Physical capacity evidence
Whole-site registered total: 1020 MW, including retired units.
Registered capacity is the value retained in the committed BM-unit source snapshot. “Not retained” means the registry no longer supplied a positive figure; it does not mean the unit historically had no capacity. If a unit with a retirement event publishes a non-zero live declaration, the live declaration keeps it in the operating fleet pending review.
