Energy Storage System

Energy Storage Systems (ESS)

There has always been a demand of ‘energy storage systems’ that can store energy efficiently. Over 170 grid scale energy storage technologies are either commercially accessible or are under progress globally. The energy storage technologies landscape varies across numerous systems to ensure we meet our daily energy needs.

To deliver 175 GW of renewables by 2022 and 24×7 power for all by 2019 is the ambitious plan of The Government of India. Furthermore, India in COP 21 has committed to generate 40 per cent power from clean energy sources by 2032.

Indian Market Trend

In 2018, India’s total energy storage market from stationary applications was around 24 GWh. The cumulative potential of energy storage during 2019-2025 is estimated to be between 270 to 365 GWh on a business-as-usual (BAU) and best-case scenario (BCS) respectively. Demand for energy storage in Behind the Meter (BTM) applications will account for ~70 per cent of the cumulative market during 2018-2026.

The projection of Energy Storage Systems (ESS) in India for behind the meter (BTM) sector is 22 GWh during the period 2018-2026 on the base case scenario. The inverter battery market was the largest contributor towards the BTM market installations in 2018, and continues to be so till 2026. Telecom sector contributed nearly 24% towards the BTM market in 2018. The rural electrification sector majorly constitutes the solar home lighting systems under Saubhagya scheme, solar street lights under AJAY scheme, and microgrids. 2018 market was driven by Saubhagya SHLS deployment; however, the sector looks unattractive due to lack of policies existing in the market to drive it beyond 2020.

Government Support

India has signed a Memorandum of Understanding (MoU) with Bolivia for development & industrial use of lithium (Li)—a prime component used in batteries. They recently launched the National Mission for Transformative Mobility with Phased Manufacturing Program for li-ion battery manufacturing by NITI Aayog. Ministry of Heavy Industries has launched FAME -2 (Faster Adoption and Manufacturing of Electric Vehicles) incentives with a budget of Rs 10,000 crore.


It is recommended that minimum capacity for a Li-Ion cell manufacturing be 1 GWH production per year, due to global competition and economies of scale. As per approximations, for cell manufacturing, 1 GWh capacity would require an investment of up to $300 million. Looking at the potential, India has to create a 10 GWh capacity by 2020, India could attract investments to the tune of $3 billion with in next 3-4 years. And as this happens, ancillary development including module development, containers, transformers, inverters could need an equal amount of investment, taking the total potential to $6 billion. With appropriate government support, industry participation, India will be one of the top markets for energy storage adoption and manufacturing.

Energiaa’s ESS is the combination of Energiaa’s cutting- edge, highly efficient Hybrid inverter technology along with an energy pack of upto 72 KWhr of Li Ion battery. Powered with micro-electronics, this grid synchronised plus storage based solar inverter promises 100% utilization of power. Available from 3KVA upto 250 KVA now you can store the electricity according to the time of day and export to grid during lean load periods or when you are not at home.
