Canadian bitcoin miner Hut 8 is taking a contract dispute with its energy provider to court.

The miner filed a statement of claim in the Superior Court of Justice of Ontario against Validus Power Corp. and its subsidiary, Bay Power Corp., the third-party energy supplier to Hut 8's facility in North Bay, Ontario, according to a Thursday press release.

The company said in October that it would try to settle the dispute through mediation.

Hut 8 claimed that Validus "failed to achieve certain key operational milestones" on schedule, while also demanding more money than what was agreed under the power purchase agreement (PPA). On a Nov. 28 update, it said that Validus cut power to the North Bay site and issued a default notice for failed payments, which Hut 8 denied.
