Proposed Pittsylvania Electric Generation Project

We're proposing a project to build two natural gas-fired combustion turbines in Pittsylvania County in Virginia. Also known as "peaking units," these turbines would provide power during periods of peak demand, and also create jobs and economic benefits within the Dan River region.

We're assessing the development of the peaking units in the Berry Hill Industrial Park. The units would have a capacity of approximately 500 megawatts and would power approximately 125,000 homes. The proposed commercial operation date would be April 2022. We selected Berry Hill because of its proximity to the Williams' Transcontinental Pipeline (Transco). This project would be the first business sited within the park. We will assess the environmental, historic and cultural resources. Community outreach will be ongoing throughout the project.

Environmental Commitment

We're committed to a clean energy future that includes more renewables and 55 percent lower carbon emissions by 2030.

We support the statewide clean energy goals outlined in an executive order signed by Virginia Governor Ralph Northam in September 2019. To help Virginia achieve a significantly lower carbon footprint and maintain reliable, cost-effective energy for all customers, we must have a diverse generation mix. Carbon-free nuclear, solar, offshore wind, pumped storage and battery storage are among the proven and emerging technologies included in this mix. The Pittsylvania Electric Generation Project, powered by natural gas, will also be an important part of this diverse generation mix and will play a critical role in enabling the use of more renewables.

Combustion Turbine Technology

Peaking units often only operate during certain times of a day or a few days a season. They can go from idle to producing power within 10 minutes, and offer reliable around-the-clock service.

Peaking units support the growth of newer, sometimes intermittent, sources of energy because they can launch into operation quickly, allowing us to meet customer needs.

The peaking units being proposed at Berry Hill would be similar to those at the Ladysmith Power Station.

Q & A

What is peaking power and why is it needed?

A peaking unit provides power to the grid to supplement the power supply during peak-load periods. Peaking units typically feature combustion turbines, diesel generators, or pumped storage. Peaking units may only be in service certain times during a day and possibly in operation only a few days during a season.

What percentage of the time do peaking units run?

Peaking units are called upon when there is insufficient generation from baseload units during peak-load periods. These periods could be daily loads or seasonal loads. Peaking units typically run 5-20 percent of the time.

If Dominion Energy is launching a battery storage pilot and proposing a pumped hydroelectric facility, then why are the peaking units needed?

Energy storage is critical to ensure a balanced and reliable energy grid as we expand our renewable energy portfolio. Battery storage, which does not produce electricity but stores it for later use, can ramp up to full power within seconds, but can supply that energy for a short duration, as compared to peaking units. Typically for grid applications, energy batteries are sized up to four hours. Peaking units, for example, can provide more energy over a longer period of time. We need a diverse mix of generating resources in order to meet customer needs at the lowest reasonable cost while maintaining reliability and flexibility.

Is the Virginia State Corporation Commission (SCC) approval required for this project?

Yes. Dominion Energy cannot proceed with the project unless the SCC agrees the project is needed and the cost is prudent.
