The Designers
18 Engineers
They turn lines into lifelines. With tools like AutoCAD, Revit, ETAP, PVSyst, and CAD 3D, they translate ambition into design—calculating, modeling, and detailing systems that work the first time.
At Keentel Engineering and its Consultants, our mission is to establish a sustainable business that delivers top-notch technical services to meet the unique needs of our valued clients.
At Keentel Engineering, we deliver electrical power engineering services built on 30 years of experience and a commitment to excellence. Our clients include utilities, developers, EPCs, and public agencies across the U.S.
Unlike firms that sacrifice technical depth to chase billable hours, we prioritize precision, compliance, and value engineering. From transmission services and relay modeling to winterization and SCADA planning, we never compromise on quality.

In 1995, Sonny Patel earned his Electrical Engineering degree from the University of Illinois. But degrees don't build legacies — action does.
For three decades, he has worked the power industry from every side of the table: 16 years as a utility engineer at Exelon/Commonwealth Edison; generation leadership across hydroelectric, industrial steam turbine, and a 9 GW renewable fleet; NERC Regional Entity Senior Compliance Engineer and Audit Team Lead, auditing some of the nation's largest utilities; and testing and commissioning lead on equipment up to 765 kV — the very top of the North American grid.
Utility. Generator. Regulator. Consultant. Few engineers have seen all four seats. Fewer still have sat in them.
His experience spans nuclear, hydro, conventional generation, renewables, oil and gas, mining — and today's data centers, where he is authoring a three-book series on data center design.
He is a Licensed Professional Engineer in six states and a Licensed Electrical Contractor in Florida (Unlimited EC) — he doesn't just design the work; he's qualified to stand behind its execution.
Today, as Founder and CEO of Keentel Engineering, Sonny leads 51 engineers delivering substation design, power system studies, NERC compliance, and commissioning — done right, coast to coast. Three decades. Every side of the table. One standard: accountable engineering.

Multidisciplinary engineering support for power systems, substations, interconnection, transmission, renewables, compliance, and complex electrical infrastructure.

Power system analysis, modeling, and simulation to support reliable operation, grid integration, system performance, and informed engineering decisions.

Electrical engineering and design support for reliable, safe, coordinated, and constructible substation infrastructure across complex power projects.

Engineering support for NERC compliance, technical documentation, assessments, reliability requirements, audit preparation, and regulatory readiness.

Our experienced engineering team supports complex grid interconnection projects with technical studies, substation coordination, utility requirements, and commissioning support.

Electrical engineering support for utility-scale solar, wind, and energy storage projects, including system design, technical studies, and grid integration.

Transmission line engineering for complex power infrastructure, including route optimization, structural modeling, conductor design, sag-tension analysis, and construction-ready deliverables.

Specialized electrical engineering support for nuclear power facilities, including safety-class power systems, protection coordination, equipment upgrades, compliance, and diagnostics.
