Low- and No-Carbon
At the most basic level, diversifying our energy mix reflects simple prudence: The adage about not putting all your eggs in one basket applies here. Supply disruptions can create uncertainty for traditional fuel sources; clouds can render solar generation intermittent. To remain sustainable for the long term, Dominion Energy is making sure it can supply clean energy without interruption, and with minimal exposure to sudden energy price swings, no matter what.
But our commitment to sustainability extends beyond protecting the continuity of our own operations. We are committed to lowering our greenhouse-gas emissions as a matter of principle. We already have achieved much, cutting the amount of carbon dioxide we emit per unit of energy in half. Now we’re focused on cutting even further.
To invest more in renewable solar and wind generation, along with cleaner natural gas, to serve the need for around-the-clock reliable generation of electricity, to extend the life of our carbon-free nuclear facilities, and to use innovation to drive excellence.
How We Performed:
In the past five years we have invested $3.5 billion in renewable generation and grown our solar fleet in Virginia and North Carolina from zero to approximately 1,700 megawatts in service, in construction, or under development. In November 2018, we received approval of an offshore wind pilot project – the second such project in the United States and the first to be owned by an electric utility.

Where We’re Headed:
Dominion Energy is committing to having 3,000 megawatts of new solar and wind under development or in operation by the beginning of 2022. We will bring online our Greensville power station — one of the largest and most environmentally friendly stations of its kind in the world in 2018 — and proceed with our Coastal Virginia Offshore Wind pilot project. We will continue to invest in natural gas and in making the electric grid smarter and harder.
The self-healing and grid hardening activities in the company’s proposed Grid Transformation Plan should reduce outages by 25 percent over the next 10 years.

As part of the 2018 Grid Transformation Plan, the company is seeking Virginia State Corporation Commission concurrence with infrastructure programs including the initial three years of a five-year plan to complete the Smart Meter deployment of 2.1 million smart meters to streamline integration of renewables while ensuring safe and reliable service to customers.
The way we provide energy to our customers is rapidly changing. Evolving economics and better technology are coming together to advance renewable and low-carbon energy, enabling us to reduce a legacy of reliance on fossil fuels. Our strategy for the future depends on using a diverse and balanced mix of resources to deliver reliable and affordable energy to customers. We focus especially on balancing our portfolio to meet our customers’ future energy needs in the most reliable, affordable and environmentally sustainable manner possible.
Backed by an ongoing $1 billion investment, Dominion Energy has grown its solar fleet in Virginia and North Carolina over the past several years from near zero to approximately 1,700 megawatts in service, in construction or under development. That is enough clean energy to power nearly 425,000 homes during peak sunshine.
Nationally, Dominion Energy is ranked 4th in the nation among utility holding companies for ownership of solar facilities, either operational or under development. The company has nearly 2,600 megawatts of solar generating capacity in operation or under development in nine states, including offtake agreements for the company’s utility customers.
Dominion Energy has committed to having another 3,000 megawatts of new solar and wind generation – enough to power 750,000 homes – under development or in operation in Virginia by the beginning of 2022.
The company also is seeking regulatory approval in Virginia for a 100 percent renewable-energy option for residential and small commercial and industrial customers, as well as an option for business customers to purchase renewable generation equal to a specific portion of their energy usage.
As part of our ongoing commitment to bring cleaner energy to customers, we are moving forward on the Mid-Atlantic’s first offshore wind project in a federal lease area. We have signed an agreement and strategic partnership with Ørsted Energy of Denmark, a global leader in offshore wind development, to build two 6-megawatt turbines off the coast of Virginia Beach. This project — the first of its kind owned by an electric utility company — has received approval from Virginia’s State Corporation Commission. It will be located about 27 miles off the coast of Virginia Beach, beyond the coastal viewshed.
Dominion Energy operates a 3,003-megawatt pumped-storage power station in Bath County, Virginia. Pumped storage operates much like a giant battery: When electricity demand is low, the company pumps water from the lower of two reservoirs to the upper one. When demand spikes, valves open to let water run back to the lower reservoir at a rate of 13.5 million gallons per minute. The station powers 750,000 homes and provides a reliable backup source of energy if other sources go offline. We are also exploring the potential for another pumped-storage facility in the coalfields of Southwest Virginia to provide additional energy storage capacity to help balance future renewable resources.
A Lower Carbon Footprint
Dominion Energy has invested in reliable natural gas generation as well. This includes the $1.2 billion Brunswick Power Station that entered service in April 2016. This highly efficient workhorse plant is expected to provide energy savings of more than $1 billion to our customers over its life — and help limit greenhouse gas emissions. From 2007, the portion of our generation supplied by natural gas has grown from 8 percent in 2007 to 32 percent in 2017. Natural gas and nuclear generation will play an important role in our transition to cleaner energy.
Because of this hard work, Dominion Energy has reduced its carbon emission rate by 50 percent over the past 15 years.
Dominion Energy has 11 power stations fueled by natural gas.
