Againity

Againity’s first reference in Poland!

We are thrilled to announce that we will deliver two 200 kW ORC turbines for clean electricity production at Kozienice heating plant in Poland. Special thanks to our sales partner NPS New Power Sources Sp. z o.o., this would not have been possible without your contribution. Thanks also to Energika Zbigniew Szamałek Sp. K. for a great collaboration so far. This project not only enhances energy efficiency but also contributes to a more sustainable future with climate-smart baseload power. Together we create a more sustainable European electricity system!

Study visit at Ystad Energi

Last week, the Againity team had the privilege of hosting a study visit at Ystad Energi AB’s heating plant. There were a total of 60 participants, with 40 of them on-site while the rest joined us virtually.
 
During our visit, all participants had the opportunity to gain a deeper understanding of how the ORC operates and also listen to our customers’ experience and insights on how they now are mostly self-sufficiency in fossil-free electricity.
 
Thank you to all of you who participated in the event. Together, we can make a difference in the energy transition, producing more plannable electricity!

We would like to express our gratitude to Knowledge Center on Organic Rankine Cycle technology (KCORC)and the Universidad de Sevilla for organizing this event. We are happy to be a part of the Organic Rankine Cycle community!

Flen heating plant, Sweden

Background:

The district heating production in Flen started in the early 2000s and is operated by Solör Bioenergi Fjärrvärme AB. The plant consists of two biofuel boilers where mainly sawdust, wood chips and bark from the local area are burned. Solör Bioenergi aims to take advantage of the forest’s resources and contribute to a sustainable society with reduced carbon dioxide emissions, which together with reduced energy costs has justified an investment in an ORC turbine. Solör Bioenergi has previously invested in ORC turbines for the heating plants in Hörby, Svenljunga and Vilhelmina.

Our solution:
Againity delivered an automated ORC system with a maximum capacity of 99,9 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 519 MWh electricity annually, corresponding to annual emission savings of 467 tonnes of CO2 equivalents when substituting coal-based electricity.

Gamleby heating plant, Sweden

Background:

The heating plant in Gamleby is operated by Västervik Miljö och Energi AB, which in recent years has invested in a modernization of the heating plant to enable a completely fossil-free district heating production. In connection with this, Västervik Miljö och Energi chose to invest in an ORC turbine that is installed at a new wood chips-fired 5 MW hot water boiler. The investment not only contributes to reduced electricity costs and grid fees, but will also help the business reach its goal of becoming climate neutral by 2030.

Our solution:
Againity delivered an automated ORC system with a maximum capacity of 90 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 350 MWh electricity annually, corresponding to annual emission savings of 315 tonnes of CO2 equivalents when substituting coal-based electricity. Västervik Miljö och Energi has chosen to sign a service agreement with Againity to ensure a long service life and minimal maintenance.

Gislaved heating plant, Sweden

Background:

Gislaved Energi AB operates the district heating plant in Mossarp, which consists of a wood chip-fired 5 MW hot water boiler. To reduce their internal electricity costs and at the same time take a step in a climate-smart direction, Gislaved Energi AB chose to invest in an ORC turbine that enables sustainable and local electricity production.

Our solution:
Againity delivered an automated ORC system with a maximum capacity of 200 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 770 MWh electricity annually, corresponding to annual emission savings of 690 tonnes of CO2 equivalents when substituting coal-based electricity.

Finspång heating plant, Sweden

Background:

Finspångs Tekniska Verk AB operates the heating plant in Finspång, which supplies the town with district heating. The heating plant consists of a waste incineration plant, where waste that remains after material recycling is taken care of and incinerated in a 10 MW waste-fired boiler. The business’s starting point is to use climate-friendly processes and in order to develop its work towards a sustainable energy system, Finspångs Tekniska chose to invest in an ORC turbine

Our solution:

Againity delivered an automated ORC system with a maximum capacity of 450 kW electricity production. The ORC system enables electricity production from the boiler’s hot water.

Ystad heating plant, Sweden

Background:

Ystad Energi AB owns the heating plant in Ystad, which produces 100% renewable district heating. The plant’s two main boilers have a capacity of 10 MW each and are mainly fired by chipped branches and tops that remain after logging. To become less dependent on electricity supply via the electricity grid, where capacity shortages are becoming a common problem, Ystad Energi chose to invest in three ORC turbines. The two 10 MW boilers will each be equipped with an ORC turbine and a third turbine will be connected to a 5 MW boiler.

Our solution:

Againity delivered three automated ORC systems with a maximum capacity of 750 kW electricity production. The ORC system enables electricity production from the boilers’ hot water. In total, the systems are expected to produce 3220 MWh electricity annually, corresponding to annual emission savings of 2,900 CO2 equivalents when substituting coal-based electricity. Ystad Energi has chosen to sign a service agreement with Againity to ensure a long service life and minimal maintenance.
