Basin Electric's generating portfolio is diverse, including coal, wind, renewable, nuclear and natural gas. And in the next couple years, it will include another natural-gas fired power plant in northwest North Dakota. Basin Electric is also studying the need for a new transmission line in northwest North Dakota.
Mike Risan, senior vice president of Transmission, talked about the load growth in western North Dakota. "One of the challenges is projecting the growth and identifying what transmission additions Basin Electric needs to make to provide power to our member cooperatives in that part of the system," he said.
Basin Electric is planning to build a 345-kilovolt transmission line around the western end of Lake Sakakawea, from Antelope Valley Station to Williston to Tioga. "At this point we’re basically playing catch-up since the load has developed so quickly," he said. "As we move forward, we are addressing the issue with a phased approach to avoid the possible risk of overbuilding the transmission system in the event the rate of growth diminishes."
A preconference session addressed the complicated issue of whether or not Basin Electric should join a regional transmission organization (RTO) to access energy markets. It would be a fundamental change in the way the parties to the Integrated System do business, and how that change will affect members is unknown. The Integrated System is a transmission system owned by Basin Electric, the Western Area Power Administration and Heartland Consumers Power District.
The eight panelists included representatives from Basin Electric, Integrated System owners, member cooperatives, and a generation and transmission cooperative that already joined an RTO.
Wayne Backman, Basin Electric senior vice president of Generation, said RTOs provide reliability, dispatch generating resources economically and plan transmission enhancements jointly. "We've always jointly planned transmission with our neighbors to avoid duplication of services. RTOs simply do it in a larger footprint."
Mike Risan, Basin Electric senior vice president of Transmission, said the cooperative's options include status quo, full RTO membership, or a hybrid model of membership, where some generation and some load is placed within an RTO's footprint. Basin Electric is participating in the Midwest Independent System Operator’s market by placing some generation in their footprint. "Unless there is a compelling reason to join, we should stick with the hybrid model. It buys us some time to analyze the risks associated with full membership," he said.
