Battery Energy Storage Systems (BESS) are the next layer of India’s renewable build-out, turning intermittent solar into a more predictable, dispatchable resource. Aright is designing storage into its development platform from the start, anchored by the 2 GW Girajsar Solar Park in western Rajasthan, so that utility-scale parks and distributed KUSUM sites can support peak shifting, lower curtailment, and future round-the-clock products as policy and economics evolve.
Design provisioned for batteries at Bikaner, Nokh, NkD, Girajsar, and across the 42 MW KUSUM portfolio
BESS discussions under way at the NkD Solar Park, with plans to seek non-solar connectivity
Additional land and connectivity options in place to host modular 2–4 hour systems
Ongoing discussions with global and domestic OEMs and investors to structure early deployments
India’s renewable sector is shifting from pure capacity growth to reliability and grid integration.
Solar and wind generation now exceeds 200 GW, but most output is concentrated in a narrow daytime band. In high generation states this is already leading to curtailment, while evening and night demand is still met largely by conventional power.
The mismatch between when power is produced and when it is needed is beginning to affect project returns and investor confidence.
For investors and offtakers, storage is the bridge—turning variable output into firm, contracted renewable supply.
Move surplus daytime solar into evening peaks
Shift energy into higher-value hours
Increase transmission line utilisation and defer upgrades
Flexibility for park clients to seek connectivity windows that allow batteries to charge during solar hours and discharge when most needed
Additional land has been dentified inside and alongside these parks. This allows solar capacity to be augmented with storage without new land aggregation or complex logistics. The same transmission lines that evacuate solar during the day can transmit battery power to the grid in non-solar hours, once partners obtain the required non solar connectivity approvals from the relevant transmission utility.
KUSUM sites provide a complementary proving ground at smaller scale. Over time, storage at rural 11 kV substations can smooth agricultural load, cut local curtailment, and improve reliability as economics permit deployment.
Use cases
At parks such as NkD, Nokh, and Girajsar, storage is added alongside existing or new solar capacity, sharing land and evacuation.
Deliver firm solar power during evening and peak hours
Reduce curtailment when daytime generation is corridor constrained
Enable hybrid and RTC-style products for utilities and large C&I consumers
At 11/33 kV rural nodes, building on Aright’s PM-KUSUM footprint, distributed storage links directly to local load.
Stabilise voltage and supply for agricultural and village loads
Ease stress on upstream lines during irrigation peaks
Provide a scalable template for state utilities at the distribution level
Subject to policy, Aright’s land position and grid work in western Rajasthan, including the 2 GW Girajsar platform, can support standalone storage nodes near major substations.
Storage hubs near ISTS substations that absorb excess solar and release during evening peaks
Portfolio-wide optimisation across multiple parks and offtakers
The first wave of storage projects on Aright’s platform will be developed with a mix of technology, utility, and capital partners.
Batteries added alongside existing or new solar capacity at sites such as NkD and Girajsar, sharing land and evacuation
Aright contributes land, grid access, and local execution; partners bring hardware, optimisation, and capital
Distributed systems at rural substations, leveraging existing KUSUM platforms
By embedding storage into every stage of its development framework, Aright is aligning with India’s shift toward firm, dependable renewable power.
