LED Streetlight Retrofit 

The Wellesley Municipal Light Plant (WMLP) has completed the retrofit of between 2,850 and 3,100 streetlights with Light Emitting Diode (LED) fixtures.  The streetlight retrofit will eliminate 1,025,959 kilowatt-hours of electricity every year, a reduction that is the equivalent of taking 152 regular-sized passenger vehicles off the road.  In addition to the environmental benefits, Wellesley taxpayers will save as much as $133,400 annually beginning in Fiscal Year 2019.

This project was partially funded by a contribution from the Wellesley Board of Selectmen and a grant from the Massachusetts Department of Energy Resources (DOER). The Municipal Light Board approved the funding for the remaining amount from the WMLP's available cash. 

The specific cost breakdown is:                                     

Total LED cost$860,750
Board of Selectmen contribution$105,000
DOER grant$193,050
WMLP funding$562,700

These LED streetlights are expected to last an average of 20 years and save Wellesley taxpayers an estimated $2.6 million during that time period.
