Sweetwater 1,400MW energization April 2026
Company: IREN
What the later record shows
Delivered; the record does not say when
September 2026 articles say IREN energized the Sweetwater 1 high-voltage substation 'earlier this year' (2026). None gives the date, so it cannot be told whether this met the April 2026 target.
“We are targeting a substation energization date of April 2026 and late 2027 for Sweetwater 1 and Sweetwater 2, respectively.”
