What could a
battery save?
Explore tariff shifting, charging losses, annual costs and a ten-year scenario using your own assumptions.
Open battery calculator 02 / POWER & CAPACITYCan a battery
support your peak?
Compare a site limit with additional load, battery power and event duration. See what the numbers can—and cannot—tell you.
Check modelled headroomLess jargon.
More understanding.
How to size a commercial battery
Understand kW, kWh and the load you can actually shift before choosing a battery.
What actually drives battery savings?
A transparent look at tariff spreads, losses, utilisation and costs that headline paybacks miss.
G99 and G100: different jobs, one site
Understand connection requirements and import/export limitation without treating either as automatic approval.
A useful estimate
shows its working.
Every calculator explains its assumptions, boundaries and omissions. Our guides point to the underlying ENA, network operator and research sources.
This resource is created by Arcgrid, a UK energy management software business. We make that relationship visible, and distinguish illustrative scenarios from measured results.
