Battery storage for mine sites: less diesel, fewer engine hours
Fewer engines running, fewer litres burned, and the tonnes counted for Safeguard.
Off-grid mine power stations often run more engines than the load needs, because spinning reserve has to cover the loss of a unit. A battery can carry part of that reserve and absorb load steps, so fewer engines run at better loading. Add solar, and the battery carries daytime energy into the night shift.

Light vehicle and equipment charging
What we model: connection size, charging schedule
Safeguard facilities
A site that emits 100,000 tonnes CO2-e or more of scope 1 emissions a year is a Safeguard facility, and its baseline falls 4.9% a year to 2030. Diesel you don't burn is scope 1 you don't report. We put the tonnes next to the dollars in every mining study.
Engines-off operation
Running with every engine off needs grid-forming inverters and controls that work with your power station. We confirm both for your site in the feasibility study, before any hardware is ordered.

Mining FAQs
How much diesel can a battery save at a mine site?
It depends on the load profile, the generator fleet, the spinning reserve policy and whether solar is added. We model litres and engine hours from your own data in the feasibility study.
Can a battery replace spinning reserve?
It can carry part or all of it, depending on your reliability requirements and the control system. We work through the reserve policy with your electrical team.
Will the system handle heat and dust?
Our containerised systems are rated to operate from -25 °C to +55 °C. They are liquid cooled and housed in IP55 enclosures.
Does displacing diesel help with the Safeguard Mechanism?
Yes. Diesel burned on site is scope 1, so every litre displaced lowers reported emissions. We include the tonnes in the study.
Can the battery move when the mine plan changes?
Containerised systems can be relocated. We plan for it in the design.
How are large projects paid for?
In stages, with milestone payments tied to factory release, shipment and commissioning.
