significant order to supply 110 MW of bi-directional Power Conditioning Systems (PCS) to Prostarm Info Systems Ltd. for deployment in multiple Battery Energy Storage System (BESS) projects across India. The agreement covers the delivery of 100 units of Delta’s ‘Make-in-India’ 1.1 MW bi-directional PCS, which will play a key role in supporting large-scale energy storage initiatives being developed for utilities and power distribution companies nationwide.
Under the collaboration, Prostarm will deploy Delta’s PCS units across several utility-scale energy storage projects, including those being undertaken by Bihar State Power Generation Company Ltd. (BSPGCL) and Adani Electricity Mumbai Ltd. (AEML). A notable application of the systems will be in AEML’s 11 MW/22 MWh BESS project in Mumbai, while other units will support both standalone and grid-integrated energy storage facilities under Prostarm’s development portfolio.
The deal represents the largest scale deployment of Delta’s locally manufactured PCS solutions in India’s fast-growing energy storage sector. Delta’s PCS units are designed and produced at the company’s manufacturing facility in Krishnagiri, Tamil Nadu, reinforcing the company’s commitment to the Make-in-India initiative and localisation of advanced clean energy technologies.
PCS units are critical components in BESS projects, functioning as the interface between the battery and the grid. These systems enable bidirectional energy flow, support grid stabilisation services, and facilitate advanced functionalities such as peak shaving, photovoltaic smoothing, and ancillary grid services. Delta’s bi-directional PCS solutions are engineered for utility-grade energy storage and microgrid applications, offering high energy conversion efficiencies of up to 98.5 per cent, robust output capacity of up to 1,160 kVA per unit, and scalability through parallel configurations.
Commenting on the partnership, Mr. Niranjan Nayak, Managing Director of Delta Electronics India, said the engagement reflects the importance of combining global technology expertise with strong local execution to support India’s energy transition and sustainable growth agenda. He highlighted that the project underscores Delta’s strategy to strengthen its footprint in the country’s rapidly evolving energy storage landscape.
Mr. Ram Agarwal, Whole-Time Director and CEO of Prostarm Info Systems Ltd., noted that the collaboration aligns with Prostarm’s mission of delivering advanced, technology-driven energy solutions that empower utilities and accelerate the integration of renewable energy. He emphasised that partnering with a global technology provider like Delta enhances the company’s ability to deliver reliable and high-performance solutions at scale, a key requirement for supporting India’s clean energy goals.
Supporting this view, Mr. Rajesh Kaushal, Vice President of Delta’s Energy Infrastructure Business Group, described the engagement as a milestone for Delta’s PCS business in India, reflecting a shared vision between the two companies and a strong strategic partnership built on localisation, performance, and reliability. Mr. Prateek Srivastava, Vice President and Business Unit Head at Prostarm, added that the collaboration also reinforces the importance of Make-in-India manufacturing and innovation in delivering customised energy solutions.
As India accelerates deployment of energy storage technologies to enable higher renewable energy integration and greater grid stability, partnerships such as this are expected to play a key role in scaling infrastructure capacity. Energy storage systems, including BESS solutions, are increasingly recognised as essential for supporting grid flexibility, reducing curtailment of renewable generation, and enhancing power system resilience.
