German energy technology company Siemens Energy said it will invest $150 million to expand its operations in Charlotte, North Carolina, in a move set to create almost 600 local jobs. In Charlotte, the company will add to its current operations by building the first Siemens Energy Transformer production facility in the US. Also, the project will be supported by a Job Development Investment Grant from the state of North Carolina, the company said. Construction of the factory will begin in this year with the first transformers set to be manufactured in early 2026, the company said.
