The Spanish government is understood to be considering amendments to the current wind off-take tariffs after contacting the country's major energy companies over the issue.

The government is thought to want to change the current arrangements that allow wind companies to sell output at a fixed rate of €65/MWh or at the spot market price plus a premium. With spot prices soaring, the government is considering requiring wind generators to sell into the regulated market at the fixed price only from 2006.

Wind players consider such a move to be retrogressive given the move could cut €450 million from revenues, but the measures would improve government deficits.
