In tomorrow's liberalised electricity market, utilities would in all probability not be allowed to limit the amount of wind power they take onto their grids. As a result, fears that a proposed 5% cap on wind penetration would stymie future wind growth are now fading. Nonetheless, the German wind station operators organisation, Wirtschaftsverband Windkraftwerke (WVW) in Hannover has commissioned an expert to look into the legality of the proposed cap on the uptake of renewables-generated power by utilities (Windpower Monthly, December 1997). The cap is an amendment to the law governing the German wind industry's Renewable Energy Feed in Tariff, included as part of liberalisation legislation. The legislation places a 5% cap on renewables "at each level of power supply" through the utility hierarchy -- from the local utility though the supra-regional power company. WVW argues that since consumers will be free to purchase power from whom they choose, there will no longer be a limited chain of utility supply.
