Revitalization and modernization of TPP Bitola

The project includes the following three stages:

• Revitalization and modernization of turbines and generators and automation at TPP Bitola – completed in full in 2012
• Revitalization and modernization of the boilers and reduction of NOx at TPP Bitola and modernization of the cooling towers
• Revitalization and modernization of TPP Bitola, accompanied by reduction of SOx and dust
  • Revitalization and modernization of the boilers and reduction of NOx at TPP Bitola and modernization of the cooling towers

An agreement was signed with Babcock Borsig for the modernization of the boilers and reduction of NOx as part of the project entitled “Revitalization and modernization of TPP Bitola and reduction of NOx”. The project is expected to:

• Extend the life of the boilers for at least another 120,000 hours;
• Increase the efficiency of the boilers, and
• Reduce the emissions of NOx

The plan was to revitalize and modernize TPP Bitola and reduce the NOx at blocks 1, 2, and 3 within the period between 2012 and 2014. The boiler at block 3 was successfully revitalized and modernized in the period August-November 2012. The works on the boiler at block 2 were completed in July-October 2015, and the activities at block 1 will be carried out in 2015.

Central heating of Bitola, Novaci and Mogila – stage one

• Ekonerg, Croatia developed the feasibility study.
• On 08.05.2013, a working group consisted of members of TPP Bitola was set up to work on the section of the hot water supply station at PE Thermal power plants of the subsidiary REK Bitola, with the task of implementing all required activities related to the design and construction of the hot water supply station at the PE Thermal power plants of the subsidiary REK Bitola.
• As part of the preparation, i.e. adaptation of the production facilities in the thermal power plant for recovering steam for the needs of the hot water supply station, an agreement was entered into with Silovie Mashini (the producer of the existing equipment) for reconstruction of the turbines, worth 246,154,000 denars. The reconstruction of the turbine blocks 2 and 3 for the purpose of regulated recovery of steam was carried out by installing outer structures on the new steam channeling pipelines between the middle and low pressure cylinders.
• A working group was set up to implement the entire project, consisted of representatives of ELEM-Head offices, REK Bitola, and the Manager of ELEM Toplifikacija.

• The bidding procedure for development of a basic project for construction of a central heating network and an infrastructure project is completed. An agreement is signed with Energo system, DOO Skopje.

• An updated geodetic surveying map and a preliminary study for numerical data have been developed. The final study on numerical data will be developed following the adoption of the infrastructure project.
• International financial institutions / foreign commercial banks have been invited to submit bids for financing the project and the following ones expressed their interest in doing so by the end of the deadline: the European Bank for Reconstruction and Development, Deutsche Bank, and KfW Bank. The bid submitted by KfW Bank, supported by the German Government, was selected as the best one.
• At a suggestion of KfW Bank, together with the developer of the main project, the project was optimized to take into account a lower coefficient of households and companies connected: instead of 0.75 – as it was suggested in the Study – a coefficient of 0.5 was assumed, and the estimated central heating consumption in the first stage was reduced to 100 MW. An additional consumption of 100 MW is anticipated in stage two, to end up with consumption of 200 MW in the final stage.
• Materials with technical and financial parameters have been developed and submitted to KfW Bank.
• The mission of approving the finances for the project with representatives of KfW Bank has been completed.
• In accordance with the Consulting Services Agreement, meetings were held with the consultants from the Faculty of Mechanical Engineering – Skopje with regard to the optimization of the heating pipeline and the main equipment.
  
  

Modernization of TPP Oslomej

• The public procedure of selecting a consultant who would develop a feasibility study and implement the “Modernization of TPP Oslomej” project is completed and the bid submitted by AF Konsult – Switzerland was selected as the best one.
• An agreement was signed with the consultant and, following the first meeting, initial activities began to develop the feasibility study and implement the “Modernization of TPP Oslomej” project. The consulting services consist of 4 stages:
  • development of a feasibility study,
  • support during financial negotiations,
  • a stage to include procurements related to the design and construction of the facility, and
  • project implementation.
