Farm Power Supplies Local Renewable Energy from Small-scale Producers

Farm Power production by PV at Itikka Farm, Northern Savo, Finland

Farm Power by Oulun Energia Ltd. is a local energy from Finnish small-scale producers. Farm Power electricity is generated using micro and small scale generating plants used principally for generating electricity for the producers’ own needs. When generation capacity exceeds the producer’s own demand, electricity is sold to the grid. Farm Power is the winner of annual Climate Award, Ilmastoteko, in 2014.

Producers of Farm Power electricity are committed to the use of renewable sources of energy, such as wood, hydro, wind and solar power. External experts certify the metering, calculation and tracking procedures used in the production of Farm Power.

Annual net metering of the Farm Power allows producers to utilise their full production capacities and provides a possibility purchase the produced surplus back later on. Farm Power differs from other energy products as every producer can set the price of electricity they generate to the grid.

Farm Power is a concept supporting the market access of micro- and small-scale renewable energy. Market access paths of RE and energy storage technologies are investigated in detail in the GREBE project.

Sinikasvis – Biomass-based CHP and PV at farm-scale

Sinikasvis image 09-06-2016

Sinikasvis is a limited partnership located in Sukeva, Northern Savo. The berry farm has unique energy production system consisting of a biomass –based co-production of heat by Spanner Re2 unit and 15 kW PV system.

The Finnish GREBE partners, LUKE and Karelia UAS, visited Sinikasvis for compiling a case study for the GREBE project on biomass-based CHP. The recently invested system, Spanner Re2 (30 kW for electricity, 80 kW for heat) is the first of a kind in the region, but has number of references around Europe. The energy consumption (140 000 kWh/a) is highest in winter peak times, but also in late summer as berry farm needs energy for freezers and dryers. The woodchips are high quality (below 10% moisture and even-sized) and produced by the farmer form his own forest.

Sinikasvis is part of the E-farm network demonstrating renewable energy solutions in Finland. The farm is also producer of Farmivirta – Farm Power – concept of Oulun Energia, selling renewable electricity produced by micro- and small-scale producers.

The GREBE project will prepare a case study report about the Sinikasvis farm, which will then be available as good example case for biomass-based CHP solution for the Northern Periphery regions and GREBE partner countries.

Hybrid energy solution on farm scale – Finnish GREBE partners visited a case in Northern-Savo

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.
