Performance The screw-engine has been in almost continuous operation between November 2003 and May 2004. Under the monitoring period, the data for the calculation of efficiencies where collected. The overall net electric efficiency of the CHP plants amounted to about 10 % and the thermal efficiency was measured to 70% giving an overall efficiency of 80%, [27]. Economic Evaluation An economic evaluation was made by Hammerschmid, [24]. The surplus specific investment costs for the CHP plant amounted to 3750 €/kWel and the COE was calculated to 138 €/MWhel. This may be considered a reasonable cost for a demonstration plant of this size. Table 2.9 Economic data for the Hartberg plant Investment Specific investment CHP Annual operation hours Fuel price Economic lifetime Interest rate COE 2.2.3.

With a COE of about 133-138 €/MWhel the steam engine is not the most economical solution, but it has one advantage over the other technologies, the possibility to deliver process steam. This makes the steam engine very suitable for cogeneration in for example a saw- or pulp mill. If such a plant would be erected, the COE would decrease since the annual operation hours of such a plant would probably exceed 6000 hours per year. 26PDF Image | Biomass Based Small Scale Combined Heat and Power Tech
