About Us
Sentinel Power Services, Inc. was founded in December 1998 as switchgear repair and maintenance facility for industrial clients in the greater Tulsa, Oklahoma area.
SPS transitioned to being a NETA accredited electrical equipment testing, commissioning, and troubleshooting services provider, as well as supporting our clients with large motor expertise. As the company expanded to meet the growing needs from our customers, engineering capabilities were added to address our clients need for power systems analysis and P&C engineering.
Sentinel has developed into a multi-discipline firm with a complete suite of solutions and servcies to address the need for a design engineering firm with hands-on experience and field expertise. SPS is now an EPC company and field service firm capable of handling front-end engineering, design, procurement, construction, commissioning, and lifecycle maintenance and testing solutions.
