How the Nunavut system works
Nunavut has no shared transmission grid. Its 25 communities sit across roughly two million square kilometres with no roads or power lines linking them, so each runs on its own stand-alone diesel plant operated by Qulliq Energy Corporation, the territory\'s single Crown utility, serving about 15,500 customers. Diesel for those plants, and the oil that heats nearly every building, arrives by sealift during the short ice-free summer and is stored in community tank farms for the year. There is no competitive market, no backup grid, and no pipeline.
Generates and distributes all of Nunavut\'s electricity from 25 stand-alone diesel plants in 25 communities. About 15,500 customers. No retail competition.
No roads or pipelines. Diesel and heating oil are shipped in bulk during the brief summer ice-free window and stored on site, so fuel security is a year-round concern.
The six guides, organized by what you need
The first cluster explains the system you live in; the second covers the structured pathways off diesel. Read the keystone first, then follow whichever thread matches your question.
One public utility, 25 isolated diesel grids, no interconnection, and fuel that arrives once a year by sealift. Start here: this architecture is the reason every other Nunavut energy fact looks the way it does, from heating to outage risk.
Qulliq Energy Corporation runs 25 stand-alone diesel power plants in 25 communities, with no shared grid, no roads or power lines between them, and no backup. Fuel arrives once a year by summer sealift and is stored on site. This is the most isolated power system in Canada, and it explains everything else about energy here.
Nunavut heats almost universally with delivered fuel oil, stored on site and resupplied by the same summer sealift that brings diesel for power. Running out is a real risk, not an inconvenience. This guide covers the practical reality of oil heat in the Arctic alongside the qulliq, the seal-oil lamp at the heart of Inuit warmth and light.
In a fly-in, sealift-only community a winter outage is a life-safety event, and the deeper risk is fuel security: if the annual resupply or on-site storage falls short, there is no pipeline or grid to fall back on. Here is how to prepare a household and why the community's tank farm is the real backstop.
The structured pathways off diesel: QEC's net metering and Inuit-led power-producer programs, the proposed Kivalliq Hydro-Fibre Link, and the efficiency levers that work in an Arctic climate with few formal rebates.
QEC's Net Metering Program lets residential and municipal customers generate up to 15 kW of renewable power and feed surplus back for credits, while the Commercial and Institutional Power Producer and Independent Power Producer programs let businesses, governments and Inuit-owned organizations sell to the utility. The economic ceiling worth understanding is the avoided cost of diesel.
A proposed 1,200 km power-and-fibre corridor from northern Manitoba to Nunavut's Kivalliq region, led by the Inuit-owned Nukik Corporation, would connect five communities and area gold mines to Manitoba's hydro grid, displacing roughly 138 million litres of fuel and about 371,000 tonnes of greenhouse gas a year. It is the project to watch, still in planning, with cost and timeline in a dated box.
Nunavut has fewer formal rebate programs than other territories, so the durable levers are behavioural and structural: insulation, draft-proofing, heat retention, and net metering for those who can install it. This is an honest efficiency guide that points to Nunavut Housing Corporation and federal and territorial clean-energy initiatives rather than a fabricated rebate catalogue.
