Net Zero

Our Net Zero opens in a new window commitment includes carbon and methane emissions within our direct control (known as Scope 1 emissions), as well as Scope 2 and material categories of Scope 3 emissions, including: electricity purchased to power the grid, fossil fuel purchased for our power stations and gas distribution systems, and consumption of gas sold to our end-use customers.

Reliability and affordability remain fundamental to our clean-energy strategy, because the energy transition will not succeed unless customers can count on safe, reliable, affordable service. We also recognize that the most vulnerable suffer the greatest when reliability and affordability are not maintained. We’re dedicated to a sustainable, ethical, and just clean-energy transition.

Most of the company’s Scope 1 emissions come from burning fossil fuels in our electric generation fleet. As we carry out our commitment to deliver increasingly clean energy, our changing generation mix has reduced emissions on the electric side. Methane emissions from our natural gas businesses account for a small percentage of the company’s overall Scope 1 emissions.

Scope 2 emissions consist of transmission and distribution line losses associated with wholesale purchased power, in addition to electricity consumed by company facilities located outside of Dominion Energy’s electric service territories. Scope 2 emissions constitute only a small sliver of our total emissions. Nevertheless, we continue to find ways to reduce electric consumption at our facilities, both within and outside of our electric service territory. In 2023, we installed and integrated utility meters in our building management systems at 16 facilities across three states. These meters allow us to monitor in real time the consumption of gas, electricity, and water in order to track and drive reductions in our consumption.

Scope 3 emissions include those from three material categories: electricity purchased to power the grid, fossil fuel purchased for our power stations and gas distribution systems, and consumption of sales gas by our natural gas customers. Scope 3 emissions were almost evenly split between our electric and natural gas businesses in 2023. We are evaluating and implementing solutions to reduce Scope 3 emissions, including customer efficiency measures. When feasible, we are also using certified natural gas — gas that has been certified by a third party to reduce emissions and environmental impact during production and transport — in our gas-fired power stations.

Scope 1 Carbon Emissions from Power Generation

CO₂ emissions MMT (million metric tons)

Scope 1 Carbon Emissions from Power Generation: 2023 showed a 53% reduction in C02 with 27.0 MMT of C02 compared to a 2005 baseline of 57.4 MMT of c02.

Scope 1 Methane Emissions from Natural Gas Operations

CH₄ emissions MT (thousand metric tons)

Scope 1 Methane Emissions from Natural Gas: 2023 showed a 50% reduction in methane with 42.6 MT methane compared to a 2010 baseline of 85.3 MT of methane.

We began building our renewable portfolio in 2013. Since then, we have grown it to roughly 12,000 MW in service or development as of early 2024. We are also adding energy storage to help integrate renewables and provide grid reliability, enabling us to store energy to serve our customers with renewable energy even when the sun isn’t shining.

With its expected completion in 2026, our Coastal Virginia Offshore Wind commercial project’s 176 turbines will have a capacity of up to 2,600 MW of power — enough to power 660,000 homes and businesses — and will avoid up to 5 million metric tons of carbon emissions per year. In July and August 2024, we announced our intention to acquire two additional offshore wind lease areas, totaling approximately 215,000 acres for potential future offshore wind development.

In 2013, we brought our first solar generation project online. Since then, we have grown our solar portfolio to roughly 9,000 MW in service or under development as of early 2024 — enough to power 2.25 million homes at peak output. We have one of the largest solar portfolios among investor-owned utilities in the United States. In 2023, we added 200 MW of solar to our system.

Dominion Energy has jointly owned and operated the world’s second-largest energy storage facility, the 3,003-MW pumped-storage hydroelectric facility in Bath County, Virginia, since 1985, as well as a similar 576-MW facility in Jenkinsville, South Carolina, since 1978.

In 2023, we brought online our Dry Bridge Battery Energy Storage System opens in a new window in Chesterfield, Virginia — a 20-MW system that can store enough electricity to power 5,000 homes for up to four hours. Dominion Energy South Carolina signed power purchase agreements for three hybrid solar projects with battery energy storage.

In September 2023, we proposed to the Virginia State Corporation Commission (SCC) a groundbreaking pilot project that would test two alternatives to lithium-ion batteries: a zinc-hybrid battery developed by Eos Energy Enterprises, and an iron-air battery developed by Form Energy. The iron-air technology has the potential to discharge to the grid for up to 100 hours — 25 times longer than conventional lithium-ion batteries. The SCC approved these projects in May 2024.

We also announced, in November 2023, that we are partnering with Virginia State University (VSU) to develop an innovative 1.5-MW battery storage project to provide backup power to the VSU Multi-Purpose Center. EnerVenue's Energy Storage Vessels use metal-hydrogen technology, a variation of what's used in the aerospace industry, that can discharge energy for up to 10 hours.

As of December 31, 2023, through our strategic alliance with Vanguard Renewables, 21 dairy renewable natural gas facilities were under development or construction in Colorado, Nevada, Idaho, Georgia, Kansas, Texas, and New Mexico. They are expected to be completed in 2024 and 2025. Additionally, Align RNG — an equal partnership with Smithfield Foods — had four projects with multiple phases in North Carolina, Arizona, and Virginia with one project phase in service and three under construction at the end of 2023. They are expected to be placed in service in 2024 through 2027.
