Background

The district heating plant in Åmål, owned by Nordic Bioenergy (formerly Statkraft Värme AB), has developed and rebuilt its district heating facility. Since 2021, its production mix has been 100% renewable. In connection with the construction and installation of a new 10 MW wood chip-fired hot water boiler, the plant chose to equip the facility with an ORC turbine to cover its own electricity consumption.

Our solution

Againity delivered an automated ORC system with a maximum capacity of 400 kW of electricity production. The ORC system enables electricity generation from the hot water produced by the boiler. In total, the system is expected to produce 1,266 MWh annually, corresponding to emission savings of 1,139 tonnes of CO₂ equivalents when replacing European marginal electricity.

Background

The district heating plant in Sölvesborg, owned by Sölvesborgs Energi och Vatten (SEVAB), is largely based on waste heat from the Sylvamo (formerly Stora Enso) paper mill outside Bromölla. In connection with an investment in a new 6 MW boiler plant from AKJ Energiteknik AB, the plant chose to equip the facility with an ORC turbine. The investment not only reduces electricity and grid costs but also helps the operation become more climate-neutral and increases baseload power in electricity price area 4.

Our solution

Againity delivered a containerized and automated ORC system with a maximum capacity of 400 kW of electricity production. The ORC system enables electricity generation from the hot water produced by the boiler.

We would like to extend our sincere thanks to Baltur Sib, Alin Vaida and Florin Cazacu for their trust and collaboration in their continued investment in renewable energy production, including a boiler from UNICONFORT.

We now look forward to delivery and installation – and to contributing together to increased production of sustainable electricity.

Today, David Frykerås and I are at Vreta Kluster taking part in the event “How to secure a resilient energy system at farm level.” We will be discussing how Againity can support farmers and others who need to secure their operations and ensure they can run fully in island mode when required.

We truly look forward to building a strong partnership and creating impact for years to come.

Background

The district heating plant in Kozienice, owned by Kozienicka Gospodarka Komunalna Sp. z o.o., has chosen to modernize its operations and work towards fossil-free energy production. As part of this initiative, the company invested in two ORC turbines that utilize hot water from two 4 MW biomass-fired boilers. This investment not only enables electricity production at the plant but also contributes to reduced climate impact.

Our solution

Againity delivered two automated ORC systems, each with a maximum capacity of 200 kW of electricity production. The ORC systems enable electricity generation from the hot water produced by the boilers. Kozienicka Gospodarka Komunalna Sp. z o.o. has chosen to sign a service agreement with Againity to ensure a long lifespan and minimal maintenance.

Background

The district heating plant in Pakalniškės, Vilnius, owned by Idex Paneriškių IQ UAB, has in recent years focused on modernizing the facility to enable fully fossil-free district heating production. As part of this initiative, the company chose to invest in two ORC turbines connected to a hot water boiler. The investment not only reduces electricity and grid costs but also helps the operation move toward greater climate neutrality.

Background

The district heating plant in Arvidsjaur, owned by Arvidsjaur Energi AB, has in recent years undergone extensive modernization to enable more sustainable production while also strengthening resilience during power outages. To both reduce operating costs and enable island mode operation, the facility invested in an ORC turbine and a battery system from Againity, integrated with a 7 MW wood-fuel-fired hot water boiler.

Our solution

Againity delivered a Battery Energy Storage System (BESS) with a capacity of 625 kW / 1,200 kWh, integrated with an ORC turbine with a maximum capacity of 400 kW of electricity production. In total, the ORC system is expected to produce 1,408 MWh annually, corresponding to emission savings of 1,267 tonnes of CO₂ equivalents when replacing European marginal electricity.
