The 2.7-megawatt (MW) system, which was designed and is currently being built by Borrego Solar and financed by a joint venture between Greenwood Energy and Soltage called Soltage Greenwood, will be installed on the landfill site’s buffer zone, alongside an existing 8 MW gas-to-energy generating facility that utilizes the methane captured from both the active and capped sections of the landfill.
The entire site is owned by Casella Waste Systems, and the ground-mounted solar array consisting of 9,018 panels is expected to generate approximately 3,199 megawatt-hours annually, enough to power 261 homes for an entire year. The power generated will be sold to Vermont Electric Power Producers under the state’s Sustainably Priced Energy Development (SPEED) Standard Offer Program—one of the nation’s first feed-in-tariff programs. Solar energy capacity has tripled in Vermont in the last three years, and the state currently ranks first in solar jobs per capita, nationwide.
The project required zero upfront costs from Casella Waste Systems thanks to a power purchase agreement (PPA) with Soltage Greenwood.
