For this task, a construction project was drawn up along with all the necessary documents, including a construction permit, based on two cogeneration aggregates with total heat output of 4.6 MW and electrical power of 4.6 MW. A building with specially dedicated installation was designed, taking into account the high demands associated with noise levels legally approved for buildings located in the city centre.

Specifically, the project included:

• demolition of the existing industrial building
• construction of a new building for energy purposes
• electrical installation
• gas installation
• plumbing installation
• venting system installation
• heating installation
• sanitary sewage connection installation
• transformer station installation

                                                                                                                                  Additionally, the contract included the verification of the legal status of the plots

                                                                                                                                  of land associated with the investment and the terms and conditions of connecting

                                                                                                                                  to power and gas networks.

The nominal power of the thermal network before the investment was about 50 MW (coal-based technology). The system is designed to generate warm water for general use during summer and supply the functioning of existing boilers in winter.

Within the task, complete construction and executive projects were made, based on the installation of four CHP units powered by natural gas, with total heat output of 2.6 MW and electrical power of 2.1 MW.

During the process, various documents were drawn up and obtained for the investor, including for example:

• construction development conditions
• permission for conducting archaeological research
• conditions of connecting to the existing gas network
• conditions of connecting to the existing electricity network
• construction permit
• technological projects
• CMAA (Control and Measurement Apparatus and Automation) projects
• construction project along with all the supporting documents necessary for obtaining construction permit
• industrial executive projects, with particular emphasis on the comprehensive project of receiving heat and electricity from a cogeneration unit
• technical specification of the execution and collection of works
• expertise and inventories for design and construction purposes
• geological surveys
• acoustic safety project
• works pre-measurement and investment cost estimation

A multi-sector project concerning the modernisation of the municipal heating plant in Wołomin by building a high-efficiency cogeneration system that would produce coupled electricity and heat on the basis of two systems with gas engines of about 2 MW heat output and about 2MW electrical power each, with the possibility to install additional CHP systems with the total power of about 4MW.

The subject of this project was an architectural and structural design of a thermal power plant building, a heat accumulator and ground hardening for the construction of high-efficiency CHP systems based on natural gas in the municipal heating plant in Wołomin.

The tasks included the preparation of:

• technological project
• construction projects along with all the documents required for obtaining a construction permit
• application preparation and cooperation with the investor in order to obtain the construction permit
• industrial executive projects, with particular emphasis on the comprehensive project of receiving heat and electricity from a cogeneration unit
• technical specification of the execution and collection of works
• CMAA (Control and Measurement Apparatus and Automation) projects
• expertise and inventories for design and construction purposes
• geological surveys
• acoustic safety project
• works pre-measurement and investment cost estimation
• cooperation in drawing up the SETC (Specification of Essential Terms of the Contract) for the delivery of equipment and investment implementation and participation in creating written replies to tenderers’ offers

The nominal power of the heating system before the investment was about 15 MW (gas and coal technology). The aggregate will serve as a high-efficiency cogeneration source, which, during summer, will be the main heat source for supplying the heating grid with warm water. During winter, the aggregate will cooperate serially with the two existing gas cauldrons (which constitute the main heat supply during the heating season), regardless of the required heat system parameters.

Within the task, complete construction and executive projects were made, based on the installation of a CHP unit powered by natural gas, with total heat output of 2.6 MW and electrical power of 2.7 MW.

The tasks included:

• an audit of the production part of the heating plant
• an audit of the distribution part of the heating plant
• an audit of other parts of the technological chains
• environmental impact assessment (emissions, waste management, wastewater management)
• the analysis of the issued environmental decisions and permissions
• the analysis of the procedures used for environmental protection
• technology assessment in terms of BAT requirements

The nominal power of the heating system before the investment was about 67 MW (coal-based technology).

A two-variant proposal was made for the CHP system with a total heat output of about 10 MW.

The proposal included:

• the technical and economical analysis of the profitability of the investment
• the environmental analysis during exploitation
