Columbia Power Technologies has selected Siemens Industry’s segmented rotary generator for use in Columbia Power’s utility-scale wave energy system, the StingRAY.
The patented, third-generation StingRAY is a floating, offshore wave energy system and represents the culmination of over 10 years of intensive, scaled development and testing. The megawatt-scale StingRAY delivers survivability with a competitive cost of energy and a low environmental impact.
“Our strategy was to choose a trusted global partner with significant expertise and experience. We wanted a company like Siemens that could provide a solution from existing technology, in order to reduce risk and shorten our commercialization timeline,” says Reenst Lesemann, Columbia Power Technologies’ CEO .
“Siemens will use its existing segment motor construction kit to design a generator for installation around the circumference of the buoy ultimately creating a built-in 7.5 m air-gap diameter motor/generator,” explains Razvan Panati, Director of Technology for Siemens Drive Technologies Division .
The initial generator, which will be able to deliver 1.5MW of peak power, will be tested at the National Renewable Energy Laboratory’s National Wind Technology Center in early 2014.
