Full house when “new” CHP plant in Moheda opened up for visitors

There was great interest when Alvesta Energi AB arranged an open visit at the newly upgraded cogeneration plant in Moheda.

During the open visit, participants from all over the country had the opportunity to ask questions and learn more about Alvesta Energy’s new ORC turbine. The turbine enables local electricity production using hot water from the existing boiler which is fired with local wood chips, a residual product from the sawmill at the neighboring property.

Mats Karlsson, CEO of Alvesta Energi, talks about the company’s vision of a better environment.

It was during the fall of 2019 that the ORC turbine was installed and commissioned at Moheda heating plant, which made Alvesta Energi first in the region of Småland with a small-scale cogeneration plant. The investment will result in 170 MWh of electricity generation per year in addition to the heat already produced for the district heating network in Moheda.

We see the investment in the ORC turbine as a step going from heat production only to combined heat and power production, using local biomass in a cost-effective way in our heating plant in Moheda, says Mats Karlsson, CEO of Alvesta Energi AB. This allows us to contribute to small-scale, local and weather-independent electricity generation to our common electricity grid.

Today, more than 400 heating plants in Sweden still lack electricity generation, but more and more energy companies are choosing to follow in Alvesta Energy’s footsteps and upgrade their heating plants to cogeneration plants – an investment with both environmental and economic benefits.

We are happy that Alvesta Energi chooses to be at the forefront, showing that also smaller heating plants can contribute to renewable baseload power, says Elin Ledskog, sales manager at Againity. Together we can be part of this necessary transition to a more energy-efficient and climate-smart future.

Elin Ledskog, Head of Sales at Againity, describes how the new ORC turbine can produce electricity from the hot water boiler at the heating plant.

Solör Bioenergi invests in two additional ORC turbines for green power production

After last year’s turbine installation at the heating plant in Hörby, Sweden, Solör Bioenergi now chooses to provide two more of their heating plants with ORC turbines for local electricity production from biomass. This time at the slightly larger heating plants in Svenljunga and Vilhelmina.

Nicklas Eld, Regional Manager Solör Bioenergi Väst, looks forward to more green electricity production at Solör Bioenergi’s facilities.

It is fantastic that our plant in Svenljunga can produce renewable electricity, which can then be consumed locally, says Nicklas Eld, regional manager at Solör Bioenergi Väst. This is just the beginning. In the future we will see ORC turbines on several more of our heating plants.

Solör Bioenergi are present in over 137 locations, primarily in Sweden and Norway, and is a leading company within renewable energy from biomass. Together with the Swedish company Againity, Solör Bioenergi decided in the spring of 2018 to upgrade Hörby’s heating plant to a cogeneration plant to both reduce their energy costs and contribute to more renewable and weather-independent electricity production in a region suffering from a growing lack of local and reliable baseload power. After a year of electricity production in Hörby, Solör Bioenergi now chooses to continue installing ORC turbines. A steam boiler in Svenljunga and a hot water boiler in Vilhelmina are the coming year being provided with ORC turbines with an installed power of 315 kW and 250 kW respectively.

After these installations, Solör Bioenergi will be contributing with about 2.6 GWh of green baseload power every year from their three small-scale power plants. This corresponds to a reduction of 2360 tons of carbon dioxide emissions per year, by replacing fossil electricity from coal in the European electricity grid, equaling the emissions from a petrol-fueled passenger car driving 1500 laps around the globe.

The hot water boiler in Vilhelmina will be the first in the region of Norrland, Sweden, with a small-scale cogeneration plant, but probably not the last. Today, there are still 400 heat plants in Sweden that lack electricity generation, since previously available technology has not been cost-effective enough other than for the largest heating plants.

The heating plant in Svenljunga will be upgraded to a cogeneration plant in spring of 2020.

It feels good that the technology is being developed so that small-scale electricity generation can be applied in district heating production here in Vilhelmina, says Tore Sundqvist, Regional Manager Solör Bioenergi Nord. This means that we become more self-sufficient and our production becomes even more climate neutral, while at the same time reducing the electricity and power requirements in our local electricity networks.

With the new ORC technology from Againity, more and more Swedish cities and companies are choosing to supplement their hot water and steam boilers to reduce electricity costs and at the same take steps towards set energy and climate goals.

