Utility Scale Storage

For decades, the “energy trilemma” – balancing energy security, affordability, and environmental sustainability – has shaped how nations think about energy strategy. For much of the Global South, it has served as a practical compass. But today, that compass may no longer be sufficient.

India’s ambition to achieve a 60% non-fossil fuel share in its energy mix by 2035 faces a critical financing challenge, with annual investment in renewables, storage, and transmission projected to rise sharply from $68 billion by 2032 to $145 billion by 2035—according to a new report by the Institute for Energy Economics and Financial Analysis (IEEFA).

A new sodium-ion cell for ESS may further improve competitiveness in large-scale systems against the weight of the lithium-ion battery sector.

New modelling by Ember finds that solar paired with battery storage could supply 90% of India’s electricity demand at a levelised cost of electricity (LCOE) of INR 5.06/kWh ($56/MWh).

Indian economy size is likely to surpass $5 trillion by 2030, driven by manufacturing expansion, infrastructure development, and strong economic reforms. However, sustaining that growth requires not just clean energy but also one that is predictable, uninterrupted and dispatchable.

Agratas, the Tata group’s global battery business, has reported progress on its Sanand battery facility in India, with the steel frame now complete. Production is expected to commence in 2027.

EV battery manufacturer Neuron Energy has announced its entry into the grid-scale energy storage segment with plans to commission a fully automated battery energy storage system (BESS) manufacturing facility in Talegaon, Maharashtra. Once fully operational, the facility will have an annual production capacity of 5 GWh, with the capability to manufacture up to 1,000 containerised BESS units per year.

Solarworld has secured a 200 MW balance-of-system (BOS) package for a grid-connected solar PV project in Bikaner, Rajasthan. It has also won EPC contracts for battery energy storage systems totaling 182 MW/364 MWh at thermal power stations operated by NTPC.

Italy’s energy regulator ARERA has approved a proposal from the Ministry of the Environment and Energy Security to target 16 GWh of storage capacity in the 2029 MACSE auction, while urging caution on final volumes to reflect existing pipeline capacity.

Enviro Infra Engineers Ltd (EIEL), an infrastructure company focused on water and wastewater treatment solutions, has entered the battery energy storage system (BESS) segment by securing EPC contracts totaling 930 MWh.
