Tillamook Windfloat - phase 1 Floating Wind Farm

30 Apr 2017: In  2008  Principle  Power  submitted  a  non‐solicited  proposal  to  the  TIDE  Hydrokinetic  Energy  Project RFP.   At  the  time,  the  request  for  proposals  did  not include  offshore wind  developments,  but  nevertheless,  TIDE  contacted  Principle  Power  for  more  information  about the WindFloat (previously called “MFWind”) technology and proposed development.  Following  this request, some interviews, and subsequent discussions, Principle Power and  TIDE  signed  a  Memorandum  of  Agreement  for  the  phased  development  of  a  150  MW  floating offshore wind power plant off the coast of Tillamook County, Oregon. The terms of  the MOA called for TIDE support in outreach activities hosted by Principle Power at public  meetings and  roundtable  discussions with  state,  federal, and local  stakeholders as well as  environmental  agencies,  fishermen's  associations  (such  as  the  Fishermen’s  Advisory  Committee  for  Tillamook  (“FACT”)),  and  commercial  and  recreational  marine  users  to  ensure that all stakeholder interests are considered.  Shortly  thereafter,  Principle  Power  and  Tillamook  PUD  also  signed  a  Memorandum  of  Agreement  for  the  same  phased  development. The  terms  of  the MOA  called  for Tillamook  PUD  and  Principle  Power  to  enter  into  good  faith  discussions  regarding  plant  location,  energy output and safe interconnection to the grid.  The utility and Principle Power agreed  that  they  could execute  separate Agreements  for  plant  ownership,  permitting,  community  outreach, environmental, energy production, grid‐interconnection, installation, deployment,  operations, maintenance, and/or other contracts and services as needed.
