Iris Energy Doubles Operating Capacity to >2.3 EH/s

Mackenzie (50MW) Commissioned Ahead of Schedule

Deployment Options Underway for 6.0 EH/s

SYDNEY, Australia, Aug. 08, 2022 (GLOBE NEWSWIRE) -- Iris Energy Limited (NASDAQ: IREN) (“Iris Energy” or “the Company”), a leading owner and operator of institutional-grade, highly efficient proprietary Bitcoin mining data centers powered by 100% renewable energy, today announced it has approximately doubled its operating capacity to exceed 2.3 EH/s.

The Company recently energized the remainder of the first 1.5 EH/s (50MW) at its second operating site in Mackenzie, BC (Canada), which marks delivery of phase two of the project. Both initial phases have been commissioned ahead of schedule:

  • Phase one: 0.3 EH/s (9MW) – April 13, 2022 (original target end of Q2 2022)
  • Phase two: 1.2 EH/s (41MW) – August 5, 2022 (original target end of Q3 2022)

The Company’s next site, in Prince George, BC (Canada), also remains on track to be energized by the end of next month and is expected to add a further 1.4 EH/s (50MW), increasing the Company’s near-term operating capacity to 3.7 EH/s.

In addition:

  • The Company continues to work through deployment options for its remaining 2.3 EH/s of miners, including the recently announced 1.7 EH/s of Bitmain S19j Pro miners to be shipped in August 2022, increasing expected operating capacity to 6.0 EH/s
  • $46.7 million of the previous $130 million of payments made to Bitmain have been applied to secure the additional 1.7 EH/s, and utilization of the remaining $83.3 million of payments in respect of additional contracted miners above the 6.0 EH/s continue to be subject to ongoing discussions with Bitmain1

Iris Energy’s Co-Founder & Co-CEO, Daniel Roberts, said:

“The delivery of Mackenzie is another important milestone for the Company. We are particularly pleased to continue our track record of delivering projects on schedule, despite the current market backdrop and ongoing international supply chain challenges. We would like to thank the Mackenzie construction team for their ongoing hard work and dedication and to welcome a number of new local hires to the permanent operations team.”
