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 can stack several revenue streams, depending on system size and market access.
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
Energy arbitrage, frequency response, capacity-market payments and balancing services — stacked by one smart controller where system size and market access allow.
Grid upgrade often 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 — capacity can be maintained through augmentation.
Integrated AC block
Battery, cooling and power conversion 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 with the appropriate switchgear and controls
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 greater energy 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 | Shift midday solar into the evening peak, when grid power costs most. |
| Back-up & resilience | Keep critical loads running through grid outages. |
