World-class cheap, clean, abundant hydro. The catch is access: new loads above 5 MW need ministerial sign-off under Bill 69, and a proposed data-centre tariff near 13 cents per kWh lifts the price. Approved projects still connect, so this is a managed gate, not a closed door.

Quebec is a limited market to sell power into

Grade C (Limited)
Offtake score 19/100
Demand 27, build feasibility 16, combined into the score. For a seller: where buyers already pay, how tight supply is, and how feasible new build is here.
Price to beat
A 100 MW load on our standard case pays about $85/MWh delivered here. A competitive supply offer works against that level.
Connection
Connection difficulty Severe, typical wait 4-6 years (authorization-gated).
For new supply
Hydro-Quebec's Action Plan 2035 (about 185 billion CAD) is the new-supply pipeline, developed as partnership with First Nations and Inuit communities.
Regulatory momentum
Mixed, stable. Hydro-Quebec's proposed dedicated data-centre tariff roughly doubles the industrial rate and is pending the Regie de l'energie; managed pricing inside an otherwise open, low-cost system.
Beyond the grid
New supply depends on Indigenous consent: a Quebec First Nation voted to reject a landmark Hydro-Quebec deal, and the utility now frames its large hydro expansion as ongoing partnership with First Nations and Inuit communities rather than one-off settlements.

Quebec: effectively full at system level, rising demand pressure

Effectively full 9/100
System-level room, not local capacity
Local capacity: not assessed. We have found no operator publication of area or substation capacity for this market, so whether the bus serving a candidate site can take the load is an open question. Absence of a finding here is not evidence that capacity exists.
Two reads for a grid planner: how much room the system as a whole looks to have (Effectively full), and how hard demand is already pushing (Rising). The first is a market-level estimate from connection ease, forward adequacy and reliability margin. It is not local deliverability. Capacity at a specific substation is not assessed for this market, and a market can look roomy while the bus you want has nothing available. Confirm local capacity with the utility before relying on it.

Regulatory momentum

The regulatory and permitting environment is increasingly the binding variable for a new large load.
Mixed→ stable

Why: Hydro-Quebec's proposed dedicated data-centre tariff roughly doubles the industrial rate and is pending the Regie de l'energie; managed pricing inside an otherwise open, low-cost system.

What would change the read: The Regie approving a workable dedicated rate with a clear, predictable allocation process.

For new supply: Hydro-Quebec's Action Plan 2035 (about 185 billion CAD) is the new-supply pipeline, developed as partnership with First Nations and Inuit communities.

Beyond the grid: New supply depends on Indigenous consent: a Quebec First Nation voted to reject a landmark Hydro-Quebec deal, and the utility now frames its large hydro expansion as ongoing partnership with First Nations and Inuit communities rather than one-off settlements. Globe and Mail BLG

The five pillars behind the tier

A
A
C
M
C
The pillar signature: Access, Availability, Cost, Momentum, Carbon, taller is stronger. The same shape repeats across every market so peers compare at a glance.
Access30%55

Managed access: Bill 69 (2025) requires ministerial sign-off for new loads over 5 MW, and Hydro-Quebec has proposed a ~13 cents/kWh data-center rate (H2 2026, pending the Regie). Approved projects proceed; this is a high bar, not a shut door.

Availability25%90

Exceptional availability: Hydro-Quebec reservoir hydro is a large, firm, dispatchable surplus.

Cost25%100

Cheapest power on the board, even after the proposed tariff it remains competitive North-America-wide.

Momentum15%30

Momentum stalled: historically attracted AWS/Google/Microsoft, but new large-load growth is paused under the governance regime.

Carbon5%100

Among the cleanest grids on earth (~5 g), almost entirely hydro.

Default weights, which lean toward cost and access rather than carbon: Access 30 · Availability 25 · Cost 25 · Momentum 15 · Carbon 5. Momentum reflects the data-center build already underway, not just stated intentions.
Seller view: Read these the other way: momentum is your customer pipeline, cost is your revenue ceiling, and access is how hard it is to build and sell here, not only to connect.

Reliability overlay

Reliability adjustment: the five-pillar score of 74 is reduced to 67, a deduction of 7 points, reflecting the delivery-reliability and firm-supply risks flagged below. Reliability is reported as five separate layers, never as one combined label, because they answer different questions and a strong answer on one does not cover a gap in another: what has actually failed on the bulk system, what a forward assessment expects of firm supply, how the local network performs, what your contract actually promises, and what your site is designed to ride through. Any one of them can cap the tier.

