One-fourth of 375 wind turbines built in Denmark in 1999 cannot be classified as "previously existing" and do not qualify for the old premium tariff under the Danish wind market transition to green certificate trading, applicable to turbines built before January 1, 2000. So rules the Danish energy agency in its investigations of fraud levelled by a small citizen's action group against developer Jysk Vindkraft. The group claims the developer used a loophole in the regulations to gain a higher rate of payment for its projects than it was eligible for (Windpower Monthly, November 2000). Jysk Vindkraft is behind 80 of the 99 rejected turbines. Jens Leth of the company says its contracts have been interpreted incorrectly and believes the turbines can be re-classified as "existing" when the energy agency hears its arguments.
