The Federal Energy Regulatory Commission and the Interior Department’s Bureau of Ocean Energy Management revised federal guidelines July 19 to clarify the regulatory process and hasten development of marine and hydrokinetic projects. The new guidelines replace others issued by the Minerals Management Service and the commission as part of a 2009 memorandum of understanding that sorted out their jurisdictional authority over projects. Industry representatives are cautioning that the guidelines for developers of wave, tidal, and ocean-current energy projects on the Outer Continental Shelf will likely do little to help the nascent industry. The Energy Department’s water power program was appropriated $58 million in 2012, but the funding has been spent mostly on theoretical studies. Industry studies indicate that the technologies may provide 10 percent of the country’s electricity.
