Applications

There are many applications for battery energy storage. The two most commonplace use cases that BESS can support are EV charging and maximising solar generation.

EV Charging

Providing additional capacity and helping to decarbonise charging.

Can BESS help solve Scope 3 emissions for vehicle manufacturers?

Solar integration

Use renewable energy when it's needed most, or when prices peak.

Faster payback, stronger returns and new revenue opportunities

With reduced system costs and changes in the P415 regulation unlocking new revenue opportunities, investing in energy storage now delivers a stronger business case. A typical site with a 1.2MW solar installation, combined with a 900kW battery energy storage system, could potentially earn:

>£100k

additional annual revenue per MW of installed capacity

5 years

Typical payback period

21%

Potential IRR over a 15 year period

Benefits

Lower energy costs

Battery energy storage delivers an immediate reduction in energy costs while protecting your business from grid price volatility. By managing peak demand, you can significantly reduce capacity charges and take control of your energy spending.

Benefits

Revenue generation

Generate multiple revenue streams through frequency response, arbitrage, peak shaving, and grid services. With P145 regulation opening up significant energy wholesale market opportunities, battery storage becomes an active income source for your business.

Renewable enhancements

Maximise your solar generation and ensure excess green energy is never wasted. By storing surplus renewable energy, you can offset increases in electrical demand and make full use of your on-site generation.

Overcome grid capacity constraints

Increase your available power capacity on-site without the lengthy delays and costs of grid connection upgrades. Battery storage enables business growth that would otherwise be grid-limited.

Lower carbon impact

Achieve a significant reduction in your carbon footprint while contributing to your sustainability targets. Battery energy storage helps you meet environmental commitments without compromising operational performance.
