These systems are now being recognized as not just a backup solution, but as a critical component of energy management strategies in businesses.

BESS allows commercial enterprises to store energy generated from renewable sources such as solar and wind, as well as from the grid. This stored energy can then be used during power outages or periods of high demand, thereby reducing the reliance on fossil fuels and contributing to a significant reduction in carbon emissions.

The commercial sector, ranging from small and medium enterprises (SMEs) to large multinational corporations, is increasingly exploring the potential of BESS to enhance energy efficiency and sustainability. With the Indian government’s push towards a cleaner energy mix, businesses are now more motivated than ever to invest in BESS, not only as a means of achieving their net-zero goals but also as a cost-effective solution to energy management.

Market Dynamics and Future Potential

The adoption of BESS in India is growing at an unprecedented rate. According to industry estimates, the BESS market in India is expected to expand from $3.10 billion by the end of 2024 to $5.27 billion by 2029, with a compound annual growth rate (CAGR) of over 11.20%. Globally, the market for BESS is projected to increase from $44-55 billion in 2023 to an estimated $150 billion by 2030. These figures underscore the critical role that BESS is set to play in the global energy transition.

In India, several sectors are leading the charge in BESS adoption. For instance, the manufacturing, hospitality, and retail sectors are increasingly deploying BESS to manage their energy needs. This trend is driven by the dual pressures of rising energy costs and the need for uninterrupted power supply. Moreover, the falling cost of battery technology, particularly lithium-ion batteries, has made BESS a more attractive option for businesses.

The decline in the prices of lithium-ion phosphate (LFP) energy storage cells has been particularly significant. Prices have fallen from nearly $100/kWh in 2023 to $50-60/kWh, driven by increased manufacturing capacity in China and the reduction in raw material costs. This trend is expected to continue, further boosting the affordability and adoption of BESS in India.

Government Initiatives and Policy Support

The Indian government has been proactive in supporting the adoption of BESS through various initiatives and policies. The introduction of the Viability Gap Funding (VGF) scheme, which provides a 40% subsidy on the cost of BESS installations, has been a game-changer for the industry. This subsidy has made it more financially viable for engineering, procurement, and construction (EPC) companies to incorporate BESS into their projects, particularly in sectors such as manufacturing, where energy costs are a significant concern.

Moreover, the government has been issuing more BESS tenders to encourage the storage of excess energy generated from solar panels rather than transferring it to the grid. This policy shift is aimed at stabilizing the grid and ensuring a consistent power supply during peak demand periods, particularly in the evenings when solar energy generation is not possible. This move is expected to drive further growth in the BESS market, as businesses look to capitalize on the benefits of energy storage.

One of the key government initiatives driving the growth of BESS in India is the National Energy Storage Mission (NESM). Launched as part of the National Mission on Transformative Mobility and Battery Storage, the NESM aims to create a robust energy storage ecosystem in the country, focusing on the development of manufacturing capacity, the creation of a policy framework, and the promotion of research and development (R&D) in energy storage technologies. The mission is expected to play a pivotal role in the growth of the BESS market in India, by creating a conducive environment for the adoption of energy storage solutions.

Industrial Adoption and Case Studies

The adoption of BESS by industries in India has been driven by a combination of factors, including the need for energy security, cost savings, and environmental sustainability. Large-scale industrial projects, such as the planned BESS manufacturing unit by a leading Taiwan-based company and the development of four giga factories by a major Indian conglomerate, are further evidence of the growing importance of BESS in India's energy landscape.

In the manufacturing sector, companies have been quick to recognize the benefits of BESS in terms of cost savings and operational efficiency. For instance, a Pune-based energy solutions provider installed a 200kW/220 kWh battery storage system at a prominent vineyard in Nashik, allowing the winery to seamlessly switch between different energy sources, including the grid, solar power, and diesel generators. This system, which recharges during peak solar hours, provides the winery with an hour of power backup and has a lifespan of approximately 22 years. The installation has not only helped the winery reduce its carbon footprint but has also resulted in significant cost savings.

Similarly, in the hospitality sector, companies have been increasingly adopting BESS to enhance energy efficiency and reduce operational costs. For example, a leading beverage company’s plant in Chennai has integrated BESS into its energy management system, allowing it to store excess energy generated from its solar panels and use it during peak demand periods. This has helped the company reduce its reliance on diesel generators and lower its energy costs.

The Economics of BESS vs. Diesel Generators

One of the primary reasons for the growing adoption of BESS in India is the economic advantage it offers over diesel generators. While diesel generators are cheaper to purchase, their operational costs are significantly higher than those of BESS. The cost of energy generated from diesel generators can range from Rs 25-30 per unit, while solar energy stored in batteries costs between Rs 6-10 per unit. This significant difference in operating costs has made BESS a more attractive option for businesses looking to reduce their energy expenses.

Moreover, the operational efficiency of BESS is higher than that of diesel generators. Diesel generators require regular maintenance and have a shorter lifespan compared to BESS, which has a lifespan of 15-20 years. Additionally, BESS offers greater flexibility in terms of energy management, as it can be integrated with renewable energy sources such as solar and wind, providing businesses with a reliable and sustainable energy solution.

Challenges and Opportunities

Despite the numerous benefits of BESS, there are several challenges that need to be addressed to ensure its widespread adoption in India. One of the main challenges is the limited duration of power backup provided by BESS, which may require businesses to rely on diesel generators during prolonged power cuts. However, ongoing advancements in battery technology are expected to improve the performance and longevity of BESS, making it a more viable option for businesses in the long term.

Another challenge is the high upfront cost of BESS, which can be a barrier for small and medium enterprises (SMEs) with limited financial resources. However, the government’s Viability Gap Funding (VGF) scheme and other financial incentives are expected to mitigate this challenge, making BESS more accessible to a wider range of businesses.

Furthermore, the lack of a robust domestic manufacturing ecosystem for BESS and its components is another challenge that needs to be addressed. Currently, India is heavily reliant on imports from countries like China for its energy storage needs. To reduce this dependence and ensure the long-term sustainability of the BESS market in India, there is a need to develop a strong domestic manufacturing base for energy storage systems and their components.

The Road Ahead: A Vision for the Future

The future of BESS in India looks promising, with significant growth expected in the coming years.
