Protecting the Environment

Clean Water

By adopting new technology and applying creative approaches, we are using less water and finding new ways to reuse it.

As we generate and deliver energy to our customers, we strive to minimize our impacts through the use of measures that protect waterways.

Reducing Use

In our path toward achieving water security, we are committed to reducing water consumption by employing low-water technologies (e.g., air-cooled rather than water-cooled condensers at our power generation operations). In 2019, Dominion Energy Virginia’s Power Generation division developed an environmental stewardship program to encourage employee involvement. One of the program’s projects involved our Bear Garden Power Station in Buckingham County, Virginia: Changing the operation of its cooling tower prevented taking water from the James River, conserving 50 million gallons per year. In our Western-state operations in Utah, Wyoming, and Idaho, our goal for Wexpro is to reduce water use by 21 million gallons over five years. In 2020, the first year of that period, Wexpro reduced fresh water use by 4.5 million gallons.

Water Protection

Not only are we using less water, we also are taking steps to protect water bodies. For example, to reduce the risk of releasing oil into the environment, Dominion Energy Virginia is replacing oil-filled breakers and power transformers and installing oil-containment systems around new and existing transformers. The company’s electric distribution business unit also continues to eliminate oil-filled pad-mount switches, at the rate of 10 to 15 per year.

At our Bath County and Brunswick County Power Stations, we have developed innovative alternatives to the use of chemicals for treating algae in stormwater runoff ponds. Employees at Bath used Koi from a local hatchery that will naturally consume the algae. Employees at Brunswick installed a solar-powered aeration system that will control algae.

Our water-protection efforts extend beyond policing our own activity. For instance, 2020 marked the sixth year we teamed up with the Western Reserve Land Conservancy in Ohio on a Watershed Mini Grant Program, which distributes funds to groups that strive to protect water quality.
