What is a BESS and how does it save money?

A Battery Energy Storage System (BESS) charges from the grid or solar during low-cost periods and discharges during expensive peak times. It also provides backup power and earns revenue from grid services like Frequency Response.

What is the typical payback for commercial battery storage?

For most UK industrial sites, payback is 5–9 years, depending on energy usage patterns and whether you participate in grid services like demand response.

Is battery storage safe for industrial sites?

Yes. Lithium iron phosphate (LFP) chemistry is thermally stable and widely used. Every system is engineered with fire suppression, thermal management, and safety shutdowns.

Can I add a BESS to an existing solar PV system?

Absolutely. A BESS can be retrofitted to an existing solar array, storing excess daytime generation for evening use. This is often the highest-ROI configuration.

Do you handle DNO grid connection and G99 applications?

Yes. We manage the entire grid connection process, including DNO applications, G99 compliance, and export/import metering.

How It Works

Our Delivery Process

A BESS system is engineered around your half-hourly demand data to maximise savings on every tariff component.

Load profile analysis

We analyse 12 months of interval data to identify your peak demand windows, Triad exposure, and DUoS colour bands.

System sizing & design

Optimal capacity (kWh) and power (kW) are modelled to maximise financial return within your grid connection limit.

Installation & commissioning

Modular LFP battery cabinets are installed with a bi-directional inverter and energy management system (EMS) integrated into your site SCADA.

Ongoing optimisation

The EMS dispatches the battery automatically using day-ahead tariff signals, with remote monitoring and performance reporting.

Case Study

Food Distribution Centre, East Midlands

£62k/year saved on peak demand charges

A 1 MWh / 500 kW BESS installed alongside an existing 400 kWp rooftop solar array reduced Triad exposure by 90% and enabled full UPS backup for cold-store critical loads.
