Description
The existing Czechnica CHP plant may operate on the basis of a district heating derogation until the end of 2022. The devices in it are worn out and will not be able to meet stricter requirements from the EU Commission Implementing Decision 2017/1442 of 31.07.2017 establishing the conclusions on the best available techniques or ensuring the continuity of heat supply for residents and institutions connected to the municipal heating network in Siechnice and Wrocław.
In order to secure the supply of heat and electricity to individual consumers, a new high-efficiency cogeneration unit fired with natural gas will be built, replacing the coal source. The new unit will include a gas and steam unit with an electric capacity of 155-180 MWe and approx. 160 MWt of heat capacity. In addition, the CHP plant will be equipped with a heat storage unit and a peak-load unit with an estimated capacity of approx. 150 MWt.
Project goals:
- new high-efficiency gas-fired cogeneration unit
- security of energy supply for individual consumers
- CO2 emission reduction: 622,005.90 t/year
- primary energy savings: 598,928.89 MWh/year
Project implementation beneficiaries: individual and institutional heat consumers in Siechnice and partly in Wrocław, as well as electricity consumers from the national electricity system will gain security of energy supply.
Summary of project results
The goal of this project is to improve the supply security of energy, addressed to the end users located within the area of Siechnice and a section of Wrocław, through construction of a new source of highly-efficient cogeneration. The coal source is going to be replaced with the source supplied with low-emission fuel and the negative impact on the natural environment shall be decreased through reduced emission of CO2 and savings of primary energy
The fundamental subject of the Project named „New Czechnica Power Plant” was construction of new gas cogeneration unit. Basic production unit is a combined cycle gas and steam plant, enabling to reach the gross power ranging from: 150 to 180 MWe of electric power and ca. 160 MWt of heat power. The plant is equipped with a peak standby boiler house having an expected power of ca. 150 MWt, generating additional heat in the peak periods as well as over planned or emergency shutdowns of the combined cycle gas and steam plant. The project provided for construction of the heat accumulator with the volume of approx. 13 000 m3, allowing for storage of excess heat generated by the combined cycle gas and steam plant in the form of hot water. Additionally, the project carried out non-investment operations, i.e. a communication and promotional campaign as well as educational actions, aimed at spreading knowledge on targets regarding EEA and Norway Funds and raising social awareness of power efficiency, using eco fuels and project’s impact upon the natural environment.
As the result of the Project, there are such indicators such as:
- building a high-efiiciency cogeneration facility (1 pc.).
- sdditional electrical capacity of electrical and thermal energy in high-efiiciency cogeneration (339 MW)
- numer of industrial process with implemented energy efficiency tools (cogeneration) (1 pc.)
- conducting an information campaign (1 pc.)
The investment is going to bring positive ecological results in terms of air protection and its main ecological effect will be a reduced emission of CO2, arising out of the building of a new source of high-efficiency cogeneration. The coal source will be replaced with a source fired with low-emissive fuel, and the negative impact on the environment will be reduced by reducing CO2 emissions and saving primary energy.
Output indicators:
- Reduced or avoided emission of CO2 – ranging at 622 005,90 tons annually,
- Primary energy saving – ranging at 598 928,89 MWh/year,
Target groups
- entire society, including individual and institutional recipients of heat in the area of Siechnice and part of Wrocław as well as electricity consumers from the National Power Grid,
- recipients of the communication and promotional campaign and educational actions.
