Until now, almost half of PPA CONTROLL, as's turnover has been generated by nuclear energy activities, especially projects related to the Mochovce NPP. However, in the future, we also need to look for new areas where we can apply our experience, expertise and financial stability.
"In the long term, nuclear energy activities would not be able to meet the goals of business diversification, revenue and profit that the company's management has set. Therefore, in accordance with the approved strategy, we are also looking for space in other segments and industries," says Ing. Milan Michalík, Director of the Foreign Orders Department PPA CONTROLL, a. sOne of the areas where we see potential for our activities is the modernization and greening of heating plants and the construction of incinerators.
The end of coal in the Martin heating plant
A project in exactly this spirit is the Greening of Martinská teplárenská, as, increasing its energy efficiency and ending coal-fired operation. The implementer of this project was PPA CONTROLL, as
The heating plant in Martin has been burning coal since 1949. After the dissolution of the state-owned enterprise SSE Žilina, to which the Martin heating plant belonged, the company was transformed into the joint-stock company Martinská teplárenská, as in January 2002. However, it will no longer be possible to use coal as a source. Martinská teplárenská needed modernization, thanks to which it would be possible to completely stop burning coal and switch to a modern ecological and economical method of combined heat and power production.
It is no coincidence that this project was implemented by PPA CONTROLL. "Design, construction or operation of heating plant technologies requires an experienced company with deep knowledge in the field of balance heat and energy calculations, calculations related to heating plant technological equipment and designs of piping systems, and must also ensure coordination with implementers of construction professions, etc. In some areas, we carry out activities with our own capacities, in others we use proven companies with expertise and references for a particular area for cooperation," explains M. Michalík.
A collaboration that continues
The acquisition of the project for the modernization and greening of Martinská teplárenská, as, by PPA CONTROLL, as, was the result of our active monitoring of developments in this area in Slovakia and abroad, long-term orientation also in the field of thermal energy and rich experience in the preparation and implementation of technically and organizationally demanding projects. projects.
"We have already supplied technology and services to the heating plant in Martin in the past. In this project, it was also necessary to accept the investor's demanding financial conditions in the form of refinancing the negative cash flow," M. Michalík explains the background to obtaining the contract.
PPA CONTROLL, as, received the order in December 2018 and immediately began preparing implementation projects in cooperation with other companies.
Implementation during the corona crisis
Our experience shows that in every project, certain complications and changes must be expected, to which one must adapt flexibly. In the case of the heating plant in Martin, complications arose after the declaration of restrictions by the Central Crisis Staff of the Slovak Republic in connection with the spread of the coronavirus. Small changes were also made in the area of construction modifications at the request of the investor, it was necessary to prepare an amendment to this part of the project. However, the result is not at risk. "Thanks to our experience, know-how and good cooperation of all involved parties, the project was implemented within the specified scope and quality," confirms M. Michalík.
Ecological heat in Martin
In Martinská teplárenská, as, we installed four Bosch hot water boilers with a unit output of 14,3 MW in the renovated premises and three Martin Power cogeneration units with a unit electrical output of 9,34 MW in the newly built cogeneration hall. The total newly installed electrical output is 28 MW and the thermal output is up to 80 MW. The cogeneration units are powered by Rolls Royce engine generators from the Norwegian manufacturer Bergen Engines. They are spark-ignition engines burning natural gas with an electrical efficiency of more than 48%, which are equipped with a system for utilizing heat from the engine with maximum use of fuel energy and a system for reducing emissions to the latest emission limits. As part of the new solution, a wood chip boiler is in operation as a priority, while newly installed cogeneration units supplied by TTS Martin, sro will produce a nominal amount of heat in the form of hot water for heating and domestic hot water for the city of Martin, as well as electricity and supply it to the grid.
The Martin heating plant was able to completely stop burning coal and switch to modern ecological and economical method of combined heat and power generation. "This project indicates the direction that the Slovak and Czech heating energy sector should take. Our company is ready to implement projects for the modernization and greening of heating plants and incinerators as a subcontractor or EPC contractor, using the many years of experience and know-how that we have gained in the field of energy," concludes M. Michalík.
