BERLIN, May 21 (Reuters) - Siemens Gamesa has signed an agreement to sell its 32% stake in Windar Renovables to Bridgepoint, a spokesperson for Siemens Energy , Siemens Gamesa's parent, said on Sunday.

The spokesperson declined to comment on the price for the sale of the stake in Windar, a Spanish maker of towers for wind turbines.

“The sale of Siemens Gamesa’s stake in Windar is a natural decision for us, as part of our strategy to focus on our core business: wind turbine design, manufacturing including blades, installation and maintenance," Siemens Gamesa CEO Jochen Eickholt said.
