About Our Solar Arrays
As a major step toward accomplishing its sustainability goals and principles, the City of Lebanon began installation of solar arrays at City-owned sites in 2019 and will continue into the foreseeable future in discrete phases.
In 2019, Lebanon partnered with ReVision Energy to install solar at seven sites: the Kilton Public Library, Landfill Recycling Center, Landfill Maintenance Garage Building, Public Works Administration Building, Public Works Garage, the Police Station, and the Wastewater Treatment Plant. Phase 1 was completed on December 24, 2019. All but one, the Landfill Maintenance Garage Solar (see below), of these arrays is now active and generating clean electricity for the City. These seven arrays have a total size of 777 kilowatts DC (615 kilowatts AC) and will produce roughly 23% of the City’s electric load on an annual basis.
Landfill Maintenance Garage Solar
The Landfill Maintenance Garage array was taken down in 2020 because the array’s inverters, the device that converts electricity from direct current (DC) to alternating current (AC), were interfering with City communication systems. That problem was resolved by ReVision Energy in the Summer of 2021, but another issue cropped up with the approval of the Landfill Gas-To-Energy Project. Unfortunately, if the solar production were to be added to the landfill gas project’s electricity, it would push the total production from that site beyond a threshold that would trigger the need for a hefty equipment upgrade to the electric distribution circuit in West Lebanon. The City is looking for less expensive alternatives that would allow the reinstallation of solar at this location or another location.
In 2020, the City Manager approved funding for two additional arrays to be built on the newly renovated Civic Memorial Field Maintenance Garage on Aldrich Avenue and the Valley Cemetery Building on Mascoma Street. Both buildings were renovated with almost optimal roof angles for solar. The buildings were finished in late 2021 and Catamount Solar of Randolph, Vermont won the bid for solar installation. The array sizes are 27 kW DC for the Valley Cemetery Building and 24.5 kW DC for the Civic Memorial Field Maintenance Garage. The city is working on Wi-Fi accessibility to these buildings to allow remote monitoring of their solar production.
In July 2022, City Management approved a plan to develop another large phase of solar on multiple sites throughout the city. The NH Senate Bill 321 that was passed in 2022 allows Lebanon to produce more electricity than the municipality itself needs through its solar and landfill gas projects. The excess could then be made available to other Lebanon businesses or institutions. This process may be managed through Lebanon Community Power if the two projects come to fruition in a coordinated manner.
