Mining in Quebec: Yes… But With Strict Rules

Cryptocurrency mining in Quebec is possible, but it is tightly regulated. If you don’t follow Hydro-Québec’s rules, you could face serious consequences: retroactive billing or being switched to a much higher electricity rate.

The 50 kWh/h Rule

Hydro-Québec applies a limit of about 50 kWh per hour for the standard residential rate.

With a typical 240V – 200A residential installation, it’s almost impossible to exceed this threshold. However, exceptions exist:

• If you have a 400A panel

• If you run two separate 200A lines on the same property

In these cases, the rules become less clear. Does the 50 kWh/h cap apply per meter or to the entire property? This gray area is where many miners run into trouble.

The Risk of Exceeding the Limit

If Hydro-Québec determines that you’ve gone over the threshold, your entire consumption can be re-billed at the commercial rate — around $0.15/kWh.

At that price, mining quickly becomes unprofitable. A retroactive bill can reach tens of thousands of dollars, enough to wipe out profits and, in some cases, even push small miners into bankruptcy.

The Most Important Advice

To protect yourself, the smartest step is to request written confirmation from Hydro-Québec before you start.

A simple letter can clarify whether your installation complies with the rules, especially if you have multiple lines or a non-standard setup. This precaution can save you from unexpected financial disaster and give you peace of mind.
