HPP Brežice testing underway with the reservoir filled to nominal height

With work on HPP Brežice completed, generating units and equipment are now being tested and the surrounding area is getting its final touches.

All three generating units have been provisionally accepted with the reservoir filled to the low-level mark and are now in operation. After the reservoir was filled to its nominal height – 153 metres above sea level – on 11 August 2017, start-up testing of the generating units began based on their design parameters and projected rated capacity. The testing of all three generating units is expected to finish in the first half of September 2017, which will be followed by their final acceptance.

We have notified the local population and other stakeholders that during the testing stage the water level downstream from the HPP structure might increase or decrease by 0.5 m/h to a maximum of 1 m/h and that the level of water in the reservoir would change as well. The water levels of the Sava River and the reservoir are also projected to vary during the power plant's regular operation, which is to follow the testing stage – all in accordance with the Concession Agreement for harnessing the energy potential of the lower Sava River.

All locals and other stakeholders have again been warned to be extra cautious and careful in their activities near the river on account of the changing water levels of the Sava River and the reservoir.

During this time, the bridge leading to HPP Brežice over the Struga stream has also been finalized and set for a technical inspection.

The technical inspection and start of trial operation of HPP Brežice is scheduled for the end of September 2017.
