Evidence detail

Target: supply under contract started, 2028

Target restated October 2025: electricity to Microsoft by the end of 2028; Helion says it remains on track

A stated target, not something that has happened. It does not set a state. Targets can move; earlier and later ones are both kept.

“to provide electricity from the plant to Microsoft by the end of 2028, with Constellation Energy serving as power marketer. Having now secured the Conditional Use Permit for the site, Helion remains on track to meet that goal.”
