Battery storage that pays for itself — and then some.
Behind-the-meter battery systems for peak-shaving, load-shifting and flexibility revenue. Cut DUoS red-band charges, defer grid upgrades and turn variable demand into a controllable asset.
- Peak-shave to slash DUoS red-band and capacity charges.
- Stack revenue: triad avoidance, DFS, Capacity Market and Dynamic Containment.
- Solar-coupled or stand-alone, 50kWh to 5MWh — modular and battery-agnostic.
- 10-year performance warranty with active cell-balancing and remote diagnostics.
Why clients choose us for this
We size from your half-hourly data, not nameplate. That means the battery actually clips the peaks that drive your bill — not just the ones in a sales spreadsheet.
Storage shouldn't just save money — it should make it. We integrate with aggregators for Dynamic Containment, DFS and Capacity Market participation, layered on top of behind-the-meter savings.
Need more capacity but the DNO quote is six figures and 18 months out? Storage often unlocks the capacity you need at a fraction of the cost — and without the wait.
Retrofit to existing solar PV, design as part of a new install, or deploy as a stand-alone asset for arbitrage and flexibility. Battery-agnostic — Tesla, Sungrow, BYD, Pixii and more.
Optional islanding mode keeps critical loads running during outages — particularly valuable for care, data and continuous-process sites.
Cloud monitoring with SoC, SoH and revenue dashboards. 24/7 alarm response and a 4-hour critical-fault SLA available across Scotland.

Share your HH data and we'll model peak-shave, flex revenue and payback — typically back within 48 hours.
Frequently asked
What's the payback on commercial batteries?+
6–8 years is typical for peak-shaving + solar-coupled installs. Adding flexibility revenue (DC, DFS) can pull this below 5 years on the right sites.
Do we need solar first?+
No. Stand-alone batteries are viable purely on peak-shaving, capacity charge avoidance and grid-services revenue. Solar-coupling improves the economics but isn't a prerequisite.
Can it provide backup power?+
Yes, with islanding-capable inverters. We can configure critical-load circuits to keep running through outages — particularly important for care, data and continuous-process sites.
Which batteries do you install?+
We're battery-agnostic. Common choices include Tesla Megapack, Sungrow, BYD, Pixii and Alfen — selected based on cycle life, warranty and your revenue strategy.
What about grid charges and DUoS reform?+
DUoS reform actually strengthens the case for storage by widening the spread between peak and off-peak. Our financial models update with each Ofgem change so the business case stays current.
