The Finnish GREBE project partners Luke and Karelia UAS visited Itikan tila farm in the region of Northern Savo in Finland. The farm visited will be a case study for the GREBE project on hybrid energy solutions used in energy production.
The farm is a seed producer since the 1970´s, but the ownership dates back until 1905, however, nowadays energy production plays an important role of the farm´s business. The energy production on the farm includes an own biodiesel production unit, a wind turbine, solar panels and a ground source heat pump.
The bio-oil production is used mainly to produce heat for heating and drying of grain, but also as fuel for two tractors and a harvesting machine. The production is based on rape seed oil and vegetable and frying oils from the industry in the region. The rape residues can be processed to briquettes as cattle feed on the farm. Briquettes are also produced from straw, cutter shavings and saw dust from the local wood processing industry and mainly used for combustion in a municipal district heating scheme in the region.
The hybrid energy solution for the farm includes a 5 kW wind power plant since 2015. The energy produced is used to heat water in an accumulator. In addition to the energy production, the wind mill is an important component for the demonstration.
The farm has invested two years ago into a solar PV plant with a capacity of 10 kW. The produced electricity is transferred directly to the electricity grid. The farm used heat exchangers and heat recovery systems in many places on the farm, LED lights are the favored light option.
Another energy source is based on a ground sources heat pump system (30kW). All in all, the farm has an energy consumption of approximately 150 000 kWh, especially for seed processing and drying.
The farm is also part of the e-farm network which for example organizes visits to energy producing farms. The Itikan farm has several visitor groups each month.
The GREBE project will prepare a case study report about the Itikan farm which will then be available as good example case for hybrid energy solution for the Northern Periphery regions and GREBE partner countries.
