In a stormy January in Denmark, with 92% more wind across the country than in an average month, wind turbines provided 31.5% of national electricity consumption, or 1087 GWh of the 3446 GWh used. The electricity was generated by 5211 turbines with a combined installed capacity of 3123 MW. But it was far from a record. In January 2007, wind energy content through the month was 124% more than for a normal month, enough to provide the country with 35.5% of its electricity from 3135 MW of installed wind capacity, or 1225 GWh of 3409 GWh consumed. Despite the high volume of wind production in the early months of the year, it has not been necessary to constrain production from turbines at any time to maintain system stability, says Jens Møller Birkekær from Energinet.dk.
