Your site, your priorities
Establish the case before selecting the equipment.
Commercial sites have different reasons for considering battery storage: using more of their solar generation, managing short peaks in demand, improving resilience or reducing generator running hours.
SES reviews the operating pattern, existing equipment and supply constraints to establish what a system could usefully achieve. Recommendations are based on the site and its priorities, with assumptions and limitations made clear.
The design decisions
Where storage and hybrid power may help.
The benefits depend on when energy is generated, when it is needed and how the system can be operated.
Manage energy costs
Compare charging and discharge opportunities against tariffs, storage losses and expected battery use. Any savings assessment should state its assumptions and operating conditions.
Support peaks in demand
Assess whether controlled battery discharge can help cover short periods of high demand within the available import limit. Storage does not increase the site’s agreed grid capacity.
Improve generator operation
Consider a battery and inverter system that supplies suitable loads between generator runs. The scope to reduce running hours and fuel use depends on the duty cycle and charging strategy.
Feasibility and evidence
Start with how the site uses energy.
Half-hourly consumption data is useful where available, alongside bills, tariffs, solar generation and supply information. If that data is missing, we can review the available records and identify whether temporary monitoring is needed.
The assessment should also consider installation space, access, maintenance and future loads. A useful recommendation explains both the technical arrangement and the assumptions behind the commercial case.
What SES delivers
Bring the whole installation into the design.
Explore independent design and consultancyFeasibility and specification
Review demand, existing generation and supply limits. Define a proportionate system and identify the information, permissions and site work needed to progress it.
Electrical integration
Coordinate the battery system with three-phase distribution, generators, controls and protection as appropriate. Grid-connection requirements and any backup function are considered in the project scope.
Commissioning and handover
Test the intended operating modes, configure monitoring and controls, and provide the agreed documentation. Define how performance will be reviewed against the design assumptions.
Practical answers
Before you decide.
Every site is different. These are useful starting points for a conversation about yours.
Does commercial battery storage always pay for itself?
No. The outcome depends on the installation cost, tariff differences, energy flows and how often the battery can be used effectively. We can assess the case before committing to a system; resilience may also have value that is separate from electricity-bill savings.
Can storage avoid a grid-supply upgrade?
It may help where the constraint is a short peak in demand and the system can recharge between those peaks. It will not solve every capacity problem, particularly a sustained energy shortfall. The load profile, control strategy and network requirements need assessment.
Will a commercial battery provide power during an outage?
Only if the system is designed for that purpose. Backup needs suitable equipment, an appropriate changeover arrangement and a defined set of supported loads. Energy-cost management and backup are related but separate requirements.
Can you work alongside our electrical contractor?
Yes. SES can provide an agreed design, review or commissioning-support role alongside another delivery team, or take responsibility for a defined installation package. Interfaces and responsibilities are agreed at the start.
Discuss your project
Let’s assess the opportunity at your site.
An initial discussion can establish which information will be most useful and whether the next step is a feasibility study, site assessment or detailed design.
