Olofströms Kraft AB

Background

The district heating plant in Olofström, owned by Olofström Kraft AB, has in recent years focused on environmentally friendly and locally produced heat. As part of this initiative, Olofström Kraft chose to invest in an ORC turbine powered by a 9.5 MW boiler fueled with wood chips and pellets. This enables the plant to reduce operating costs while increasing the share of renewable electricity production.

Our solution

Againity delivered an ORC system with a maximum capacity of 200 kW of electricity production. The ORC system enables electricity generation from the customer’s existing hot water boiler and is expected to produce 641 MWh annually. This corresponds to emission savings of 572 tonnes of CO₂ equivalents when replacing European marginal electricity.
