Olympia, Washington is exploring a scheme that could become the country's most innovative district heating and cooling (HDC) systems, whose unique features are: (1) electric-driven heat pumps rated at 10 MW produce baseload hot and chilled water, (2) sewage effluent as the source fluid for the water-to-water heat pumps, and (3) a group of state and local agencies and business groups as sponsors of the project. The city has made an inventory of 160 downtown buildings and the Capital government buildings, as well as new construction and energy conservation measures, to determine heating and cooling demands. The project has prepared a conceptual plan, evaluated four potential hydrothermal sources for heat pumps, and is now focusing on customer retrofitting costs and probable paybacks.
