Energy Capacity

The battery energy system integrates two units into a virtual block to boost efficiency. It provides peak shaving, stabilises the power supply and manages consumption beyond grid limits. It stores excess PV energy to avoid grid exports and uses time-shifting to optimise storage, and enables price arbitrage by discharging during favourable market rates. Future plans focus on reducing the CO₂ footprint in line with sustainability goals.
