Churchill Falls 2.0: The $70 Billion Bet That Could Rewrite Canada’s Energy Map

2026-09-27

For more than half a century, Churchill Falls has been Canada’s most famous bad deal. A giant hydro station in Labrador sold its power to Quebec for a fraction of a cent, and Newfoundland and Labrador watched Hydro-Québec turn that bargain into billions. That chapter is closing. On August 17, 2026, Newfoundland and Labrador, Quebec and Ottawa announced a new agreement to replace the 1969 contract and launch one of the largest clean energy build-outs on the continent. On September 17, the Newfoundland and Labrador House of Assembly approved it by a narrow 21 to 18 vote. Negotiators are now working on the final binding agreements.

This article covers what is being built, how it compares with the world’s largest dams, what it will cost, who benefits financially, and what it means for green energy, power prices and carbon emissions.

A Short History: How the 1969 Contract Went Wrong

Churchill Falls opened in 1971 with a capacity of about 5,428 megawatts (MW). It produces roughly 30 to 35 terawatt-hours (TWh) of electricity a year. Its underground powerhouse, carved out of solid rock, was an engineering landmark.

The problem was geography. The only practical route to market ran through Quebec, and Quebec used that leverage. Under the 1969 contract:

Hydro-Québec paid about 0.3 cents per kilowatt-hour (kWh), falling to roughly 0.2 cents over time.
There was no inflation adjustment.
The contract ran 40 years, then renewed automatically for 25 more at an even lower price, through 2041.

Then came the energy crises of the 1970s and decades of inflation. Hydro-Québec resold the power at market rates, sometimes more than 20 times what it paid. By one widely cited estimate, Hydro-Québec had earned about $28 billion from Churchill Falls by 2019, roughly 14 times what Newfoundland and Labrador received.

How the New Deal Came Together

Date	Event
December 2024	Premiers Andrew Furey and François Legault sign a memorandum of understanding (MOU) to replace the 1969 contract
October 2025	Tony Wakeham’s Progressive Conservatives win the provincial election, promising an independent review and a referendum
August 17, 2026	A renegotiated deal is announced with the federal government as a financial partner; the referendum is dropped
September 17, 2026	House of Assembly approves the deal 21 to 18
October 5, 2026	Quebec provincial election, a key political risk
Next	Negotiation of the final “definitive agreements”

Premier Wakeham said the federal partnership and pressure from U.S. tariffs were the reasons he cancelled the referendum.

What Is Being Built

The package is valued at close to $70 billion, described by Ottawa as the largest clean energy investment in North American history.

Project	Added capacity	Timing
Churchill Falls turbine upgrades	about 1,275 MW (station rises to roughly 6,700 MW)	One unit per year, starting in the 2030s
Gull Island hydro dam (downstream on the Churchill River)	up to 2,700 MW, about 12 TWh per year	Expected online 2036 to 2037
Labrador onshore wind	about 2,000 MW	No firm schedule yet
Transmission, including a new Labrador West line	660+ km of new lines	Alongside the generation projects

Including possible further expansion at Churchill Falls, governments describe the full program as close to 14,000 MW of clean capacity over time.

How Churchill Falls Compares With the World’s Largest Dams

Hydro plant	Country	Capacity (MW)
Yarlung Tsangpo / Medog (under construction)	China	about 60,000 (planned)
Three Gorges	China	22,500
Baihetan	China	16,000
Itaipu	Brazil and Paraguay	14,000
Xiluodu	China	about 13,900
Belo Monte	Brazil	about 11,200
Guri	Venezuela	about 10,200
Wudongde	China	about 10,200
Churchill River system after build-out	Canada	about 10,000+
Tucuruí	Brazil	about 8,400
Grand Coulee	United States	about 6,800
Churchill Falls after upgrades	Canada	about 6,700
Robert-Bourassa (LG-2)	Canada	about 5,600
Churchill Falls today	Canada	about 5,430
Grand Ethiopian Renaissance Dam	Ethiopia	about 5,150

What this means:

As a single station, an upgraded Churchill Falls would rank roughly in the world’s top 12 to 15 and rival Grand Coulee as the largest in North America.
As a river system, Churchill Falls, Gull Island and Muskrat Falls together would reach about 10,000 MW. That puts it in the same league as Guri and Wudongde, and about half the size of Three Gorges.
On cost, Churchill Falls stands out. A huge natural drop and a vast reservoir make it one of the cheapest large power sources on earth to operate.

