Line upgrades of the LRS – Ault and LRS – Wayne Child 345 kV lines will be necessary, as well as capacitors at Dalton substation near Sidney. This project will also establish a 34.5 kV point of delivery for High West Energy’s proposed 34.5-12.5 kV, 20 MVA substation contained within State’s proposed Wayne Child 345-230 kV substation. The project is planned to be completed in the 4th quarter, 2017, and is in Phase III of the WECC Three Phase Rating Process.
