Bulk Transmission Development in South Dakota
The South Dakota electric grid is part of the North American Electric Reliability Corporation’s (NERC) Eastern Interconnection. In South Dakota, the Midwest Reliability Organization is the regional entity, under NERC, charged with developing reliability standards and monitoring compliance for all owners, operators and users of the bulk electric system. South Dakota has two main balancing authorities: Midcontinent Independent System Operator (MISO) and Southwest Power Pool, RE (SPP). SPP is the primary balancing authority, while MISO monitors transmission systems in the north and northeast of South Dakota. Both SPP and MISO work together to centrally dispatch generation and coordinate the movement of wholesale electricity in South Dakota.
In South Dakota there are a number of investor-owned, independent, and cooperative transmission providers, including:
- Basin Electric Power Cooperative which serves south-central South Dakota;
- East River Electric Cooperative which serves eastern South Dakota;
- Rushmore Electric Power Cooperative which serves the western and central parts of the state;
- Otter Tail Power Company which serves the northern part of the state;
- NorthWestern Energy which serves eastern South Dakota along the James River; and
- Xcel Energy which serves eastern South Dakota.
