CEZ wants more batteries, especially in the areas of conventional power plants.
Mostly about CEZ battery performance but with the following snippets that may make interesting reading for this forum:- (courtesy of https://www.hybrid.cz/cez-chce-dalsi-baterie-hlavne-v-arealech-klasickych-elektraren/)
" As the share of renewable sources in the system continues to increase, so will the importance of accumulation, and we want to be prepared for that. We monitor the development of legislation and continuously prepare other battery projects, mainly in selected areas of conventional power plants, "said Jan Kalina, Member of the Board of Directors and Director of CEZ's Renewable and Classic Energy Division.
In line with its vision, to put into operation new storage capacities with an output of 300 MW by 2030. At the same time, CEZ is developing other battery projects. In selected areas of the existing conventional power plants, where, among other things, the construction of new solar parks is planned, it is currently assessing the technical aspects and economics of battery projects.
These will be both new batteries and systems composed of previously used batteries, so-called second-life, which can be reused. Their primary use will again be for the provision of power balance services. More detailed plans will depend on the development of legislation regulating the conditions for the construction and operation of storage capacities in the Czech Republic. It is expected that from the middle of 2022 the Czech Republic will join the pan-European platforms for the purchase of regulatory energy.
There are currently about 500 large battery storages in Europe, about 50% are located in the British Isles and Germany is the leader in the EU with a capacity of over 7.5 GW of storages. The global performance of the world's battery energy storage is estimated to increase more than 100-fold by 2040. In 2018, storage at 9 GW / 17 GWh was installed, while in 2040 it will be 1,095 GW / 2,850 GWh. The performance of large battery storage facilities in the USA will reach 12 GW in 2023, which will be about ten times higher than in 2019. The average efficiency of battery systems in the USA (82%) is higher than at pumped storage plants (79%) and only in California should 2.5 GW storage facilities will be put into operation this year.
