An initial assessment of the advantages and disadvantages of utilizing thermal energy from a waste-to-energy facility as a heat source for the developing district heating system in St. Paul is provided. Based on the engineering estimates of total annual costs of a 1000 ton-per-day (TPD) - 10.5 kg/s - capacity resource recovery facility, the required revenues from industrial steam customers, district heating sales and community disposal (tip) fees are developed for a 1986 facility start-up. The economic analysis develops the relationship of disposal fees and costs of thermal energy for district heating for several specific combinations of St. Paul industrial markets, district heating and cogenerated electric power sold to NSP under marginal electric production cost conditions. The results of the preliminary market and systems analyses indicate that, for industrial markets that do not use the total output of a 1000 TDP facility, sale of available thermal energy to the St. Paul district heating utility at costs equivalent to coal-based thermal energy can lower the required disposal fee - or indifference value - compared with a market mix of industrial steam and cogenerated electric power. The political, developmental, environmental, and financial advantages and disadvantages of integrating the district heating market with industrial markets are discussed. The major conclusion of the study is that a moderate amount of district heating market could be supplied from a resource recovery facility at competitive energy costs if facility siting, financing, and integrated marketing of energy products issues could be resolved.
