How to use the generator offset calculator

Use the calculator to compare generator fuel use with a battery-supported operating profile. Enter the fuel and runtime information requested by the tool, then review the modeled offset and system sizing outputs.

Results depend on generator loading, fuel consumption, duty cycle, battery efficiency, recharge availability and operating limits. Treat the estimate as a screening tool until assumptions are checked against site records.

Keep your fuel logs and generator specifications available for the next discussion. Contact BX engineers to review a generator replacement or hybrid design.

Project information to bring to the next step

When reviewing a system, separate the outcome from the equipment list. A battery may be asked to deliver a short, high-power response, several hours of backup or a daily charge and discharge cycle. Those duties affect the usable energy, inverter rating, reserve state of charge and expected operating schedule.

Site conditions matter as well. Confirm the electrical service, available installation area, access for delivery, ambient temperature and the control signals the system must exchange with existing equipment. Include safety, maintenance and commissioning responsibilities in the project scope.

Good project information makes the next conversation more productive. Keep the source of each number, note assumptions that still need checking and identify the person who can provide missing records. BX can then outline the next engineering step without treating a generic example as a promise.

Supporting technical resources

For independent technical background, see the U.S. Department of Energy’s energy storage research and resources. Use that reference alongside your site data when reviewing system choices.
