The Siemens Gas Turbine Technologies joint venture between Siemens AG and Russia's Power Machines has filed a lawsuit with the Moscow Arbitration Court against OJSC Technopromexport Foreign Economic Association and LLC Technopromexport Foreign Economic Association, which are part of the Rostec state corporation.

The nature of the lawsuit was not disclosed. The suit was filed on September 13.

Reports have said the Moscow Arbitration Court will hear a suit filed by Siemens AG against the Technopromexport organizations and the JV on September 18 over the delivery of turbines produced by the German company to Crimea.

Siemens has said it had not brought court action against its own JV and had only sought to join it to the case. The court refused to grant a request by Siemens for an injunction by seizing the four turbines, supplied to Crimea, and halting their installation. The power plants I Crimea are supposed to go into service in May-June 2018.

Siemens accuses Rostec of having illegally delivered to Crimea four turbines intended for power plants being built on the Taman Peninsula. In keeping with sanctions, Siemens prohibited the use of its own turbines for power generation in Crimea. In response to the delivery of the turbines, the European Union has imposed additional sanctions against three Russian companies and three individuals.
