Phasor measurement unit deployment (2003-2010)
After the 2003 Northeast blackout, utilities deployed phasor measurement units (PMUs) to get real-time visibility into grid conditions. The sensors measure voltage and current at high speed, giving operators a live picture of grid stability.
Utilities gained real-time situational awareness that helped prevent cascading failures.
PMUs became a standard grid monitoring tool, laying the foundation for modern grid operations.
Like PMUs, DLR is a sensor technology that gives grid operators real-time data to operate lines more efficiently, without building new infrastructure.
