Store energy. Cut costs. Add resilience.
BESS Battery Energy Storage Systems
A Battery Energy Storage System (BESS) helps you store electricity when it’s cheap or surplus, then use it when prices are high or when you need backup. Perfect for businesses with high energy bills, solar PV, EV charging, or reliability requirements.

- ✅ Bill + half-hourly data review
- ✅ Recommended battery size + operating strategy
- ✅ Budget cost + payback range
Why install a BESS?
1) Reduce electricity bills
- Peak shaving: lower your site peak demand and reduce expensive peak-time consumption
- Load shifting: charge when rates are low, discharge when rates are high
- PV self-consumption: store excess solar instead of exporting it cheaply
2) Improve resilience and continuity
- Backup power: keep critical loads running during outages
- UPS-style support: protect sensitive equipment from dips and interruptions (depending on design)
3) Enable smarter EV charging
- Reduce grid constraints and support high-power charging without costly upgrades
- Smooth charger peaks to protect your connection capacity
4) Future-proof your site
- Prepare for time-of-use tariffs, rising grid costs, and electrification
- Increase control over energy and carbon reporting

Frequently asked questions
How big should my BESS be?
Usually based on your peak demand, tariff structure, load profile, and goals (peak shaving vs backup vs PV optimisation). A quick assessment using half-hourly data gives the most accurate answer.
Do I need DNO approval?
Often yes, depending on export capability and how the system connects/operates. We design around your constraints and handle the application route where needed.
What’s the typical payback?
Varies widely by tariff and use case. Peak shaving + time-of-use arbitrage + PV optimisation generally improves returns; backup-only projects are more resilience-driven than ROI-led.
