Abstract [en]

Wind power is expanding rapidly in Sweden. Increasing amounts of wind power sets higher requirements on balancing power and grid expansions and would affect the whole Swedish electricity system. The aim of this report is to examine the factors affecting the wind power expansion in Sweden. How many wind power plants projects will obtain building permissions and what costs and revenues can be expected? How much balancing power will be required and does a changing geographical distribution of the wind power plants reduce the need of balancing power?

A survey of the county board’s official applications has been made and out of all the applications, corresponding to 80 TWh produced per year, about half of the applications are expected to obtain a permit with a major portion of them located in the north of Sweden.

Especially older wind power plants, deriving revenue from Nord pool, find themselves today in a complicated financial situation. However new wind power plants with favorable wind conditions and with revenues from fixed prices are likely to be more commercially viable and less dependent on electricity certificates.

The power production can be expected to even out with a greater geographical dispersion and the balancing power requirement can be estimated to 60-80 % of the totally installed wind power. During short periods, of the order of hours, the power gain or loss is usually less than 10% but during longer periods, of the order of day, the wind power can in extreme cases experience losses and gains in power up to 70 % of the installed capacity.
