Perstorp heating plant

Background:

Perstorp Fjärrvärme AB was founded in 1980 and is today jointly owned by Perstorp Municipality and E.ON. The heating plant has a 12 MW hot water boiler from Jernforsen where wood waste from the production of pallets and residual products from the forest is used as fuel. To increase local electricity production in an area that today suffers from a lack of power, Perstorp Fjärrvärme AB chose to collaborate with Againity and invest in an ORC turbine.

Our solution:

Againity delivered an automated ORC system with a maximum capacity of 315 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 1.35 GWh of electricity annually, corresponding to annual emission savings of 1,215 CO2 equivalents when substituting coal-based electricity. Perstorp Fjärrvärme AB has chosen to sign a service agreement with Againity to ensure a long service life and minimal maintenance.
