The register also records a planning permission expiry in Jul 2019, after commissioning: an administrative date with no effect on the operating wind farm, left off the axis.

DevelopmentConstructionOperationAhead (repowering horizon at 22 years)

From application to operation, this scheme took about 6 years.

The register links a second scheme on this site (REPD ref 4194, Operational): 6 turbines · 2 MW each · applicant REG Windpower. Two schemes on one site usually mean a repowering or an extension — to be confirmed with the operator.
