Project Power Up – Helping to keep the lights on in Ukraine in the face of electronic warfare
Summary: Cisco Talos worked with Ukrenergo, Ukraine's high-voltage transmission operator, on Project PowerUp to counter deliberate GPS jamming that prevents substations from accurately timestamping grid data. After nearly half of Ukraine's energy infrastructure was destroyed in the first winter of the invasion, Talos and Cisco's IoT division designed custom devices based on Industrial Ethernet switches to provide timing holdover without atomic clocks.
What you should know: Ukraine's grid operators lost reliable GPS timing because of electronic warfare, and without synchronized timestamps they cannot diagnose faults or balance loads during peak demand - the same dependency on GPS timing sits inside high-voltage substations well beyond Ukraine's borders.
