Mining

Hybrid solar-storage-diesel systems for remote mining operations.

Problem

Why this matters.

Mining sites burn expensive diesel and need clean continuous power. Hybrid storage cuts fuel and improves resilience.

Remote hard-rock and open-pit mines run 24/7 on diesel microgrids: crushers, ball mills, ventilation fans, and dewatering pumps form a heavy continuous base, punctuated by severe motor inrush. Delivered diesel — with its logistics premium at altitude and distance — is the single largest controllable operating cost, and N+1 gensets burn fuel idling as spinning reserve. A grid-forming battery lets gensets run at a proper 75–85% load factor instead of oversized-and-underloaded; solar at high-DNI sites (Atacama-class copper regions, the Brazilian interior) displaces daytime burn.

Architecture

How the system fits together.

PV, battery, and the existing diesel plant share an off-grid bus under one controller. The battery grid-forms, PV serves the day, and generators dispatch as reserve at proper load factor instead of idling as spinning reserve.

FAQ

Common questions.

How much diesel can a hybrid actually displace?

Solar-heavy hybrids typically displace daytime burn and cut generator idle hours; the audited number comes from your generator logs and PV potential, not a rule of thumb.

What happens when a crusher starts and PV dips at once?

The battery absorbs the inrush and the transient; generators only start if the sustained load requires it. That is the point of a grid-forming battery.

How is service handled at a remote site?

Remote monitoring through Navvion APM plus a field-service contract with defined response — spare strategy is designed around your logistics constraints.
