High-Capacity Benefits
765 kV technology was identified in the MISO planning process as the preferred solution for the region, presenting several advantages:
- Efficiently carries large amounts of power over long distances while reducing overall project costs and reliably delivering electricity to customers throughout the region.
- Needs fewer transmission lines to carry the same amount of power.
- Requires fewer structures, reducing impact on land, communities and the environment.
- Provides additional capacity to power new manufacturing, homes, businesses and farms.
MISO’s analysis showed that one 765 kV transmission line can carry as much power as six 345 kV single circuit lines—minimizing the land needed by as much as 70-80%.
Structures
View the information below to see what the structures could look like in each segment.
North Rochester to Marion Segment
This is an example of a typical single-circuit 765 kV structure, similar to what could be used on the North Rochester to Marion segment.
MariBell Segment
This is an example of a double-circuit 765/161 kV steel lattice structure, similar to what could be used on the MariBell segment.
