As India accelerates its renewable energy transition, Battery Energy Storage Systems (BESS) are increasingly being recognized as a critical technology for improving grid stability, optimizing renewable energy utilization, and enabling reliable power supply across sectors. While solar energy has already witnessed rapid adoption across the country, the next phase of the energy transition will depend heavily on energy storage technologies capable of balancing intermittent renewable generation.
At Intersolar India 2026, several companies showcased innovations aimed at addressing this evolving requirement. Among them was EVault Energy, an emerging player focused on developing scalable battery energy storage solutions.
During the event, Shweta Kumari, Sub-Editor of The Battery Magazine, interacted with Chaitanya Tulsyan, Partner at EVault Energy, to understand the company’s vision, product offerings, and its approach to supporting India’s growing energy storage ecosystem.
How has your experience been at Intersolar 2026 so far?
This is our first time exhibiting at Intersolar as we are a relatively new company. The response has been extremely encouraging. We did not expect such a strong footfall at our booth, but the engagement from visitors has been very positive.
Many people have visited the booth to understand more about battery energy storage systems. Since the technology is still evolving in terms of awareness, visitors are keen to learn how BESS works and how it can benefit their operations. Overall, the exhibition has been a great platform for us to introduce our solutions and connect with potential partners and customers.
What key trends are you observing in the energy storage market at this exhibition?
One interesting trend is that awareness around BESS is increasing, but many people are still in the early stages of understanding the technology.
In some ways, the current stage of energy storage reminds me of the early years of solar power adoption in India. Around 2012 or 2013, people had started hearing about solar energy, but many were still trying to understand how it could benefit them or how it could be implemented in their businesses.
Today, BESS seems to be in a similar phase. People are hearing about battery energy storage systems and recognize that they will play an important role in the future energy ecosystem. However, many are still exploring the exact use cases and how storage solutions can help optimize their energy consumption.
Could you explain the current operations and core offerings of the company in the energy storage segment?
Our primary focus is on battery energy storage solutions across different capacity ranges. Currently, we offer battery packs starting from 5 kWh and going up to 5 MWh, which allows us to cater to residential as well as commercial and industrial energy storage applications.
We are also in the process of setting up a manufacturing facility in Ahmedabad, where we are developing a production line with an expected capacity of around 3 GWh annually. The facility is expected to become operational later this year.
At present, we source certain components such as inverters from third-party manufacturers and integrate them within our solutions under our brand. This allows us to focus our efforts primarily on the battery segment, which we believe will be one of the most important components of the future energy ecosystem.
How do your solutions differentiate themselves from other players operating in the BESS market?
As a relatively new entrant in the industry, one of our key priorities is to build trust with customers. We aim to achieve this through product reliability, extended warranties, and strong after-sales service.
For instance, we currently offer a seven-year warranty on our battery systems, which is longer than the typical five-year warranty offered by many players in the market. This additional warranty helps provide greater confidence to customers adopting our solutions.
We also emphasize local service capabilities. Since our battery packs are manufactured locally, customers do not have to rely on overseas support teams. Our in-house service team can address technical issues quickly, typically within 24 to 48 hours. This focus on service responsiveness is one of our key differentiators.
Which customer segments are you currently focusing on?
At present, we are primarily focusing on residential and commercial & industrial (C&I) segments. These segments allow us to deploy smaller and medium-sized systems while building operational experience and performance data.
Energy storage technologies require a strong performance track record, and these deployments help us generate valuable operational data that will support future expansion.
In the long term, we also plan to expand into utility-scale storage projects, which represent a significant opportunity in India’s evolving energy landscape.
Are there plans to participate in government tenders or large-scale storage projects in the future?
Yes, participating in government tenders and large-scale energy storage projects is part of our long-term strategy.
However, we believe it is important to first build a strong deployment base and accumulate sufficient operational data from our existing installations. Once we reach that stage, we plan to actively participate in utility-scale projects and government tenders related to energy storage systems.
India’s policy support for energy storage is increasing rapidly, and we see strong opportunities emerging in this space over the coming years.
