400 MW Wind Collection, Substation & Transmission Project

Capacity: 400 MW
Year Commissioned:  2019

RRC provided electrical services to a 400 MW wind project located in the Midwest. The facility consists of 163 Vestas V120 (2.2 MW) and 12 Vestas V112 (3.45 MW) wind turbine generators on sixteen (16) collector circuits split evenly between a North and South substation. When completed, the project will be the largest in the state. RRC’s scope included the transmission line design, substation design, SCADA system design, collector system, geotechnical work for the transmission line, and WTG foundation design. The 18-mile 345 kV transmission line is supported by engineered tubular steel poles with drilled pier foundations and direct embedment. The conductor arrangement is bundled. The design included full OPGW communication details. It is broken into two sub-sections with a substation in between. RRC and their partner provided the full construction package to procure and construct the line and provided construction support during construction.
