Renewable Energy


Worcester has developed three goals related to clean and affordable energy. 

  • By 2030: Use 100% renewable energy for municipal facilities
  • By 2035: Provide 100% residential renewable electricity city-wide through the Community Choice Aggregation program
  • By 2045: Use 100% renewable energy for residences and businesses, including for heating and transportation

Municipal Solar Generation

Over the last decade, the City has aggressively installed solar on its facilities, including 12 schools, 2 water filtration plants, the senior center, and the closed landfill on Greenwood Street. Last year alone, municipal solar systems produced more than 11 million kWhs of clean energy. This is equivalent to about 10% of our electricity use in municipal buildings.

Solar Arrays by Location Type in Worcester

Solar array

Worcester’s municipally owned and operated solar farm was built in 2017 and is as big as 19 football fields.

And it generates up to 10,000 MWh/year, powering the equivalent of 1,300 homes! 

In 2017, the City of Worcester turned on more than 28,000 solar panels atop the former Greenwood Street Landfill. The largest municipally-owned solar generating facility in New England, the solar farm can generate up to 10,000 mWh/year, or enough energy to power 1,340 homes for a year.

Community Enrollment Reduces Harmful Emissions

The more people who enroll in the ElectriCITY program, the more greenhouse gas emissions Worcester avoids. So far, 2023 has seen the highest program participation, and thus the highest monthly emissions levels avoided since 2020. Overall, the program has prevented 110 million lbs of carbon from going into the atmosphere!
