Green Energy Life Cycle Assessment Tool (GELCAT) and User Manual

The Green Energy Life Cycle Assessment Tool (GELCAT) is a Microsoft Excel®-based screening tool that can be used to determine the economic viability and energy and environmental benefits/costs of selected renewable energy technologies at wastewater treatment facilities. In its current version, three renewable electric technologies are represented: photovoltaic systems, wind turbine generators, and hydro-turbine generators. Published in 2012.  

As of August 2023, the GELCAT tool has been discontinued. An Executive Summary is available below, but any reference to the GELCAT tool is for historical information.
