Improved version of Herning Power Station ready to supply heat and power
In snow and sleet, Kristian Jensen, the then Danish Minister of Finance, turned the first sod for the conversion of Herning Power Station on 1 March 2018. The combined heat and power (CHP) plant was to be upgraded with a flue gas condensation plant, utilising the residual heat in the flue and making the plant more efficient. The conversion has now been completed.
“With the new plant at Herning Power Station, we’ll be able to reduce our fuel consumption by around 20 per cent. That’s very good news for our climate and for our district heating customers, as our wood chip-fired CHP plant will now become even greener,” says Ole Thomsen, Head of Production in Ørsted’s bioenergy business.
The conversion project was launched at the same time as Ørsted signed a 15-year agreement with the local Danish energy companies ‘Eniig Varme’, ‘Energi Ikast Varme’ and ‘Sunds Vand og Varme’ to continue supplying district heating from Herning Power Station.
A green journey
Herning Power Station dates from 1982 and was originally a coal-fired power plant. In 2000, it was converted to using natural gas as fuel, and two years, later it was converted once again to using primarily wood chips as fuel.
Since 2009, Herning Power Station has been able to run exclusively on biomass – primarily wood chips supplemented with wood pellets. The establishment of the new plant makes it possible to use the residual heat in the flue, resulting in an even more efficient power station that can lower its fuel consumption significantly.
Ørsted’s seven largest CHP plants, of which Herning Power Station is one, cover about a quarter of Denmark’s district heating consumption. Five of the CHP plants have already replaced coal and gas with wood pellets and wood chips from sustainable production forests, and since 2006, Ørsted has reduced its coal consumption by 82 per cent. At the end of 2022, all of Ørsted’s CHP plants will have phased out coal entirely.
