The register also records a planning permission expiry in Dec 2011, in the same month as, or before, the permission was granted: it refers to an earlier permission, 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.

What the register tells us

The application was determined in about 25 months. A planning permission on this site expired in July 2019. The scheme has been operating for about 14 years. That works out at 0.85 MW per turbine on average.
