The energy profile of India is going through drastic changes owing to the massive penetration of renewable energy in the nation. Given that there have been several ambitious targets set for solar power generation and wind power generation in India, Battery Energy Storage Systems (BESS) have become crucial tools to ensure reliability, stability, peak load reduction, renewable energy integration, and energy security.
The Government of India has launched several utility-scale tender projects for storage systems, and more are being undertaken by state electricity boards and private players in the form of large-scale storage projects. This has made EPCs in India specialized in BESS as major facilitators of the nation’s shift towards clean energy.
The following companies provide solutions in terms of BESS for India.
Larsen & Toubro (L&T)
L&T continues to be one of the top EPC firms in India with experience across a variety of power infrastructure, transmission system, renewable energy, and industrial projects.
Given that energy storage projects have become increasingly bigger in size and scale, L&T is capable of taking on larger BESS projects based on their skills in engineering, project management, grid connection, and utilities infrastructure. This company has recently increased their involvement in clean and renewable energy, energy transition projects, and energy storage systems.
Tata Power Renewable Energy Limited (TPREL)
TPREL, the renewables subsidiary of Tata Power, has established itself as an important player in the Indian storage market. It has taken part in some of the solar plus storage projects and large-scale renewable energy projects.
Tata Power is very skilled in EPC work in renewable energy, energy transmission, and power distribution.
Sterling and Wilson Renewable Energy
Sterling and Wilson Renewable Energy, known worldwide for large scale solar EPC experience, now extends to include battery storage systems along with hybrid renewable energy projects.
The firm provides end-to-end solutions including engineering, procurement, construction and operations for both solar storage projects and utility energy projects. The global experience in projects and supply chain management helps Sterling and Wilson execute large scale BESS projects.
Fluence
Fluence is well-known worldwide for being an energy storage specialist. This company designs and deploys energy storage technology, digital optimization software, and executes energy storage projects.
Fluence is increasingly active in India as it works with utilities and renewable energy firms to develop energy storage projects in the country.
Jakson Green
Jakson Green about to become one of the most dominant clean energy companies in India. The firm is operating in renewable energy, green hydrogen, and battery storage.
With its full-service capability, the company can undertake the planning, engineering, and construction (EPC) and system integration of energy storage projects for industrial, commercial, and utility-scale clients.
AmpereHour Energy
AmpereHour Energy is one of the most prominent battery energy storage (BESS) system integrators in India, specializing in the storage business. The firm has focused exclusively on energy storage and provides full EPC and integration services for utility and commercial energy storage. It is a leader in energy storage system integration by providing hardware-agnostic integration for developers (utilities) and claims a portfolio of energy storage projects in the range of multiple gigawatt-hours.

AmpereHour is one of the most concentrated battery energy storage companies in the BESS space, unlike typical EPC companies that diversified into energy storage. (amperehourenergy.com)
Pace Digitek
One of India’s fastest-growing BESS EPC companies, Pace Digitek is a preferred contractor for utility-scale battery storage among major, state-owned, public sector enterprises.
In 2026, Pace Digitek won a BESS EPC contract from NTPC for 200 MW / 400 MWh in Bihar for the supply, installation, long-term maintenance, testing, and commissioning. (pv magazine India)
The firm has also been awarded a 250 MW/500 MWh BESS project from the Damodar Valley Corporation (DVC) and a 250 MW/500 MWh BESS EPC project from NLC India Renewables in Tamil Nadu.
What Makes a Leading Battery Energy Storage System EPC Company?
As the energy storage market gets better good Battery Energy Storage System EPC companies are known for things:
They are very good at engineering and putting systems together
They have done projects that supply power to lots of people
They work with companies that make battery technology
They can connect their systems to the power grid
They take care of their systems for a time
They have software to manage energy and control systems
They have a record of completing projects successfully
Future Outlook
India will probably become one of the energy storage markets in the world in the next ten years. The government is asking for companies to build energy storage systems and people want power all the time. This is an opportunity for Battery Energy Storage System companies.
Companies like L&T, Tata Power Renewable Energy, Sterling and Wilson Renewable Energy, Fluence, Jakson Green, AmpereHour Energy and Pace Digitek will be important in this growth. They are good at building energy systems putting batteries together and making infrastructure projects. This will be very important as India builds an flexible energy system that can support its goals for clean energy.
As the cost of batteries gets lower and the government makes more rules to support energy storage experienced Battery Energy Storage System EPC companies will become more important. They will be at the center of Indias steps in changing its energy system. Battery Energy Storage System EPC companies will play a role, in helping India achieve its clean energy goals.
