Energy savings calculator
Estimate your energy savings and payback
Model the two levers that move an energy case — tariff/efficiency savings and outage avoidance — and see indicative monthly savings, annual savings, and payback. When you reveal your estimate, the ASE energy desk follows up with a tailored review.
How the estimate works
Two levers, netted against project cost
01
Tariff & efficiency savings
Your monthly consumption × tariff rate is your baseline energy spend. Applying a realistic tariff-savings target (peak shaving, efficiency, on-site generation) estimates the recurring monthly saving.
02
Outage-avoidance value
Outage hours × cost-per-hour is your monthly downtime exposure. Applying an outage-coverage target (storage/backup sized to your critical load) estimates the downtime cost you avoid.
03
Payback
Total monthly savings annualised, netted against an estimated project cost, indicates the payback window. All figures are indicative — the energy desk refines them against your real tariff, load, and outage profile.
Illustrative ranges for sites in ASE’s coverage: tariff savings often model in the 10–25% band and outage coverage in the 50–90% band, with payback frequently in the 24–60 month range. Your figures depend entirely on your own tariff, load, and outage profile — the calculator is indicative, not a quotation.

Beyond the estimate
A tailored review from the energy desk
The calculator gives you an indicative figure in seconds. ASE’s energy desk turns it into a real case — modelling generation, storage, redundancy, and critical-load review against your site. See the full energy practice for context.
