The corporate vehicle of Aapua Vind AB serves as the primary operator and owner, managing the day-to-day operations and strategic decisions for the 9.9 MW facility.
Land Rights and Sveaskog
While Aapua Vind AB holds the ownership of the wind farm assets, the land on which the turbines are situated is owned by Sveaskog. Sveaskog is described as Sweden's largest forest owner and is a state-owned enterprise. The wind farm operates on land owned by Sveaskog, implying a lease or land-use agreement between the private owner of the wind farm and the state-owned forest company. This arrangement is common in Sweden, where significant portions of the land are under the control of large forest companies, and renewable energy developers must secure land rights through leases or concessions. The land use for wind energy production coexists with the primary function of the landowner, Sveaskog, which manages forest resources. The specific terms of the land lease agreement, such as duration, rent, or land area, are not explicitly detailed in the provided grounding, but the relationship is defined by the operation of the wind farm on Sveaskog's property. This partnership allows for the utilization of land in a relatively remote area of Sweden, contributing to the energy infrastructure of Norrbotten County.
Technical Specifications
The Aapua Wind Farm utilizes seven Vestas V82-1.5 MW Arctic turbines to generate electricity. These specific turbine models were selected for their performance in the northern Swedish climate, contributing to the facility's status as the northernmost wind farm in Sweden as of 2007. The installation is situated on land owned by Sveaskog, the state-owned forest company, which provides the necessary terrain for the wind infrastructure southwest of Aapua in Övertorneå municipality.
Turbine Configuration
The technical core of the wind farm consists of seven identical units. Each turbine is a Vestas V82-1.5 MW model, designed with an 82-meter rotor diameter. This rotor size allows for efficient energy capture in the variable wind conditions typical of the Norrbotten County region. The nacelle height for each unit is 78 meters, positioning the rotor hub at an optimal elevation to maximize wind shear benefits. The combined output of these seven units results in a total installed capacity of 9.9 MW.
