The technology, known as ‘synchrophasors’, is expected to provide real-time information about conditions on the transmission grid. The research project, funded by a $1.5m grant from the US Department of Energy, also involves Quanta Technology of Raleigh, North Carolina.

Paul Koonce, CEO of Dominion Virginia Power, said: “A smarter, more efficient and reliable electric grid means better service for customers, benefits for the environment and lower costs in the long run. What is particularly appealing about this technology is that it can be applied to our existing transmission network, not just new projects.”

The new technology also provides grid operators with the ability to foresee, prevent and manage potential overloads on the grid.

Dominion is a producer and transporter of energy, with a portfolio of approximately 27,500MW of generation and approximately 6,000 miles of electric transmission lines.
