Wind

In June, the 2.3-MW Hywind facility, the world’s first large-scale floating wind turbine, was towed to a North Sea location with a water depth of about 220 meters (722 feet) and began operation. Over the next two years this turbine will be subjected to strong wind and waves in a harsh ocean environment in an effort to thoroughly test the innovative technology.

Renewable Generation in North America

Denmark in September inaugurated a 209-MW offshore wind park — the world’s largest to date — off the west coast of Jutland, in the North Sea.

Midwest Energy has a history of thinking and acting independently, especially since breaking away from the Rural Utilities Service almost 15 years ago. Two years ago, when its board of directors grappled with finding a balance between purchasing and generating electricity, it decided to construct its first power plant in 37 years. A matched set of nine 8.4-MW gas engines at Goodman Energy Center now provides efficient peaking electricity, improved overall system reliability, and backstop capacity for a 325-MW electrical system that features 16% wind power generation.

After months of preparation, Norway’s StatoilHydro and Germany’s Siemens in June erected the world’s first large-scale floating deepwater wind turbine some 7 miles offshore Karmøy, southeast Norway, on the 720-feet-deep waters of the Amoy Fjord. The developers are now gearing up to connect the Hywind turbine to the local grid, and it could begin producing power as early as mid-July.

The tension between the growing number of renewable energy projects and limited transmission capacity is reflected in Washington’s legislative agenda of establishing a national renewable portfolio standard and new transmission lines dedicated to moving renewable energy coast-to-coast. Even if those ideas become law, hurdles to the happy marriage of renewables and transmission remain.

Engineers at Purdue University and Sandia National Laboratories have developed a technique that uses sensors and computational software to constantly monitor forces exerted on wind turbine blades. Their achievement could one day improve the efficiency of wind turbines by providing the blades’ "smart" structure with necessary data to adjust to rapidly changing wind conditions.

Secretary of the Interior Ken Salazar, speaking in Atlantic City on April 6, added more hot air to the discussion about offshore wind when he stated that windmills off the East Coast could generate enough electricity to replace most, if not all, of the coal-fired power plants in the U.S. I’m disappointed Salazar didn’t take a few minutes for fact-checking and back-of-the-envelope ciphering before his speech.

Though Canada is rich in fossil fuels, nuclear power may fuel a significant portion of the nation’s future electrical generation needs, especially in provinces that have traditionally relied on hydropower and fossil fuels.

Turkey’s growing power market has attracted investors and project developers for over a decade, yet their plans have been dashed by unexpected political or financial crises or, worse, obstructed by a lengthy bureaucratic approval process. Now, with a more transparent retail electricity market, government regulators and investors are bullish on Turkey. Is Turkey ready to turn the power on?
