The CapX2020 Monticello-St. Cloud 345 kV transmission line in Minnesota has been energized, Xcel Energy has announced.
The 28-mile segment between the new Quarry Substation near St. Cloud, Minn., and the existing Monticello Substation is the first CapX2020 project to be completed and placed in service.
The Monticello-St. Cloud project is double-circuit-capable, which allows for future capacity expansion on the existing structures. To reduce land impacts, single-pole steel structures were predominantly used, with the poles spaced about five per mile, according to Xcel Energy.
‘The project ensures service reliability and provides capacity for new power generation outlets, when needed, and brings lasting benefits to the Upper Midwest,’ says Will Kaul, vice president of transmission at Great River Energy, one of 11 investor-owned, cooperative and municipal utilities in Minnesota and the surrounding region that are involved in the CapX2020 transmission project.
Construction is expected to begin early next year on the Fargo, N.D.-St. Cloud 345 kV project, and construction on the Brookings County-Hampton 345 kV project in Minnesota is scheduled to start in April 2012.
Construction started on the Bemidji-Grand Rapids 230 kV project in Minnesota earlier this year and is expected to be complete in late 2012. Regulatory permits for the Hampton-Rochester-La Crosse 345 kV project in Wisconsin are pending with state and federal agencies.
