Mesa is a woman/minority-owned full-service multi-discipline engineering, procurement, and construction management firm specializing in providing engineering services for the electric utility industry. We specialize in power generation and delivery services including electrical high-voltage, substation, switchyard, transmission line and distribution design. We differentiate ourselves by saying we are Large Enough to Perform, Small Enough to Care.

In addition to the standard PLC/HMI and DCS automation, Mesa is also an OSIsoft partner and authorized Cisco and Stratus high-availability server reseller. We have a vibrant Control Systems Integration department with an associated UL508A Control Panel Shop where we fabricate custom control panels, and Custom Machine-Build Shop where we design/build/automate custom machines, robots, and process skids. 

Mesa’s staff of automation experts, specializing in high-availability, hot-standby, and redundant applications, provides a full spectrum of services, from small work orders under $5K up to and including multimillion dollar enterprise-wide capital projects. Mesa’s CSA&I team is fully certified in a variety of hardware and software platforms and is affiliated with the Control Systems Integrator’s Association (CSIA) including having staff members on CSIA’s Best Practices Committee. A significant value Mesa offers is our experienced staff of multidiscipline engineers and designers, who support the CSA&I group as needed.
