Solar batteries are now part of an energy program that helps National Grid customers in Rhode Island, Massachusetts and New York reduce their electricity use during hot, summer days.
As part the program ConnectedSolutions, National Grid has started sending electronic signals to batteries in people’s homes to feed more of its stored energy into the electrical grid when energy use peaks between 2 p.m. and 5 p.m.
Paul Wassink, senior engineer at National Grid, said extra energy from the batteries means less power is coming from traditional energy resources, which he said is beneficial in the long-term.
"There will be less pollution in the air, there will be a smaller electrical system, there will be fewer power plants, and electricity rates will go lower over time," he said.
The program was originally designed for cutomers with central air conditioning and qualified wifi thermostats, which work by signaling the thermostats to cool homes before peak energy times start.
In addition to solar batteries, more wifi thermostats have also been added to the program.
Currently, more than 8,000 customers in Rhode Island, Massachusetts and New York have registered their thermostats for ConnectedSolutions.
In National Grid's service area, peak days happen about 12 to 15 times a year.
