On a visit to Germany, Prime Minister Petr Nečas said on Friday that the Czech Republic did not intend to build transformers in order to block electricity overflows from Germany. The Czech grid is occasionally overloaded by these flows in particular when the output of wind farms in northern Germany is high. In such cases, there is a danger of a blackout for the Czech grid. Prime Minister Necas said Prague has decided to take measures in favour of strengthening the country’s own transmission networks. At the same time, he said the Czech Republic expected Germany to move to solve the problem on its own territory.
