What the evidence supports

That Helion Energy, the project's developer, published the quoted statement. It records "permission issued" for SEPA environmental determination (Mitigated Determination of Non-Significance) for the Malaga site; an environmental decision, not a construction or operating permit under permissions only.

What remains unknown

One permission is not every permission the project needs. Any permission beyond the action quoted. A construction authorisation is not an operating licence, and one authority's action is not another's.
