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.
