DONG Energy Herning biomass CHP plant scores deal, plans upgrade

By Anna Simet | May 01, 2017

After two years of negotiations, DONG Energy has reached a deal to continue delivering district heating to three Danish energy companies via its Herning, Central Jutland, Denmark, biomass-fired combined-heat-and-power plant.

According to the deal, Herning Power Station will supply Eniig Varme, Energi Ikast Varme and Sunds Vand- og Varmeværk with district heat until 2033, an agreement entailing construction of a flue gas condensation plant that will increase the plant’s efficiency. According to DONG Energy, construction of a facility, which will utilize recovered heat, will allow the power station to deliver the same amount of heat, but consume 20 percent less fuel than it currently uses.

Herning Power Station was commissioned in 1982 and originally designed for coal and oil, but has undergone three conversions since 2000. Today, the plant runs on wood chips—about 280,000 tons per year—and 70,000 to 80,000 tons of wood pellets, capable of producing 80 MW of power and 174 megajoules of heat.

"I'm pleased that Herning Power Station will continue to provide stable, green district heating to our heat customers in Herning, Ikast and Sunds,” said Thomas Dalsgaard, executive vice president of DONG Energy. “With the new agreement, we're making Herning Power Station even more efficient and consequently more climate-friendly.”

 "In Ikast, we're satisfied with the results of the very lengthy negotiations as the agreement ensures continued green heat supply for our district heating customers, which means that we can maintain an attractive heat price for our part owners in Ikast," said Kaj Hansen, CEO of Energi Ikast.

The new heat agreement covers the period 2019-’33, and DONG Energy expects to begin building the new flue gas condensation plant during Q4 2017.
