Name:
Biogas Plant in Trebon

Location (settlement, country):
Trebon, South Bohemia, Czech Republic

Brief description of the technology:
The 1 MWe biogas plant in Třeboň, South Bohemia, is the first Czech biogas plant with significant supply of heat. The plant is situated about 2 km north from the town’s periphery, and the input substrates are pig slurry and energy crops, mainly corn and grass silage (15,5 and 4,3 kt/a).

The special design feature is only a small (175 kWe) cogeneration unit at the spot to cover the electricity and heat self consumption of biogas production, while the majority of produced raw gas is transported by a dedicated 4,3 km long pipeline to the spa facility in the town, where a new biogas CHP plant (844 kWe) was built, which supplies heat to the spa central heating system and an adjacent multi-apartment residential building. Two heat accumulators with total volume of 200 m³ are installed to equalize the daily fluctuations of heat demand. Thanks to this concept, most of the heat generated can be effectively used (over 5 000 MWh/a), and the overall efficiency of biogas energy utilization is over 60% compared to typically only 35% at biogas plants with no heat supply.

The main contractors were MT Energie for the biogas production plant and Stavcent for the CHP plant and the piping. The cogeneration units were supplied by Tedom (the smaller one) and GE Jenbacher.

Financing was covered by a bank loan and a subsidy from EU structural funds (30%). The project received the award “The Czech Energy and Environmental Project of the Year 2009”.

Why is it a „Best practice”:
Thanks to splitting the cogeneration capacity and the installation of a gas piping, energy in biogas can be transported to a longer distance to the location where it could be efficiently utilized. At the same time the biogas plant can be situated out of the town in the centre of fields producing the input substrates.
