The efficiency of small, modular plants is only two-thirds as great as that of a large, field-
erected plant because the smaller plants use a smaller turbine generator, have lower carbon
burnout, have higher radiative heat losses, and operate at lower heat transfer temperatures (see
Appendix A , page A-24). The average net electricity production, in kilowatt-hours per ton, is
also two-thirds as great for a modular plant as it is for a larger plant (see Appendix A,
Attachment 11, pages 11-4 and 11-5; also Berenyi and Gould, 1991a). Most of the small,
modular plants have been designed for steam production only.
Cost data for mass burn facilities are summarized in this subsection. More detailed informa-
tion is provided in Exhibit I.
Mass Burn: Field Erected
Most field-erected mass burn plants generate electricity only. The average size of the 68
facilities for which useful data are available is 1,200 tons per day of design capacity (with a
range of 750-3,000 tons per day). Figure 5.2 summarizes the capital cost estimates for the 68
electricity generating plants.* The average capital cost is $106,000 per ton per day of design
capacity, with a range of $30,000-$210,000.
In some'"tudies, facilities were not differentiated by the form of energy produced; instead,
all field-erected mass burn units were grouped according to the calendar years in which con-
struction began and ended. The capital costs reported in those studies range from $21,000 to
$114,000 per daily ton of design capacity (Kiser, 1990).
Figure 5.3 shows the O&M cost estimates for the electricity-only mass burn plants for which
data are available. The average O&M cost is $26.50 per ton of MSW processed, with a range of
$9 to $48 per ton. Figures 5.4 and 5.5 provide estimates of capital and O&M costs for 20
steam/electricity plants. Exhibit I also provides data on plants that produce steam only. Capital
costs are lower for those facilities than for electricity-producing plants, but O&M costs are not.
Mass Burn: Modular
Figure 5.6 summarizes the capital cost estimates for 11 modular steam and electricity
generating plants that have an average capacity of 243 tons per day. The average capital cost is
$95,100 per ton of design capacity per day.
Figure 5.7 shows estimated operation and maintenance (O&M) costs for the modular plants
for which data are available. The average O&M cost for the facilities is $32 per ton of MSW
processed, with a range of $21 to $42 per ton. Exhibit I presents costs for 34 modular mass burn
plants that produce steam only, and for 4 plants that produce only electricity. In general, the
steam-only plants are smaller in capacity than those that produce electricity. The average capital
costs are lower for the steam-only plants, but the O&M costs are not. Tipping fees average
$49.79 for the steam/electricity plants, and $25 for the steam-only plants.
* To standardize the presentation of costs, all published estimates have been updated to a mid-1991 time frame us-
ing SRI International's PEP Cost Index. Unit capital costs and O&M costs are presented in dollars per ton of
MSW as collected. If information on individual cost items was unavailable in the literature, estimates based on
reasonable assumptions were used. The bases for the data are described in detail in Exhibit I.
