The City of Pendleton, Oregon, has taken a significant leap towards energy sustainability with the installation of a pioneering solar canopy at its Wastewater Treatment and Resource Recovery Facility (WWTRRF). This innovative project not only represents a milestone in the city's energy initiatives but also promises to enhance the performance of the facility. By generating approximately 325,000 kilowatt-hours (kWh) of electricity annually, the canopy is set to reduce energy costs significantly while contributing to environmental conservation efforts. This endeavor, led by Ameresco, marks a notable advancement in the region's commitment to sustainable infrastructure. Solar Canopy Helps Reduce Energy Costs
The solar canopy project in Pendleton is a testament to the city's dedication to developing efficient energy solutions. As highlighted by Kyle Willman, Superintendent of the Wastewater Treatment Resource Recovery Facility, the installation of the solar canopy is a major step forward. It not only aids in reducing energy costs but also minimizes the environmental footprint of the facility. By providing on-site energy production, the canopy helps in cutting down the operational expenses substantially.
Moreover, the canopy offers additional benefits beyond just energy savings. By shading the chlorine contact chamber, it plays a crucial role in improving water quality and reducing effluent temperatures. These improvements contribute to a healthier aquatic ecosystem, benefiting the entire community. The partnership with Ameresco and the support from state and local authorities have been instrumental in realizing this forward-thinking investment, demonstrating the power of collaborative efforts in achieving sustainability goals.

This solar canopy is part of a broader infrastructure improvement initiative undertaken by the City of Pendleton. Delivered through an Energy Savings Performance Contract (ESPC) with Ameresco, the project guarantees both price and performance, ensuring the participation of disadvantaged and local businesses. Lou Maltezos, President of Central & Western USA and Canada Regions at Ameresco, expressed pride in collaborating with the city to build a resilient future.
Such innovative energy solutions not only bring significant economic benefits but also support essential city infrastructure. By offsetting about 30% of the WWTRRF's total energy consumption, the project exemplifies how strategic energy initiatives can enhance operational efficiency. Additionally, the project's funding through state grants, utility incentives, and city resources underscores the importance of leveraging various financial avenues to drive sustainable development. Future plans for a battery energy storage system (BESS) promise to further decrease operational costs, highlighting the city's commitment to long-term energy resilience.
