Great River Energy to upgrade its HVDC transmission system

USA, Minnesota: Great River Energy will soon complete a major upgrade to its HVDC transmission system which is made up of a 436 mile (702 km), 400 kV transmission line and two converter stations, one at Coal Creek Station and one at Dickinson Station near Buffalo, Minnesota. 

Great River Energy and ABB, the manufacturer of the utility’s high-voltage direct-current (HVDC) system, will complete the upgrade in spring 2019 during a planned 74-day HVDC system outage, reports T&D World.

The project will entail refurbishment of the critical components of the HVDC system, including replacement of all major components in the converter stations on either end of the transmission line

Great River Energy’s HVDC system delivers nearly all the power from the utility’s largest power plant, Coal Creek Station in Underwood, North Dakota, to Minnesota where its 28 member-owner co-ops are located.
