NMM was founded by General Electric retirees who are experts on steam turbines, aeroderivative, heavy duty gas turbines we offer expert
field service personnel for power plants. (Combustion, performance, hot gas path, accessories, etc.), generators, stator rewinding, rotor rewinding,
compressors, power plant mechanical, electrical, excitation, control etc. We are not limited to the General Electric machine and can handle Siemens, Alstom and other OEMs.
NMM Energy helps your business with all aspects of the total Electrical plant and Mechanical life cycle and Building Construction. We can help support site
and project development, provide detailed analysis of proposed systems, performance enhancements, and configuration optimization for existing plants NMM Energy
can help solve small problems to complex system issues, such as Electrical, Excitation upgrades, Mechanical upgrades, Controls upgrades, Motor Control Center,
Battery system, Fire protection, Substation, Switch Yard, Building Electrical and much more. For mature plants, contact us to find out how your asset could not only
continue to operate, but with improved performance and availability.
NMM Energy draws upon a broad spectrum of engineers with backgrounds in every aspect of power plant design, operations, maintenance, project management,
project development, life extension, and performance improvement. Each engineer brings a minimum of 10 years experience. NMM Energy engineers can help you with everything
from individual components to total plant systems.
The engineering staff of NMM Energy has extensive experience providing engineering support to customers with
installed Heavy-duty gas turbines can operate much longer than the original design intent. Customers needs frequently change as well over time due to regulatory constraints, fuel cost, power & efficiency needs, HGP parts cost, and need to keep an existing
plant in operation far longer than originally intended.
Thus, the NMM Energy has brought together a large group of very experienced engineers to help customers with all their needs to study and implement required changes.
