Book Description
The Department of Energy, Minnesota Energy Agency, Northern States Power Company, and other local government and private organizations are cooperatively performing an in-depth application study to determine the feasibility of district heating for a large northern-U.S. city. Over 90% of the space- and water-heating requirements are currently supplied by oil and gas. Hence, district heating can potentially replace large quantities of scarce fuels with coal or nuclear resources. In addition, district heating, using a co-generation power plant, substantially increases the fuel-utilization efficiency when compared to an electric-only plant. A Swedish firm, AB Atomenergi, is performing a preliminary economic and technical assessment. The analysis uses current Swedish district-heating technology and experience, and adapts it, where necessary, to U.S. conditions. Preliminary Swedish results indicate favorable economics for a large system, which includes residential areas, when technology innovations such as temperature-resistant plastic piping are used. For conventional-piping technology the economics appear favorable for the commercial areas of the city core. The peak heat load for the Twin Cities is approximately 4200 MW(t). The scenario presented by AB Atomenergi assumes 2250 MW(t) would be supplied by co-generation units, and the remaining 2000 MW(t) would be peaking, heat-only units. The dual-purpose units would be used as the base load and would supply 90% of the total annual energy load. The interest generated by the joint U.S.-Swedish effort has guided the participants to more-detailed investigations of (1) energy sources, (2) distribution and building systems, (3) environmental acceptability, and (4) financial and organizational alternatives.

Book Description
The Department of Energy, Minnesota Energy Agency, Northern States Power Company, and other local government and private organizations are cooperatively performing an in-depth application study to determine the feasibility of district heating for a large northern US city. A Swedish firm, Studsvik, has developed an overall scenario and has attempted to show the potential of a fully implemented system. The proposed system would be about 2600 MW(t) and cover a significant portion of both Minneapolis and St. Paul. This study has proceeded in parallel with more in-depth studies of particular issues, such as detailed piping network plans in central St. Paul and cogeneration plant conversion cost study - both sponsored by Northern States Power Company. The overall conclusions that can be drawn at the present time are: (1) the concept is technically feasible; (2) it has great value from the fuel conservation aspect; and (3) the economics are viable with an appropriate financing system.
