After ascertained increasing of inflows to Kardzhali Reservoir, Studen Kladenets Reservoir and Ivailovgrad Reservoir and calculated inflows to Studen Kladenets Reservoir in the amount of 827 m3/sec, actions were undertaken with regard to a high wave passing. In order to ensure the necessary volume in the reservoirs for the expected increased inflows, such inflows are processed by the three hydro power plants owned by  Natsionalna Elektricheska Kompania EAD. Currently, the spillways of the three dams are in good condition and are in normal operation.  

The relatively low volumes of the high wave already passed, as well as the timely reaction of the National Electric Company to start intensive processing of water quantities from the reservoirs, even before the event, allowed keeping the high water wave in the reservoirs of Cascade. In this way, the overflow of water quantities through the spillway of the last step of the Cascade - Ivaylovgrad Dam, was prevented. This has been followed by water quantities processing in accordance with a schedule until the limit water levels for the Cascade set by the Ministry of Environment and Water are reached.


In pursuance of Art. 36a of the Energy Act, NEK EAD is obliged to announce its intention to change the prices it applies when performing its licensed activities for the next price regulatory period, starting from 01.07.2020.
