MOSCOW — Russia outfoxed European Union sanctions by delivering gas turbines made by Germany's Siemens to the annexed Ukrainian region of Crimea. Now for the hard part, switching them on. No Russian company, according to Reuters data, has ever got a Siemens turbine working without the help of the manufacturer. In this case, Siemens said the turbines were shipped to Crimea behind its back and is refusing to be involved, leaving Moscow to work out how to start them up to fulfill President Vladimir Putin's promise to give Crimea a stable power supply. Siemens has filed a lawsuit against its Russian customer over the delivery of the turbines to Crimea, and says it will do everything in its power to block their installation and commissioning. If Russia can somehow get the turbines operating at the two new power plants under construction, having irked Europe by delivering them, it will again demonstrate its ability to thumb its nose at the sanctions.
