Title: District heating and cooling for the city and port of Tacoma: Phase 1, Feasibility study

Technical Report ·
OSTI ID:5525723

Expansion and up grade of Tacoma's largest sewage treatment facility together with a proposed biomass cogeneration plant sparked the interest of Washington State Energy Office (WSEO) to look at the district heating and cooling (DHC) potential. Sewage effluent is used in several Swedish cities as a heat source in heat pump assisted district heating systems. The treament facility is located adjacent to downtown and the new effluent transfer pipline will run through the port district in route to the Commencement Bay. Other potential heat sources are the proposed biomass cogeneration plant and Simpson Tacoma Kraft Pulp and Paper Mill. The pulp mill is also adjacent to downtown, however, the proposed cogeneration plant will be about a mile away. A preliminary district heating analysis was performed using a computer analysis tool called HEATPLAN. The analysis was favorable and a decision to move ahead with further study was made by WSEO.
