Québec Bitcoin Mining — Power, Rates, Rules & Local Services

🇫🇷 En français : Réparation ASIC et achat de mineurs au Québec & à Laval

Everything for Bitcoin mining in Québec — Hydro-Québec rates, the regulatory rules, data-sovereignty laws, and hands-on repair and AI consulting from D-Centrals Montreal bench, grouped by theme.

Quick answer

Québec is one of the best places on earth to mine Bitcoin: abundant, cheap hydroelectric power, a cold climate that helps cooling, and the lowest industrial power rate in North America — 3.821 ¢/kWh on Rate L. A Bitcoin miner cannot buy power at that price. Any load with 50 kW or more dedicated to blockchain work is barred from Rate L and billed on Rate CB instead, where energy outside your authorized allocation costs 18.767 ¢/kWh — roughly 4.9× Rate L — on a non-firm contract that Hydro-Québec may curtail for up to 300 hours a year on two hours of notice. New allocations from the dedicated block have been suspended since the January 2023 Régie decision, so the real question in Québec is not what power costs; it is whether you can get an allocation at all. This hub gathers D-Central's Québec resources: the exact rates, the rules, the data-sovereignty laws, and hands-on repair and consulting from our Montreal bench.

Cheap hydro + cold climate make Québec ideal for mining — but power allocation is capped. Start with the rates and rules below, then talk to a local team that actually mines and repairs here.

Power & rates

Québec has North America's cheapest power — but a Bitcoin miner is not allowed to buy it at that price.

Rules & data sovereignty

Mining is legal in Québec, but Hydro-Québec caps the power allocated to it — and Québec has its own data laws.

Quebec energy-regulation status

What actually governs Bitcoin-mining electricity in Quebec is not the famous cheap industrial rate — it is a dedicated blockchain tariff, two live rate cases, and a ministerial gate. As of 2026-07-15:

Instrument	Status	Price / effect	What it means for miners
Rate CB — Rate for Cryptographic Use Applied to Blockchains (Hydro-Québec Electricity Rates, Chapter 7) tariff	In force	18.767 ¢/kWh on all consumption other than an authorized allocation — a miner with no allocation pays this on every kWh. Inside an authorized allocation: 6.292 / 4.666 ¢/kWh (medium power) or 4.324 ¢/kWh (large power). During a curtailment, consumption above the reduced cap is billed at $1.038/kWh. Effective April 1, 2026.	A new Quebec miner with no grandfathered allocation bills its entire draw at 18.767 ¢/kWh — roughly 4.9× Rate L (3.821 ¢) — and is locked out of the cheap industrial rates. Authorized demand is frozen (Art. 7.2) and service is non-firm: curtailable to 5% of peak for up to 300 h per rate-year on 2 h notice (Art. 7.9).
Proposed Rate CB adjustment (3-year transitional pricing for existing cryptographic-use customers) tariff	Under hearingFiled 2026-02-19 · Régie de l'énergie — hearing Fall 2026 · Decision Late 2026 / early 2027 (being challenged)	Would raise Rate CB to an average of about 19.5 ¢/kWh under a 3-year transitional pricing plan for current Rate CB customers.	Existing Quebec miners on Rate CB would see their rate rise toward ~19.5 ¢/kWh on average over a 3-year transition. Proposed and contested — not yet approved by the Régie.
Rate CD — proposed rate for large data centres (≥5 MW) tariff	Under hearingFiled 2026-02-19 · Régie de l'énergie — hearing Fall 2026 · Decision End 2026 / early 2027 (requested effective 2026-11-01; operators intend to challenge)	About 13 ¢/kWh on average — roughly double the current large-power rate.	A Bitcoin-mining or AI hashcenter of 5 MW or more would be moved onto Rate CD at ~13 ¢/kWh — about 2× today's large-power price. Proposed; the requested effective date is Nov 1, 2026, subject to the hearing.
Bill 69 — An Act to ensure the responsible governance of energy resources and to amend various legislative provisions (2025, chapter 24) statute	In forceFiled 2025-06	Not a price. Hydro-Québec or any supplier must obtain authorization from the Minister of Economy, Innovation and Energy (MEIE) before serving 5 MW or more to a requester that has no financial-commitment agreement predating December 2, 2022; the Minister may attach economic, social and environmental conditions. The Minister also holds approval authority over crypto-mining electricity demands of 50 kW or more.	Grid access for large loads is now a discretionary ministerial gate, not just a tariff. A new Quebec mining or AI site ≥5 MW needs MEIE authorization (which can carry conditions), and any crypto-mining demand ≥50 kW is subject to ministerial approval — on top of Rate CB and the frozen allocation. Adopted (assented) June 2025.
Bill 2 — An Act mainly to cap the indexation rate for Hydro-Québec domestic distribution rate prices (2023, chapter 1) statute	In forceFiled 2023	Caps the annual indexation of Hydro-Québec DOMESTIC (residential) distribution rate prices. Included for completeness — low direct relevance to miners.	Does NOT set the miner's rate. Miners are on Rate CB (or a commercial rate such as G or M), not domestic Rate D, so this cap does not lower a mining operation's power cost. Listed for completeness only.
Dedicated blockchain / crypto electricity allocation block (Rate CB) allocation	Suspended	A dedicated block of electricity — reported at roughly 300 MW (a figure Hydro-Québec now describes as under reassessment) — was reserved by the Régie de l'énergie for blockchain / cryptographic use at Rate CB. The process for granting NEW allocations from that block is suspended.	A new Quebec miner cannot currently obtain authorized capacity: new allocations from the dedicated block have been suspended since early 2023 (Régie de l'énergie, docket R-4210-2022), and Rate CB Art. 7.2 freezes authorized demand to what was already held or won through an allocation award. Without an allocation, the operation's entire draw bills at 18.767 ¢/kWh.

The real cost is not on the meter — it is sovereignty

Read the table as policy, not a price list. A Bitcoin mine or AI hashcenter in Quebec with no allocation pays 18.767 ¢/kWh, and the two rate cases before the Régie would set ~13 ¢ for data centres and ~19.5 ¢ for blockchain load — roughly 2–3× competitive U.S. mining power (~4–7 ¢/kWh on low-cost grids like Texas) and ~3–5× Quebec’s own Rate L of 3.821 ¢, the “cheapest power in North America” a miner is now barred from. See the full electricity-cost comparison.

No operator exports hashrate or a data centre to a jurisdiction that costs three times the alternative, so the infrastructure gets built south of the border — and Quebec’s one durable advantage in the digital age, abundant clean hydro, stops converting into anything Quebecers own.

That is the real loss, and it is not provincial. In an economy that runs on compute, AI and data, a place is sovereign only to the degree it owns its digital infrastructure instead of renting it from someone else’s servers. Mining and AI compute are how you turn cheap energy into owned hashrate, compute and data capacity under local control. Price that industry out and you do not trim a niche — you hand the foundation of your digital future to whoever kept their power cheap. Quebec is the sharpest case because it holds the hydro; the exposure is Canada-wide.

The gates also fall hardest on the operators decentralization depends on: Bill 69’s ministerial approval for every ≥5 MW load and every ≥50 kW crypto demand, stacked on a frozen allocation, is absorbable by a hyperscaler and fatal to a sovereign, small or home miner — centralization written into the rate schedule. The answer is to own the stack: self-hosted compute, local AI you control, and decentralized infrastructure no one can price out or switch off — the build these rules make harder, and more necessary.
