It is shown because two independent facts — turbine count and rated power — match the database exactly. Awaiting confirmation from a primary source.

From application to operation, this scheme took about 2 years.

What the register tells us

The application was determined in about 4 months. The scheme has been operating for about 23 years. At that age, wind farms commonly become candidates for repowering or life extension — nothing in the register confirms such a plan here. That works out at 1.3 MW per turbine on average.
