  • Prince George (2.4 EH/s, 85MW – BC, Canada)
    • Foundation works complete for the first two data center buildings (10MW and 20MW), and have commenced for the third data center building (20MW)
    • Structural steel for the first 20MW data center building has arrived on site ready for erection
  • Childress (9.6 EH/s, 335MW – Texas, USA)
    • Construction commenced in April with initial ground-breaking and access road works underway
    • Delivery of the first 100MW of data center buildings remains on track for the end of 2022, with energization expected in Q1 2023

Canal Flats update (0.8 EH/s, 30MW) – BC, Canada

Canal Flats (100% renewable operations since inception³) achieved average monthly operating hashrate in April of 870 PH/s, a 2% increase on March (850 PH/s), driven by the optimization of rack space. The project continues to exceed previously announced site capacity of 0.7 EH/s.

Mackenzie update (2.4 EH/s, 80MW) – BC, Canada

The initial 0.3 EH/s (9MW) at Mackenzie was successfully commissioned ahead of schedule on April 12. The commencement of operations marks the delivery of the Company’s second operating site in BC, Canada. The project achieved monthly average operating hashrate of 168 PH/s in April (reflecting commissioning of 0.3 EH/s mid-month).

Construction of the remainder of the first 1.5 EH/s (50MW) remains on track for Q3 2022, with the additional 0.9 EH/s (30MW) expected in 2023. Major electrical equipment installation is underway (including the substation), along with internal fit out of all three data center buildings.

Upon completion, the proprietary data centers are expected to power an additional ~24,000 Bitmain S19j Pro and S19j miners (already secured), generating 2.4 EH/s of incremental hashrate and adding approximately 15-20 direct full-time local jobs in Mackenzie.

Prince George update (2.4 EH/s, 85MW) – BC, Canada

Foundation works are complete for the first and second data center buildings (10MW and 20MW) at Prince George and have commenced for the third data center building (20MW). Structural steel for the first 20MW data center building has arrived on site ready for erection, with concrete work underway for the on-site substation and the third data center building (20MW).

The first 1.4 EH/s (50MW), comprising three data centers, remains on track to be energized by the end of Q3 2022, with the additional 1.0 EH/s (35MW) anticipated to come online in 2023.

Upon completion, the proprietary data centers are expected to power an additional ~25,000 Bitmain S19j Pro and S19j miners (already secured), generating 2.4 EH/s of incremental hashrate and adding approximately 20 direct full-time local jobs in Prince George.

Childress update (9.6 EH/s, 335MW) – Texas, USA

Procurement and early construction activities progressed, with first ground-breaking and access road earthworks commencing.

Purchase orders have been placed on key long-lead items, including the 345kV step-down transformer, 138kV step-down transformers and associated circuit breakers.

The first 3.0 EH/s (100MW) of data center buildings are expected to be completed by the end of 2022⁴, with an additional 6.6 EH/s (235MW), comprising S19j Pro miners (already secured), expected to progressively come online through to Q3 2023. Based upon the executed 600MW connection agreement with AEP Texas, the site has the capability to power an additional ~8 EH/s⁵ (265MW) of miners beyond the 15 EH/s already secured.

Upon completion and at full capacity, the proprietary data centers at Childress are expected to generate ~18 EH/s⁵ of incremental hashrate and add approximately 50-60 direct full-time local jobs.

Technical commentary

The Company’s average operating hashrate increased to 1,038 PH/s in April, primarily attributable to the commissioning of the first 9MW at Mackenzie.

* Reflects actual recorded operating power usage and hashrate (not nameplate). Note: nameplate capacity is higher than actual operating power usage due to features of the Company’s proprietary data center design which utilizes variable speed fans to reduce power consumption during cooler months, as well as the Company maintaining a buffer within its infrastructure capacity that can be also directed to other site uses (e.g., in-house fabrication shop at Canal Flats is currently operating as Iris Energy has the advantage of saving time and costs by internally constructing certain components for its expansion sites).

* Reflects Bitcoin mined post deduction of mining pool fees (currently 0.5% x total Bitcoin mined).
