Adaptation to climate change: Support to energy transition

The challenge

In Poland, where coal still accounts for almost 90% of energy resources, it is essential to develop cleaner production units in order to reduce greenhouse gas emissions - and so meet the government objective of producing 15% green energy by 2020 and 21% by 2030.


Customer objectives

The cities of Poznań and Łódź have opted to prioritize their urban heating networks over individual boilers. However, the heat and electricity production plants, some of which are more than a century old, still run massively on coal and fall far short of meeting national emissions standards and local sustainable development strategies.


Veolia’s solution

Modernize the cogeneration plants in both cities and convert them to biomass in order to reduce the level of nitrogen oxide emissions, thereby contributing to the deployment of heating networks, which are key in creating a circular economy.



In Łódź, Smart Heat, a smart heating network developed with the support of the National Fund for Environmental Protection and Water Management, has been developed. It includes telemetric management and simulation tools to optimize the use of networks and enable Veolia teams to react more quickly to incidents.

492 000 MWh

of green electricity produced/year

634,000 metric tons

of biomass burned/year

587,000 metric tons

of CO2 emissions avoided in the two cities


The Łódź and Poznań plants have been equipped with a catalytic system that keeps nitrogen oxide emissions under 150 mg/Nm3, a threshold that is well below the recommended limit of 200 mg/Nm3 (European directive in 2015).

Customer benefits

Environmental performance

  • Veolia rolls out modern solutions that reduce both pollutant emissions (coal combustion residue capture systems) and the consumption of raw materials and energy (by using biomass).
  • In Poznań, Veolia is involved in city centre rehabilitation programs by connecting buildings to the heating network, thus eliminating individual coal stoves, which not only emit pollutants and CO2 but are also a fire hazard.
  • In terms of energy efficiency, the 3 units in Łódź are among the best in the world - heat losses are less than 10% - with results comparable to those in Scandinavia.


Economic performance

By opting for an improved approach to the energy mix that incorporates biomass, Veolia is contributing to local economic development, ensuring both a high level of resource quality and availability and an economically profitable heating method (a 15 to 20% saving on consumers' bills).


Social performance

In the context of vocational training, Veolia has created special classes for the job of energy technician.


Societale performance

  • Veolia organizes educational initiatives relating to heat production and supply, including open days at cogeneration plants, and campaigns to encourage environmentally friendly behaviour day-to-day: waste sorting, efficient use of energy and water, etc.
  • Veolia works closely with local communities to improve the state of the environment and living conditions in cities, and with universities by contributing to the development of educational programs that reflect the main trends in energy development.

A national campaign with the slogan "Healthier through the heating network" was aired on Radio Three in autumn 2019. The advertising spots suggest simple ways of saving energy and resources. They remind people that by using the heating network, we safeguard health, and at the same limit the emission of toxic substances into the air. Veolia's subsidiaries in Warsaw, Łódź and Poznań continued the campaign on local radio stations from 18 November.

 In Łódź, the first thermoelectric power station, built in 1907, has become a contemporary cultural centre. Inside, Poland's most modern Planetarium serves as an open space for workshops, art exhibitions and other events. A Science and Technology Centre also offers exhibition spaces including the former engine room, boiler room, pump room, cold storage and switchgear room


Veolia Energia Łódź, heir to the traditional energy suppliers in Łódź, is an important partner of the Łódź branch of the Association of Polish Electrical Engineers (SEP), which celebrated its 100th anniversary in 2019. As part of the Jubilee, Veolia Energia Łódź was honoured by SEP for its contribution to the development of Polish energy engineering.
The SEP branch in Łódź and Veolia Energia Łódź jointly implement numerous science, education and history research projects that benefit not only the energy sector but also people living in both the city and the region.
