What Siemens Energy makes for data centers
public · HQ Munich, DE · siemens-energy.com
Siemens Energy makes large power transformers and HV switchgear and GIS, including SF6-free switchgear under its Blue line, for the substations that feed data center campuses. It also supplies gas turbines for onsite and behind-the-meter generation, HVDC and STATCOM equipment for grid interconnection, and large heat pumps used in data center heat-reuse and district-heating projects. It was spun off from Siemens in 2020 and includes the Siemens Gamesa wind business.
