Natural Gas

Distribution in OH, WV and Western States

Natural gas reaches 1.3 million customers in Ohio and West Virginia over a huge network of gas distribution pipelines via Dominion Energy Ohio and Dominion Energy West Virginia, our regulated natural gas distribution companies. In Utah, southwestern Wyoming and southeastern Idaho, Dominion Energy provides retail natural gas distribution service to more than 1 million customers. Dominion Energy Wexpro develops and produces gas reserves on behalf of Dominion Energy, with operations in Wyoming, Colorado and Utah.

Distribution in the Southeast

Dominion Energy maintains approximately 12,440 miles of natural gas pipelines in North Carolina and approximately 10,330 miles in South Carolina, providing natural gas service to a combined 1 million customers in both states. 

Transportation and Storage in Western States

Transportation and underground natural gas storage services are provided in Utah, Wyoming and Colorado by our interstate natural gas pipeline company, Dominion Energy Questar Pipeline, LLC. It owns and operates slightly more than 2,500 miles of pipeline. The sale of the company's gas transmission and storage assets to Berkshire Hathaway Energy, is expected to be completed in early 2021.

Status and Health of the Natural Gas Infrastructure

Electricity

Dominion Energy's 6,700-mile network of regulated electric transmission lines and 58,510 miles of distribution lines enables us to move electricity to 2.6 million homes and businesses in Virginia and North Carolina. We also have over 30,000 miles of regulated electric distribution lines in South Carolina, providing electricity to more than 764,000 customers in that state.

Electric Projects and Upgrades

Dominion Energy plans to meet increased demand for electricity through a balanced program of program of initiatives. These include new and upgraded generating facilities to meet peak demand, and improvements to the electric transmission and distribution system.

Status and Health of the Nation's Electrical Systems

The U.S. electric grid is a complex network of independently owned and operated power plants and transmission lines. Aging infrastructure and a rise in domestic electricity consumption is forcing experts to examine the status and health of the nation's electrical systems. Several media and information sources have produced intriguing materials about the nation's power grid:

  • National Public Radio published a ten-part series of stories on NPR.org, examining the costs, the politics and other challenges of upgrading the country's electricity grid.
  • Virginia Energy Sense is an information source for the Commonwealth of Virginia designed to assist citizens seeking ways to lower their monthly energy bills. Our energy use is growing; houses have been getting bigger, generally speaking; and we own more devices that require more power. On the site, select Energy 101 for more information.

About Electromagnetic Fields

Whether it comes from natural sources such as the earth or weather conditions, or from Dominion Energy's power facilities and anything connected to them, electricity produces electric and magnetic fields (EMF).

Customers sometimes contact us with concerns about possible health hazards associated with EMFs. Dominion Energy, like other utilities, relies on information from federal, state and international health agencies, which review EMF research and monitor this issue in order to help evaluate potential risks and respond to concerns. Such agencies have not concluded that exposure to EMFs at levels found in our communities poses a health hazard. Therefore, neither the federal government nor the Virginia State Corporation Commission has proposed limits on exposure to EMFs from utility facilities or transmission lines.

The Virginia Department of Health in its final report evaluating EMF research concluded:

"Based on the review and analysis of the exhaustive literature review and other research projects completed under the EMF-RAPID program, the Virginia Department of Health is of the opinion that there is no conclusive and convincing evidence that exposure to extremely low frequency EMF emanated from nearby high voltage transmission lines is causally associated with an increased incidence of cancer or other detrimental health effects in humans. Even if it is assumed that there is an increased risk of cancer as implied in some epidemiologic studies, the empirical relative risk appears to be fairly small in magnitude and the observed association appears to be tenuous. The studies published in the literature lack clear demonstration of a cause and effect relationship as well as a definitive dose-response gradient."

International scientific agencies, including the World Health Organization (WHO) in 2007 and the European Commission's European Health Risk Assessment Network on EMF Exposure in 2010, have sponsored reviews of EMF research and reached similar conclusions. While the conclusions of these reviews are reassuring, Dominion Energy sites and designs its facilities using accepted conservative practices to minimize any impact of EMF levels while balancing environmental, aesthetic and cost factors. This approach is consistent with recommendations of the U.S. National Institute of Environmental Health Sciences and the WHO.

How the Grid Works

The electric grid is the network of power lines that carries electricity from power stations to residential, industrial and commercial customers. To work effectively, electricity must at all times flow safely and reliably throughout the grid so the power is available when needed.

Most people are familiar with the "distribution" power lines and poles that run alongside roadways or are installed underground in neighborhoods. These lines distribute electricity to our homes and businesses.

The "transmission grid" is the part of the network that carries high-voltage electric power from generating stations to distribution facilities.
