Energy storage systems for businesses
Storage lets you manage electricity consumption at the right points in time — in line with your tariff structure and demand profile.
An energy storage system stores electricity and discharges it at pre-set times. In commercial and industrial buildings it is used mainly to manage consumption and demand.
We assess suitability, the commercial case and the technical and regulatory aspects — before moving to detailed design.
What a storage system does
A battery storage system charges from the grid, from a solar system, or from both, and discharges at pre-set times. It does not generate electricity — it moves it in time.
For businesses, the main use is managing consumption: charging when electricity costs are low and discharging when they are high, in line with the tariff that applies and the infrastructure limits on site.
Optimising electricity consumption
The system is programmed around the site consumption profile: when demand is high, when peak is measured, and which loads can be shifted in time without affecting operations.
That data forms a charging and discharging strategy aimed at reducing the total cost of electricity. It is a management tool built on actual consumption patterns — not on general assumptions.
Managing peak demand
One of the main uses of commercial storage is reducing demand at peak hours. Instead of drawing full power from the grid while the tariff is high, the system meets part of the demand from the batteries.
The achievable reduction depends on the configured capacity, the demand profile and the infrastructure limits on site. That extent is examined as part of the feasibility check.
Combining with a solar system
Storage can be combined with an existing solar system, or with one planned for installation. Surplus generation charges the batteries and is used at times when there is no generation.
In such a combination, a larger share of generation is used on site instead of flowing to the grid, subject to the regulation and route that apply to the project.
Commercial and operational considerations
Storage viability is assessed against the tariff structure, the demand profile, the investment cost and system lifetime. Where the gap between peak and off-peak tariffs is narrow, viability may not be sufficient.
Before proceeding we therefore set out the assumptions and the data behind the estimate — so the decision rests on figures rather than assumptions.
Technical and regulatory fit
Technical fit is assessed against the site electricity infrastructure: connection capacity, distribution boards, existing systems and physical space for the system.
Regulatory and safety aspects are examined in parallel — including fire safety, ventilation and safety requirements — with the competent authorities and in line with the project conditions.
