CapX2020 Bemidji to Grand Rapids Transmission Line
A new 230 kilovolt (kV) transmission line has been built that stretches about 70 miles between Bemidji and Grand Rapids, Minn. At HDR, we combined a team of environmental, regulatory compliance and engineering specialists to help move the project forward through major milestones. The transmission line is part of the CapX2020 joint initiative, which is the largest regional transmission development in the Upper Midwest in nearly 40 years.
- Planning, siting and permitting. We assisted in the development of permit applications and NEPA documentation for the state of Minnesota, Chippewa National Forest and the Rural Utility Service (RUS). Siting information for five corridors was managed through a Geographical Information System. Three routes were later identified through the scoping process where a more detailed GIS analysis was presented. Extensive botanical surveys and specialized cultural resources studies were executed.
- Engineering and design. Construction sequencing, detailed design, and sensitivity to public lands and the various biological and cultural resources were considerations during design and construction phases of the project. We prepared surveying and engineering deliverables and line drawings; conducted transmission line modeling; and designed foundations.
- Environmental Monitoring. We performed environmental compliance monitoring during construction.
This integrated approach, along with ongoing coordination with permitting agencies, provided a solid basis to obtain permits in a timely manner enabling construction to proceed on schedule.
