Proposed Plan to Replace Aging Transmission Structures

Dominion plans to rebuild a segment of an existing 500 kilovolt (kV) electric transmission line that crosses the James River. The line serves Charles City and Prince George Counties as well as the surrounding areas. The transmission line was placed into service in the 1960s and several structures have significant steel deterioration and have reached the end of their functional life.

Dominion will replace four transmission structures. Two existing Cor-Ten steel structures in the water will be replaced with two similar galvanized steel structures of the same height. The new structures in the water will be supported by the existing foundations– minimizing underwater disturbance. Two existing Cor-Ten steel anchor structures – one on either side of the shore – will be replaced with two galvanized steel A-Frame structures. The new structures on the shore will be approximately 15 feet taller than the existing structures.
Construction on the new transmission line is proposed to begin summer 2017 and will be completed late 2017.

Dominion’s rebuild project will:
- Replace aging infrastructure
- Maintain continued reliable service to local customers
- Help strengthen the electrical grid
- Require no new right of way
- Require no new foundations in the river
