Kazanorgsintez filed a claim with the Arbitration Court of Tatarstan for recovery of ₽9.5 billion advance payment from Siemens for the construction of a 250 MW combined-cycle plant for the needs of the chemical plant. The CCPP was supposed to be commissioned on a turnkey basis by March 2023, but in July 2022 Siemens notified that it was refusing to fulfill its obligations due to the EU sanctions, after which all work at the site was stopped.
