Evidence assessment
What the public record supports, without upgrading incomplete claims.
B2 contractual evidence
A Master Plant Development Agreement governs a fleet of projects, but only the separate 50 MW Hermes 2 implementation has a disclosed binding PPA.
Optioned MW excludes the separately listed 50 MW Hermes 2 PPA to prevent double counting against the 500 MW fleet ceiling.
Record history
Milestones remain visible when later evidence supersedes them.