Historical bulk-system performance: Minor flags found

Major-event damage is largely distribution and sub-transmission; a transmission-connected firm-service load faces materially less exposure, though restoration during large storms is slow.

What this means: A large new load faces occasional exposure here. Monitor conditions and keep a contingency plan.

event-based · Hydro-Quebec 2023 distribution activities

Historical utility-territory delivery performance: Reliability flags found

Storm-fragile delivery: the Apr 5, 2023 ice storm alone was about 59% of that year's unadjusted SAIDI, and 2024 unadjusted SAIDI was 436 minutes per customer (roughly half of 2023). Major-event-adjusted reliability is stable, so the risk is major-event frequency and slow restoration, not blue-sky performance.

What this means: A large new load should expect genuine exposure to forced power cuts (curtailment), price spikes, and delays in getting connected, and should design in backup power or firm supply contracts.

measured · Hydro-Quebec 2024 accountability report

Forward resource adequacy (assessed): No adequacy flags

Contractual service terms: not assessed

We have not compiled what firm service actually promises here: whether it is firm, non-firm or interruptible, the conditions under which you can be curtailed, the redundancy required of you, and the transfer time behind any N-1 commitment. Treat this as an open diligence item, not as an indication that service is firm.

Ask the utility for the tariff or service agreement terms before relying on firm supply.

Designed site resilience: not applicable at market level

Utility feeds, UPS, storage, on-site generation, islanding, black start and the residual energy you still expect to lose are properties of a specific site design, not of a market. This layer only exists once there is a site, and we never assert it for you.

Confidence: Med-High. Each input is labelled as measured, modelled, or drawn from a specific event, and is framed as a risk to a prospective large new load, not as a verdict on any utility or grid operator. Forward adequacy is an assessment of what is expected, not a measurement of what has happened; it is a forecast and is labelled as one.
Seller view: Tight forward capacity (firm supply promised for future years) is scarcity that firm generation and storage get paid for; an adequacy flag is a demand signal for new supply, not only a risk to a load.

Supply relief outlook

Will the power crunch ease before your load energizes? This nets the demand racing for capacity against the new supply likely to arrive and the old supply leaving. A cross-side read, using the same data a seller sees the other way.

Cheap hydro, but new large loads are authorization-gated: the Minister must approve any connection of 5 MW or more.

Quebec restricted new power procurement for large data centres in 2024, and under Bill 69 (June 2025) the Minister must authorize any new load of 5 MW or more on technical, economic and social criteria. Hydro-Quebec's proposed dedicated data-centre tariff runs about 13 cents per kWh, roughly double the large-power rate. Cheap, clean hydro is the draw; the gate is ministerial authorization and available capacity pending the Action Plan 2035 build.

Realized cost band

What a large electricity user pays for power here on one declared case, 100 MW contracted demand, 95% load factor, HV service, per megawatt-hour. Not the wholesale price and not the sticker tariff: energy plus the grid, delivery and other charges that land on the bill. It is a range, because real contracts vary, and it is labelled by how it was built.

From 3 public fragments

What sets this band

There is no wholesale spot market here, so the band is not an energy-plus-network stack. It is set by the regulated tariff levels below.
$28
$95
$28$115
Legacy Rate L (large industrial)$28 /MWh
The general large-power industrial tariff, about 3.8 cents CAD per kWh, among the lowest anywhere. It applies to legacy or partial sites, not to a new data center.
Proposed data-centre rate$95 /MWh
Hydro-Quebec's filed dedicated rate for data centres over 5 MW, about 13 cents CAD per kWh, roughly double Rate L, pending the Regie de l'energie. This is what a new data center would pay.
These are the regulated tariff levels that define the band, not an additive cost stack. The band runs from legacy sites near Rate L up to new data centers at the proposed dedicated rate, which is why it is wide. Anchored to published figures (Hydro-Quebec proposed data-centre rate (CBC)).

Where the cost lands

$85
Low $55Midpoint $85High $115
A band, not a single price: the cheaper end is a well-structured contract on favourable terms, the higher end a less optimised one. The midpoint is our best central read.
What is in the number: Quebec has no wholesale market, so the cost is Hydro-Quebec's regulated tariff. The general large-industrial Rate L is about 3.8 cents CAD per kWh (~$28 per MWh), among the lowest anywhere, but Hydro-Quebec has filed to roughly double the rate for data centres specifically, to about 13 cents CAD per kWh (~$95 per MWh), pending the Regie de l'energie, with a still-higher rate proposed for cryptocurrency.

