Rhea-AI Summary

Iris Energy Limited (NASDAQ: IREN) announced significant operational updates for July 2022, revealing a doubling of its operating capacity to over 2.3 EH/s after commissioning the Mackenzie site. The company mined 154 Bitcoin, resulting in monthly revenue of $3.4 million, despite a rise in electricity costs of $1.36 million. Average operating hashrate slightly decreased to 1,117 PH/s, attributed partly to seasonal factors. Additionally, Iris Energy secured agreements with Bitmain for an additional 1.7 EH/s of miners, boosting expected capacity from 4.3 EH/s to 6.0 EH/s. The company welcomed new executives and reported ongoing construction projects across various sites.

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

Canal Flats has been powered by 100% renewable energy since inception.⁶

The project achieved average monthly operating hashrate of 836 PH/s in July compared to 872 PH/s in June. The slight reduction from June was due to the impact of summer temperatures on our first generation pilot R&D facilities. Canal Flats continued to exceed previously announced site capacity of 0.7 EH/s.

In line with our focus on sustainability across all aspects of our operations, the Canal Flats logistics team recently installed a new green initiative with an expanded polyethylene (EPE) foam densifier, which has the capacity to recycle over two tonnes of EPE per month, derived from miner packaging. The machine reduces the volume of EPE by 90:1, which allows densified EPE ingots to be sold and recycled into a number of new polyethylene products.

Mackenzie update (2.1 EH/s, 50MW initial / 80MW total) – BC, Canada

Mackenzie has been powered by 100% renewable energy since inception.⁶

On August 8, 2022, the Company announced it had energized the remainder of the first 1.5 EH/s (50MW) at Mackenzie, marking 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)

Construction activities at Mackenzie continue to progress for phase three, with the expansion from 50MW to 80MW still on track to be completed by the end of Q4 2022.

The initial 9MW at Mackenzie achieved average monthly operating hashrate of 282 PH/s in July compared to 292 PH/s in June. The slight reduction was in line with expectations and due to the temporary power draw cap of 9MW and increased exhaust fan utilization during the warmer weather, along with scheduled outages associated with the site transitioning to the high voltage transmission network in early August as part of energization of the full 1.5 EH/s (50MW).

Upon completion of all three phases at Mackenzie, 80MW of proprietary data centers are expected to power ~22,000 Bitmain S19j Pro and S19j miners (already under contract), generating 2.1 EH/s of incremental hashrate.

Prince George update (1.4 EH/s, 50MW) – BC, Canada

Building construction is substantially complete on the first and second data center buildings (20MW and 10MW) including all exhaust fans installed, and is close to complete for the third data center building (20MW). Internal fit out of all three data center buildings is underway.

Major equipment installation in the substation has commenced and the underground portions of the on-site distribution network are complete.

Prince George remains on track to be energized by the end of next month and, upon completion, 50MW of proprietary data centers are expected to power ~15,000 Bitmain S19j Pro and S19j miners (already under contract), generating 1.4 EH/s of incremental hashrate.

Childress update – Texas, USA

As previously announced, the Company continues to progress preparatory construction and procurement activities at the 600MW Childress site to preserve the opportunity to scale once market conditions improve.

All required construction permits are in place, construction of the access road to the main development area and site civil works are ongoing, and purchase orders have been placed on key long-lead items, including the 345kV step-down transformer, 138kV step-down transformer and associated circuit breakers.

Potential development options are under consideration, including with respect to the recently announced additional 1.7 EH/s of contracted miners.

Community engagement

Applications for the Community Grants Program at Mackenzie and Childress are now closed. Applications are currently being reviewed, with grants to be made available in due course.

Other notable local community initiatives during the month included sponsoring the 4th of July kids parade in Childress and renewing our support for the Columbia Valley Rockies Hockey Club for the 2022/2023 season.

Future development sites

Development works continued across additional sites in Canada, the USA and Asia-Pacific, which have the potential to support up to an additional >1GW of aggregate power capacity capable of powering growth beyond the Company’s 795MW of announced power capacity.

Technical commentary

The Company’s average operating hashrate was 1,117 PH/s in July compared to 1,164 PH/s in June, with the Company’s operating capacity increasing to over 2.3 EH/s following the transition to the high voltage transmission network in early August as part of energization of the remainder of the first 50MW at Mackenzie. Power prices at Mackenzie are also expected to reduce by approximately 19% as a result of moving from the distribution feed to the transmission network.

The Company mined 154 Bitcoin during the month, a 4% increase from 148 Bitcoin mined during June 2022, which was primarily attributable to a decline in the average difficulty-implied global hashrate during the period plus one extra operating day in the month. The fall in the global hashrate suggests higher cost miners may have dropped out of the global Bitcoin network during the period, thereby allowing lower cost miners (such as Iris Energy) to increase their share of the network and Bitcoin mined.

The increase in electricity costs in July compared to June was primarily due to one extra operating day in the month.

* 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).
