Peshastin Pinnacles Transmission Line Upgrades

What

Chelan PUD will upgrade the transmission line that runs through the Peshastin Pinnacles State Park to provide better access, protect structures from fire, and maintain reliable electrical service. Working with members of the Confederated Tribes of the Colville Reservation, state parks officials, other agencies and neighboring landowners, Chelan PUD identified a new route for the poles, to run behind and around the park.

What to Expect

  • Transmission poles will be upgraded from wood to steel to protect them from fire.
  • A portion of the line will be rerouted to below the Pinnacles rock formations (see map).
  • To ensure compliance with regulatory requirements for clearance, some poles may be slightly taller than existing poles.
  • Construction will begin in June 2020, and continue through November, with a brief break in work from August through September.
  • During construction, Peshastin Pinnacles State Park will be closed to the public. For updated information about park closures, please visit the Washington State Parks website.
