Remote industrial power

At off-grid and weak-grid sites, the cost of power is set by fuel logistics, generator hours and access windows rather than by tariffs. Energy storage integrated with existing generation changes how the system is operated. This page covers the drivers, the architecture and how projects are delivered at remote Canadian sites.

Drivers

What makes storage worth considering off-grid

The economics of remote power are different from grid-connected sites. These are the factors that usually determine whether energy storage belongs in the system.

01Generator loading and runtimeOff-grid sites frequently run generator sets well below their efficient loading for long periods. Storage allows a generator to run at a sensible load point and then shut down, rather than idling against a light overnight load.
02Fuel logisticsAt fly-in, barge-served or winter-road sites, delivered fuel cost is dominated by transport, not commodity price. Reducing generator hours changes the logistics plan, not only the fuel bill.
03Spinning reserve and step loadsStarting large motors on an isolated system usually requires additional generation online. A conversion system with storage can supply the transient, which changes how much generation must run continuously.
04Renewable integrationWhere solar is installed at a remote site, storage is what makes the output usable: it absorbs variability and decouples generation from the site's load profile.
05Camp and process separationCamp load, communications and monitoring, and process load have different criticality. Distribution and storage can be arranged so that essential loads ride through events that the full site would not.
06Deployment and mobilitySome sites are temporary. Containerized and mobile hybrid units are chosen where equipment must be mobilized, relocated at the end of a program, or installed without permanent civil works.

How a remote power project is executed

Remote work is constrained by access before it is constrained by equipment. The sequence below reflects how these projects are planned in practice.

  1. STEP 01

    Site and load definition

    Existing generation, load inventory, seasonal variation, criticality of each load and how the site is accessed through the year.

  2. STEP 02

    Energy architecture

    How generation, storage and any renewable input are arranged, and what the control philosophy is between them.

  3. STEP 03

    Equipment selection

    Containerized, cabinet or mobile hybrid format, chosen against footprint, transport route, ambient conditions and permanence of the installation.

  4. STEP 04

    Logistics planning

    Transport route, lifting requirements, seasonal access windows and staging — usually the binding constraint on the schedule at remote sites.

  5. STEP 05

    Installation and commissioning

    Mechanical placement, electrical connection, control integration and functional testing, with licensed trade work performed by qualified contractors.

  6. STEP 06

    Monitoring and support

    Remote monitoring where connectivity permits, plus a defined technical support path for a site that cannot be reached quickly.

Terminology

Terms used in remote power systems

01
Off-grid / islanded
A site with no utility connection, where all power is generated on site.
02
Weak grid
A site with a utility connection of limited capacity or reliability, often still requiring on-site generation.
03
Hybrid power system
Generation, storage and in some cases renewable input operating under a shared control scheme.
04
Spinning reserve
Generation capacity kept online to absorb load steps and faults; storage can reduce how much must run.
05
Black start
Restoring an isolated system from a de-energized state without an external supply.
