Crypto Mining Moratorium in New Brunswick: What It Means for Miners and the Grid

When New Brunswick shut down new cryptocurrency mining connections in 2023, it didn’t just make a policy change - it sent a clear message: electricity isn’t for sale to energy-hungry Bitcoin mines. This isn’t a temporary pause. It’s a full stop. And it’s one of the strictest moves any Canadian province has made against crypto mining.

Why New Brunswick Said No

Back in March 2022, the provincial government quietly ordered NB Power, the Crown-owned utility, to stop taking new requests for electricity from crypto mining operations. At first, it looked like a delay. But by November 2023, that pause became a permanent ban. No new mines. No expansions. No exceptions.

The reason? Simple: the grid couldn’t handle it. New Brunswick relies heavily on hydroelectric power, which is clean and renewable - but it’s not infinite. When crypto mining companies started showing up with requests for tens or even hundreds of megawatts, officials realized these operations could swallow up a huge chunk of the province’s total power supply.

Think about it this way: in 2022, Manitoba Hydro estimated that just the crypto miners who had already expressed interest could have added 4,600 megawatts of demand. Manitoba’s total grid capacity at the time was 6,100 megawatts. That’s over 75% of the entire province’s power going to machines that only exist to solve math problems. New Brunswick saw the same risk - and chose to protect its residents’ electricity instead.

What the Ban Actually Covers

This isn’t just about new mines. The moratorium blocks everything:

• New crypto mining facilities trying to connect to the grid
• Existing mines trying to add more machines or expand their power use
• Any request for increased electricity supply tied to cryptocurrency operations

The rule targets Proof of Work mining - the kind used by Bitcoin and other coins that rely on massive computing power to validate transactions. These operations use more electricity than entire small towns. A single large Bitcoin mine can consume as much power as 30,000 homes.

NB Power doesn’t have to approve any new connections. It doesn’t even have to respond to inquiries. The directive is absolute. And there’s no end date. No review. No sunset clause. It’s open-ended, and that’s intentional.

How It Compares to Other Provinces

New Brunswick isn’t alone in cracking down - but it’s the most extreme.

• Manitoba extended its ban until April 2026, but it’s still temporary. They’re watching, waiting, and might reconsider.
• British Columbia passed Bill 24 to give BC Hydro legal power to cap crypto mining usage. They even won a court case against a mining company trying to force more power access.
• Hydro-Québec raised rates and capped allocations, making mining less profitable without outright banning it.
• Alberta is the opposite. With deregulated energy and pro-mining policies, it became Canada’s crypto mining hub after China’s 2021 ban.

New Brunswick didn’t try to tax it, regulate it, or make it expensive. It just said no. No paperwork. No negotiations. No exceptions.

The Bigger Picture: Energy, Environment, and Equity

This isn’t just about crypto. It’s about who gets to use limited public resources.

Electricity is a public good. When a mining operation draws 50 megawatts from the grid, that’s 50 megawatts that can’t go to homes, hospitals, or electric buses. In a province with aging infrastructure and rising energy costs, that’s a hard trade-off.

Globally, at least eight countries have banned crypto mining outright. China’s 2021 shutdown - which kicked out 75% of the world’s Bitcoin miners - forced the industry to scatter. Many moved to North America. But now, even places with cheap hydro power are saying no.

The environmental argument is clear: Bitcoin mining uses more electricity annually than entire countries like Argentina or the Netherlands. That’s not sustainable. And as governments push to electrify transportation and heating to fight climate change, diverting power to mining machines looks increasingly irresponsible.

What’s Happening Now?

The ban has already reshaped the industry.

Miners who once targeted New Brunswick for its clean, low-cost hydro power are now looking elsewhere. Alberta is the main winner - its deregulated market and pro-business attitude make it the go-to spot for crypto operators in Canada. Some have even moved to the U.S., where states like Texas and Georgia offer cheap power and fewer restrictions.

Existing mines in New Brunswick? They’re stuck. They can’t grow. They can’t upgrade. If they break down, they can’t replace equipment without needing more power - which is now off-limits. Many are quietly shutting down or downsizing.

The ripple effect? Electricity prices in New Brunswick have stayed stable. Residential rates haven’t spiked. The grid hasn’t overloaded. And for residents, that’s what matters.

What’s Next?

There’s no sign the ban will lift. No committee is reviewing it. No politician is pushing to change it. The government’s stance is clear: protecting the grid is more important than attracting a volatile, high-risk industry.

If crypto mining technology changes - say, if a new consensus method uses 90% less power - the ban might be reconsidered. But for now, Proof of Work mining remains a relic that New Brunswick refuses to support.

This isn’t a fight against Bitcoin. It’s a fight for fairness. It’s about making sure public infrastructure serves the public - not a handful of companies running servers 24/7 for profit.

The rest of Canada is watching. If New Brunswick’s model works - stable power, no rate hikes, no grid stress - more provinces may follow. The message is simple: if your business needs more electricity than a city, you don’t get to take it from the people who need it most.
