Dominion Energy was recently recognized by the Southeastern Electric Exchange (SEE) for an innovative project that addressed voltage control and reliability on its transmission system.
With the closure of the Chesapeake Energy Center and the influx of new renewable generation, the Dominion Energy team was faced with maintaining voltage quality and stability. Many solutions were considered, but the team settled on a proven technology that was installed in a creative, networked configuration.
“Maintaining a strong, reliable grid is the driving force behind what we do every day,” said Scott Miller, vice president-electric transmission, Dominion Energy. “We knew it was critical to find a cost-effective solution that provides fast-response dynamic voltage support.”
The team installed a network of static synchronous compensators (STATCOMs) at four substations in the Hampton Roads area. One of the STATCOMs is a spare, so any one of the devices can be taken out of service while the others continue to mitigate voltage issues. This unconventional approach is providing better voltage control and redundancy, supporting the integration of solar energy in Virginia.
This project marked a significant milestone for Dominion Energy and the energy industry—it is the first time that so many STATCOMs have been deployed in one area.
“I am so proud of the ingenuity of my colleagues. In the end, our customers will benefit and critical infrastructure in Hampton Roads will experience better reliability,” Miller said.
The Chairman’s Award is given to SEE member companies to recognize best-in-class projects in the substation category. The winners were chosen by a panel of judges following an international nomination process, and the awards were presented at SEE’s Annual Conference and Trade Show in Orlando.
