Grid stability at scale.
Frequency regulation, voltage support, and renewable smoothing — designed for IPPs, utilities, and grid operators managing India’s fast-growing renewable capacity.

Every megawatt of solar added to the grid is a megawatt that peaks at noon and disappears at dusk. Without storage, the grid has to balance that variability through expensive, fast-response fossil capacity — or accept instability.
Solar generation ramps up fast in the morning and ramps down fast in the evening. Without storage, the grid has to absorb that rate of change through spinning reserves and demand curtailment — both expensive and limited.
±50%India’s grid frequency target is 50Hz. Deviations above and below cause equipment damage, protection trips, and cascading failures. Battery storage is the fastest-responding tool available for frequency regulation.
49.9–50.1 HzPeak demand in India is 6–10pm — after solar has stopped generating. Without storage, utilities have to fire up thermal capacity that sat idle all day to cover a 4-hour peak window. That is the most expensive electricity on the grid.
6–10 PMNot theoretical — these are the applications running on Unity Ultima systems deployed across Rajasthan and Maharashtra.
"The ramp-rate compliance reports have not flagged a single violation since commissioning. Before the storage, we were getting penalty notices every quarter."
O&M Manager · 50MW solar plant with Unity Ultima storage · Rajasthan · Year 1The Unity Ultima is the only Unity ESS product designed specifically for utility-scale grid applications — containerised, C4 rated, with a fully integrated PCS-BMS-EMS stack in a single 20ft unit.
