Forest and dairy farm Kauppi, located in Petäjävesi central Finland reduces its carbon footprint for future generations. The income from the renewal of a 90 years old spruce forest was invested into a biogas vehicle and to a 16.8 kilowatt photovoltaic system. The investment to photovoltaic system was also partly financed by the Finnish Centre for Economic Development, Transport and the Environment. This was done because owners of the farm value renewable energy and with these improvements the energy self-sufficiency will be high.

The Kauppi farm is owned by two siblings with their families. The farm has been inhabited by the same household since the 18th century. Their fundamental values are continuous and sustainable development of the farm for future generations. When the renewal of the 2.8 hectare and 90-year-old spruce forest became topical, the family discussed about ways to decrease carbon dioxide emissions.

"We are considering both carbon footprint and energy self-sufficiency. We are well aware of the importance of forest to the climate change mitigation. Forests must be tented well and renewed time to time to achieve the best growth. This is done because the growth of old forests is slowing down. In old age forests will be more vulnerable and its carbon capture capacity will deteriorate in long term" says Mikko Tiirola, one of the owners of the farm.

Tiirola knows what he's talking about. He is a forest owner but also a certified forest manager, as well as chairman of the Central Union of Agricultural Producers and Forest Owners’ (MTK) Forest Delegation. Everyone in the family wanted to invest the wood sales revenue back to the farm. Finally they decided to invest into a biogas car and to a 16.8 kW photovoltaic system.

"I calculated that 1400 tons of CO2 stored in forest residues will be converted into biogas and solar energy to replace fossil carbon. Furthermore, most of the carbon bound to the wood will continue to be stored in the harvested wood products as more than 90 percent of the harvested wood will be used as log wood", Tiirola sums up the environmental impacts of the project. The 16.8 kW photovoltaic system reduces the annual carbon dioxide emissions by about 2,500 kg. This corresponds to an average annual amount of carbon sequestration of 115 trees. Kauppi farm received a 40 percent investment support from the ELY Center for the solar power system.

"The biogas car was a principle choice. One car does not change the world, but we wanted to change the direction in our own consumption. The same applies to the photovoltaics. The 16.8 kW photovoltaic system improves our self-sufficiency significantly and solar is the cleanest energy available. Our goal is to generate 20 percent of the annual electricity demand on the roof of our own machinery warehouse" adds Tiirola.


Naps Solar System to Kaupin tila

The Naps photovoltaic system consist of 56 pieces of 300 watt Naps Saana solar modules. The system was delivered by Kotiwatti Oy, a Naps Solar authorized partner.
