Biomass Energy Plant from Vatra Dornei
Topic of the practice
Renewable energy utilisation.
Good Practice Information
Vatra Dornei is situated in Suceava County which is a mostly mountainous region with great areas
covered by woods. Its population is approximately 16,500. The woods cover 58% of the total county area as compared to an average of 28% at the national level. In the area there are numerous companies whose object of activity is wood exploitation and processing. In these conditions, the biomass resources are abundant. Much of the town itself was supplied by 6 old and worn out oil-fired District Heating systems. The town applied to take part in the national 'Sawdust 2000' investment strategy programme (carried out in co-operation with Denmark) whose aim is to increase the use of sawdust and other wood wastes as a fuel source. Under this scheme the old system has been replaced with 2x6MW sawdust-fuelled boilers and 1x 6MW petroleum derivatives-fuelled (back-up) boiler. The annual sawdust consumption amounts to about 17,300 tonnes, the resulting ash representing 1% of input. As part of the project the district heating network (11km) was also rehabilitated from the boiler room to consumers. The new thermal plant supplies 1,500 apartments, several public institutions (a school, a kindergarten, a crèche, a children’s home, four medical offices) three hotels accommodating 900 people, 2 treatment bases. The total cost of the project amounted to EURO 4.5 million:
- 36 % from the EU through the PHARE Programme
- 29 % from the Danish Government within the Joint Implementation System
- 25 % from the state budget
- 10 % from the local budget
Evidence of success
From the social point of view, the project has ensured the supply of hot water and heat 24 h/day for 40% of the town population at low prices and without requiring any subsidies from the budget. From the ecological point of view the project has reduced annual GHG emissions by 9,400 tonnes CO2 equivalent. 80% of this reduction resulted from reduction in the wood waste amount left in the forests whose anaerobic digestion produces methane. From the energy efficiency perspective, the project has enabled the rehabilitation of a district heating system (heat production source and distribution networks), whose heat losses had been estimated at about 50% of energy input, replacing it with a modern, high efficiency, low loss scheme.
