Power from Biomass project final seminar, Monday 11th June, Joensuu


The Rural development programme co-financed Power from Biomass project completed its work in June 2018 after three years of renewable energy development in North Karelia, Finland. The project cooperating closely with GREBE in North Karelia, resulted in several new investments including two solar PV and energy storage systems in community buildings of Höljäkkä and Haikola in Nurmes. Project also established a regional network of 15 renewable energy demonstration sites.

The final seminar held in Joensuu, presented projects main outputs, latest developments in renewable electricity production, biomass-based small-scale combined heat and power, solar energy project of heat enterprises, and intelligent solar PV systems.

Project manager Antti Niemi from Pielinen Karelia Development Company PIKES Ltd. summarized the project results. The project established a regional demonstration network with 15 sites demonstrating renewable energy production systems. The Energiaraitti website presents the technical and economic information and live-information of solar PV systems. New production units established were mostly solar PV and some energy storages systems in farms, other rural enterprises and community buildings. The biomass-based renewable energy had a challenging business environment due to low price of fossil fuel oil. Despite, also some new biomass-based energy systems were established.

Project manager Kim Blomqvist from Karelia UAS presented the solar PV systems integrated into biomass-based district heating plants. Investments were made for 7 district heating plants with total annual production of 52 MWh. The heating plans were considered suitable for the solar PV as they have balanced electricity demand.

Marketing and product development manager Kimmo Tolvanen, representing regional energy company PKS, presented an in-depth overview of the energy system development in Finland and North Karelia. The main game changers in the energy system are expected to consist of wind and solar power production, energy storages and digitalization working all effectively together. The energy grid changes toward decentralised, intelligent and adaptive systems are evident. In addition, electricity markets are in transition, and new service developments are expected throughout the system from production to consumption.

Project coordinator Anssi Kokkonen from Karelia UAS presented the technical solutions of biomass-based combined heat and power production. The solutions included woodchip gasification plant (Volter Ltd.), Nano-chp Stirling engine (9 kWth + 0.6 kWe), fuelled by wood pellets (Ökofen).  Both solutions are demonstrated at Sirkkala Energy Park by Karelia UAS.

Project manager Toni Hannula from energy company ESE (Etelä-Savon Energia, Mikkeli) presented intelligent solar power systems. The smart energy transition project by Lappeenranta Technological University has generated an overview of the systems change. The ESE has been successful in establishing biogas fuel stations, and piloting intelligent solar PV systems with 48 hours production forecast and directing the production optimally depending on energy price (electricity spot-price optimizing) and production and consumption loads. The system is piloted in Lumme Energia Oy estates.

The Power from Biomass project developed as a diverse renewable energy project and delivered several new services and RE production sites were established. The project had an international element through cooperation and networks of the GREBE project.


First Ökofen Pellematic Condens_e CHP-unit in Finland

KUAS 04-11-2017 (1)

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.

GREBE Reports on Technology Case Studies

Wavenet - page 4

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:
