Rannou was most recently chief executive of GE Renewable Energy's hydro division, following the US conglomerate's takeover of the power and grid business of Alstom.
He will step in to the new role from March 2019 "at the latest", the firm said.
He also held the role as senior vice president of Alstom's wind unit between January 2014 and October 2015.
Rannou has also managed Alstom's hydro business in China.
He replaces former Senvion CEO Juergen Geissinger who quit the manufacturer in May 2018 expressing the desire for new challenges following the completion of the company’s restructuring, global expansion, and successful initial public offering (IPO).
Senvion had been led by CFO Manav Sharma while a recruitment process took place, supported by CSO David Hardy. They will continue to lead the company, until Rannou joins.
The manufacturer's chairman, Steven Holliday, said: "Yves is a proven executive whose skills and expertise ideally complement the existing management team. We are confident that he is the right leader to execute Senvion's growth strategy and position the business for future success."
"I am thrilled and honoured to be joining Senvion at a truly exciting time for the wind industry. Senvion has a long and successful track record as a major contributor to the energy transition," Rannou said of his new role.
"Senvion's value proposition, its customers and suppliers, and most importantly our team are great assets for further international expansion, sustainable growth and value creation for our partners," he added.
