July 2026 Northern Virginia Data Center Event - Effects on Voltage & Grid Frequency

This animation visualizes how the Northern Virginia data center event on July 22nd affected voltage and frequency across the Eastern Interconnection. Powered by the Ting electrical safety network, this map shows how a sudden 3 GW load loss propagated across the grid in seconds, revealing both voltage disturbances and frequency response. At the start of the event, three sharp voltage sags appear. These may be associated with the initiating transmission fault event and possible utility re-close attempts. Additional re-close activity may also be visible later in the animation. In localized areas of Northern Virginia, the voltage drops were severe enough to cause momentary power interruptions. #GridReliability #DataCenters #Utilities #PowerGrid
