Small scale CHP Life+

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

Between 2014-2020, three different techniques for small-scale electricity production of biomass-based cogeneration have been 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.

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

Conference participation 2020

Daniella Johansson, projektledare på Energikontor Sydost presenterar projektet Småskalig kraftvärme.


The results of the Life+ project Small Scale CHP was presented for 50 attendees at a webinar arranged by the BIOCOGEN 2030 platform, on July 7th 2020. You can find the recoding of the webinar and the presentations for downloading here:  


The aim of the webinar was to give a chance for CHP (co-generation of heat and power) projects and companies to present their CHP solutions and enlarge the network of the BIOCOGEN 2030 platform. The webinar was held as a side event to the European Biomass Conference and Exhibition that was moved to a virtual platform to cope with the COVID 19 emergency.  



Small scale CHP Life+ presented at the Central European Biomass Conference

On January 24, experiences from our small-scale chp project were presented at the Central European Biomass Conference in Graz. The conference is held every other year and attracts researchers, entrepreneurs, politicians and suppliers who share a common interest and knowledge in bioenergy. This year, the conference was held between 22 - 24 January 2020 , attracting a total of 1,500 participants.

In addition to disseminating our knowledge of small-scale cogeneration in the southeast Sweden and Sweden in general to those attending the lecture, all conference participants also received information in the form of an abstract from all lectures being presented at the conference, including that of the Energy Agency of southeast Sweden and the Life+ project Small-scale cogeneration from bioenergy.


Attending the conference also provided knowledge of the situation and trends of bioenergy in Europe. Above all, our project manager Daniella Johansson got to meet and talk to suppliers of small-scale gasification technologies that are not yet available on the market in Sweden.

Project background

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.

Plants for small-scale Combined Heat and Power production are built in Southeast Sweden for demonstration of techniques.  Project runs from July 2014–December 2020.
With support from the Swedish Energy Agency, EU financial instrument Life+ and Energiföretagen Sverige.
