The Cunningham-Dooms Project replaces the high-voltage line between the Cunningham and Dooms substations that was placed into service in the 1960s. This line is nearing the end of its useful life and needs to be replaced with new equipment to meet current standards.
May 2020 – Right of way restoration and removal of temporary access roads continues with anticipated completion by the end of 2020.
April 2019 - Phase 3 construction is complete and the project is fully constructed and energized. Rehab and restoration activities will continue through the end of 2019.
- Help strengthen the electrical grid
- Replace aging infrastructure
- Ensure reliable electric service for the customers consistent with North American Electric Reliability Corporation reliability standards
- No new right of way is required.
- November 2017 - Phase 1 construction begins in Fluvanna County.
- May 2018 - Phase 1 construction and rehab completed.
- November 2018 - Phase 3 construction started in Albemarle and Augusta counties.
- February 2019 - Phase 2 construction completed. Rehab activities ongoing.
- April 2019 - Rehab and restoration activities are underway.
- May 2019 - Line construction is completed.
Need & Description
- As approved by the State Corporation Commission (SCC), the galvanized lattice structures will be chemically pre-dulled to mute the finish of the galvanized sheen. The conductor (line) will be dulled to mute its reflectivity.
- Approximate total line length is 33 miles.
- Typical structure description – The existing 500kV structures average 106 feet tall with a range from 72 feet to 149 feet. The preliminary approximate heights of the proposed towers range from 108 feet to 174 feet with an overall average height of 134 feet over this 32-mile rebuild project. Compared to the existing structures, the increase in average height is 28 feet. View existing and proposed configurations below:
- Section #1 – 0.8 mile*
- Section #2 – 1.2 miles*
- Section #3 – 2 miles*
- Section #4 – 18.9 miles*
- Section #5 – 9 miles*
- Section #6 – 0.7 mile*
* Preliminary engineering, as of February 8, 2016
