Congratulations to Veks on reaching the national target of reducing CO2 emissions by 70%, already!

Date: 08/01/2021

District heating is the key to green conversion, once again.

District heating customers in VEKS supply area have already reached the national target of reducing CO2 emissions by 70% by 2030
Reducing CO2 emissions is not new in VEKS. In fact, they have been focusing on this task since VEKS "went into operation" on October 1, 1987.

Excess heat
The first major step was to connect the local district heating companies in VEKS supply area to the transmission network. Thus, fuel oil, coal and natural gas, which had previously fuelled the local boilers, could be replaced by district heating from VEKS based on cogeneration and surplus heat from waste incineration plants. This process was completed in 1990 and is the year that has subsequently been used as a reference year to calculate the CO2 emissions that the district heating customers in VEKS supply area have given rise to.

From 1990 to 2000, the possibilities for reducing CO2 emissions were limited:

        • At the peak and reserve cargo centres, fuel oil was replaced with light gas oil or natural gas.
        • VEKS 'energy consultancy focused on lowering the return temperature in the transmission network, which reduced both heat loss and electricity consumption for pumping and ensured a better efficiency at the Avedøre Power Plant. All measures that resulted in reduced CO2 emissions.

       

      Sustainable biomass
      In 2001, Avedøre Power Plant unit 2 was commissioned. The heat production in the new unit was based on natural gas and wood pellets, which had a decisive influence on CO2 emissions in the coming years.

      With the Energy Agreement from 2012, legislation was opened up for both Ørsted and the owner of Avedøre Power Plant as well as for VEKS - to be economically attractive to convert Avedøre Power Plant unit 1 from coal to sustainable biomass. In the same year, VEKS bought the biomass-fired CHP plant in Køge, which today covers more than 10% of VEKS total heating needs.
      From 2016, Denmark's largest combined heat and power plant, Avedøre Power Plant, has produced heat on both units based 100% on sustainable biomass instead of coal and gas.

      VEKS customers have reached the goal
      With the Climate Agreement from June 2020, a large majority in the Folketing decided that Denmark in 2030 should reduce CO2 emissions by 70% compared to 1990.
      And where does VEKS stand in relation to this goal? In 1990, CO2 emissions from a district heating customer in VEKS 'supply area were 58.22 kg / GJ, while in 2019 it was reduced to 17.86 kg / GJ. This corresponds to a decrease of 70.3% since 1990! Emissions have fallen further in 2020. So by being a district heating customer in VEKS 'supply area, by the turn of the year 2020/21, they are already in line with the national targets that apply for 2030.

      "Achieving the goal of 70% CO2 reduction already in 2020 is something to be proud of - proud to be part of a community that over the past 30 years has had a sustained focus on green conversion. We are on target - and we will make it even better in the coming years. Lars Gullev, VEKS 'director. "
