Jcn..-Jze RllSS [.,.G1 I A 150 ton per day MSW plant is best suited to provide non- interruptable steam to all the space heating and some process needs; while supplying the remaining process needs on an inter- rupt~ble basis. This plant size minimizes overcapacity in steam load downcycles. Based on the above assumptions, projected steam sales are as follows: UNIT STEAM SALES PROJECTIONS (Thousands of Pounds of Steam) Total thermal energy requirements Less non-servable requirements Less user needs in excess of waste-to-energy facility capacity (1) Total thermal requirements supplied by plant 186,640 9,885 21,117 155,638 (1) Based on analysis of load cycles and assumption that 5% line losses means that only 95% of the facilities 37,500 pph output can be used to meet load. I --- Municipal Solid Waste Supply--Based on data developed for the Metropolitan Inter- County Association and presented in the Background Study For Solid Waste Master Plans, the seven county metro area was expected to gener~te about 1,991,000 tons of MSW in 1982 or 5,450 tons of MSW per d~y. Ramsey and Anoka counties alone generate some 665,000 tons p~r year of MSW. New Brighton and the communities immediately adjacent to New Brighton (Arden Hills, Columbia Heights, Fridley, Mounds View, Roseville, St. Anthony, Shoreview) produce MSW at an average rate of 400 tons per day or 146,000 tons per year. This production rate is estimated based on the populations of these communities producing MSW at an average rate of 5.24 pounds per capita per day. The proposed New Brighton Waste-To-Energy facility is projected to be able to process 49,275 tons of MSW per year. This is only about one-third of the MSW generated in New Brighton and the immediately adjacent communities and is only about two percent of the MSW generated in the seven county area. I - 6 -
