US utility National Grid is expanding its application of volt optimisation to increase consumer energy and grid efficiency.
The energy provider to 20 million customers, in partnership with Utilidata, is installing a real-time VOLT optimisation technology for consumers in Massachusetts.
This follows installation for Rhode Island and New York customers in 2013, 2016 and 2017. Installation has resulted in 3% energy savings for National Grid customers.
Chris Kelly, senior vice president of electric process and engineering at National Grid, said: “Our work together has led to significant savings year after year, so it only made sense to expand this solution to benefit our customers in Massachusetts. “
The technology enables utility companies to access real-time grid status information to fine-tune distribution delivery voltages.
This allows consumers to reduce their energy use without disrupting the services they are offering.
The technology is expected to help National Grid to simplify and improve integrating its grid with distributed and renewable energy resources such as wind and solar power and electric vehicles.
The project is part of efforts by the utility to reduce its greenhouse gas emissions by 80% by 2050.
