Sustainable management of resources

We want to minimise our use of raw materials and consumables. We implement circular economy and combine large investment projects with lesser changes in every-day operation of the organisation. We manage the raw materials and consumables in a safe and environmentally-friendly manner and ensure appropriate handling of waste and sewage. We carry out projects to improve environmental awareness of our Employees and to protect the environment. We invest in green education in the Group’s surroundings.

Water

Water is a raw material necessary to generate electricity. The Group uses it in the cooling systems in the Kozienice and Połaniec power plants.

Compared with 2021, the Enea Group’s companies’ total water withdrawal fell by over 30 percent and in 2023 was lower by over a million litres. This is the effect of the development of renewable energy sources and reduced use of conventional sources.

Water withdrawal by the Enea Group

Water withdrawal [Ml]1) 2) 3)¹⁾²⁾³⁾	2021	2022	2023
Total water withdrawal by Enea Group’s companies	3 582 082	2 942 127	2 490 594

¹⁾Real properties for which detailed data on water withdrawal is not available (e.g. because the companies settle their accounts with administrators on a lump sum basis) have not been taken into account.

²⁾99 percent of the water withdrawal by the Kozienice Power Plant and the Połaniec Power Plant is the intake/return of water from the Vistula River for cooling purposes.

³⁾A decrease in energy production from conventional sources in 2023 (by 21.5 percent compared to 2022) resulted in a decrease in water withdrawal at the Enea Group.

Circular economy initiatives

We minimise the amount of waste making the most of the resources. We use the latest technologies to further implement circular economy and thus reduce our impact on the environment. Here are some examples of our initiatives.

Enea Elektrownia Połaniec uses the combustion waste from co-firing coal and biomass and gypsum generated in the flue gas desulphurisation system as high-quality by-products which are recovered or neutralised, other than in a landfill. The company sorts other waste and passes it on to third parties for management. The company has a Programme for managing waste at the Power Plant in place. It is attached to the Environmental monitoring procedure and regulates all issues relating to waste from electricity generation and is updated if new types of waste emerge.

Enea Wytwarzanie takes action to maximise the sales of ash and gypsum which translates into the reduction of the generated waste transferred for disposal.

Enea Nowa Energia has implemented circular economy practices in its biogas plants – it uses the waste from a different industry to minimise the amount of waste it generates. The company uses agricultural waste to generate biogas and the digestate generated in the production passes on as fertiliser to be used in agriculture.

Enea Operator repairs and renovates transformers, meters and concrete poles. This way it extends the lifecycle of materials and reduces the amount of waste.

Enea Logistyka passes on used sources of light and fuses to an authorised recycling entity.
