French lawmakers are looking at Bitcoin mining as a way to make use of the country’s unused electricity. A proposal submitted on July 11 calls for a five-year pilot that would use excess power, mostly from France’s nuclear grid, to mine Bitcoin. The idea is simple: instead of letting unused energy go to waste, turn it into money. Lawmakers believe just one gigawatt of surplus power could bring in as much as $150 million a year.
Matching Power Spikes with Mining Rigs
About 70 percent of France’s electricity comes from nuclear energy. That’s steady and reliable, but not always easy to match with demand. Sometimes the grid ends up with more power than it needs, especially at night or during low-use periods. Rather than dump that energy or sell it cheap, the plan is to install Bitcoin mining rigs close to nuclear plants. These rigs could power up or shut down based on how much energy is available, helping smooth out the grid without adding new infrastructure.
Covering the Costs of Idle Reactors
Even when demand is low, nuclear plants keep running, which costs money. That steady output can become a liability. Bitcoin mining offers a way to recover some of those costs. Reports cited in the proposal suggest mining could turn unneeded energy into direct income. It also reduces the need to constantly throttle reactors, which puts wear on the system and drives up maintenance.

Don’t Let the Heat Go to Waste
Anyone who’s seen a mining setup knows how much heat they throw off. Instead of wasting it, the proposal suggests using that heat for other industries. Think greenhouses, local heating systems, and even some industrial processes. Finland has already done something similar. If France follows through, Bitcoin mining could double as a heating source for nearby communities.
Pilot Program Would Start in Brittany
If the plan moves forward, the pilot would likely launch in Brittany. It would run for up to five years, with a six-month check-in to see if things are on track. France’s Council of State would oversee it, and the results would be sent back to lawmakers to decide if the idea deserves a permanent spot in the country’s energy policy.

France Is Not Alone in This Idea
France is not the only country trying to make Bitcoin mining work for its grid. Belarus is studying how to use extra power for mining. Pakistan has already set aside 2,000 megawatts for mining and AI projects. In the United States, Texas is using Bitcoin mining to help balance a grid full of wind and solar. France’s proposal fits into this growing trend of treating mining as part of the energy system, not something outside of it.
Profit Potential Comes with Risk
This idea sounds smart on paper, but it comes with challenges. Bitcoin prices can swing wildly, and mining is only profitable if the numbers add up. There’s also the environmental impact. Even if the electricity is “leftover,” running a ton of mining rigs still puts pressure on the grid and local infrastructure. Lawmakers will also have to manage regulation, zoning, and potential pushback from communities.
A New Role for Old Buildings and Jobs
If it works, the plan could give new life to abandoned industrial spaces. Factories that once sat empty could be filled with mining rigs. That would bring tech jobs to regions that haven’t seen much investment in years. It would also show that France is ready to support the digital asset industry in a practical way.
What to Watch Next
The first checkpoint comes six months into the pilot. Lawmakers want clear answers: is the project making money, is it helping the grid, and is it worth expanding? If the results are positive, France may start treating Bitcoin mining as a long-term piece of its energy plan, not just an experiment.
