Up to 1400 MW of wind can be taken on to the grid in Schleswig-Holstein without the need for major high voltage cable construction, according to the Schleswig-Holstein energy ministry. Pinpointing the physical limits of the grid, however, has been a constant subject of dispute between potential wind operators and utilities. Thus, the ministry and the region's main utilities have commissioned a study from the University of Dortmund to analyse available grid capacity. The experts will also investigate the effects of increasing or decreasing wind capacity at any given point on the grid. Feed-in management of wind power -- operating wind plant at less than maximum output -- will also be examined.
