Againity surpasses new milestone with 60+ ORC turbines
Swedish Organic Rankine Cycle (ORC) turbine manufacturer Againity AB has started 2025 strongly and has surpassed over 60 ORC turbines sold across Northern Europe. Over the past year, Againity's sales have expanded to three new countries – Denmark, Poland, and Romania. Through these projects, heating plants are converted into combined heat and power (CHP) plants, which strengthens their energy efficiency and sustainability.
The demand for robust and weather-independent electricity production is growing, and more and more players are seeing the benefits of converting low-grade heat into electricity with an ORC turbine.
Swedish investments in ORC turbines and battery systems
At home, interest in upgrading heating plants with local electricity production is also growing.
At the end of 2024, Statkraft in Åmål decided to supplement its new hot water boiler with an ORC turbine with a maximum capacity of 400 kW, which corresponds to the electricity consumption of 1,120 small houses with solar panels.
The ORC turbine, the value of which has not been disclosed, will be delivered in July 2025 and is expected to generate approximately 930 MWh of climate-smart electricity annually.
District heating already plays an important role in relieving the load on the electricity grid, and with the installation of an ORC turbine, we are taking another step forward. We will also reduce our production costs, which have become even more important after the dramatic increase in fuel prices in recent years, said Lars Lindskog, Project Manager at Statkraft Värme.
The first order of the year was received from municipal energy company Gislaved Energi AB, which in January 2025 chose to supplement its existing ORC turbine with an additional ORC turbine, this one with an installation of 99.9 kW, and an Againity battery system with a capacity of 500 kW / 1000 kWh.
The solution enables island operation of the heating plant, which means that the plant can continue to produce both electricity and heat even in the event of a power outage.
This gives us increased ability to, for example, handle a sudden power outage to the plant and ensure continued operation of the district heating supply to our customers via so-called island operation. Another added value is that we can offer support services to the power authority Svenska Kraftnät, said Hans Brunström, CEO of Gislaved Energi.
Another municipal energy company, Finspång Teknisk Verk AB, has also chosen to strengthen its plant by supplementing its existing 450 kW ORC turbine with Againity’s battery solution with a capacity of 500 kW / 1000 kWh.
It feels fantastic to work with both returning and new customers who show that they are truly at the forefront of ensuring robust and sustainable energy production, said Elin Ledskog, Sales Manager at Againity.
Strengthen power readiness and new revenue opportunities
By combining ORC technology with battery systems, electricity readiness in municipalities is increased. In the event of a power outage, the battery system can operate the plant in island operation, ensuring that the heating plant continues to deliver district heating.
In addition to increased operational reliability, the battery also enables participation in support service markets and income from so-called arbitrage, i.e., buying electricity when it is cheap and selling when it is expensive, thereby generating additional income while strengthening the economic sustainability of the heating plants.
