ENERGY & ECONOMICS

Put a battery
through its paces.

Explore how your tariff, site demand and battery assumptions affect energy-shifting savings. The calculation runs in your browser.

Your site. Your assumptions.

ILLUSTRATIVE STARTING VALUES

Try a scenario

01 Battery & demand

Usable AC output

kWh

Energy delivered per full cycle, before annual degradation.Charge / discharge power

Assumed continuous AC rating in both directions.Demand in the peak window

Average net demand available to displace.Round-trip efficiency

AC electricity out ÷ AC electricity in.

02 Tariff & operation

Peak import tariff

p/kWh

Rate avoided when the battery supplies your load.Charging tariff

p/kWh

Grid electricity used to charge the battery.Peak window

hours

Available discharge time per operating day.Charging window

hours

Available charging time per operating day.Operating days

/ year

Days with the entered demand and tariff opportunity.Annual capacity reduction

Scenario assumption, not a warranty prediction.

03 Project costs

Total installed cost

Include your equipment, installation and connection scope.Annual operating cost

£ / year

Include maintenance and software costs you expect.

Use consistent prices and tax treatment. Presets are examples, not quotations or market averages.

Bars show annual net energy savings. Ten-year total above deducts the initial cost. Capacity reduces by your assumption.

ARCGRID AI OPTIMISATION

Could AI optimisation improve your returns?

This estimate uses a fixed tariff-shifting schedule. Arcgrid combines forecasts of site demand and generation with rolling optimisation to adapt battery operation as conditions change.

Additional benefits depend on your site, assets and tariffs and are not included in this estimate.

Excludes financing, tax, replacements, export and flexibility revenue, demand-charge savings and avoided network upgrades. Simple payback uses year-one savings.

READ THE RESULT IN CONTEXT

Useful screening.
A starting point for design.

The model assumes the same demand and tariff windows on each entered operating day. It does not simulate interval data or account for every site constraint. Before committing, ask for a site-specific assessment using your actual data and connection agreement.
