Two Spanish firms hoping to test their 500 kW prototypes at Tarifa have been refused permission to install them. Both could be forced to seek sites elsewhere. Ecotècnia of Barcelona and Made of the national utility, Endesa, requested to install the prototypes at sites which already house their commercial turbines. "I imagine that [the refusal] has something to do with the moratorium," says Ecotècnia's Antonio Mart’nez, referring to the current freeze on development at Tarifa over environmental issues. He adds that it is unfair that Kenetech has been allowed to install 30 MW when he cannot put up one turbine -- a machine the company has high hopes of. Members of the communist-led Workers Commissions (CCOO), one of Spain's most powerful labour organisations, have stepped in to help Ecotècnia and held a meeting with environmental authorities, but so far to no avail. "It would be a great shame if we were forced to go elsewhere because Tarifa offers some of the best conditions for testing turbines," says Mart’nez.