The Financial Costs

The headline number: about $70 billion

The $70 billion covers the upgrades, Gull Island, wind and transmission. Governments have not published a detailed cost breakdown by project. Final costs, contingency allowances, ownership percentages and interest terms are still being negotiated.

Who pays

Hydro-Québec and Newfoundland and Labrador Hydro, both Crown corporations, will fund and own most of the generation. Under the 2024 framework, Quebec agreed to carry construction risk and cost overruns on the Churchill Falls and Gull Island projects. Whether that protection survives unchanged in the final 2026 agreements is one of the most important details to watch.
Hydro-Québec also pays about $3.5 billion in incentive and development payments to help Newfoundland and Labrador Hydro fund its equity share.
Ottawa has committed up to $10 billion in financial support. Most of that is financing and loan guarantees, not grants. It includes:
- about $1 billion for an equity stake of up to 40% in the wind project
- about $1 billion for the Labrador West transmission line
- about $1.5 billion for Gull Island, Churchill Falls and transmission support
- federal loan guarantees for Gull Island construction

The risk: remember Muskrat Falls

Newfoundland and Labrador has been burned before. The Muskrat Falls project, further down the same river, was budgeted at about $6.2 billion and ended up costing more than $13 billion. It finished years late, and the province has had to spend heavily to keep power bills from doubling.

Megaprojects of this size often run over budget. Gull Island is the piece most exposed to that risk. The federal loan guarantee helps because it lowers borrowing costs, and interest rates are one of the biggest drivers of hydro project economics. But a guarantee does not make cost overruns disappear. It only shifts who absorbs them.

The Financial Benefits

For Newfoundland and Labrador

This is where the change is dramatic.

Measure	Old 1969 contract	New deal
Price Hydro-Québec pays	about 0.2 cents per kWh	about 6 cents per kWh (roughly 30 times more)
Annual revenue to 2041	about $20 million a year	about $1 billion a year (2024 MOU estimate)
Total value to the province	small	about $49 billion in today’s dollars; about $273 billion over the full term

Other benefits for the province:

Retained power of up to 2,350 MW from Churchill Falls and Gull Island, plus 400 MW from the wind project, for local industry and mining.
The option to sell retained power to Hydro-Québec at a 50% premium over base contract prices.
Guaranteed access to export markets of 985 MW, including New York City and New England, at the prices Hydro-Québec receives.
A 15% residential electricity rebate on the first 2,000 kWh a month, worth about $351 a year per household. Across roughly a quarter of a million households, that works out to somewhere around $80 to $90 million a year (my own rough estimate).
Jobs: about 5,000 workers at Gull Island’s peak, with 85% local hiring guarantees.
Mining growth in the Labrador Trough, one of Canada’s richest iron ore regions, thanks to the new transmission line.

For a province with the highest per-capita debt in Canada, an extra billion dollars a year is a very big deal.

For Quebec

Quebec gives up nearly free power years early, but it still does well:

Hydro-Québec pays about 6 cents per kWh, which it says is roughly one-third the cost of building new supply in Quebec.
Access to Labrador power is secured until 2077, well beyond 2041.
Quebec’s own electricity surplus is disappearing as demand grows from electric vehicles, heat pumps, industry and data centres. This deal fills the gap without building gas plants.

A rough way to see the value: if new supply elsewhere would cost around 18 cents per kWh and Labrador power costs 6 cents, every terawatt-hour saves about $120 million. Gull Island’s 12 TWh alone could save Quebec on the order of $1.4 billion a year compared with the alternatives (my estimate, based on Hydro-Québec’s own cost comparison).

For Canada

About $31 billion added to national GDP through the early 2040s.
About 23,000 construction jobs.
A stronger clean power export position into the U.S. Northeast.
A major federal political win in a long-standing interprovincial dispute.

