What SKM Systems Analysis does

SKM Systems Analysis, Inc. is a privately held California-based software company founded in 1972 that develops and sells Power*Tools for Windows (PTW), a comprehensive suite for electrical engineering power system analysis and design. PTW bundles more than fifteen integrated study modules covering fault analysis (ANSI and IEC 60909/61363), load flow, demand load, coordination, arc flash hazard evaluation (compliant with NFPA 70E, IEEE 1584, and NESC), motor starting, transient stability, harmonics, grounding, cable ampacity and pulling, reliability, and DC system analysis. The platform is supported by a deep content library of protective devices, bus ratings, and clothing levels, and is sold under perpetual licenses with optional maintenance subscriptions, supplemented since 2025 by MySKM Cloud ($1,500/yr) and the SKM Mobile App ($299/yr per user) for iOS and Android.

The company sells primarily through a direct, sales-led motion via the MySKM portal, with mobile distribution through Apple App Store and Google Play Store, and offers in-person training in Houston and Los Angeles. Its customer base spans the top 40 electrical engineering firms globally, marquee OEMs and engineering firms including Cutler-Hammer, GE, Square-D, and Siemens Westinghouse, and a cumulative installed base of over 45,000 engineers serving commercial, light and heavy industrial, institutional, utility, and petrochemical sites worldwide. The product roadmap in 2025 has emphasized standards compliance (IEEE 1584-2018), platform modernization (PTW v11.0.1.0), ecosystem buildout (mobile + cloud + field data collection), and entry into automated design via the new Auto Design module.

SKM operates with a small team of 11–50 employees, distinguishing itself through technical support staffed entirely by electrical engineers (over 20% holding registered Professional Engineer certifications). The company is privately held with no disclosed parent, institutional investor, or M&A activity, and generates revenue primarily through one-time PTW licenses, maintenance subscriptions, training services, and the newer recurring cloud and mobile subscriptions.

Direct peers

• ETAP (Operation Technology, Inc.): ETAP is the closest direct competitor to SKM Power*Tools, offering integrated electrical power system modeling, simulation, and arc-flash analysis on a unified platform for the same engineering consultancy and industrial customer base.
• EasyPower (Bentley Systems): EasyPower is a direct competitor to SKM Power*Tools for fault, coordination, arc flash, and power-flow studies, now owned by Bentley and tightly integrated with broader infrastructure design software — selling to the same electrical engineering customer base.
• DIgSILENT PowerFactory: PowerFactory is a direct competitor to SKM in power system analysis (load flow, short circuit, harmonic, stability) with stronger presence in European transmission utilities, addressing the same core fault/coordination/arc-flash workflows.
• PowerWorld Simulator: PowerWorld Simulator competes head-to-head with SKM Power*Tools on power flow, contingency analysis, and visualization for utility and consulting engineers, including a free viewer version that functions as a partial substitute for SKM's PTW Viewer.
• PSCAD (Manitoba Hydro International): PSCAD competes with SKM's I*SIM and HI_WAVE modules on electromagnetic transient and harmonic analysis, targeting power systems engineers who need time-domain simulation of the same fault and switching events analyzed by SKM.
• Siemens PSS®E: Siemens PSS®E is a competing transmission planning and power-system analysis suite sold by a SKM customer (Siemens Westinghouse) into the same utility and large-industrial account base, making it both a partner and a competitive threat.

Broad incumbents

• MathWorks Simulink + Simscape Electrical: MathWorks is a broad incumbent engineering-simulation platform whose Simscape Electrical toolbox overlaps with SKM's transient-stability and motor-starting modules; engineering firms increasingly use Simulink as a multi-physics platform that can partially substitute for SKM's specialist studies.
• Bentley Systems: Bentley owns EasyPower (a direct competitor) and bundles it into a broader infrastructure engineering and digital-twin portfolio, putting downward pressure on pure-play specialists like SKM by offering electrical analysis inside a wider platform sale.

Emerging players

• ATP-EMTP (open-source EMTP): The ATP-EMTP program is an open-source emerging alternative for electromagnetic transient and fault studies that overlaps with SKM's I*SIM and short-circuit modules, especially attractive to academic and budget-constrained utility users.
• ETAP-DIGSILENT academic ecosystem: University-licensed editions from ETAP and DIgSILENT create an emerging pipeline of engineers pre-trained on competitor tools, representing a long-term substitution risk for SKM at the entry point of the consulting workforce.
