Commercial battery storage systems to slash peak demand charges, increase resilience, and maximise your solar investment.
Multiple revenue streams from a single investment
Reduce expensive peak demand charges by discharging batteries during high-usage periods. Indicative savings: £20,000–£50,000/year for medium-sized businesses, subject to your tariff and usage profile.
Charge batteries during cheap off-peak hours (Economy 7 or overnight rates) and discharge during expensive peak periods. Arbitrage energy costs.
Maintain critical operations during grid outages with automatic backup power. Protect against lost revenue from downtime and equipment damage.
Store excess solar generation instead of exporting at low rates. Use stored solar energy during evenings and peak periods when generation is zero.
From assessment to live battery storage in 6 steps
We analyse your half-hourly meter data, peak demand patterns, and tariff structure to identify savings opportunities.
Receive detailed battery specification, charge/discharge strategy, ROI projections, and funding options.
We handle all G99 grid connection applications and DNO approvals for battery export/import.
Professional installation by certified engineers. Indoor or outdoor enclosures. Minimal business disruption.
System testing, grid connection, and integration with existing solar/building management systems.
24/7 AI-driven optimisation learns your usage patterns and predicts grid prices for maximum savings.
Simple information to design your optimal battery system
Last 12 months of consumption data to identify peak demand patterns and optimisation opportunities.
Current unit rates, standing charges, and peak demand charges to calculate accurate savings.
Maximum demand (kW) and when peaks occur. We use this to size the battery for optimal peak shaving.
Which loads need backup power during outages and how long backup is required (if applicable).
Don't have this data? No problem. We can request it from your energy supplier.
Triple your savings with an integrated energy system. Solar generates, batteries store, EVs charge—all optimised automatically.

Battery storage isn’t a single product — sizing, chemistry and control logic depend on whether you’re peak-shaving, providing backup, or pairing with solar. Here’s how it plays out by sector.
Overnight depot charging plus peak shaving keeps van fleets running on existing grid capacity — often saving the 6-figure cost of a DNO upgrade. See our UPS London deployment for the playbook.
Avoid Triad charges and DUoS red-band exposure by shifting load. Battery storage also gives a buffer for machinery start-up spikes that would otherwise breach your agreed capacity.
High evening demand from HVAC and lighting often coincides with peak tariff windows. A right-sized battery pays back fastest where peak demand charges drive the bill.
Hotel and venue loads spike at predictable times. Battery storage smooths those spikes and gives back-up cover for events and conference business where a 30-minute outage is unacceptable.
Critical-care islands and refrigerated stores need rock-solid resilience. We pair battery storage with a generator and clear UPS handover logic so clinical workflows are never interrupted.
Battery storage extends UPS runtime, reduces generator wear, and unlocks demand-response revenue when paired with a flexibility aggregator.
From peak-shaving a delivery depot to smoothing a shopping-centre’s load profile — see how clients use battery storage on real sites.
65 vans charged overnight in existing grid capacity — avoiding a ~£200k DNO upgrade — with solar top-ups by day.
120 chargers across customer car parks with contactless/RFID payment, mobile-app availability, and a dedicated staff zone.
Standardised charging across 15 UK hotels, integrated with the property management system so guest charging is one line on the room bill.
