One of the United States' energy giants has bought in to a small renewables company in southern Sweden to build an offshore wind farm. Cinergy Corp (annual turnover $5.9 billion) says it has signed a development agreement through its subsidiary, Cinergy Global Power Inc, with Renewable Energy AB of Malmö. The $100 million installation at Skabbrevet in the Öresund, the sound between Denmark and Sweden, is meant to be the first of at least five joint developments. Annual production at the site, several kilometres off the coast between Landskrona and Barsebäck, will be about 266 GWh, enough to supply more than 50,000 households, the company reports. Cinergy Corp of Cincinnati, Ohio, describes itself as "one of the largest non-nuclear electrical power suppliers in the USA... [with] a strong interest in renewable energy sources" and with wind power investments in Spain and Portugal as well as the US.
