COVID doesn’t stop Lazy Dog and Gateway substation construction for Tri-State in Denver

Completed in January 2020 by Energy Erectors, the Weld County, Colo., Gateway Substation is a new 230/115/12.47-kV facility.

Energy Erectors announced last week that it has completed civil construction of two substations for Denver, CO., Tri-State Generation & Transmission Association. Tri-State hired Energy Erectors to undertake the substations’ site preparation, complete the foundation, install security measures, pull cable, handle bus work and wire breakers and transformers.

The first of the substations, completed in January 2020, is the 230/115/12.47-kV Gateway Substation, in Weld County, CO, which includes a 230-kV three-breaker ring bus, expandable to a future breaker-and-half configuration and one 230/115-kV, 150 MVA transformer. The second project is the new 115/13.2-kV Lazy Dog Substation.

According to Jeffrey Lines, Transmission Construction manager for Tri-State, the Lazy Dog project encountered delays related to permitting, weather and COVID-19, but Energy Erectors was able to complete the site work, so Tri-State could complete the steel erection and commissioning.

“When our Gateway project ran into a delay related to getting two transformers, Energy Erectors showed its flexibility by working around those deliveries, putting in conduit across the yard, grading the site,” said Lines, “and making it possible to meet our commissioning deadline.”
