District heating and cooling systems for communities through power plant retrofit and distribution networks. Phase 1: identificatzon and assessment. Final report, Volume II. Detailed results

The Phase I Identification and Assessment Study was aimed at surveying the State of Wisconsin to identify potential sites for a district heating system and evaluating these sites in terms of their technical, institutional and economic merits. Specific objectives of the study were to: identify candidate plants and service areas and to perform an energy market analysis for selected areas; identify and evaluate plant retrofit and distribution alternatives for the selected service areas; identify and evaluate institutional problems within the infrastructure; and perform an economic analysis for the candidate sites. The overall approach consisted of surveying the State of Wisconsin to identify all existing intermediate and base-loaded electric generating facilities. Once identified, screening criteria were developed to narrow the list to the three most promising sites. For each of the three sites, an extensive market analysis was performed to identify and characterize thermal loads and survey potential users on their views and concerns on the concept. Parallel to this effort, each of the three sites was evaluated on its technical and institutional merits. The technical evaluation centered on identifying and evaluating utility plant retrofit schemes and distribution system alternatives to service the identified thermal market. The institutional analysis evaluated potential barriers such as environmental, distribution system right-of-way and legal issues within the infrastructure of the state, city and community. Finally, all previous aspects of the analysis were combined to determine the economic viability of each site. The most promising site is Green Bay where process heat loads as well as building heat loads are located near the Pulliam Power Plant
