One of the successful examples of such replacing is company “Camellia”, which is engaged in growing flowers in an 11 ha greenhouse. Established in 1994, the company used to consume natural gas for heat production that accounted for 45% of production costs in the cost price of grown flowers. When the price of gas started rising (2013) the company decided to switch to biomass (<5% of production costs in the cost price of grown flowers).
“Camellia” installed 2 x 3.5 MW boiler on wood chips/agro-pellets. Gas boiler remains as a standby equipment. Heat production of the biomass boiler plant is 58 GWh/yr. Average price of heat is 40-50 EUR/MWh. Annual amount of biomass fuels needed is 25 kt/yr (fresh) or 70,000 MWh.
Among the advantages of such project is that a reliable local equipment provider has been chosen, and the consumer is located in the area with sufficient biomass resources available. Biofuels and biomass are purchased from local producers in the form of wood chips, stem wood and straw pellets. “Camellia” is interested in further implementation of bioenergy technologies.
