About Project

The Nebraska Public Power District (NPPD) is comprised of publicly owned facilities that provide energy to 84 of the state’s 93 counties and over a half million Nebraskans. Part of this energy resource is the hydro power facility located in North Platte. This facility generates power from both the North and South Platte Rivers. Since 1935, these rivers have provided hydroelectric power to the region. In the winter of 2021, Thomas Industrial Coatings earned the contract for the coating renovation of the pen stock at the hydro power facility.

The scope of work included containment, abrasive blasting, and applying a coating system to over 2,250 linear feet of exterior piping that traverses it way across the landscape outside of town. The non-incline pipe measured 13 feet in diameter while the incline pipe measured 9.5 feet. The total square footage of the project was over 117,000 square feet. Surface preparation for the project called for an SSPC SP6 Commercial Blast with a 1-3 mil surface profile. With an existing lead-based coating, coal slag with Blastox was used to encapsulate the hazardous material. The coating system applied was a three-coat zinc, epoxy, and urethane system.
