The CHP project of Kuittila Power was initiated by the entrepreneur/farmer interested to decrease the energy costs and produce own energy for the farm and co-located company. One of his staff and a development company introduced the solution. The reference site and a manufacturer were visited, after which a feasibility study was carried out.
As there was positive result, the investment project was initiated and 35% co-financing negotiated from the local authority. The manufacturer provided the technical planning, and investor took care of micro DH network construction and required connections (with the electricity company). A local constructor made the building construction.
The investment initiated in April, was ready in October 2012. The first winter included only test-runs, as there was no available high quality wood fuel. In spring, own fuel supply (with dryer solutions from the reference site) was established and plant started operating.
The first year included technical operations to improve the performance; technical support was received through the manufacturer. The plant is operating now a 3 year at a roll, and received significant status of small-scale CHP demonstration in the region, nationally and internationally.

The first Ökofen Pellematic Condens_e CHP-unit in Finland has been installed to Sirkkala Energy Park at Karelia University of Applied Sciences. The nano scale CHP (combined heat and power) unit produces energy with a condensing pellet boiler and an integrated Stirling engine. The whole unit requires only 1.5m² of floor space. The CHP unit is installed as part of Sirkkala Energy Park’s hybrid energy system that produces heat and electricity for Energy Park and for two elementary schools. This CHP unit is already connected to Fronius Symo Hybrid inverter, which will be connected to a small array of Panasonic HIT pV -panels. When battery storage is added to this system it will be a true standalone system.
Ökofen Pellematic Condens_e CHP-unit is designed for 6mm pellets, but it will run with 8mm pellets. The unit has a nominal thermal output of 9kW and 600W of electricity, but it can modulate the production between 3-13kW thermal and up to 1kW electricity. Unit size is ideal for single houses and requires only a little maintenance, just some brushing and vacuuming for pellet boiler and heat exchangers. The Stirling engine is nearly maintenance free.
With the Pellematic Condens_e it is possible to generate electricity and heat for your own consumption. Economically, at least in Finland, the electricity generated should primarily be used at home and only the excess available electrical energy should be fed back into the public electricity grid.
The Integrated Microgen Stirling engine produces AC power at 50Hz from the thermal energy the pellet boiler produces. The electricity production is based on a thermal gradient, so the efficiency is dependent on the temperature difference of returning water flow from the hydraulic heating circuit. The cost of the unit is approximately €23,000, excluding the possible requirement for hydraulic components or larger-scale fuel storage.
Many regions of the NPA have some of the best renewable energy resources; however in many cases they are not being effectively exploited. The Case Studies aim to address this by the assessment of a range of renewable energy technologies to determine the drivers and barriers for their transferability to other areas in the NPA where the same renewable energy resource are available but are not widely exploited.
The Case Studies exemplify how, through the proper identification of appropriate and scaled technological solutions, renewable energy resources in each partner region, can meet the demands of energy markets. The technology case studies were informed by engagement with technology providers and other relevant stakeholders. The focus of the case studies is on technological choices (details of how these operate, innovations etc.), funding mechanisms, processes of delivery and adaptation in different partner regions, assessment of technical and financial risks, and demonstration/piloting routines.
The case study collection provides evidence and data on important drivers and barriers and an in-depth analysis of the Renewable Energy technologies feasibility prospect to be transferred across partner regions. The case studies cover technologies, market access and business growth paths.
These cases studies are based on the following technologies:

The Finnish GREBE project partners Luke and Karelia UAS visited two E-farm® destinations provided by the Finnish E-farm® service using renewable energy solutions for energy production on a farm scale.
A perfect example for an E-farm® destination is the Itikan tila farm in the region of Northern Savo in Finland. The farm produces agricultural products, provides cultural and tourist services and has an own energy production on the farm including an own biodiesel production unit, a wind turbine, solar panels and a ground source heat pump.
The E-farm® service includes site visits to so-called “E-farm® destinations”, support services in form of calculations, education and training. E-farm® offers for instance dedicated courses on biogas and wind energy. Also, E-farm® provides detailed investment calculations and support for farmers planning to invest in renewable energy solutions on their farm. By contacting the coordinator of E-farm®, customers can order visits or tours to any of the destinations in Finland, ask for support or other offered services at one contact point. Also tours to Central Europe can be organized. Companies behind the trademark are Envitecpolis Oy and Savon Siemen Oy.
The concept of combining conventional (farm) business with energy production and tourism has been presented in the Northern Periphery Programme (NPP) area before, the NPP project REMOTE worked with this idea for example. Besides of the availability of sustainable resources, the Northern Periphery area is unique in regards to the high number of remote dwellings in rural areas, the availability of unique cultural experiences and events for tourists. A large share of buildings has either no access to electricity or is dependent on producing energy from fossil fuels. A focus was to provide feasible solutions for renewable energies in remote areas adapted to the scale of sparsely populated areas and communities by providing information, products and services similar to the E-farm® concept especially dedicated for farms and their customers.
E-farm® has a network of farms across Finland coving a wide range of renewable energy solutions including for example wind mills, small scale CHP units from forest chips, biogas, biodiesel, solar panels, hydro power and ground source heat pump.
In addition to energy sales of renewable energy to the market, visits to the farms provide new business opportunities such as additional income to both the farm and the service and increase the awareness and experiences of energy production investments at farms.
