AmpereHour Energy Launches 5 GWh BESS Manufacturing Facility in Pune to Strengthen India's Energy Storage Ecosystem

AmpereHour Energy has inaugurated a new Battery Energy Storage System (BESS) Manufacturing and Integration Facility at Chakan, Pune, marking a significant step in India's growing energy storage industry. The facility will manufacture and integrate Make in India cabinet-based and containerised Battery DC-AC Blocks designed for utility-scale renewable energy projects as well as commercial and industrial (C&I) applications. With a planned annual production capacity of 5 GWh, the facility is expected to support the country's rapidly expanding demand for advanced energy storage solutions.

The new manufacturing unit represents AmpereHour Energy's strategic transition from being primarily a BESS technology integrator to a full-fledged manufacturer of intelligent energy storage systems. The company stated that the expansion has been driven by years of operational experience in deploying battery storage projects, enabling it to incorporate real-world learnings related to system performance, safety, reliability, and lifecycle management directly into its manufacturing processes.

At the heart of the facility is AH-Suite, AmpereHour's proprietary digital manufacturing and quality management platform. The platform integrates factory quality assurance, subsystem engineering, product testing, and performance validation while providing end-to-end digital traceability for every battery energy storage system produced. The company believes this digital-first approach will improve manufacturing quality, accelerate commissioning timelines, and enhance long-term operational reliability.

The manufacturing platform is built around a hardware-agnostic architecture, allowing flexibility in integrating battery cells and components from multiple suppliers while optimising system design for diverse project requirements. Combined with AmpereHour's proprietary ELINA Energy Management System (EMS), the company's BESS solutions are designed to deliver intelligent energy management, advanced safety controls, renewable energy integration, peak demand management, and improved grid flexibility.

According to Rahul Shelke, Co-Founder and Managing Director of AmpereHour Energy, energy storage is emerging as one of the most critical pillars of the future electricity grid. He noted that the company's investment in domestic manufacturing builds upon years of experience as a system integrator and reflects a broader vision of developing safer, smarter, and more reliable battery storage systems tailored to real operating conditions. He added that the company's Make in India manufacturing platform and digital infrastructure are intended to strengthen India's long-term energy resilience while supporting global markets.

Ayush Misra, Co-Founder and CEO, said manufacturing was a natural evolution of the company's journey in the battery storage sector. He emphasised that modern energy storage extends beyond battery assembly and requires intelligent engineering, software integration, digital validation, and lifecycle optimisation to ensure consistent performance over many years of operation. By incorporating field experience into the manufacturing process through AH-Suite, every storage system undergoes comprehensive digital validation before deployment.

Battery Energy Storage Systems are becoming increasingly important as India accelerates the deployment of renewable energy. Since solar and wind generation are inherently variable, BESS installations enable surplus renewable electricity generated during periods of high production to be stored and discharged during periods of peak demand. This improves grid stability, reduces renewable energy curtailment, enhances power quality, supports frequency regulation, and reduces dependence on conventional fossil fuel-based peaking power plants.

The inauguration of the new facility also aligns with India's broader push to strengthen domestic manufacturing under the Make in India initiative and support the country's ambitious clean energy goals. The Central Electricity Authority (CEA) has projected a substantial increase in battery energy storage requirements over the coming decade to facilitate higher renewable energy penetration, improve grid reliability, and support India's target of expanding non-fossil fuel-based electricity generation capacity.

With a planned manufacturing capacity of 5 GWh, AmpereHour Energy's new facility is expected to contribute to the localisation of advanced energy storage technologies, strengthen domestic engineering capabilities, and reduce dependence on imported integrated storage systems. The investment also reflects the growing confidence of industry players in India's rapidly expanding BESS market, which is expected to play a pivotal role in enabling round-the-clock renewable power, supporting grid modernisation, and accelerating the country's transition towards a cleaner and more resilient energy system.
