Tessman Road Landfill Solar Energy Cover
When asked to redesign an existing closure system for a portion of a landfill located in an arid, windy area with bad soil that makes it difficult to grow grass, HDR created a design to transform a landfill closure system into a renewable energy park. The result provides environmental protection and generates revenue. The design places flexible solar panels directly on the surface of an exposed geomembrane cap with the solar power tied into the existing landfill gas-to-energy system. The solar energy cover gives the landfill owner, Republic Services, the ability to generate electricity that can be sold to the local power company or used for onsite energy needs.
More than just a win-win situation, the Tessman Road Landfill Solar Energy Cover is a win-win-win. It provides a triple play of benefits: generating renewable energy, creating a revenue stream and reducing maintenance requirements by eliminating the need to mow and maintain a grass-covered landfill cap (also reducing carbon dioxide emissions). The economic benefits of the solar cap can be expanded by increasing the density of solar panels on the existing project area or increasing the area of the cap as other areas reach final closure grades.
