Trash Incineration is the Most Expensive Way to Make Energy

The vari­able oper­a­tions and main­te­nance (O&M) costs are as follows:

Vari­able O&M costs include fuel and oth­er con­sum­able mate­ri­als and sup­plies; raw water; waste and waste­water dis­pos­al expens­es; pur­chased pow­er (incurred inverse­ly to oper­at­ing hours), demand charges and relat­ed util­i­ties; chem­i­cals, cat­a­lysts and gas­es; ammo­nia for selec­tive cat­alyt­ic reduc­tion (SCR), as applic­a­ble; and lubricants.

To sum­ma­rize the EIA table in the charts above, we did the following:

  • Bio­mass: used the bub­bling flu­idized bed type, since com­bined cycle requires gasi­fi­ca­tion and bio­mass gasi­fi­ca­tion is high­ly unusu­al (most are con­ven­tion­al boil­ers or flu­idized bed)
  • Coal: this is an aver­age of sin­gle and dual advanced pul­ver­ized coal (the tra­di­tion­al sorts of coal plants that can no longer be built in the U.S.)
  • Geot­her­mal: took the aver­age of the two types
  • Hydro­elec­tric: includ­ed only con­ven­tion­al and not pumped hydro­elec­tric (nei­ther of which tends to be proposed)
  • Nat­ur­al Gas: this is an aver­age of con­ven­tion­al and advanced com­bined cycle (the typ­i­cal plants built, since com­bus­tion tur­bines and fuel cells are not com­mon­ly proposed)
  • Solar pho­to­volta­ic: this is an aver­age of large and small

Map of Coal and Gas Facilities

We are mapping all of the existing, proposed, closed and defeated dirty energy and waste facilities in the US. We are building a network of community groups to fight the facilities and the corporations behind them.
