Hollydale Project

The Hollydale Project involves Xcel Energy rebuilding approximately 8 miles of existing 69 kV transmission line to 115 kV, constructing almost a mile of new 115 kV transmission line and building a new 115 kV substation – called the Pomerleau Lake Substation. Great River Energy will modify their Medina Substation to accommodate the project. The project is needed to address electric distribution concerns and to avoid feeder circuit overloads in the Plymouth area distribution delivery system. The project will provide increased distribution capacity in the Plymouth-Medina area. In response to Xcel Energy and Great River Energy’s request, the Minnesota Public Utilities Commission (PUC) granted a petition to withdraw the Certificate of Need and Route Permit applications for the Hollydale Project, with conditions and reporting requirements.
