Battery Energy Storage
Containerised, liquid-cooled LFP storage that banks low-cost and solar energy and releases it when it is most valuable — cutting demand charges, adding resilience, and unlocking multiple grid revenue streams.
Overview
What is a battery energy storage system?
A BESS stores electricity in lithium-iron-phosphate (LFP) batteries and discharges it on demand. Our preferred solution is a fully integrated, liquid-cooled AC block — battery, cooling and power-conversion built into one 20-ft container — that installs faster and costs less than assembling separate parts. Blocks stack from a few MWh to hundreds of MWh, pair naturally with solar PV and EV charging, and are run by a single energy-management system that stacks several revenue streams at once.
Built for revenue, resilience and safety
5 MWh Per AC block
5,015 kWh of usable energy in a single 20-ft container.
2.5 MW Rated power
Up to 2,500 kW per block; stack to 25 MW and beyond.
20 yr Design life
Long-life LFP with ~80% capacity retained at year 10.
LFP Safe chemistry
Liquid-cooled, with multi-level fire protection built in.
Why battery storage
Several revenue streams at once
Energy arbitrage, frequency response, capacity-market payments and balancing services — all stacked by one smart controller.
Grid upgrade avoided
Shave peak demand so you can add EV chargers, heat pumps and new load without a costly DNO connection upgrade.
Safe, long-life LFP
Liquid cooling and multi-level fire protection, with ~80% capacity retained at year 10 and a 20-year design life.
Integrated AC block
Battery, power conversion and transformer in one container — faster, cheaper installation and a smaller footprint.
Modular & solar-ready
Stack from a few MWh to hundreds of MWh and pair with on-site solar PV and EV charging for a low-carbon site.

Grid-scale & utility
Multi-MWh installations providing arbitrage, balancing and capacity to the wholesale market.
Commercial & industrial
Peak-demand shaving and back-up for factories, data centres and large estates.
Solar-plus-storage
Bank surplus solar generation for use after dark instead of exporting it cheaply.
EV charging support
Buffer high-power DC charging so a site fast-charges without a grid upgrade.
Microgrid & back-up
Keep critical loads running through outages and enable islanded operation.
Frequency & balancing
Sub-second response to grid signals for contracted ancillary-service income.
Storage engineered around your site and your returns
We size and integrate storage to your load profile and revenue goals — not just drop in a box.
Modular containers delivered, installed and commissioned — scalable as needs grow.
Resilient, revenue-generating storage
Lower energy bills, back-up power through outages, and a clear path to a grid-independent, low-carbon site.
How a battery earns and saves
Headline figures for a reference 25 MW / 50 MWh deployment (ten AC blocks), and the revenue and savings a BESS can stack.
| Revenue / saving | How it works |
|---|---|
| Energy arbitrage | Charge when power is cheap or solar is in surplus; discharge at peak price. |
| Balancing & frequency response | Rapid charge/discharge that helps stabilise grid frequency for contracted income. |
| Capacity market | Payments for being available to deliver power at system peaks. |
| Peak-demand shaving | Cut expensive peak-demand and network charges on the site’s electricity bill. |
| Solar self-consumption | Store surplus solar for use after dark rather than exporting it cheaply. |
| Back-up & resilience | Keep critical loads running through grid outages. |
