Discover commercial energy storage

Cost effective energy storage has arrived! Your business can:

  • store electricity from solar panels for later use on site;
  • reduce peak electricity costs by avoiding 'time-of-use' surcharges such as TRIAD charges (TNUoS) and DUoS;
  • earn income from support services like firm frequency regulation and capacity market payments to the National Grid;
  • install a reliable commercial UPS battery backup (replacing diesel generators);
  • avoid costly grid upgrades e.g. to support EV charger rollout.

The typical payback time for a commercial battery storage system is around 5 years, with IRR% over 15 years running at 5% - 20%.
