In 2000, Middelgrundens Wind Farm was established just 3.5 km offshore from Copenhagen harbour. Consisting of 20 turbines with a capacity of 2 MW each, it was established with 50% of the ownership held by the local utility, which is owned by the City of Copenhagen. The other 50% is owned by Middelgrundens Vindmøllelaug I/S. Each share, sold for 4,250 DKK (€567), corresponds with 1/40,500 ownership of the partnership, representing production of 1,000 kWh per year. In the beginning, membership was limited to residents from the municipal area, however, legislative changes required opening of membership, and now anyone is eligible to become a member.
