How to use this free Renewable Energy Transition Calculator

Estimate avoided diesel as annual solar kilowatt-hours multiplied by an editable litres-per-kWh displacement assumption. Cap displacement at entered annual diesel use, then estimate fuel savings, avoided emissions and simple payback.

Who this helps

Mine operators, industrial energy teams, engineers and project sponsors.

Example application

Screen a solar proposal’s sensitivity to diesel prices and generation output before requesting an engineering design and bankable financial model..

Limits and interpretation

The output is a practical starting point, not a verified professional assessment. Confirm the facts, jurisdiction, assumptions and intended purpose before using any result for a consequential decision.

Frequently asked questions

Does the calculation model batteries?

No. The current screening model treats annual solar generation as the usable energy input. Engineer battery losses, curtailment and dispatch separately.

Are the results investment advice?

No. Simple payback omits finance costs, taxes, maintenance, degradation and reliability requirements.

Why is avoided diesel capped?

A project cannot displace more of the existing diesel use than was entered in this scenario.
