The study analyzes the development of the stationary battery market (BESS) and its impact on the flexibility market in the Czech Republic. It examines the volume of BESS that will be installed in the Czech Republic over the next ten years and for what services, the main factors influencing expansion, and the impact of connecting power balance services markets. Furthermore, the study analyzes the future and competitiveness of current flexibility resources and the potential for aggregating small sources.
⚪︎ BESS prices are falling on the market, but revenues from flexibility are falling even faster. The current price decline is a result of China’s current overproduction. The pace of price decline is likely to slow down.
⚪︎ The final price of BESS delivery is increased by cybersecurity requirements, system software integration, and guarantees required from suppliers.
⚪︎ If BESS prices fall as projected, BESS will be able to offer technical and commercial flexibility at a competitive price.
⚪︎ We expect the ratio of installed BESS capacity to iRES in the grid to reach 30% in the Czech Republic by 2035.
⚪︎ Battery duration (i.e., the ratio of BESS capacity to BESS power) will increase from 2 hours to 4 hours. Capacity will also be retrofitted to already installed BESS.
