Project Status: FGD Plant at the “Nikola Tesla A” thermal power plant in Obrenovac, Serbia


➡️ Installation of FRP pipelines and recirculation system pump house is progressing well.

➡️ Rubber lining of tanks and the flue gas ducts on C1 are going well, all seventeen segments of the wet stack on the absorber C1 were successfully installed.

Since 2019, Activ has been working on this large and important project together with Mitsubishi Power, Japan.

This project represents a significant environmental contribution to Serbia thanks to the FGD system, emissions of sulphur dioxide and particles will be reduced 9️⃣-times in the future, from about 74,000 tons to 7,800 tons per year.

Kelag Renewable Energy Conference “The road is long, the time is short”


Our partner KELAG-Kärntner Elektrizitäts-Aktiengesellschaft organized The Renewable Energy Conference. 🌱☀️🔋

The topic was “The road is long, the time is short,” with a focus on the energy transition in times of crisis.  

🟢 Top-class speakers in business, science, and politics dealt with questions such as renewable energy sources, energy turnaround, and climate protection from different perspectives, including political, technical, and economic points of view.

🟢 Speakers largely agreed that these issues, especially in light of the current conflicts, are a challenging task that concerns everyone, not only politicians and energy suppliers.

ACTIV attends their conference every year as a representative of Kelag in the Western Balkans, mainly because the best speakers always discuss current and future challenges in energy supply.

Project Status: FGD Plant at the “Nikola Tesla B” thermal power plant in Obrenovac, Serbia


☑️ We have verified the project implementation alongside our partner Mitsubishi Power from Japan, a company that will provide state-of-the-art flue gas desulphurisation technology on this project.

The TENT B flue gas desulphurisation project will reduce sulphur dioxide emissions from 80,000 tons per year, to 4,500 tons, which is about 20 times less.

Therefore, the construction of the FGD plant will not only extend the lifetime of the TENT B unit, but also reduce the level of air pollution while improving energy efficiency in the country.

☑️ The project is progressing very well thanks to the efforts, expertise and experience of all the partners involved.

ACTIV’s third ground-breaking ceremony for FGD projects

On 01 December 2020 in Obrenovac, the ground-breaking ceremony took place for one of the most important ecological projects of the flue gas desulphurisation plants (FGD) – for the thermal power plant Nikola Tesla B Obrenovac (TENT B).

Shinichiro Mitsuyama, the managing director of the Mitsubishi Power Branch office in Belgrade, expressed satisfaction that Mitsubishi Power is engaged in the construction of the FGD plant, which will contribute to the improvement of environmental protection thanks to the best Japanese technology. He further pointed out that the company would build a reliable plant in a timely manner, which would be a true display of friendship and cooperation between Serbia and Japan.

The deadline for the completion of the project and the takeover of the plant by the state-owned electric utility power company EPS is scheduled for March 2024. With the construction of the FGD plant for both units of thermal power plant Nikola Tesla B, it is expected to reduce the total amount of sulfur dioxide emissions from 3000 mg/Nm3 and reduce them to the level of 130 mg/Nm3.

Trial operation of FGD plant at TPP Ugljevik continued

The company Mitsubishi Hitachi Power Systems (MHPS) withdrew its experts due to the COVID-19 epidemic in April 2020, which partially stopped the trial work. At the end of July 2020, the plant was put into operation again, and the TPP Ugljevik reduced the level of air pollution significantly below the prescribed environmental standards. As of 26 July 2020, the flue gas desulphurisation (FGD) plant in the TPP Ugljevik is back in operation. According to Milutin Tasovac (executive director of TPP Ugljevik), it is showing excellent results, and the trial work will last another 15 days.

Serbian desulphurisation project will be completed by May 2023

The largest environmental project in Serbia regarding the construction of the flue gas desulphurisation (FGD) system at the TPP Nikola Tesla A in Obrenovac is progressing well. This project not only ensures clean air for Obrenovac, but also guarantees the extension of the largest EPS TPP TENT A. The contract for the FGD system in TENT A was signed in 2017 and the plant will be operational from May 2023. This will reduce SO2 emissions at units A3, A4, A5 and A6 as much as 9-fold, from about 74,000 tons to 7,747 tons per year.

ACTIV Project Management GmbH is responsible for the project management in conjunction with the cooperation partners Mitsubishi Hitachi Power Systems, Ltd. (MHPS) and its Duisburg-based subsidiary, Mitsubishi Hitachi Power Systems Europe GmbH (MHPSE).

ACTIV is able to maintain the support of MHPS on site during COVID-19

Due to the coronavirus restrictions, our partner Mitsubishi Hitachi Power Systems (MHPS) had to withdraw its experts from the construction sites Ugljevik and TENT A3-A6 Obrenovac in April 2020. ACTIV, however, was able to continue the work, despite the current restrictions, with the local teams that have been working on both construction sites since the beginning of both flue gas desulphurisation (FGD) projects. As a result, MHPS was able to continue to fulfil its contractual obligations for both projects.

For ACTIV, it is especially important in the current situation to be a reliable and stable partner for our business partners and customers. The employees of the ACTIV teams on site naturally adhere to the strict official regulations in their interpersonal dealings in order to prevent infection with coronavirus.

We would like to thank our local employees most sincerely for their work, for their dedication and commitment in the current situation!

We look forward to hearing about your project.
