Buy low. Use high.
Every single day.
Battery storage is the intelligence layer of your energy system — storing cheap or self-generated power and releasing it exactly when it's worth most.
Four revenue streams in one asset
Electricity isn't one price — it swings dramatically within a single day. Batteries exploit that: charging on cheap overnight rates or free solar, then discharging through the expensive peaks. That alone reshapes your bill.
Add resilience (ride through outages), maximised solar self-consumption, and paid grid-balancing services, and commercial storage becomes one of the hardest-working assets on your site. River models all four value streams against your half-hourly data before recommending a system.
- Half-hourly data modelling shows the true value before you invest
- Peak shaving cuts your most expensive units and demand charges
- Seamless pairing with new or existing solar arrays
- Grid service participation (frequency response, DFS) managed for you
Commercial benefits of onsite storage
Electricity isn't one price — it swings dramatically within a single day. Storage is how you exploit that.
Peak shaving
Discharge through red-band periods and peak pricing — the most expensive electricity you buy. Charging on cheap overnight rates or free solar and discharging through the expensive peaks reshapes your bill without changing anything about how you operate.
Solar maximiser
Stop exporting surplus generation for pennies; store it and use it when grid power costs pounds. For sites whose usage peaks outside generation hours, storage is what turns a good solar array into a much better one.
Resilience
Keep critical loads alive through outages — no diesel, no noise, no fuel deliveries and no weekly test run. Resilience stops being a separate capital project and becomes a property of the system you already have.
Grid service income
Participation in paid grid-balancing services such as frequency response and the Demand Flexibility Service, managed on your behalf. It is the fourth value stream from a single asset, and it runs in the background.
Storage installations
Modelled against your half-hourly data, sized to your value streams, installed and optimised as one system.
Containerised
Containerised battery systems
Self-contained outdoor systems for sites without suitable indoor space, sized from your half-hourly consumption data. Modern commercial systems use LFP chemistry with battery management, thermal monitoring and fire suppression as standard.
Plant room
Plant-room systems & integration
Indoor installations integrated into existing plant rooms and distribution, commissioned to work with the electrical infrastructure you already have. Installed to current IET and manufacturer standards throughout.
Solar-paired
Solar-paired storage
Seamless pairing with new or existing solar arrays, so surplus generation is stored rather than exported. Storage also stands on its own — tariff arbitrage and peak shaving work without any solar at all; solar simply adds a free charging source.
Dispatch
Smart dispatch & optimisation
Dispatch software adapts continuously to tariffs, solar yield and grid events, deciding when to charge, hold and discharge. It also manages cycling to protect longevity, so the asset reaches its expected life rather than being worked to death.
Our process
Six stages, starting with your data — because the right battery size is a finding, not an opinion.
Half-hourly data modelling
We analyse your half-hourly consumption data and tariff structure. The right size depends on your load shape, not your instinct — bigger is very often not better, and the data is what tells us so.
Value-stream analysis
All four value streams modelled against your actual data: peak shaving, solar self-consumption, resilience and grid services. You see what each one is worth to you before anyone recommends a system.
Sizing, design & proposal
Battery capacity and power rating optimised for the value streams that actually pay on your site, presented with cost, saving and payback laid out plainly.
Supply & scheduling
Tier-one systems with capacity warranties specified and sourced, with delivery and any craneage or groundworks coordinated around your operation.
Installation & integration
Containerised or plant-room systems installed and fully integrated with your existing electrical infrastructure and any solar generation, to current IET and manufacturer standards.
Commissioning & optimisation
Systems commissioned, dispatch software configured against your tariffs, and performance monitored on an ongoing basis — with dispatch tuned as your tariffs and usage change.
SafeContractor approved and installed to current standards
River holds SafeContractor accreditation for its renewables installation work. Commercial systems use LFP chemistry with battery management, thermal monitoring and fire suppression, installed to current IET and manufacturer standards.
