Vänerenergi AB invests just over SEK 1.8 million on renewable electricity production in the heating plant in Töreboda. In the spring of 2019, the heating plant will be supplemented by an & nbsp; ORC turbine.
– This is a good investment for the environment, says district heating manager Kjell-Åke Wallström.

During spring 2019, the VänerEnergi will install an ORC turbine to the hot water boiler at Töreboda heating plant. The technology is based on the Organic Rankine Cycle (ORC), which allows low-temperature heat flows, in this case 105-degree hot water, to be used to extract electricity.
One of the major advantages of being able to produce electricity while producing heat is that electricity is produced when we need it the most, that is, especially during the winter,” says Kjell-Åke Wallström, district heating manager at VänerEnergi.
On an annual basis, approximately 210 MWh of electricity will be produced at the plant, resulting in annual emissions savings of 180 tonnes of carbon dioxide equivalents when replacing European marginal electricity. The ORC turbine will be the eighth of which the Norrköping based company Againity AB delivers, where the majority of turbines are instaslled to biomass fueled hot water boilers.
Although we have an increasingly urgent need for weather-independent electricity generation in our energy system, turbines are still missing in more than 400 Swedish district heating plants,” says David Frykerås, CEO of Againity. ”We are pleahappy to see that VänerEnergi is at the forefront and chooses to upgrade its heating plant to CHP.”
The installation corresponds to two pipes from the boiler circuit, two pipes from the district heating system and a power cable. With minimal maintenance and low manufacturing costs the installation will be profitable despite the relatively low electricity prices on the Swedish market.
The heating plant in Töreboda is located in the area of Moelven’s laminated wood factory and the residual products are delivered via transporters directly from the laminated wood factory to the heating plant. In addition to the boiler, the heating plant consists of a cutter chip that is also fired by a wood-fired boiler and a bio-oil boiler that can be started up quickly if one of the solid fuel boilers falls out. The district heating supply, which is 100% renewable, amounts to about 28,000 MWh / year, which corresponds to the annual consumption of hot water and heat in approximately 1,400 normal-sized villas.
Since spring 2017, over 700 people have visited the ORC system which Againity has delivered to the district heating plant of Bräkne-Hoby. Do you also want to come and have a closer look at an ORC system? Look out for the next demonstration day on our website or contact us at info@againity.com or +46 (0)705-29 32 23.
Againity has been appointed to have one of Sweden’s smartest energy innovations! Today, 4 billion people put their waste in nature and the majority of our energy comes from coal and oil. If you want to vote in the competition, click here.

Visitors during study visits at Bräkne-Hoby’s heating plant in the fall of 2017.
Arne Andersson at Ronneby Miljö & Teknik talks about his experiences with Againity’s ORC turbine.
Againity has developed a technique for converting low heat to electricity. The technology resembles that of conventional steam plants, but is based on a so-called Organic Rankine Cycle (ORC). Againity has succeeded in scaling down the technology with sustained cost-effectiveness, and is today the market leader in ORC systems with an output of less than 400 kW. The technology enables smaller heat plants to be easily upgraded to electricity generating CHP plants.
The Swedish Energy Agency has granted Againity AB a project support of SEK 8.6 million. The company will further develop and scale up its customized turbine solution for the conversion of heat to electricity.
E.ON is committing to sell renewable and recycled energy only in 2025 and highlights Againity’s ORC turbines as part of the solution for a more sustainable energy system.

With an Againity ORC turbine the biofuel from local forests will be transformed into green electricity at Örkeljunga heating plant. The turbine’s capacity of 250 kW electricity corresponds to the average need of 440 villas or the effect of 18,000 m2 of solar PV panels, with the important difference that the turbine produces the most electricity in the winter when demand and spot prices are highest. Climate savings correspond to more than 1000 tonnes of carbon dioxide equivalent per year when replacing European marginal electricity.
We are happy both to be able to make a financially good investment, for the environmental gains and not least to be part of leading the development forward,” says Stefan Jacobsson, CEO of Örkelljunga Fjärrvärmeverk AB. ”The owners, board and management are all united behind the investment decision.
Örkelljunga district heating plant has two wood chip boilers of 7 and 3.5 MW that together produce around 35 GWh of heat per year. The ORC turbine will be installed in autumn 2018 and will be Againity’s seventh installation in Sweden.
We are pleased to get the opportunitiy to deliver a 250 kW ORC to Örkelljunga district heating plant,” says David Frykerås, CEO of Againity AB. ”It’s great to see that several district heating plant invests in ORC technology after we have now had a number of machines in operation that demonstrated high availability and stable production.
Örkelljunga heating plant orders a 250 kW ORC turbine from Againity AB. David Frykerås, CEO of Againity, (left) and Stefan Jacobsson, CEO of Örkelljunga Fjärrvärmeverk AB, (right) look forward to increase the share of renewable electricity generation in Sweden.
