Czech grid operator: Two units at Sev.en’s Chvaletice must remain open

The Czech electricity grid operator,?CEPS, said that on Tuesday two of the four 200-megawatt coal-fired units at Sev.en’s?Chvaletice?coal-fired plant should continue to operate in order to maintain grid stability.

Sev.en owned by billionaire Czech Investor Pavel Tykac has announced that it will close Chvaletice, along with its lignite fired plants in Pocerady, and Kladno, between the end of 2020 and the first quarter 2027.

CEPS will send its?analysis to the market operator ERU. ERU will then be responsible for securing the operations of the units required, either through an agreement with the existing?owner, or through another operator. Sev.en had no ?immediate comment.

CEPS stated that a complete shutdown of Chvaletice could, in certain operating conditions, cause problems with voltage regulation in the northern part the transmission grid. It may also increase the risk of overloading some lines.

High EU carbon allowance costs have driven lignite plants that emit carbon out of the market, even though they still produce a significant minority of Czech electricity.

However, critics of EU policy say that lignite plants continue to play an important role - especially on days when there is little wind or sun for renewable energy plants.

Grid resilience is being closely monitored in Europe, as the increasing share of solar and winds energy output creates more demands on transmission networks. Reporting by Jan Lopatka, Jason Hovet. Mark Potter edited the article.
