The Northeast Ocean Data Portal is capturing the timelines of recent actions by the Federal Energy Regulatory Commission (FERC) related to permitting and licensing of marine hydrokinetic (MHK) projects via several layers in the Data Explorer. A MHK project is defined as a project that generates electricity from waves or directly from the flow of water in ocean currents, tides, or inland waterways. FERC is the agency with jurisdiction to issue licenses for MHK projects.

The Portal team assembles data and status information from FERC’s Hydrokinetic Projects information page.

In the Data Explorer, under Energy & Infrastructure > Planning & Permitting > Permitted Projects, users can activate two MHK project layers:

There is currently one licensed MHK project in the northeast region – the Bourne Tidal Hydrokinetic Test Site on the Buzzards Bay-side of the Cape Cod Canal. Portal users can click features in the map to view additional information:
