The company said that the site of Hut 8 Mining (HUT) in Drumheller in Alberta, Canada, is currently operating at 15% its installed hashrate because of electrical issues. A restoration should be expected in 10-12 week, the company stated on Tuesday .

The first time the miner announced these issues was in March.

The firm stated that “high energy input levels” in the machines have caused “equipment breakdowns” at Drumheller. Meanwhile, the company said that spikes in the energy prices had created “additional obstacles”. Hut 8 is implementing firmware to lower the voltage of its power supply. It also tries to fix machines and hire additional staff.

Hut 8 has not responded to CoinDesk’s request for more information on the Drumheller Mine.

Hut 8 is likely to have a computing power of up to 0.9 exahash/second. The total installed hashrate for its two Alberta locations was 2.6 EH/s by the end of April. The company previously stated that the Medicine Hat site, in Canada’s state of Alberta “hit an operational record” in March with 1.72 EH/s.

Hut 8 was also forced to move 8,000 workers from its third site, located in North Bay, Ontario, to Medicine Hat in mid-November due to a disagreement with its electricity provider. Hut 8 still hasn’t figured out how to make all of these mines operational as of end April.
