Tauron announced that its recently launched 910 MW block in Jaworzno will be fueled in ca. 60% with coal from Tauron's own Sobieski mine and in ca. 20% with coal from the group's Janina mine, the Ministry of State Assets said in a response to an MP inquiry. The block will rely on "other providers" in the remaining ca. 20% in case Tauron's mining arm has supply difficulties.