Eidsiva first in Norway to install ORC turbine for heating plant

During the coming winter, the Againity will deliver its first ORC turbine to Norway. It is the Norwegian energy company Eidsiva Bioenergi that has chosen to upgrade their heating plant in Elverum to a combined heat and power plant and thereby contribute to a more climate-smart and environmentally sustainable energy system.

We are honored to welcome Eidsiva as a new partner in our journey towards a more renewable and weather-independent electricity system, says Elin Ledskog, Head of Sales at Againity AB. With a first reference plant in Norway we hope to inspire more Norwegian heating companies to follow in Eidsiva’s footsteps and upgrade their heating plants to cogeneration plants.

The 0.5 MW ORC turbine converts part of the hot water from the existing boiler into electricity. The existing 10 MW hot water boiler was delivered by Jernforsen in 2016 and is fueled by recycled wood. By using parts of the renewable fuel for electricity, Eidsiva will contribute to reducing carbon dioxide emissions corresponding to over 1800 ton per year by replacing fossil electricity in the European electricity grid.

With today’s rising electricity and net tariffs, it is becoming increasingly profitable for small and medium-sized heating plants to combine their heat production with electricity generation. In Sweden, the 15th ORC turbine is now under construction and interest is growing in Norway and other parts of the Nordic and Baltic countries. With the economic and environmental benefits, the ORC turbines make an important contribution to a more renewable and weather-independent electricity system.

About the ORC technology

The turbine system is based on the Organic Rankine Cycle technology, which makes it possible to utilize low-temperature heat to generate electricity. One of the main advantages of cogeneration at biomass heating plants is that, in contrast to other renewable energy sources, it is weather-independent and generates the most electricity during winter when the demand and spot price is high. The local production of electricity also reduces transmission losses and local capacity shortages in the electricity grids.

Power plants

When generating electricity using diesel generators and gas turbines, up to 70% of energy is converted into waste heat, escaping through the exhaust gases or cooling system. By instead connecting the waste heat to Againity’s ORC system, the heat energy is converted into valuable electricity. The image below shows Againitys 400 kWe system linked to four diesel generators.

Also solar panels or geothermal heat can be used as heat sources for the ORC system. By using these energy sources to heat up water in tanks, the energy is easily stored for later usage. Whenever the need for electricity arises, the hot water is connected to the ORC system and turned into electric power.

Industrial waste heat

Many industrial processes generates excess heat that in many cases is wasted through the chimney. Manufacturing of cement, brick, glass, chemicals, tea, beer and soft drinks are examples of processes that result in large amounts of waste heat containing plenty of energy.

With Againitys ORC system, the heat is converted into electrical energy while you lower your electricity bill, bringing benefits to your wallet as well as the environment.

Produce your own green electricity! By incinerating wood chips, municipal waste, biogas or other types of biomass in a boiler and connect it to Againity’s ORC system you can become your own electricity producer. The hot water from the ORC system can be used for district heating/cooling networks or for local heat demands in industries, hospitals or hotels. See ”References” for examples of Againity’s completed ORC installations.


If you have an exisiting heating plant with a hot water or steam boiler we can upgrade your plant to a combined heat and power plant. With your own electricity production you reduce your energy bills and contribute to a greener and more weather-independent energy system.

We also offer biogas boilers together with ORC turbines for installation at landfills or waste water treatment plants.

We are Againity

We turn your waste into electric power

From waste to value

Againity utilizes low-grade heat and converts it into electricity through a so-called ORC system (Organic Rankine Cycle). Thanks to an in-house developed patented turbine, the system can utilize heat down to 90 degrees Celsius – and still have a short payback time for systems down to 50 kW of electricity produced.

The heat source

The heat source can be anything from incinerated waste, wood chips or biogas, to waste heat from a gas turbine, Diesel generator or other industrial processes. At Againity we happily help with the technical layout and financial calculations of potential projects.

Simple installation

The system is delivered pre-fabricated and installed by a simple pipe connection of the heat source and a cable to the power grid. The system is fully automated and a TCP/IP connection allows convenient monitoring and remote control. The turbine system consists of high-quality components, designed to last long periods without maintenance.

