Technology-Specific Assumptions<br />
The technology-specific assumptions comprise assumptions for domestic boilers, industrial boilers and for the CHP<br />
turbine. The assumptions for these technologies are outlined in Tables 5, 6 and.7.<br />
Table 5: Domestic Boiler Assumptions<br />

In an attempt to represent the market segment of biomass boilers in commercial buildings, small industry and<br />
institutions, a comparison was furthermore made between a 100 kW wood chip boiler and a conventional natural gas<br />
boiler or an oil fired boiler. The assumptions regarding investments (including subsidy) and maintenance costs are<br />
shown in Table 6.<br />
Table 6: Industrial Boiler Assumptions<br />
Parameter Unit Wood Boiler ( 1 ) NG Boiler ( 1 ) Oil Boiler ( 2 )<br />
