Delta Electronics India has announced a major supply agreement to deliver 110 MW of bi-directional Power Conditioning Systems (PCS) for battery energy storage projects being developed by Prostarm Info Systems Ltd across India. The deployment will support multiple utility-scale and standalone Battery Energy Storage System (BESS) projects, strengthening grid stability and renewable energy integration.
Under the agreement, Delta Electronics India will supply 100 units of its Make-in-India 1.1 MW PCS, marking one of the largest domestic deployments of locally manufactured power conditioning systems in India’s fast-evolving energy storage sector.
Project Overview
The PCS units supplied by Delta will be deployed across several BESS projects, including installations undertaken for Bihar State Power Generation Company Ltd (BSPGCL) and Adani Electricity Mumbai Limited (AEML).
Key project details include:
- Total PCS capacity: 110 MW
- Number of PCS units: 100
- Individual unit rating: 1.1 MW bi-directional PCS
- Application: Utility-scale and standalone BESS projects
- Deployment regions: Multiple locations across India
- Sector: Energy Storage / Power Infrastructure
Among the deployments is an 11 MW / 22 MWh BESS project in Mumbai for AEML, along with standalone BESS projects being developed by Prostarm in Bihar under the Battery Energy Storage Solution Power Developer (BESSPD) model.
Supporting Grid Stability and Renewable Integration
The deployment of advanced PCS infrastructure plays a critical role in enabling large-scale energy storage. These systems allow seamless bi-directional power flow between batteries and the grid, supporting essential functions such as peak shaving, renewable smoothing, and grid ancillary services.
By supporting both metropolitan and regional power networks, the collaboration contributes to India’s broader goals of enhancing grid resilience, integrating higher shares of renewable energy, and improving overall power system reliability.
Leadership Commentary
Niranjan Nayak, Managing Director, Delta Electronics India, said the collaboration reflects the importance of combining global technology expertise with local market understanding. He noted that the engagement with Prostarm for energy storage projects represents the largest deployment so far of Delta’s Make-in-India PCS solutions and reinforces the company’s commitment to long-term, customer-centric partnerships supporting India’s energy transition.
Ram Agarwal, Whole Time Director and CEO of Prostarm Info Systems, stated that the partnership strengthens Prostarm’s energy storage portfolio and aligns with its vision of delivering technology-led reliability and performance at scale. He added that the collaboration sets a benchmark for strategic partnerships in India’s evolving power sector.
Strengthening Domestic Manufacturing
Delta’s Power Conditioning Systems are manufactured at the company’s facility in Krishnagiri, Tamil Nadu, under the Make-in-India initiative. The PCS solutions are designed for utility-grade energy storage and microgrid applications, with a focus on high efficiency and scalability.
Key technical features include:
- Energy conversion efficiency: Up to 98.5 percent
- Output power capacity: Up to 1160 kVA
- Scalability: Up to five units operating in parallel
These capabilities make the systems suitable for large-scale grid applications as well as decentralised energy storage deployments.
Strategic Importance for Energy Storage Sector
Standalone and utility-scale BESS projects are becoming increasingly critical as India’s renewable energy capacity grows. Energy storage helps manage variability from solar and wind generation while ensuring reliable power supply during peak demand periods.
The Delta–Prostarm collaboration highlights the growing role of locally manufactured, high-performance power electronics in supporting India’s clean energy and grid modernisation objectives.
Why This Development Matters
This supply agreement reflects the accelerating momentum in India’s energy storage market and underscores several key trends:
- Rising deployment of utility-scale BESS projects
- Increased adoption of Make-in-India power electronics
- Strong collaboration between technology providers and system developers
- Enhanced grid reliability and renewable energy integration
Such partnerships are expected to play a central role in building the next layer of India’s power infrastructure.
Industry Outlook
As India scales up renewable energy capacity, demand for advanced power conditioning systems and grid-scale energy storage is expected to grow rapidly. Policy support, competitive bidding frameworks, and falling technology costs are likely to drive continued investment in BESS infrastructure.
Companies with strong manufacturing capabilities, localisation focus, and proven performance are well positioned to benefit from this growth trajectory.
