Saber Power recently completed the electrical infrastructure to power Helios, Argo Blockchain’s 200 MW flagship bitcoin mining facility in Dickens County, Texas.
The fast-track project included the construction of a 345 kV substation and 35 kV distribution system on a turnkey, EPC basis. It involved the design and construction of a 345-34.5 kV substation with two 150 MVA transformers, ten 34.5 kV feeders, and 100 distribution transformers to power the mining machines. As part of the installation, Saber also installed more than 100 miles of medium and low-voltage power cable.
The facility was successfully energized Wednesday, May 4. Phase 1 of Helios’ development will utilize 200 MW of power capacity and represents an increase of 243 percent in Argo’s hashrate to an anticipated 5.5 EH/s by the end of 2022 as the Company significantly scales up its mining operations.
Helios also has access to up to an additional 600 MW of power capacity, which the Company expects to utilize in the coming years through further phases of development at the site. It is anticipated this additional capacity, along with further development of the site, will enable Argo’s operations to grow significantly to more than 20 EH/s.
Helios has been designed to house one of the largest immersion-cooled mining operations in the world, which is expected to be more cost-efficient, extend the life of the mining machines by reducing machine exposure to dust and debris and improve operational performance.