Cost and benefit at a glance

	Costs	Benefits
Newfoundland and Labrador	Equity investment in new projects, overrun risk if protections weaken, Muskrat Falls-style risk	About $49B in present value, about $1B a year before 2041, power rebates, jobs, mining growth
Quebec	Much higher price than the old contract; early loss of near-free power	Long-term supply at about one-third the cost of alternatives, secured to 2077
Ottawa	Up to $10B in financing, guarantees and equity	GDP growth, jobs, emissions cuts, political resolution
Ratepayers	Possible overrun costs passed through over time	Lower bills in Newfoundland and Labrador; slower rate increases in Quebec

What It Means for Green Energy

Firm clean power is the real prize. Wind and solar only produce when the weather cooperates. Hydro reservoirs can be ramped up and down on demand. The Churchill Falls upgrades add mostly peaking capacity, meaning power available on the coldest winter evenings when grids are most stretched.

New clean energy. Gull Island (about 12 TWh a year) plus the wind project (perhaps 6 to 8 TWh a year) could add 18 to 20 TWh of new clean electricity each year. That is roughly the annual use of 1.5 to 2 million Canadian homes.

Wind and water work well together. When the wind blows, water stays in the reservoir. When the wind stops, the turbines pick up the slack. Few places in the world can pair wind and large-scale hydro this effectively.

The environmental costs are real. New reservoirs flood land and can release methylmercury into fish, a major controversy at Muskrat Falls. The original Churchill Falls development flooded Innu land without consent, so a genuine partnership with the Innu Nation is central to this deal’s legitimacy.

What It Means for Energy Prices

Newfoundland and Labrador: Direct relief through the 15% rebate, plus new revenue to help cushion Muskrat Falls costs.
Quebec: Already among the lowest rates in North America. Cheaper new supply should help keep future increases modest.
New York and New England: Imports will ease wholesale prices and winter spikes a little, but the volumes are small relative to those markets.
Alberta and Western Canada: No direct effect, since the grids are not meaningfully connected. The indirect effect is a stronger national case for clean power and interprovincial transmission.

What It Means for the Global Carbon Footprint

The existing Churchill Falls power is already clean, so re-pricing it does not cut emissions. Only the new energy counts.

A rough estimate:

About 18 to 20 TWh of new clean supply, if it replaces natural gas power, avoids about 7 to 8 million tonnes of CO2 a year.
That is about 1% of Canada’s annual emissions and about 0.02% of global emissions.
Valued at Canada’s federal social cost of carbon (roughly $250+ per tonne), those avoided emissions are worth about $2 billion a year to society.

On a global scale, one project will not move the needle. China adds this much clean capacity in a matter of weeks. The real significance is regional: it is one of very few ways Eastern Canada and the U.S. Northeast can add large amounts of round-the-clock clean power. Because the new capacity arrives in the mid-2030s, the climate benefit comes later, and any delay pushes it back further.

For Investors

Hydro-Québec and Newfoundland and Labrador Hydro are Crown corporations, so there is no direct way to buy shares in this project. The indirect exposure is through companies that could play a role in construction, engineering, transmission or distribution, as well as regional utilities and Labrador Trough miners that could benefit from cheaper, more plentiful power. As always, government megaprojects carry long timelines and political risk, so any investment thesis built on this deal needs patience and a healthy margin of safety. This is not investment advice; do your own research.

The Bottom Line

The new Churchill Falls agreement does three big things:

It corrects a lopsided 1969 contract. Newfoundland and Labrador goes from about $20 million a year to about $1 billion a year, with about $49 billion in present value over the life of the deal.
It adds about 4,000 MW of firm clean hydro and 2,000 MW of wind for Eastern Canada and the U.S. Northeast in the 2030s.
It makes the Churchill River one of the world’s top-tier hydro systems, and one of the cheapest to run.

The biggest risks are still ahead: the October 5 Quebec election, the final commercial terms, the partnership with the Innu Nation, and whether Gull Island can avoid the cost overruns that made Muskrat Falls a cautionary tale. If those hurdles are cleared, this could turn Canada’s most famous bad deal into one of its best.

Figures are based on government announcements and media reports as of September 2026. Several financial details, including final project costs and ownership shares, have not yet been published. Estimates marked as my own are rough calculations for illustration.
