State of Wisconsin
Comprehensive Heating Plant Feasibility Study
The State of Wisconsin currently uses coal to power several local heating plants. The state was interested in studying the viability of reducing or eliminating the use of coal by replacing it with more sustainable and cleaner fuels, such as biomass. The State desired to find solutions that were cost effective, reduced emissions, and increase plant efficiency and reliability. Syska was contracted as the prime consultant to investigate 13 heating plant options on a life cycle basis for the State.
Syska's Energy Services team studied the University of Wisconsin's Madison Campus Charter Street (CSHP) and Walnut Street Heating Plant (WSHP), and Capital Health and Power Plant (CHPP), as well as an integrated plant that connected the CHPP with the CSHP to provide district energy to the Isthmus area. The team also conducted a companion alternative fuels study that documented available alternative fuels, including proximity, cost, and transportation method.
Biogasificiation was explored by using Johnson Controls Nexterra biomass gasified boiler. The viability of cogeneratiion in several formats was also studied, including connecting all plants into one combined energy plant to consolidate energy requirements. Final recommendations from this study were a critical component in Governor Doyle's statement that the State of Wisconsin should move away from coal in state owned heating facilities.
