Construction on the Albemarle Sound crossing was completed and energized on December 5, 2012.
Dominion completed a rebuild project involving replacement of an existing transmission line that crosses the Albemarle Sound. These improvements will increase service reliability and provide for projected growth in demand for electricity.
Following the extensive damage caused by Hurricane Isabel in 2003, Dominion made immediate repairs and upgrades to the area’s electric transmission infrastructure. The rebuild of the transmission line between the Winfall Substation in Perquimans County and the Trowbridge Substation in Washington County is nearing completion.
The final phase of the project required replacement of the 5-mile segment crossing the Albemarle Sound, and it was completed on December 5, 2012. New foundations and structures were installed on the same centerline as the previous line, and the old structures were removed and the foundations were cut off below the sub aqueous grade line. Dominion partnered with federal, state and local agencies when developing the construction plan for this project.
State law exempts a utility from having to apply for a Certificate for Public Convenience and Necessity (CPCN) if the line is being replaced by a similar one in substantially the same location, so a CPCN was not required for this revised project.
The North Carolina Utility Commission (NCUC) is responsible for determining the need, route and environmental impact of transmission lines in North Carolina. Because state law exempts a utility from having to apply for a Certificate for Public Convenience and Necessity (CPCN) if the line is being replaced by a similar one in substantially the same location, a CPCN not required for its revised project.
Additionally, six substations between Winfall and Trowbridge will need to be converted before increasing the operating voltage from 115kV to 230kV. Dominion will seek input and any necessary approvals from the localities impacted.
