Sweetwater 1 energization April 2026
Company: IREN - Project: Sweetwater 1
What the later record shows
Delivered; the record does not say when
By May 10, 2026, IREN said the Sweetwater 1 substation had been energized 'on schedule'. By then the target had been restated as Q2 2026, so whether it met the original April 2026 date is unknown.
