Chesterfield - Tyler
It has become necessary to address an aging electric transmission line, which has been in operation for more than five decades, between our Chesterfield and Tyler substations in Chesterfield County. The rebuild will bring facilities up to current reliability and safety standards.
Overview
The portion of line proposed for rebuild is approximately 3 miles in length and runs parallel with other transmission lines within an existing corridor. Fiber and four transmission lines south of the Tyler Substation will also be replaced to current electrical and safety standards.
Benefits
- Maintains current right of way
- Complies with mandatory standards to ensure safety, reliability and to meet future needs
- Minimizes impact to the community and environment
- Replaces aging infrastructure
Community Engagement
At Dominion Energy, we are committed to keeping our neighbors informed about energy needs where they live and work. As the project develops, we will:
- Continue outreach by communicating with legislators, homeowners associations and other identified stakeholders
- Host a local open house to answer questions from residents and area businesses
- Provide ongoing communications through informational materials, mailings, email updates and a project website

FAQs
All proposed interconnections of electricity generation resources with a capacity of 20 megawatts or more are managed through a comprehensive process involving the generation owner, transmission owner, and regional transmission operator, PJM Interconnection. The process includes studies and analyses to identify grid impacts and facilities requirements driven by new renewable energy coming onto the grid by proposed generation resources. The renewable project developers may also build electric transmission infrastructure to connect the renewable generation resource to existing Dominion Energy grid infrastructure.
All elements of the electric grid are interconnected. New electric generators and energy-drawing sources in one area can impact elements of the grid in locations miles away. As part of the system impact and facilities studies for proposed generation sources discussed in the response to question one, the regional electric transmission grid is studied to determine where upgrades may be needed to maintain adherence with NERC reliability standards when the new facility comes online. In this case, in order to interconnect the Trowbridge Project, we need to rebuild Line 218 to maintain system reliability.
Costs for new and upgraded electric transmission infrastructure driven by generation interconnections, including renewables, are the responsibility of the generation owner (project developer).
SCC
The State Corporation Commission (SCC) is responsible for verifying the need, route, and environmental impact of transmission lines in Virginia. Documents related to the case are made available to the public on the SCC Docket Search section of the SCC website, in the "Search Cases" section (enter case number PUR-2020-00014). In addition, interested parties may also comment directly to the SCC by sending an email to sccinfo@scc.virginia.gov.
