Between 1994 and 2005 Poland was exporting between 15-20 million tons per year, often generating loss. Polish coal producers were following a strategy (dictated by social and political pressure) in which they were willing to sell coal abroad on prices lower than they could get on the domestic market just to secure stable level of production in case of decreased demand for coal in Poland (maintain fixed employment).
Decrease in export between 2000 and 2010 was partially a result of falling volume of production (from 85 million tons in 2000 to 65 million in 2010). In 2007 Polish mines had major problems with maintaining production at a sufficient level and supply domestic energy producers, which resulted in a huge fall in export that has never been brought back to the point from previous years. Figure bellow shows how the import to export relation was changing over the decade after Poland joined the EU (million tons).
In 2010, half of whole Polish coal export was supplying German consumers. Other major deliveries were directed to Czech Republic (8%), France (7%), United Kingdom (7%) and Denmark (5%).
