Battery Energy Storage Systems (BESS)

Firm, dispatchable renewable power — solar and wind paired with grid-scale and C&I battery storage.

Alpha Devraj Renewable Energy LLP provides battery energy storage system (BESS) solutions that store solar and wind power and deliver it when it is needed most. As India’s grid moves toward round-the-clock renewable power, BESS is the technology that turns variable generation into firm, dispatchable electricity.

What is a Battery Energy Storage System?

A battery energy storage system stores electricity — typically in lithium-ion battery packs — and releases it on demand. Paired with a solar plant or wind-solar hybrid project, a BESS charges during hours of surplus generation and discharges during evening peaks, cloudy periods or grid outages. A complete system comprises battery racks, a power conversion system (PCS), an energy management system (EMS) and safety and thermal-management infrastructure.

Our BESS Services

Why pair BESS with renewables?

Solar generates only in daylight and wind varies by season. Storage bridges the gap: it shifts surplus midday solar into the evening peak, smooths short-term variability, provides backup during outages and helps industrial consumers maximise renewable consumption instead of exporting surplus at low tariffs. For utilities, BESS enables firm and dispatchable renewable energy (FDRE) supply.

Why Alpha Devraj

With more than 2.2 GW of renewable capacity delivered across solar, wind and hybrid projects, Alpha Devraj brings proven EPC execution to energy storage. We handle the complete project: feasibility, engineering, procurement, construction, commissioning and long-term operations & maintenance.

Frequently Asked Questions

What is a battery energy storage system (BESS)?

A BESS stores electricity — usually in lithium-ion batteries — and releases it on demand. A complete system includes battery racks, a power conversion system (PCS), an energy management system (EMS) and thermal/safety infrastructure. Paired with solar or wind, it turns variable renewable generation into firm, dispatchable power.

Why add battery storage to a solar plant?

Storage shifts surplus midday solar generation to evening peak hours, smooths variability, provides backup during outages, and helps maximise self-consumption of renewable power instead of exporting surplus at low tariffs.

How long do BESS batteries last?

Lithium-ion BESS installations are typically designed for 10–15 years of operation, depending on cycling depth and frequency, with capacity augmentation possible during the project life. Solar plants they pair with typically run 25 years.

What applications does BESS serve for industry?

Peak shaving, demand-charge reduction, backup power, power-quality improvement, and increasing the share of renewable energy a facility can consume on-site.

Does Alpha Devraj build solar-plus-storage projects?

Yes. Alpha Devraj provides feasibility studies, sizing, EPC and O&M for battery energy storage co-located with solar and wind-solar hybrid plants, as well as behind-the-meter storage for commercial and industrial consumers.
