Overview

Dominion Energy currently operates 115 kilovolt (kV) electric transmission lines that provide critical electric service from Yorktown to Peninsula and serve Seaford Substation in York County, Newport News City and Hampton City, Virginia.

The existing 115 kV electric transmission lines were built in this corridor using double circuit 3 pole wood H-frame structures in 1957. We will rebuild the existing electric transmission line with double-circuit 115 kV brown weathering steel monopole structures in accordance with current electrical and safety practices.

The new double-circuit, brown weathering steel monopole structures will be located near each existing structure, just outside the existing footprint. The existing structures will be removed, and the foundations will be demolished just below grade.
