Summary
Home to nearly 14,000 residents and a designated Green Community in the Commonwealth of MA, the Town of Wayland, partnered with Ameresco on a comprehensive energy efficiency, renewable energy, and resiliency initiative. The first phase of work included energy conservation measures and solar PV installations at four sites. In the second phase, an advanced resiliency initiative was implemented to ensure the Town’s emergency shelter can access power in the event of emergencies that cause outages.
“We are thrilled with this innovative solution that will help Wayland weather future storms and provide our emergency shelter with power fueled by clean solar energy. Its location at the Middle School also will help students learn about the importance of resiliency as we look to the future.”

Customer Benefits
As part of its designation as a Green Community, Wayland is committed to reducing their energy consumption by 20%. Partnering with Ameresco on this comprehensive energy savings and capital upgrade program, empowered the Town to achieve their objectives, implement critical infrastructure projects, and secure energy cost savings. Additionally, the advanced resiliency project ensures that Wayland’s emergency shelter can access backup power in the event of emergencies that cause outages. Other project benefits include:
- Energy cost savings of ~$8M over project term
- Offset future capital expenditures
- Reduced heating and cooling loads
- Solar arrays generate electricity to offset 25% of municipal electric needs
- Solar renewable net metering credits
- Ensured continuity of power in the event of utility outage at emergency shelter
- Reduction of greenhouse gas emissions equivalent to the annual electricity usage in 113 homes
Solution
Phase one of the project included the design and implementation of efficiency measures at eight school and town buildings with guaranteed energy savings during the 20-year contract term. Through a PPA, Ameresco also constructed four solar PV installations at the Wayland High School, Wayland Middle School, Town Building, and DPW Facility. Phase two of the project paired the existing solar canopy facility at the Middle School, which also serves as the Town’s emergency shelter, with the emergency generator to support the shelter during utility outages.
