Otter Tail Power on March 21 said that its crew and Montana-Dakota Utilities’ crew on Feb. 5 energized the $215m, 163-mile, 345-kV Big Stone South-Ellendale (BSSE) Transmission Line after eight years of planning and three years of construction.
Otter Tail Power and Montana-Dakota Utilities co-own the project, according to the statement.
The line extends from the Big Stone South substation near Big Stone City, S.D., to the Ellendale substation near Ellendale, N.D., Otter Tail Power said.
Al Koeckeritz, Otter Tail Power project manager, said in the statement, in part, "The team completed construction on time, under budget, and with a stellar safety record."
The project – which used local and regional contractors, including Webster Scale, Inc., Brink Constructors, Inc., and Jacobsen Tree Experts – is one of 16 multi-value projects approved by the Midcontinent ISO (MISO) and state regulatory agencies, Otter Tail Power said.
Otter Tail Power Company President Tim Rogelstad said in the statement, in part, “This portfolio was designed to improve reliability of the electric system and increase system capacity to address growth in demand, support public policy by enabling renewable energy to be integrated into the system, and boost regional economies by creating jobs, supporting local businesses, and contributing taxes.”
As TransmissionHub reported, construction began in summer 2016 on the project, which is designed to improve reliability of the regional power system; increase system capacity to address growth in regional demand; support public policy by enabling renewable energy to be integrated into the system; and boost regional economies by creating construction jobs and supporting local businesses.
