Solutions — by configuration
What is a standalone battery energy storage system (BESS)?
A standalone BESS is a battery system connected directly to the grid or your facility, with no co-located generation. It charges when power is cheap or surplus and discharges when it is expensive or scarce — earning through time-of-day arbitrage, demand-charge savings, backup and grid services. Alpha Devraj ESS delivers standalone systems from a single cabinet to grid-scale blocks.
How it works
Watch it run.
Why standalone is the fastest route to storage
No land for panels, no wind study, no generation to build: a standalone BESS drops onto a substation bay or a factory yard and starts working the tariff from day one. For most C&I sites and DISCOM applications it is the shortest path from decision to commissioning — and the easiest asset to expand later.
One asset, several income streams
The same battery stacks value: charge in off-peak windows and discharge into peak tariffs (time-of-day arbitrage), clip your maximum demand (demand-charge reduction), ride through outages (backup), and — at grid scale — sell ancillary services. We model the stack for your tariff and dispatch the battery to capture it automatically.
What we deliver
A complete grid-connected storage plant: LFP battery in cabinet, container or block form, power conversion, protection and metering, and an EMS programmed with your tariff calendar. Delivered, commissioned and monitored 24×7, with augmentation planned into the layout.
Common questions
Does a standalone battery need solar to make sense?
No. If your tariff has a meaningful gap between off-peak and peak rates, or your bill carries heavy demand charges, the battery earns on the tariff alone. Solar can be added later — the BESS is designed to accept it.
How quickly can a standalone system be deployed?
Cabinets and single containers are the fastest systems we deliver: site works are minimal, and the system arrives factory-tested as one unit. Utility-scale blocks take longer for grid connection approvals than for the hardware itself.
