On 24th November 2020 the first local training within the international project ENTRAIN: Enhancing renewable heat planning for improving the air quality of communities took place. The aim of the training was to familiarize participants with the heating sector in Poland, its possibilities of cooperation with RES and to present existing good examples of objects that use local renewable energy sources for heat production.

The event started with an introduction to the ENTRAIN project itself by Ms. Anna Lachowicz - project manager in the Association of Municipalities Polish Network "Energie Cités".  The main objective of the project, its stages, planned activities and expected results were discussed. This training is the first in a series of trainings for representatives of municipalities and other entities dealing with district heating, which are to ensure knowledge transfer in the above mentioned area.

Mr. Andrzej Rubczyński, the representative of the Forum Energii, presented the possibilities of using RES in the heating industry - the current state, potential, technologies. After discussing the current state of this sector and the fuel mix in Poland, he moved on to the future of this industry and the challenges that it will have to face in the coming years. Observing the growing prices of charges for CO2 emission, more and more restrictive emission limits, as well as the poorer quality and harder accessible coal - it is certain that the future of the heating industry is connected with RES. However, in order to produce systemic heat from as many renewable energy sources as possible, it is necessary to change the temperature of the medium circulating in the system. The speaker has also presented modern technologies supporting the development of RES in this field.

After the presentation of the representative of the Forum Energii, it was time for Mrs. Patrycja Płonka - the project manager in the Association of Municipalities Polish Network "Energie Cités", whose theme was how to plan the development of heating systems using RES step by step. The investment process related to the installation of the heating system was discussed, focusing on its three key stages, i.e.: analysis of formal and legal requirements and preliminary and detailed feasibility study of the investment. An exemplary tool that can help future investors e.g. in estimating heat demand was also presented, which is a free Hotmaps tool for mapping and planning energy systems for heating and cooling services.

The next point of the training was a speech by Mr. Jarosław Osiak from the University of Ecology and Management in Warsaw, devoted to estimating the local demand for district heating and local RES potential. He briefly presented the role of the municipality in the implementation of this process and factors influencing its size. Then he presented very detailed technical potential of biomass - straw, long-term plantations, forests and waste wood from orchards and roads. After presenting to the audience the possibilities of using biomass in heating, he also summarized the factors that should influence on the choice of an appropriate biomass supplier system.

After a short break, the participants had the opportunity to familiarize with the activities of Germany in the field of solar district heating system. This topic was presented by Mr. Patrick Geiger from the research institute Solites, who is one of the partners involved in the ENTRAIN project. He also talked more about the Solar District Heating, which is the website of projects aimed at supporting the development of solar thermal systems in Europe.

The last point of the training was a presentation by Mr. Dariusz Marczewski - director of the Heat Energy Company in Płońsk. He presented a good practice which is a biomass-fired CHP plant in Plonsk. The participants had a chance to learn about the history of the object, the course of changes and carried out modernizations, as well as the sources of financing of the undertaken activities. The presentation also allowed to see how much has already been achieved thanks to the taken steps, what effects of emission reduction have been achieved, as well as what are the plans of the power plant for the future, i.e. joining more customers to the heating network and building a photovoltaic power plant. Płońsk can definitely be considered as a good example of district heating in Poland, which can be followed by municipalities from the whole country.

We would like to thank to all speakers for their interesting speeches and shared knowledge, and the participants for their time. We hope that the training will bring a lot of inspiration and will result in positive changes in the Polish heating industry.
