Development Minister Jaroslaw Gowin said Poland wouldn't shut the lignite mine in Turow, on the border with Germany and the Czech Republic, but instead was engaged in “very intensive diplomatic and law-related efforts,” to secure undisturbed operation of the mine and connected power plant that generates some 7% of Poland's energy. 

The EU's Court of Justice on Friday ordered Poland to immediately stop operation of the mine, heeding Prague's complaints that it drained groundwater from Czech territory and that Poland recently extended its license without proper prior environmental assessment. It's a temporary measure, pending the court's full ruling. 

Gowin said he considers the court's decision “scandalously incommensurate” to the situation and one that would lead to the “loss of tens of thousands of jobs and very serious disturbances in Poland's energy system,” cutting power to millions of households. 

Prime Minister Mateusz Morawiecki was holding an emergency meeting with the managers of state energy company PGE, which runs the mine and the plant, and regional authorities in Wroclaw, in the southwest. 

He later said Poland will engage in negotiations with Prague and will also make new points before the EU court to clearly describe the situation to avoid a “disaster.” 

The court's decision is “very dangerous from the point of view of potential threats to the ecology, but it is also dangerous for Poland's energy security and for the employment of some 5,000 people” working at Turow. 

He noted that both the Czech Republic and Germany are operating lignite mines and power plants close to Poland's borders. 

In an effort to follow the EU''s ambitious carbon dioxide reduction goals, Poland is gradually phasing out black coal, but still relies on lignite. A recent energy plan says the last coal mine will be shut by 2049, but critics say it will happen sooner, because Poland's coal mining is inefficient and generates enormous costs. 

Government authorities say they have been in talks with Prague over the Turow mine for years and believed an understanding had been reached. Critics and the opposition say it hasn't done enough, but all in Poland agree that closing the mine and the power plant is not possible. 

An outage last week at another PGE lignite power plant, in Belchatow, was felt across the European energy grid and made operators scramble to make up for the lost power. 

The head of Poland's PSE power grid, Eryk Klossowski, told a meeting of the parliamentary energy security group that it wouldn't be acceptable for the grid to lose Turow's input. He said the plant is connected to a power transmission station that is key for the southwestern region and for interconnection with east Germany. 

PGE deputy head, Pawel Sliwa, told an emergency meeting of a parliamentary commission that closing the mine would also entail closing the power plant that it supplies. He estimated the costs at around 13.5 billion zlotys ($3.6 billion or 3 billion euros), the layoff of thousands of employees and lost investment into filters and other pro-environment modernization. 

Coal makes up 65% of Poland's energy sources, including 17% from lignite, while about 25% of the country's energy comes from renewable sources. Poland's heavy reliance on coal is a source of tension in the 27-nation EU, which is seeking to meet ambitious goals to reduce the bloc's greenhouse gas emissions.
