• Are there ways to make the towers less reflective, i.e. less visible?
  • Galvanized steel lattice towers are the preferred structure type for the project. The tower configuration is open and airy and allows the eye to look through and beyond the structure to objects in the background. Typically, the dull finish of the galvanized steel is muted against a variety of backdrops, whether against a hillside, forested land, or even the sky. Painted structures appear even more unnatural and often draw more attention than galvanized structures.

    Some locations, however, do require the use of other structure types to minimize visual and resource impacts. H-Frame structures, which consist of two tubular steel poles and a cross arm, may be used in some areas where shorter spans can be utilized or are necessary. H-Frame structures will have a weathering steel finish, which mimics the visual characteristics of a standard wood pole.

  • Would local companies be able to bid on various aspects of project construction?
  • Yes. For vendor and contractor information, click here.

    Idaho Power service territory: Included in Idaho Power’s Requests for Bids are specific criteria and qualifications that must be met in order for a bid to be valid. These qualifications include being able to demonstrate experience related to constructing projects of similar scope.

    Currently, Idaho Power’s transmission system consists predominantly of 69 kilovolt (kV) to 345 kV facilities. Idaho Power’s planned 500 kV projects, Gateway West and Boardman to Hemingway, are the first 500 kV facilities proposed by the company. Since there have not been projects of this magnitude built in Idaho for over 30 years, most local contractors do not have the experience or equipment necessary to construct 500 kV facilities.
