Flowing water contains large amounts of usable energy. Beyond traditional dam-based hydroelectric generation, water’s power can be captured using hydrokinetic technology. A hydrokinetic project generates electricity from moving water: the flow of tides, waves, ocean currents, or unimpounded rivers. Most hydrokinetic projects will need regulatory approval from the Federal Energy Regulatory Commission, a process that is still evolving but is getting easier over time.
Technology continues to evolve rapidly, and each new design has to be tested. Under limited circumstances, developers can test turbines without obtaining a FERC license. In 2005, dealing with Verdant Power’s testing of underwater turbines in the East River in New York City, FERC ruled that a license is not required for a hydrokinetic project if the technology is experimental; the proposed facilities will be used for a short period for studies needed to seek a license; and the power generated from the test project will not be transmitted into, or displace power from, the electric grid.
This opportunity to test turbines without a license is limited. Most hydrokinetic projects will need to get FERC approvals such as a preliminary permit, license, or exemption from licensing. Tomorrow, I'll look at some of those paths toward developing and operating a renewable hydrokinetic energy project.
