Free calculators

Size the opportunity yourself.

Free calculators with assumptions you can edit. No sign-in needed. They run on SPARKO TERMINAL.

Two calculators: trading opportunity and energy value. Switch between them inside the calculator.

Results depend on the assumptions you enter. Your contract and your tariff decide the real numbers.
