Protecting the Environment

Sustainable Operations

Our concern for sustainability extends beyond our direct gas and electric infrastructure.

We also demonstrate it in our office buildings and supply chain network. Every day, our employees are taking steps to help us achieve our commitments and reduce our impact on the environment.

Supply Chain Sustainability

Our supply chain plays an integral role in our commitment to sustainability. Our efforts are focused on increasing partnership and engagement with suppliers, industry peers, and employees to improve environmental and social sustainability performance, implement best practices, minimize negative environmental impacts, ensure respect for human rights, and mitigate potential sustainability risk across our value-chain.

Dominion Energy is a member of the Electric Utility Industry Sustainable Supply Chain Alliance (EUISSCA) and is committed to engaging our peers and suppliers on sustainability to ensure continuous improvement. Our vice president of Shared Services chairs EUISSCA’s executive committee.

In 2020, the company established a qualifications policy that requires environmental and sustainability evaluations during the procurement process to help select suppliers who are committed to ensuring environmental compliance are awarded contracts by Dominion Energy. In addition, we annually assess key suppliers on their supply chain.

We have started a program to improve the sustainability of our natural gas supply chain. For details, see the section in this report on “Reducing Methane Emissions.” We also consider supply-chain diversity an important component of supply-chain sustainability. For more information, see the section on “Supplier Diversity”.

Reducing Waste

Dominion Energy agrees with the saying that waste is a resource in the wrong place. From coal ash to compost, Dominion Energy has consistently sought new ways to recycle our waste where feasible and reduce the amount of material we send to landfills. To minimize it, the company maintains an array of waste-reduction programs including recycling, composting, and a zero-waste approach to numerous company events.

Coal Ash

As we go forward with planned coal facility closures, the company maintains an extensive program to recycle coal ash, close coal ash ponds, and ensure the safe and environmentally responsible disposition of coal ash. For example, over the next decade and a half, we plan to remove approximately 15 million cubic yards of coal ash currently stored in two coal ash ponds at Chesterfield Power Station in Virginia. The coal ash will either be recycled or moved to a lined landfill that meets federal and state coal-ash regulations. In 2020, we awarded a contract for the beneficiation and use of up to 8.1 million tons of reclaimed coal ash, which will replace virgin raw materials in the production of Portland cement.

In South Carolina, we have recycled more than 200,000 tons of coal ash from our Canadys, Wateree, and Williams Power Stations.

Waste Reduction Highlights

Workplace Sustainability

Sustainability applies as much to those working in our offices as it does to those working on projects in the field. We want employees to cultivate a sustainability outlook throughout the day, whether they are planning a 200-mile transmission line or grabbing lunch in the cafeteria.

To foster that mindset in our offices, our Workplace Sustainability Team — a grassroots collaboration among employees — serves as an advocate for sustainability-focused innovations. The team meets quarterly to vet ideas, track progress, and plan initiatives.

Composting Food Waste

In 2020, we started five new composting programs, including our “Scraps From Home” program that collects 800-1,000 pounds per month of organic waste from employees working remotely, and a pilot program to compost wood chips from right-of-way clearings in Ohio. Our composting program achieved a company record in 2020, diverting over 94,000 pounds of organic material from landfills to be recycled into sustainable soil. In Akron, Ohio, we have partnered with Rubber City Reuse to turn our food scraps into compost for community gardens. In Virginia, employees at our Ladysmith Power Station, located between Richmond and Fredericksburg, explored how to start a composting program, even though the station lies outside the service territory of haul-away composting partners. They concluded that using a contained system with worms, or “vermicomposting,” could sustainably recycle organic waste while minimizing costs and maintaining site safety and environmental compliance. The vermicompost system they installed requires no manual operation.

Building and Construction Management

We strive for Leadership in Energy & Environmental Design (LEED) Silver-level certification in new office construction, not only to encourage environmental stewardship, but also to provide an optimized work environment for employees. LEED building practices support healthier, more productive workplaces, reduce stress on the environment by encouraging energy and resource-efficient buildings, and produce savings from increased building value and decreased utility costs.

We employ LEED best practices when renovating buildings, and many of our office buildings use automation systems to optimize the efficiency of HVAC and other facility systems. We track and manage office refrigeration, avoid the use of chlorofluorocarbons, and are replacing our R-22 refrigerant systems with systems that use ozone-safe R-410A.


One James River Plaza Demolition

In 2020, Dominion Energy demolished a 21-story office building in downtown Richmond, Virginia. Ultimately, 98.8% of the building’s material was recycled, including 4,995 gross tons of metal and 76,568 tons of concrete.

Will Booker, regional manager for the wrecking company brought in to do the job, told Construction & Demolition Recycling magazine: “We went to great lengths to make sure we met and exceeded Dominion Energy and [general contractor] Hourigan|Clayco’s goal on this project. In fact, a great deal of the crushed concrete was brought back on-site for building ramps and for other uses on the project, which is certainly rare. You don’t often have the same materials crushed and returned to the site for reuse.”
