The Swedish Energy Agency (STEM) has pledged some SEK 2.3 million to Gotland based Siral System Co AB to cover 10% of the cost of a proposed wind plant extension on the island at Näs. The grant will help update ageing turbines and increase capacity to 2 MW, according to Siral's Thomas Sirland. The handout is part of the government's commitment to increasing electricity production from wind power to 10 TWh in the next ten to 15 years. The grant is among the final subsidies being granted from a pool of SEK 300 million of government money for wind development. Capital subsidies are being replaced by a mandate for green power, facilitated by trade in green power certificates. Siral System was formed in 1965 and operates 70 turbines on Gotland -- half the island's wind power capacity -- and has interests in projects elsewhere in Sweden. It is also looking at projects further afield in the Baltic area.
