Puget Sound Tidal Power (PSTP) has been re-organized as two new companies,

Hydrovolts, Inc.

Grays Harbor Ocean Energy Company LLC.

During 2007 PSTP conducted the
Tacoma Narrows Tidal Power Feasibility Study
for the City of Tacoma, Washington.

The project team had the following accomplishments:

  • Development of a 3-D dynamic tidal current model that allows fast and accurate analysis of power density for exact determination of the best sites for turbines.  This model can be applied to any coastal site in the world with reasonably accurate bathymetric data for the site.

  • Validation of the model using Acoustic Doppler Current Profilers deployed at three stations in the channel;

  • Realistic and verifiable determination of the actual amount of renewable energy that can be produced by tidal turbines throughout the entire year and all tidal cycles;

  • Survey of all turbine developers who could be contacted and comparative analysis of the designs and potential effectiveness;

  • Design of a new hydroacoustic monitoring systems for turbine arrays to detect fish and other objects in the turbine field, useful for both baseline condition assessment and for real-time monitoring of turbines;

  • Invention of a new ducted turbine design that is more efficient that other designs and also safe for fish and marine mammals;

  • Invention and design of a floating platform for easy deployment of full-size turbines to be tested in the current below the platform;

  • Comprehensive environmental and other permit analysis including costs and schedules;

  • Comprehensive economic analysis incorporating regulatory and market scenarios;

  • Development of a strategy for ongoing funding of tidal power demonstration projects;

  • Delivered the final report to the client on time and on budget.

Our new company, Hydrovolts Inc., will provide in-stream turbines
for renewable power generation around the world. 
Hydrovolts is also developing a major offshore wind/wave energy project.
