how do they work
How Do They Work?
  • TISEC Devices are designed Similar to Wind Farms using Tidal Currents to power the turbines.
  • Three Basic designs for the turbines.
  • Four Types of Anchoring Systems.

    • Salmon Migration
    • Marine Mammal Migration
    • Bottom Fish Habitat
    • Shellfish
    • Migratory Birds
    • Reduced Current Velocity
    • Fish Harvests (Commercial, Recreational, Ceremonial and Subsistence)

Tribal Treaty Reserved Rights
  • Right to harvest fish and Usual and accustomed stations.
  • Right to protect fish habitat.
impacts to planning processes
Impacts to Planning Processes

How would development of these projects affect planning processes?

  • Salmon Recovery Plans
  • Orca Recovery Plans
  • Bottom Fish Recovery Plans
  • Oil Spill Containment and Clean-up Plans
  • Puget Sound Partnership Recommendations
  • Salmon Management Plans
summary
Summary
  • The Technology is new and experimental.
  • Potential benefits may offset other environmentally damaging sources.
  • Potential affects to natural resources are currently unknown, but could be severe.
  • Development of these projects may limit access to areas for harvests).
  • New Information needs to be developed to adequately balance the benefits vs. impacts.
  • Website developed as a clearinghouse for information. http://pstidalenergy.org
