Battery Energy Storage Systems
Store clean power. Release it when it matters.
Alpha Devraj ESS builds containerised LFP battery storage and delivers solar, wind + BESS solutions — from a single cabinet to grid scale, across India.
The thesis
Store the midday sun. Serve the evening peak.
Every system we build runs one economic idea: charge when energy is cheap and abundant, discharge when it is scarce and expensive. This is a day in that life.
Product
One platform. Three form factors.
The same LFP battery technology, packaged for wherever it needs to run. Switch between configurations to see how it scales.
C&I Cabinet
Compact and outdoor-rated. Storage that fits beside the factory, not a substation.
- Capacity
- 100–260 kWh
- Footprint
- ~1.3 m²
- Cooling
- Liquid / air
- Ingress rating
- Outdoor IP55
Best for: Demand charges, backup and behind-the-meter savings at commercial and industrial sites.

Solutions — by configuration
Generation and storage, engineered together.
From a standalone battery working the tariff to full hybrid plants — storage engineered with whatever generates beside it.
Standalone BESS
A battery, the grid, and the tariff — the purest form of storage economics.
ExploreSolar + BESS
Store midday solar and dispatch it into evening peaks and high-tariff windows.
ExploreWind + BESS
Firm variable wind output into schedulable, dispatchable power.
ExploreSolar + Wind + BESS
Solar by day, wind by night, battery in between — near round-the-clock renewable power.
ExploreSolutions — by use case
What the battery actually does.
The same box earns its return in different ways. These are the jobs we design for.
Peak Shaving
Discharge into demand peaks and cut the demand-charge line on your bill.
Microgrids
Self-contained power for campuses and critical sites — grid-connected or islanded.
Renewable Firming
Turn variable solar and wind into firm, contracted, schedulable supply.
Grid Stabilization
Millisecond-class response for frequency regulation, reserves and ramping support.
Backed by Alpha Devraj Renewable Energy
Built by a developer that runs its own plants.
Our parent company develops, finances and operates solar and wind projects in Gujarat. Alpha Devraj ESS systems are engineered by the same team — and prove themselves on our own plants before they carry anyone else's.
That lineage shows up where it matters: systems sized by people who model tariffs for a living, DPRs and financial models that lenders accept, and hardware we are willing to operate for twenty-five years.

FAQs
The questions we get asked.
How do I know what size storage my facility needs?
We start with a load study — your consumption profile, tariff structure and peak demand. From there we size solar and battery together and model the payback before anyone commits. You get the numbers first, the hardware second.
Which battery chemistry do you use?
LFP (lithium iron phosphate) is our default for most C&I and grid work — it is safe, long-cycling and cost-effective. For long-duration, high-throughput grid roles we also evaluate vanadium redox flow (VRFB). The recommendation follows the project economics, not a preferred vendor.
What kind of payback period is typical?
It depends entirely on your tariff, demand charges and solar availability — which is exactly why we model it per site rather than quoting a generic figure. The savings come from peak shaving and Time-of-Day arbitrage; our feasibility model shows you the specific numbers for your facility.
Can storage work with my existing solar plant?
Yes. We retrofit storage onto existing solar as well as designing new hybrid solar+wind+BESS systems from scratch. Adding storage lets you self-consume more of your generation and shift it into high-value windows.
Do you handle tenders, DPRs and financial models?
Yes — feasibility, DPR, TEV-ready financial modelling and full bid support are core to what we do, backed by the project-finance discipline of our parent, Alpha Devraj Renewable Energy.
Air-cooled or liquid-cooled — what do you deploy?
Our standard containers are liquid-cooled, which gives tighter thermal control, higher energy density and longer cell life. Smaller C&I cabinets can be air or liquid cooled depending on duty cycle and site conditions.
What about warranty and long-term operation?
We provide long-term O&M, remote monitoring and performance management, with capacity augmentation planned into the design so the asset holds its rating over its life. Warranty terms are set per project and chemistry.
