Water and raw materials

Environment | Water and raw materials

By producing electricity and heat, we are faced with the need to consume significant amounts of water and raw materials. As the Group, we pay attention to optimising their use in production processes by applying modern solutions.

In the production process we use mainly hard coal, gas, biomass and heating oils. The basic fuel we use is hard coal, which is supplied in significant quantities by LW Bogdanka. Biomass in the form of forest chips, energy willow chips and sunflower hull pellets is used primarily at the Białystok Combined Heat and Power Plant and at the ‘green unit’ of the Połaniec Power Plant. Production of electricity and heat obtained from gas takes place in Przedsiębiorstwo Energetyki Cieplnej Oborniki and Miejska Energetyka Cieplna Piła.

Main raw materials used by the Generation Segment in 2017:

Type of raw material Quantity
Hard coal [thousand tons] 9823.9
Biomass [thousand tonnes] 1676.3
Gas [in thousands m3] 16840.9
Heavy fuel oil [thousand tonnes] 13.8
Light heating oil [thousand tonnes] 6.1
Limestone meal [thousand tonnes] 179.7
Ammonia water [thousand tonnes] 10.1
Calcinated magnesite [thousand tonnes] 0.02
Stone salt [thousand tonnes] 0.0028

21) For some companies, the value of total water consumption does not include administrative properties, which are settled on a flat-rate basis in rent for all utilities.

22) Water taken from the Vistula river – taken back for cooling and without return for technological purposes.

23) Water consumed by Enea Ciepło Serwis is recorded in Enea Ciepło Company’s consumption. Enea Ciepło The service does not keep any records, because the fee for water is included in the lump sum for renting rooms.

24) The amount of water used applies only to hygiene and sanitary rooms and offices. The water consumption of the equipment and installations entrusted to operate and the water consumption in the adjacent rooms (control rooms, bathrooms, etc.) are recorded by Enea Połaniec S.A. as their owner.

What have we done to reduce water consumption in 2017?

  • The new Kozienice Power Plant unit uses a closed cooling water circuit and its reuse. This results in high savings in water energy production processes.
  • At the Białystok Cogeneration Power Plant, we have reduced water intake from deep wells and reduced the amount of process wastewater resulting mainly from modernisation works.
  • We have modernised part of the heating network in the Generation Segment.
  • We take care of the tightness of water systems and heating networks, as well as the high efficiency of installation equipment, and subject it to regular inspections. This allows for quick diagnosis and intervention in the event of malfunctions or other problems.