The headline-cheap Quebec hydro rate is misleading for the load we rate: it is the general industrial tariff, not what a new data center will pay. A new data center over 5 MW faces the proposed dedicated data-centre rate of about 13 cents CAD per kWh, roughly double the industrial rate, phasing in over five years for existing sites. The band reflects legacy or partial sites near the industrial rate and new data centers at the proposed data-centre rate; it is a proposal pending the regulator, so it is labelled triangulated rather than measured.

This market's band is free here; the ranked cross-market table with every market's precise midpoint is the Analyst Desk. See the ranked view.

Basis: triangulated from public sources, in US dollars per MWh delivered to a large high-load-factor load, excluding refundable taxes. Sources: Hydro-Quebec Rate L (large-power industrial) · Hydro-Quebec proposed data-centre rate (CBC).

Seller view: This delivered price is the level a competitive supply offer must beat, and the revenue ceiling a merchant plant works against here.

Data provenance and freshness

What we hold for this market, field by field. Each tier below is assigned from the evidence actually held for that field, with provenance. A low tier means we looked and it is thin; it is not a verdict on the market.

Against a Standardized Project Case, the binding field is cost, connection, reliability. That is what a standardized case would turn on here; a readiness result for your own project depends on your own requirements, siting and utility, which this market-level read does not know.
Read against other uses: Discovery and monitoring: M1 · Market comparison: M1 · Project Case with a carbon requirement: M1 · Conditional site diligence: insufficient.
Depth is not a rating strength, a confidence score or a feasibility conclusion. An aggregate is only ever shown for a named use case, and equals the lowest tier across that use case's required fields. Definitions v1.0. See the full coverage matrix.
How solid the data behind this rating is, on two separate axes plus recency. Source reliability is how measured the numbers are, as opposed to triangulated or modelled. Coverage is how many of the decision-relevant data dimensions (reliability, connection, and cost) are compiled for this market. The two are kept apart because they answer different questions: a market can have strong sources on the little that is covered, or broad coverage that still leans on models. Neither grades the rating itself. The rating is a cited opinion, graded separately and falsifiably by the public track record and baseline measurement plan.

What this market can and cannot answer yet

No market-level read closes a project case on its own, and saying only that would waste the evidence we do hold. Below is what is established, what is open, and what to do next.

What is established

  • Recurring cost band $55 to $115 per MWh, midpoint $85, basis triangulated, against the 100 MW archetype
  • Historical bulk-system performance (event-based)

What is open

  • Forward resource adequacy (assessed)
  • Historical utility-territory delivery performance (would change the answer)
  • Contractual service terms (would change the answer)
  • Designed site resilience
  • local_capacity evidence

Who would actually serve you

Not compiled for this market. Identify the serving operator before relying on any figure here, because a market-level read is an average over territories.
Who runs the connection process: not yet compiled for this market. This is wayfinding rather than evidence, and its absence is a gap in our compilation, not a fact about the market.

Credible ranges today

  • Cost $55 to $115 per MWh, midpoint $85 (triangulated)

What could disqualify this market

  • Policy and tariff uncertainty for unapproved new builds.
  • Allocation competition with electrification and exports.

Five questions for the utility or system operator

  1. What is the available capacity at the bulk supply point and substation that would serve this site, and what would a 100 MW request do to it?
  2. Is firm service available at 100 MW, and what curtailment rights would you retain over us once we are energised?
  3. What are the milestone dates from a complete application to full firm energisation, and which network upgrades would a 100 MW load trigger?
  4. What is the all-in delivered rate for 100 MW at a 95% load factor, including demand, network and rider charges, under the tariff that would actually apply?
  5. What is your own territory's SAIDI and SAIFI for the industrial class, on which major-event standard, and what redundancy serves the candidate substation?

Documents that would advance the case

  • The area or substation capacity study, and the current queue position list.
  • The applicable large-load tariff or the draft electric service agreement.
  • The interconnection or system impact study, and a specimen connection offer.
  • The current tariff sheet with all riders, and any large-load contract terms.
  • The utility's own reliability filing and the substation single-line diagram.

Outlook drivers

↑ Upgrade triggers

  • Policy leans into AI growth: streamlined approvals or a dedicated large-load carve-out.
  • New supply from the Action Plan 2035 frees allocation.

↓ Downgrade triggers

  • The gate tightens further or the tariff rises sharply.
  • Strict prioritization keeps new greenfield hyperscale out.

Under reviewThe Cost pillar (currently 100) is placed under review. On closer analysis, the proposed dedicated data-centre rate of about 13 cents CAD per kWh (roughly $95 US per MWh) puts Quebec mid-pack for a new data center rather than lowest in the set; the cheap Rate L (about 3.8 cents) applies to general industry, not to the load we rate.
