Technology suppliers, waste system managers and project developers across North America are endeavoring to find and implement new approaches to converting the energy in waste to electricity or alternate fuels. These entities, as well as potential financiers and communities that might benefit from these emerging technologies, often retain an independent engineer to assist in establishing the status and risks of the technology itself or the feasibility a specific project that has been proposed. Although independent engineering assessments are a well-established element of the non-recourse finance process, individuals and organizations new to the development process are often unfamiliar with the usefulness and content of these assessments. In the context of emerging technology-based projects, this paper will provide an overview of the role of an independent engineer in the development process, explain the typical assessment process, and discuss the content of a typical independent engineering report (“IE Report”).
