Key Highlights
- 3.37 GWh of battery capacity installed at Khavda, Gujarat – the biggest single‑site storage plant outside China.
- Construction completed in ten months, with 1.37 GWh added in March 2026, marking one of the fastest utility‑scale roll‑outs worldwide.
- Projected to supply electricity for roughly ten‑million households for a full day and to support peak‑load cities such as Indore and Chandigarh.
- Forms a cornerstone of Adani Green’s 30 GW renewable agenda, which aims for 9.9 GW already operational and a target of 30 GW by 2029.
- Future roadmap includes >10 GWh by FY27 and 50 GWh within five years, positioning storage as the backbone of India’s clean‑energy transition.
Detailed Insights
The Khavda Battery Energy Storage System (BESS) integrates 3.37 GWh of lithium‑ion modules to capture surplus generation from the adjacent solar‑wind complex and discharge it during periods of high demand. By buffering intermittent output, the BESS stabilises grid frequency, augments peak‑hour supply, and enhances the overall reliability of renewable sources. The deployment was achieved in a compressed ten‑month window, a timeline that rivals the fastest global utility‑scale roll‑outs.
Operational flexibility enables the facility to illuminate roughly 1.2 crore LED lamps for ten hours, power nearly ten lakh homes for a day, or provide emergency support to an entire state such as Goa. These capabilities underscore the strategic role of large‑scale storage in mitigating the intermittency inherent to solar and wind power.
Khavda sits within Adani Green’s expansive renewable complex, covering 538 km² and slated to reach a cumulative capacity of 30 GW by 2029. The storage installation not only fortifies this renewable ecosystem but also serves as a template for subsequent projects across India.
Key Concepts
- Battery Energy Storage System (BESS): A collection of rechargeable batteries that absorb excess electricity when generation exceeds demand and release it when the grid requires additional power.
- Intermittency: The fluctuating nature of renewable generation caused by variable weather conditions and diurnal cycles.
- Grid Stability: The ability of an electricity network to maintain consistent voltage and frequency despite changes in supply or demand.
- Peak‑Load Support: Supplying additional electricity during times of highest consumption, typically evening hours or extreme weather events.
- Utility‑Scale Storage: Large‑capacity battery installations (usually measured in gigawatt‑hours) designed to serve regional power grids rather than individual consumers.
