Thermal energy frnm the r~vaste heat recovery cycle ~vauld be used <br />for school heating purposes. Excess power (electricity) would be sold to Duke E;nerg}~ <br />under a parallel generation agreement. <br />Major components of the system include: gas extraction. wells and collection system <br />(South Eubanks MSWLF), blo«rer and flare statioxl (South Eubanks MSWLE), moisture <br />removal and gas compression station. (South Eubanks MSWLF site), gas transmission <br />line to elementary schnol, fuel conditioning and rnicroturbine system (elementary school) <br />and power grid intertie and protective relay module (elernentar}J school). <br />The results of a 3U-year, life-cycle .cost analysis for this option are summarized in <br />Table 3. <br />Table 3 <br />ECONOMIC 1~VA1..llAT1{~`J <br />(Annual Average Cost) <br />Energy Sales & Avoided Costs $1b8,100 <br />Energy Production Costs $27'b,700 <br />Net Energy Vattae {$t08b00) <br />Net Present Worth {$t,5b5295) <br />PasEd LipUil the preliminary energy demands of the primary users, the Eubattl:s Rnaci <br />Cogeneration Project does not appear to be econnmicaliy acivantagenus at tills time (i.e., <br />tl~e estimated energy costs are projected to exceed the total energy sales secs avoiclerl <br />casts.} 1-lowever, it should be noted that the design consultants for the. elementary school <br />and animal shelter slave been requested to review aid ctpciate energy denla~ld assurnptians <br />based upon more del`ined building program requirements.
