The conversion, which commenced in April 2015, is part of an agreement signed between the Vestegnens Kraftvarmeselskab (VEKS) and Dong Energy to provide green district heating to VEKS' customers in the Greater Copenhagen area.

VEKS chairman Steen Christiansen said: "Choosing the right levers to curb the ongoing CO2 emissions and thereby global warming is a complex task.

“However, using biomass at Avedøre Power Station's two units is a huge step towards achieving VEKS' goal of supplying fossil fuel-free district heating in 2025. We’ve made a difference.”

The completion conversion work marks a major step towards achieving Copenhagen's aim of being CO2-neutral by 2025, Dong Energy said.

The power plant is expected to generate district heating based on biomass for about 215,000 homes in Copenhagen.

It will also produce electricity corresponding to the annual consumption of more than 600,000 Danish households annually.

Dong Energy executive vice-president Thomas Dalsgaard said: "Following the conversion of unit 1 at Avedøre Power Station, we can produce heat for more than 215,000 Danish households in the Greater Copenhagen area without using coal or gas.

“The conversion is a major contribution to achieving a green district heating system in the Greater Copenhagen area as well as a green electricity system, supplementing solar and wind power.”

The Avedøre Power Station is also expected to reduce CO2 emissions by about 500,000t annually.
