Sweetwater 1 substation energization
Company: IREN - Project: Sweetwater 1
What the later record shows
Delivered on time
On the Q3 FY26 earnings call (transcript dated 2026-05-10, results released 2026-05-07), IREN said the Sweetwater 1 high-voltage substation had been energized 'on schedule', and later articles confirm it was energized earlier in 2026. No passage gives the exact date, and the February 10-Q had widened the target to Q2 2026, so it cannot be confirmed that energization was by 30 April rather than in early May.
