Cogeneration/district heating plants equipped with condensing-tail turbines and full-sized heat rejection systems cost approximately 3% more than comparable sized electric-only plants. Bus bar electricity costs of cogeneration plants are comparable with those of an 800-MW(e) electric-only plant. The cost of bus bar electricity is practically independent of the two sites evaluated, but the heat delivered to the load center from the Coon Rapids site is 30 to 50% more costly than the heat delivered from the High Bridge site because of the greater transmission distance from the Coon Rapids site. The cogeneration plant operating at its assigned capacity factor will provide heat and electricity at the plant boundary at significantly less cost than will separately sized heat-only and electricity-only plants because of (1) better fuel utilization, (2) common use of facilities, and (3) the sale of two products - heat and electricity.
