Electric vehicle manufacturer Ola Electric has launched Ola Shakti, a residential sector-focused battery energy storage system (BESS) in four configurations.

The storage system will come in 1.5 kWh, 3 kWh, 5.2 kWh, and 9.1 kWh configurations.

Ola claims it has a charging time of two hours and a backup capacity of up to one and a half hours.

The energy storage systems are powered by Ola’s indigenous 4680 cell technology and its automotive battery packs.

Ola said the BESS’ modular design allows for multi-directional stacking and easy scalability. Ola Shakti delivers automotive-grade safety and achieves industry efficiency of up to 98%, with zero operational and maintenance costs.

The company said its BESS’ features, including time-of-day charge/discharge scheduling, intelligent backup prioritization, and remote diagnostics, will allow customers to save money.

The features also include over-the-air software updates, expansion capabilities, and online operation mode for continuous energy supply.

Ola Shakthi will provide real-time control over battery states and energy flow to customers.

Ola also claimed that, unlike conventional lead-acid inverters or diesel generators, Shakti features instant 0 ms changeover time and operates across a wide input voltage range of 120 V to 290 V, protecting appliances from voltage fluctuations.

It said the BESS can power air conditioners, refrigerators, induction cookers, farm pumps, and communication equipment.

Forecasting the BESS market to expand to ₹3 trillion (~$34 billion) by 2030, Ola expects the annual consumption for its storage system to scale up to 5 GWh.

The board of directors and the shareholders of Ola Electric Technologies, a wholly owned subsidiary of Ola Electric Mobility, recently approved a proposal to raise ₹8.77 billion (~$98.92 million) by issuing up to 877.64 million shares to Ola Cell Technologies, another subsidiary.

According to the newly released India’s Energy Storage Landscape 1H 2025 Report by Mercom Research, India added 48.4 MWh of energy storage capacity in the first half of 2025. Solar-plus-storage systems accounted for nearly 56% of India’s cumulative installed capacity. Over 12% of the BESS installed were standalone systems.
