In this feasibility study a fuel switch from fuel oil for wood-chips (0.4 MW in-house heat-only boilers) is assessed techno-economically. The assessment is made by and based on default investment, cost and price figures of the “B4B BioHeat Cost Calculator”, developed within the project Bioenergy4Business (B4B). The study is based on a real fuel switch, which took place 2014 in an Austrian hotel, as the oil boiler has reached his end of service life.
This pre-feasibility study compares the economic efficiency of a natural gas fired with a wood-chip fired district heating plant. The district heating plant has a peak heat load of 4.9 MW and supplies 10.6 GWh/a heat (sold energy) to 94 heat consumers. The grid has a trench length of nearly 8 km (and a pipe length of nearly 16 km). The economic assessment is performed by means of the “B4B BioHeat Profitability Calculator”, developed within the project Bioenergy4Business (B4B).
The study is based on a real wood-chips fired district heating plant, where construction work in a Tyrolean village started in April 2013. It was put into operation in October 2013 and was finalized in November 2014. In this report the project is assessed again, under current situation, i.e. construction start in 2016 and start of operation at the beginning of 2017.
