The
initial release of flue gases and limestone slurry via the B1 absorber at the
desulphurisation plant in TENT B has been successfully completed. A similar
trial is scheduled for mid-August, involving the B2 absorber. Construction of
the desulphurisation system at TENT B is now in its final phase. All structural
work has been completed, and a series of operational tests on individual
components of the system is currently underway.

To date, more than €400 million has been invested in the construction of
desulphurisation plants at TENT A and TENT B, with the latter representing one
of the most significant undertakings—and the largest environmental
investment—by Elektroprivreda Srbije. A similar system was completed at TENT A
last year, and both plants are expected to make a substantial contribution not
only to environmental protection but also to the health and wellbeing of
residents in Obrenovac and the surrounding area, said Milan Aleksić, Advisor to
the Minister of Mining and Energy, during a visit to the TENT B construction
site.
He
emphasized that it is crucial for both thermal power plants—still the backbone
of Serbia’s electricity generation—to be equipped with desulphurisation
systems, as this will enable them to operate for a longer period.
The
plant at TENT A has been successfully completed and tested, and attention now
turns to the finalization of works at TENT B, which is expected to enter its
trial phase by the end of the year. Aleksić emphasized that it is therefore
vital for all parties involved in the final stage of construction to adhere to
the agreed timelines and project milestones to ensure the system begins trial
operations as planned. To safeguard energy security and enhance environmental
protection within the power sector, the Ministry of Mining and Energy remains
actively engaged in the implementation of the project at both power plants. “It
is our duty to continue supporting EPS in planning and securing the necessary
funding for environmental initiatives, particularly the deployment of primary
and secondary environmental protection measures at thermal power plants,”
Aleksić stated.

Živković, General Manager of Elektroprivreda Srbije (EPS), noted that following
the completion of desulphurisation systems on three units at TPP Kostolac B,
four units at TENT A, and both units at TENT B, all major thermal power plants
operated by EPS will be fully compliant with both European and national
environmental standards. He underscored the significance of the project,
highlighting that the new systems will enable Serbia’s large thermal units to
operate reliably over the long term, while fully adhering to environmental
protection requirements.
- A successful hot trial has been carried out,
involving the release of flue gases and limestone slurry through the B1
absorber—marking a key milestone in the overall technological process. The
appearance of white smoke from the stack serves as visible confirmation that
the system is functioning, and that the fine-tuning of operational parameters
is now underway. “We expect the desulphurisation system at TENT B to enter
trial operation by mid-December,” said Dušan Živković, General Manager of EPS.
One
notable advantage of the project is its contribution to the circular economy:
the use of limestone in the desulphurisation process results in gypsum as a
by-product, which can be repurposed for use in the construction industry.
