Electric Transmission System
Electric transmission systems carry large amounts of power at high voltages from generators to substations. Transmission systems must be kept highly reliable to prevent blackouts and ensure robust energy markets. Synchrophasor technology has emerged as key enabler for improving transmission reliability and operations. Phasor measurement units (PMUs), phasor data concentrators (PDCs), wide area communications networks, and advanced transmission applications are building blocks of a smarter and more reliable transmission system. This chart shows number of PMUs being deployed as part of the SGIG program and the approximate extent of coverage in the United States resulting from SGIG funding.
The table below includes SGIG program transmission system expenditures.
