Store more. Pay less.Around the clock.
Commercial battery storage cuts peak demand charges, unlocks time-of-use savings and keeps your business running if the grid goes down.

Your grid connection costs you more than you think.
Battery storage attacks your bill from multiple angles simultaneously — not just one.
Peak demand shaving
Reduce your maximum demand reading by discharging battery during peak usage periods. This directly cuts your standing charges and capacity fees — often the biggest hidden cost on commercial bills.
Time-of-use optimisation
Charge during cheap overnight rates (Octopus Flux, Agile, Economy 7). Discharge during expensive peak periods. The battery pays for itself through tariff arbitrage alone on many sites.
Grid outage protection
When the grid drops, your battery keeps critical loads running. Servers, refrigeration, security systems and emergency lighting can all be backed up depending on system size.
Solar maximisation
Stop selling solar at cheap export rates. Store excess generation and use it during your evening and peak periods instead. Battery + solar unlocks the full value of your roof.
Smart tariff integration
Fully compatible with dynamic tariffs including Octopus Agile, Intelligent Octopus and time-of-use business tariffs. Smart scheduling runs automatically based on real-time pricing.
DNO constraint management
Some grid connections have export limits that prevent solar from performing at full output. Battery storage manages export constraints and ensures you never waste generation.

Commercial solar
Don’t want to use capital? You don’t have to.
Commercial battery storage is available on flexible finance terms, typically 3–10 years. Monthly repayments are often lower than the monthly savings from the system — meaning the battery pays for itself from month one.
For eligible sites, a Power Purchase Agreement (PPA) structure is also available — ideal if you want zero capital outlay and a fixed per-unit electricity rate.
