Small scale CHP Life+

Different techniques for small-scale combined heat and electricity production.

Between 2014-2019, three different techniques for small-scale electricity production of biomass-based cogeneration will be built and demonstrated in southeastern Sweden as part of the project Small Scale CHP LIFE +. 
Partners of the project, where the demonstration plants are built, are Emå Dairy in Hultsfred and Ronneby Environment & Technology AB. There is also collaboration with Linnaeus University, Bioenergy Group, Svebio, Swedish District Heating and Energy Agency in order to study the possibilities for small-scale combined heat and power from a systems point of view.






Project objectives

This project will demonstrate different small-scale biomass CHP technologies. The aim is to pave the way for a broader application of biomass CHP technology. The knowledge gained will be disseminated on a regional, national and European level.

The main project objectives are to

• demonstrate the technologies at small-scale biomass-based CHP plants that will be built in in Southeast Sweden;

• promote the use of, and a business model for, small-scale biomass-based CHP technology at the regional, national and Europe level; and

• increase the production of renewable electricity by promoting local small-scale biomass-based electricity production.


Combined Heat and Power (CHP) technologies based on biomass combustion have great potential to reduce CO2 emissions because they use renewable energy sources, such as wood fuels or sawdust. Typical fields of application for biomass CHP plants are wood processing industries, sawmills, district heating systems and industries with a high process heat and cooling demand. Inorder for CHP plants to operate in a way that is economically and ecologically beneficial, both the electricity and the heat produced must be used.

CHP technology is already available on Swedish and European markets. Due to the high installation costs, and a lack of information about its efficiency, the technology is, however, currently not widely used in small-scale plants. Extensive research has been undertaken to illustrate the vast environmental potential of CHP technology but a larger initiative that looks at increasing market application is still needed.

Expected results

• Greater knowledge about the environmental performance of biomass-based CHP technology.

• Increased use of biomass as a renewable fuel.

Results so far

  • Three small scale combined heat and power plants are built, demonstrating three different techniques; WST, ORC and a gasifier.
  • Study visits are offered and the goal of 900 visits to the three plants are reached.
  • 15 ORC:S has been installed at different plants in Sweden since the start of the demonstrations, all companies have been at a study visit to the ORC demonstration plant.
  • A handbook has been produced, focusing on the planning process. An update including data from the plants will be produced.
  • The plants has generated a lot of interest from media resulting in over 60 articles.
  • The project has been presented at over 30 conferences nationally and internationally



Partners and techniques



Emå Dairy is a local producer of milk and dairy products in Hultsfred. The plant is owned and run by the farmers themselves. They have a strong local and environmental profile with their slogan "Milk from your area". They have installed a gasification plant where the wood is converted into heat and electricity. Read more







Ronneby Miljö & Teknik AB is a municipal corporation, wholly-owned by Ronneby municipality. They manage power, heat, water, sewage, sanitation, fiber optic networks and broadband. Their goal is to combine environmental responsibility with economic efficiency. They are currently building a facility for wet steam, a steam turbine for electricity production on the existing district heating plant, Sörbyverket. Read more

The company have also installed an ORC (Organic Rankine Cycle) at the district heating plant in Bräkne-Hoby. Read more
