World : Grid Stability from Siemens…NY DER Consumer Protections…Engie in Africa

Siemens mobile solution adds grid stability for Dominion

Siemens is providing Dominion Energy with a new mobile tool to create grid stability during disturbances and faults. Called the Mobile SVC STATCOM, the technology provides fast and controlled reactive power.

The Virginia-based utility will be able to move the device anywhere grid support is needed, which is an advantage during surprise outages.

The mobile technology allows utilities to avoid installation of permanent substations that can take years to plan and build. In contrast, STATCOM technology can be moved within days.

“By using this device, Dominion Energy is meeting today’s need to maintain reliability but also prepare their transmission system for future challenges,” said Nicolas Sanloup, head of Siemens Transmission Solutions. “Siemens is proud to bring this industry-leading solution to Dominion Energy to help them navigate an ever changing energy landscape and provide greater reliability to their consumers.”

The substation technology will also help Dominion Energy manage the growing number of renewable and distributed energy resources on its power grid. As these generation sources come online, they often change how a traditional grid operates. Temporary STATCOM installation helps enhance grid stability, giving the utility sufficient time to plan for renewables on its system. The substation technology also responds to any faults on the transmission network within milliseconds.

Siemens expects to deliver the first mobile device in mid-2018.
