Description
The main goal of the project is to increase the energy efficiency of the central heating system.
Detailed goals include:
-the additional ability to generate heat and electricity in high-efficiency cogeneration,
-reduction of CO2 emissions,
- primary energy savings,
- elimination of the local heat source.
The project involves replacing a coal-fired boiler with a gas cogeneration installation with accompanying
infrastructure, including an energy storage, installation of cold production from heat as well as construction of
new sections of the heating network and heat network modernization to avoid heat looses.
The heat production from the newly built installation is 189 319,10 GJ/year (including useful heat 187 464,38
GJ = 52 073,44 MWh) and electricity production is 32 500,14 MWh/year.

Summary of project results
The project was to solve the problems related to increasing energy efficiency in the company and in the country, as well as to reduce high emissions to the environment . The main goal of the project was to increase the energy efficiency of the central heating system. Detailed goals included:
-the additional ability to generate heat and electricity in high-efficiency cogeneration,
-reduction of CO2 emissions,
- primary energy savings,
- elimination of the local heat source.
Pre-project situation: In Poland, conventional sources (coal) are used to produce heat, which are characterised by high CO2 emissions. District heating consumes approx. 24 million t/y of coal (38% of extraction), and 80% of the systems is inefficient. There is a clear problem of rational use of resources and the lack of efficient manufacturing systems.
The main problem of the Beneficiary is high emissions to the environment and too low energy efficiency. It will be possible to solve the problem by implementing the project in a specific scope. The liquidation of
the local coal heat source and the replacement of the current production of heat from a coal source with heat obtained from gas in the high-efficiency cogeneration technology will contribute to the achievement of the goals. The selection of the project scope was preceded by an extensive analysis of options. The Beneficiary considered various technologies of high-efficiency cogeneration and chose the option that best met the economic and ecological conditions.
The project in question consisted in the modernization of the heating system in Siedlce through the implementation of activities to increase the share of high-efficiency cogeneration in the generation of system heat. The project was aimed at increasing the energy efficiency of the district heating system in Siedlce.
The project included the following tasks:
1. Construction of a gas-fired cogeneration unit with a capacity of approximately 8 MWe.
4. Construction of new sections of the heating network.
5. Modernization of the water heating network in the Młynarska housing estate.
6. Information and promotion.
7.Information campaign.
8. Modernization of the steam turbine controller of the EC2 gas-steam unit.
The economic situation at that time (pandemic, high inflation, increase in the prices of construction materials and others) influenced the decision to abandon the implementation of tasks 2 (Construction of a cold from heat generation installation) and 3 (Construction of an energy storage facility).
The project ensured the production of heat and electricity from gas in high-efficiency cogeneration technology, replacing the existing coal source. The project enabled the liquidation of the WR-25 coal heat source. As part of the project, the construction of new sections of the heating network was carried out, as well as the modernization of the existing sections of the heating network, to reduce transmission losses, and thus reduce CO2 emissions into the atmosphere and increase energy efficiency.
The planned heat production will amount to approximately 178 916 GJ/year. Electricity production will amount to not less as 32,500.14 MWh/year.
The investment is located in the city of Siedlce in the Mazowieckie Voivodeship, mostly on the premises of the Przedsiębiorstwo Energetyczne w Siedlcach Sp. z o.o., at 7 Starzyńskiego Street.
