Short-Circuit Studies
Fault current calculations to verify equipment interrupting ratings are adequate. Required when adding new equipment, upgrading service, or when utility fault current levels have changed.
ANSI/IEEE · NFPA 70 NEC
Coordination Studies
Time-current curve analysis to ensure protective devices operate in the correct sequence. Critical for facilities with multiple sources, generators, or complex distribution systems.
IEEE 242 · NFPA 70
Harmonic Analysis
Power quality studies for facilities with VFDs, motor controls, or non-linear loads. Essential for Texas wastewater treatment plants, manufacturing facilities, and data centers.
IEEE 519 · IEEE 1159
Load Flow Analysis
Steady-state power flow studies to identify voltage regulation issues and verify equipment loading. Critical for planning electrical infrastructure expansions and additions.
IEEE 399
Duct Bank Heat Studies
Cable ampacity calculations for underground duct banks using CYMCAP, required for large commercial developments, utilities, and medium-voltage underground distribution projects in Texas.

Texas Power Landscape
The Grid We Engineer For in Texas
Every power system study TPS delivers in Texas accounts for the utilities, fault duties, and interconnection requirements specific to the state. This is the landscape our Texas work sits in.
Most of Texas runs on its own wholesale grid, ERCOT (the Electric Reliability Council of Texas), which covers roughly 90% of the state load and is overseen by the Public Utility Commission of Texas. The Panhandle and parts of north and east Texas sit in SPP, a sliver of far east Texas (the Beaumont area, served by Entergy) sits in MISO, and El Paso sits in the Western Interconnection (WECC). In the deregulated ERCOT regions, the wires are owned by transmission and distribution utilities — Oncor, CenterPoint, AEP Texas, TNMP — while municipal utilities like Austin Energy and CPS Energy serve their own territories. The available fault current at any facility service is set by the serving utility and can shift when that utility upgrades transformers, ties, or substations, which is why short-circuit and arc flash studies should be revisited after any utility-side work.
Texas does NOT operate a state OSHA plan. Every employer in the state, public and private, answers to federal OSHA, which enforces electrical safety through 29 CFR 1910 Subpart S and treats NFPA 70E as the consensus standard for arc flash risk assessment and equipment labeling. A current, PE-sealed arc flash study is the documentation a federal OSHA inspector or an insurance auditor expects to see.
The authority having jurisdiction for the installation itself is typically the local or county electrical inspection office enforcing the National Electrical Code as adopted in Texas. Every study True Power Systems delivers in the state is modeled to current IEEE and NFPA methodology and sealed by a Professional Engineer licensed in Texas.

Texas FAQ
Texas Power System Study Questions
Who enforces arc flash compliance for Texas facilities?
Texas has no state OSHA plan, so all employers in the state, public and private, answer to federal OSHA. Federal OSHA enforces electrical safety through 29 CFR 1910 Subpart S, which references NFPA 70E for arc flash risk assessment and equipment labeling.
Does my Texas facility need an arc flash study?
If workers ever interact with energized equipment — troubleshooting, racking breakers, voltage testing — NFPA 70E calls for an arc flash risk assessment and OSHA expects equipment to carry incident-energy labels. New equipment, a service upgrade, or a change in utility fault current all trigger a new or updated study.
How does Texas's grid affect my power system study?
Most of Texas runs on ERCOT, its own grid; the Panhandle is in SPP, far east Texas is in MISO, and El Paso is in WECC. In deregulated ERCOT areas the wires belong to Oncor, CenterPoint, AEP Texas, or TNMP, while Austin Energy and CPS Energy serve their own territories. The fault current available at your service comes from the utility and changes when the utility upgrades equipment, so short-circuit and arc flash results should be re-checked after utility-side work.
Who can seal a power system study in Texas?
A power system study used for compliance must be sealed by a Professional Engineer licensed in Texas. True Power Systems holds an active Texas PE license and stamps every Texas deliverable.
What does a Texas power system study include?
A complete package covers incident-energy calculations and arc flash boundaries, ANSI Z535 equipment labels, short-circuit and equipment-duty evaluation, protective-device coordination, an as-studied one-line diagram, and a PE-sealed report.
