The utility company says thousands of people across the Bay State have lost power during this blistering heat wave, and many outages have been caused by equipment simply overheating.
Eversource spokesman Chris McKinnon explained the problem, saying "there's all different types of equipment in our system. We have systems that are above ground; we also have equipment underground," and some of that equipment is "exposed to the elements of mother nature."
McKinnon says the risk of overheating from high temperatures is made worse by heavy demand on the electrical system. The utility is asking customers to help reduce the load on the network during the peak usage hours between 2 p.m. and 7 p.m..
"It is helpful if folks avoid using big appliances like the washer or drier, turning on your electric stove, things like that," says McKinnon.
Between Tuesday and Thursday afternoon, McKinnon says Eversource restored power to approximately 40,000 customers statewide.
As of 11:15 a.m. Friday, close to 1,500 outages were reported on MEMA's outage map, including 99% of the town of Warwick, MA.
