I do not answer calls from callers I do not recognize, so I let this go to the answering machine.
They did not leave a message so I am blocking this number.
I am on the do not call list but that only works for legitimate businesses, so this is most likely a SCAM.
Shows as a VOIP number. Feel certain Eversource would 1) never use a VOIP number, and 2) would identify itself on the ID (however, beware that scammers can put whatever they like on the ID section. )
