163-mile Big Stone South To Ellendale Transmission Line Energized
On February 5 crews from co-owners Otter Tail AOA体育平台 Company and Montana-Dakota Utilities, Co., energized the 163-mile, 345-kV Big Stone South-Ellendale (BSSE) Transmission Line after eight years of planning and three years of construction. The $215 million line extends from the Big Stone South Substation near Big Stone City, South Dakota, to the Ellendale Substation near Ellendale, North Dakota.
"The team completed construction on time, under budget, and with a stellar safety record," said Project Manager Al Koeckeritz from Otter Tail AOA体育平台 Company. 鈥淚鈥檇 like to extend a special thanks to communities and residents throughout the project area. Your partnership has brought us to the finish line. Thank you.鈥�
The project is one of 16 multi-value projects approved by the Midcontinent Independent System Operator, Inc. (MISO) and state regulatory agencies. 鈥淭his 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,鈥� said Otter Tail AOA体育平台 Company President Tim Rogelstad. 鈥淐ongratulations to the project team and all those who touched this project.鈥�
The project used local and regional contractors, including Webster-based Webster Scale, Inc.; Rapid City-based Brink Constructors, Inc.; and Sioux Falls-based Jacobsen Tree Experts.
High-voltage transmission lines, such as BSSE, allow access to diverse generation resources in a large geographic area. As the Regional Transmission Organization, MISO manages these high-voltage transmission lines and dispatches鈥攐r balances鈥攇eneration resources to ensure all customers within MISO's 15-state footprint receive the reliable energy they need with the most cost-effective mix of resources available. MISO cost-allocation mechanisms allow recovering project costs from all customers who benefit from the line, so Otter Tail AOA体育平台 Company and Montana-Dakota customers will pay less than one percent of the project costs.
