A Coordinated Electric System Interconnection Review—the utility’s deep-dive on technical and cost impacts of your project.

Q1: What is a Load Flow Study?
A Load Flow Study (or power flow analysis) evaluates the steady-state operation of an electrical network, calculating voltages, active/reactive power flows, and system losses to ensure voltage stability and efficient power delivery.
Q2: Why are Load Flow Studies essential for HV/MV systems?
They help you:

Verify voltage compliance with ANSI/IEC standards
Optimize conductor sizing and transformer tap settings
Prevent overloads and voltage drops
Support protection coordination, arc-flash, and short-circuit studies
Plan for future DER or renewable integrations
Q3: Which software platforms do you use?
We leverage ETAP, Siemens PSS®E, and PowerWorld for scalable, high-fidelity simulations across HV and MV networks.
Q4: What data does Keentel need to begin?
Single-Line Diagrams (SLDs)
Bus & line impedance, length, ampacity
Transformer and generator specs
Load profiles (kW/kVAR)
Renewable resource data (PV, wind, BESS)
Contingency and switching scenarios
Q5: What are the typical deliverables?
Our detailed report includes:

Bus voltage profiles
Branch power flows & losses
Transformer loading & recommended tap settings
Color-coded one-line diagrams
System efficiency metrics
Actionable improvement recommendations
Q6: How often should studies be refreshed?
Update whenever you add major loads/generation or reconfigure the network—and at least every 3–5 years for critical or NERC-jurisdictional facilities.
Q7: Do you handle renewable interconnection studies?
Yes. We perform load flow analysis for solar, wind, and utility-scale BESS interconnections, ensuring compliance with ISO and utility requirements.
Q8: Are load flow studies required for permitting?
Often—utilities, ISOs, and permitting bodies typically mandate power flow analysis for grid impact assessments and interconnection approvals.
Q9: Can load flow be integrated with other studies?
Absolutely. We bundle Load Flow with Short-Circuit, Protection Coordination, Arc-Flash, Harmonics, and Stability analyses for turnkey project support.

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

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.
