The Tušimice battery tested well
A sudden drop in power frequency in the grid requires back-up sources capable of restoring the balance within 30 seconds. In their BAART project, ČEZ and ČEPS tested the connection of a high-capacity battery system for providing power balance services, in particular automatic frequency regulation. The first 16 scenarios tested simulated actual operational situations and conditions, including up to 37 activations of automatic charging/draining of the battery store per week – that is the balance of the battery located at the Tušimice Power Plant grounds. During the one-year test, its reliability and ability to quickly respond to frequency deviations was proven.

ČEZ power plants saved 67 million cubic meters of surface water last year, reducing the usage of the valuable liquid by more than 14% y/y
In recent years, ČEZ has repeatedly achieved major savings of the valuable liquid. Last year, it reduced its consumption of surface water in its nuclear power plants by nearly 7% and in its traditional power plants by 16.5%.

Due to one-off measures, CEZ Group’s earnings in 2020 were CZK 9 billion less than in 2019. Despite covid-19, its EBITDA rose by CZK 5 billion to nearly CZK 65 billion.
CEZ Group’s EBITDA for 2020 reached CZK 64.8 billion, up by 8% year-on-year. The growth can be attributed primarily to rising selling prices of electricity due to the multiple-year pre-sale in the wholesale market and also due to the stable operation of nuclear sources. The negative effect of covid-19 to the tune of CZK 3 billion was fully compensated mostly by higher profits from commodity trading and lower costs compared to the original expectations. Net Income after non-monetary adjustments grew by 21% year-on-year and reached CZK 22.8 billion. Net Income decreased to CZK 5.5 billion due to increased creation of adjustments related to the sale of Romanian assets and deteriorated conditions for the coal-based energy as well as due to record growth of emission allowance prices.

Power engineers use smart solutions to retain water in the region
The new infiltration basins at the Dukovany Nuclear Power Plant should contribute to the restoration of the ground water level in the locale in upcoming years. The power plant has completed its first, near the new parking lot. Another infiltration basin will be created during the construction of a new administrative building. In addition to retaining water in the countryside, power engineers also focus on cost savings, in particular in the form of treatment and new technologies.
