 In 1967 the substation on Cedar Street (Station 453) was built, and in 1968 a new substation (Station 41) was completed and began distributing power to Wellesley Hills, effectively halting the original substation's use.Today, the WMLP has a total of 33 distribution lines throughout Wellesley and owns nine supply lines, six from the NSTAR substation in Newton, Massachusetts and three from the NSTAR substation in Needham, Massachusetts.The voltage supplied from the aforementioned substations in Newton and Needham enter Wellesley at 13,800 kV and are either distributed through the town at 13.8 kV or, through the substations and stepdown transformers, distributed at 4 kV.
