The company said construction would be finalised next year followed by a production ramp up at the site, first established in 2022.
The focus of the enlarged factory will be production of 115-metre-long blades for 14MW turbines, for which Siemens Gamesa says it has more than 16GW worth of firm orders.
The OEM has installed 1GW offshore wind power in France and is set to reach 2.5GW with additional projects in the pipeline.
Siemens Energy France MD Yara Chakhtoura said: “The investment announced today confirms the importance of our French manufacturing site as a strategic production facility for the growth of the offshore wind market. We are expanding our capacity by strengthening the skills and infrastructure we already have locally.
“With this investment and expansion of our factory in Le Havre, France and Europe continue to play an integral role in Siemens Gamesa’s development, manufacturing, and installation of offshore wind turbines.
“We thank the French government and the European Union for their focus on the green energy transition. It benefits the entire French value-chain in offshore wind and strengthens European competitiveness in energy transition.”