System sizes

Againity offers seven standard sizes from 20 to 2500 kW electricity, but since the systems are built as modules they can be easily combined and the maximum power output is thus unlimited. Learn more about our various models under ”Products”.

Perstorp to upgrade to combined heat and power with an ORC

In Skåne, southern Sweden, local district heating provider Perstorps Fjärrvärme AB will upgrade its 12 MW biomass-fired heat plant to become a combined heat and power (CHP) plant. This the company will achieve by installing a 250 kW Organic Rankine Cycle (ORC) unit at the heating plant.

Jointly owned by E.ON Sverige AB, a subsidiary of Germany-headed energy major E.ON AG and Perstorp’s municipality, Perstorps Fjärrvärme has chosen to invest in renewable electricity production with a so-called ORC turbine from compatriot technology provider Norrköping-based Againity AB.

In our heating plant we only burn clean biomass fuel – wood waste from the production of wood pallets and residual products from the forest. By burning a little more, we now produce our own electricity, completely green and environmentally friendly, said Charlotta Wendt, CEO of Perstorps Fjärrvärme.

Increase local installed capacity

With previous deliveries to Örkelljunga Fjärrvärmeverk and Solör Bioenergi, the order is the third ORC delivery for Againity to the Skåne region. It will be installed in the latter part of 2019.

With ever rising electricity prices and network transmission fees charges, the investment is timely. We will produce most of the electricity during the winter when it is the coldest and our own demand is the highest. We consume about 1 million kWh annually and our own electricity production will cover that need and a little more. The Swedish forest is a fantastic source of energy, remarked Charlotta Wendt.

The installation will help alleviate installed capacity shortage by increasing local installed capacity in the region. The regional electricity consumption in Skåne is today four times greater than the regional electricity production.

We are glad for the confidence shown and are happy to contribute to more local electricity production in Skåne. Perstorps Fjärrvärme is already contributing to a sustainable energy system through its renewable district heating deliveries and is now taking another important social responsibility step by supplementing with renewable electricity production, said Elin Ledskog, Sales Manager at Againity AB and supplier of the ORC turbine.

Rising interest amongst heat plant operators

The new 250 kW capacity ORC turbine is a low-temperature ORC and will be supplied pre-assembled. The installation at the heating plant consists of two pipelines from the boiler circuit, two pipelines from the district heating circuit and one electric cable. The woodchip-fired hot water boiler to which the turbine is connected has a capacity of 12 MW and was delivered by Jernforsen in 2014.

According to Againity, small-scale cogeneration with ORC turbine in the 20 to 2500 kW range is becoming increasingly common on Swedish heating plants. Innovative technology combined with rising electricity and power transmission network costs now makes it profitable for the majority of Sweden’s heating plants to be upgraded to CHP plants.

Ragn-Sells goes circular with Againity’s ORC-turbin

The waste management company Ragn-Sells is choosing to invest in new, future-proof technology from Againity AB in order to maximize electricity production. The new technology will increase the existing electrical efficiency of the existing plant.

”For us, it is about finding continuous improvements that lead us towards a more sustainable society. With this investment, we utilize the resources that already exist, stop flaring and contribute to a reduced climate impact”, says Erik Gustafsson, plant manager at Ragn-Sells Häradsudden.

The current electricity production at Ragn-Sells Häradsudden is largely driven by self-produced electricity from landfill gas and the surplus is sold to the electricity grid. Today only two out of three gas turbines are in operation and these two gas turbines are becoming worn and losing electrical efficiency.

Ragn-Sells has evaluated several different options and has now decided on a unique technical solution from the company Againity AB. The decision fell on a so-called combi installation (gas turbine and ORC turbine). With the new ORC turbine, the total electrical efficiency of the plant will increase, which means that electricity production, regardless of fluctuations in gas quantity and availability of the gas turbines, is maximized.

”In the past, considerably larger plants were required to obtain profitability in a combi-installation, making this cooperation with Ragn-Sells Häradsudden even more interesting. We will integrate existing turbines into the system in order to get as much power as possible from the gas that is taken out of the landfill, says Elin Ledskog, sales manager at Againity AB.
