Canal Flats update (0.8 EH/s, 30MW capacity) – BC, Canada
Canal Flats has been powered by 100% renewable energy since inception4.
The project achieved average monthly operating hashrate of 825 PH/s in July compared to 831 PH/s last month.
Mackenzie update (2.6 EH/s, 80MW capacity) – BC, Canada
Mackenzie has been powered by 100% renewable energy since inception4.
The project achieved average monthly operating hashrate of 2,583 PH/s in July compared to 2,572 PH/s last month.
Prince George update (1.6 EH/s, 50MW capacity) – BC, Canada
Prince George has been powered by 100% renewable energy since inception4.
The project achieved average monthly operating hashrate of 1,592 PH/s in July compared to 1,608 PH/s last month. During the month, the team conducted scheduled maintenance at Prince George (reliability testing of the 25kV cables between the substation and switchgear occurred on July 12-13).
Childress update (0.6 EH/s, 20MW operating / 80MW under construction) – Texas, USA
Childress has been powered by 100% renewable energy since inception via the purchase of RECs.
The project achieved average monthly operating hashrate of 562 PH/s in July compared to 577 PH/s last month.
The data center at Childress successfully maintained stable hashrate at intake temperatures of up to ~111°F (~44°C) (see chart below), further validating the Company’s industry-leading proprietary air-cooled data center design.
The Company’s ability to operate in Texas through extreme temperatures demonstrates the quality of our proprietary data centers, allowing us to enhance the operating environment of our hardware (and thereby extend asset life). This also provides true optionality to transition between mining Bitcoin and energy trading to optimize profitability, in contrast to operators who may be forced to curtail at high temperatures regardless of energy market conditions (i.e. due to operational limitations).
Childress: Hashrate vs. Intake Temperature chart is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/80970e50-c5a4-4c2a-8c06-6df2fdc40e3e
Construction of the remaining 80MW is underway for Phase 1 (first 100MW), with civil works scheduled to commence in August.
The Company’s significant upfront investment in key infrastructure also provides a rapid, efficient and near-term growth pathway for the subsequent 500MW of 600MW power capacity at the site.
Canal Flats is pleased to advise it has renewed its sponsorship of the Columbia Valley Rockies Hockey team for the 2023/2024 season. A sponsorship of C$10,000 will go towards supporting the local youth for what is looking to be another exciting hockey season.
Applications have now closed for the 2023 Community Grants Programs for Mackenzie and Prince George. The Company is currently reviewing submissions and successful recipients are expected to be announced in the coming months.
Applications are currently being accepted for the 2023 Community Grants Program for Childress, with Iris Energy to invest up to US$100,000 into local non-profit organizations in the community.
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 capacity that can power growth beyond the Company’s 760MW of announced capacity.
Operating and financial results
Daily average operating hashrate chart is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/bb12d311-6313-4d48-9ad8-a6e153a7c689
The Company’s average operating hashrate was 5,562 PH/s in July (compared to 5,587 PH/s in June) with the marginal decrease primarily attributable to scheduled maintenance at Prince George (reliability testing of the 25kV cables between the substation and switchgear occurred on July 12-13). The decrease in Bitcoin mined (423 vs. 428 in June) was primarily attributable to a decrease in network transaction fees and an increase in network difficulty. The increase in electricity costs per Bitcoin ($15.5k vs. $13.0k in June) was primarily attributable to higher prices at Childress (typically higher during summer months) and reduced market volatility (lower energy trading proceeds), noting the Company retains flexibility to reduce future power costs through adjusting miner output in response to changes in mining economics.
