Nexus Controls. We’ve been here all along


Nexus Controls was rebranded as part of Digital Solutions at Baker Hughes back in October 2019. However, the Nexus Controls story began long before that. Our business today exists as the collective experience and history of multiple companies whose lineage spans 150 years.

Beginning with The Woodward Governor Company and encompassing longstanding relationships and synergy with General Electric and Baker Hughes, the entire Nexus Controls story demonstrates our intense focus on innovation, customer relationships, and measurable outcomes – the three pillars of our historical success.   

Our unique history is what made us a leader in the energy technology, industrial controls, DCS, safety systems, and cybersecurity markets. It is important to us because it is who we are. 

And although you might not know us by name… we’ve been here all along.





Turbine Control Systems


Industrial Distributed Control Systems
Generator Control & Excitation Systems

Our dedicated team of engineering and service professionals specialize in generator control and protection systems. We have decades of experience supplying excitation modernizations for heavy duty and aeroderivative gas, industrial and large steam, and hydro powered turbine-generators to customers worldwide.

As regulatory and operational requirements evolve, many legacy generator control systems are limited by the technology of their era and require upgrades to improve the performance, security and compliance of generating assets. Aging generator controls represent an increased operational risk over time and our team can help owners to develop comprehensive hardware, software, design and installation solutions optimized to meet their specific needs.

Whether a “controls only” migration, a standalone excitation replacement or as part of an integrated plant control retrofit project, our team can provide a single point of responsibility to deliver a successful retrofit across a wide variety of generator and control manufacturers and applications.
