Siemens AG will freeze new wind power investment plans in the U.K. until it has further clarity on the U.K.’s future trade relationship with the European Union, a spokeswoman for the company said. Europe’s largest engineering company agreed in 2014 to invest 160 million pounds ($215 million) in a blade factory in Hull, Yorkshire and a rotor blade factory in nearby Paull to supply parts for its 7-megawatt offshore wind turbine.   While the factory is still on track to open in the coming months, the company has halted longer-term export plans until the U.K. government provides more clarity on how it will trade with the rest of the EU, the spokeswoman said by phone. The current order pipeline at the facility is for U.K. projects, she said. The story was first reported by the Guardian.   “The government must now move swiftly to unify and agree the nature of the U.K.’s relationship with the EU and other trading partners, creating clear roadmaps to encourage future investment,” Siemens said in an accompanying e-mailed statement.
