Oregon project aims for floating offshore turbine future

News, Ocean, Ocean energy, Wind turbines Add comments

After nearly five years of floating offshore wind farm planning off the coast of Maine, a project in Oregon may leapfrog those efforts.  An initial go-ahead from federal ocean regulators marks the starting line for a pilot project off Coos Bay, which will need to clear several more regulatory and financial hurdles before being built.  

Perhaps optimistically, Principle Power (the developer) is holding a target date of 2017 to have its initial five turbines operational.  These will be huge, 6MW, 600-foot turbines, similar in design to a model that’s already being tested in the water in Portugal.  The project is expected to cost $200 million, which would build around 100MW of capacity on land, as compared to the 30MW this pilot project will construct; Principle Power expects that steadier, stronger offshore winds will let these turbines operate at a higher capacity factor than onshore projects, partially making up that difference. Of course, experimental pilot projects are always far more expensive than later, full-scale build-outs; still, the financial feasibility of projects like this is a work in progress.
