Use more solar electricity
Store surplus daytime generation and use it after the panels are producing less.
Battery Storage
We examine load shape, solar generation, tariffs, peak demand and resilience requirements before assessing whether storage makes commercial sense.

NUA Energy makes the current position clear, tests the credible options and supports the agreed route. The recommendation is based on how the organisation and site actually operate.
Problems this addresses
Batteries proposed without interval data
Oversizing against a simple annual figure
Confusion between bill saving and resilience
No plan for controls or monitoring
How NUA approaches it
Where storage can add value
Battery storage can capture surplus solar, reduce grid imports during more expensive periods and help manage short demand peaks. It is not automatically worthwhile for every organisation.
We review half-hourly consumption, peaks, tariff structure, solar generation, exports and future requirements before recommending capacity, power and an operating strategy.
Store surplus daytime generation and use it after the panels are producing less.
Charge in lower-cost periods and discharge when prices are higher where the tariff supports it.
Use stored electricity during short peaks to ease pressure on the connection and potentially reduce applicable demand costs.
Keep generation on-site where later use is more valuable than immediate export.
Help manage additional demand from vehicles, heating, machinery or longer hours.
Backup is possible only where the system, isolation, controls and selected circuits are specifically designed for it.
Sizing and controls
Battery capacity is measured in kilowatt-hours and charge or discharge power in kilowatts. Oversizing either can add cost without producing more savings.
We model charging and discharging across a typical day, including solar, grid imports, exports, peaks and tariffs. Location, electrical infrastructure, network restrictions, fire safety and future demand are also considered.
Use half-hourly consumption and demand data rather than an annual total.
Test when the battery can charge, discharge and create value.
Select battery, inverter and control systems for the required use case.
Coordinate DNO approval, installation, safety requirements and ongoing performance review.
How it works
The detail changes by service; the discipline and transparency do not.
What a good process delivers
The relevant costs, assumptions and responsibilities stay visible, and your team retains control of the final choice.
The commercial assumptions are tested before the decision.
The relevant costs and responsibilities are made visible.
The route is shaped around the organisation rather than a standard package.
The next review point remains clear after delivery.
Questions about battery storage
The supplier, lender, funder or technical terms that apply to a live requirement are always checked before a final decision.
Storage is most likely to add value where there is surplus solar, regular demand peaks, time-based pricing or a defined resilience need. Actual consumption data should be assessed first.
Savings depend on charging and discharging times, prices, efficiency and how often useful capacity can be cycled. We model these factors rather than using a standard percentage.
Yes. A standalone battery can charge from the grid in lower-cost periods and discharge when prices or demand are higher, subject to tariff, losses and network arrangements.
Only if it is specifically designed for backup, with suitable isolation, controls and circuits. The required size depends on what must run and for how long.
