What is the main practical difference between ETAP and SKM?

ETAP is built around one integrated one-line diagram that feeds every study module and offers a broader catalog of specialty studies (transient stability, harmonics, DC systems, real-time/SCADA integration). SKM PowerTools grew up as a family of more distinct programs (DAPPER, CAPTOR, Arc Flash Evaluation) sharing a common database, historically known for a fast, purpose-built coordination and TCC-plotting workflow. Both cover load flow, short circuit, arc flash, coordination, and motor starting equally well.

Which industries use ETAP versus SKM?

ETAP is more common at utilities, EPC firms, and heavy industrial owner-operators (oil & gas, petrochemical, mining) running large, continuously operating systems that benefit from its specialty modules and real-time integration. SKM PTW has a long-established base among electrical consulting engineering firms whose recurring deliverable is coordination studies and arc-flash labeling for commercial, healthcare, data center, and industrial facilities. Both patterns have plenty of exceptions.

Is SKM PowerTools the same thing as DAPPER and CAPTOR?

DAPPER (load flow and short circuit) and CAPTOR (protective device coordination) are individual program modules within the SKM PowerTools for Windows (PTW) suite, alongside an Arc Flash Evaluation module and others. "SKM" and "PTW" both commonly refer to the overall suite; DAPPER and CAPTOR are specific modules within it.

Does Bentley Systems own SKM now?

Yes. Bentley Systems acquired SKM Systems Analysis in 2021, and SKM PowerTools is now positioned within Bentley's broader infrastructure and digital-twin software portfolio.

Which is cheaper, ETAP or SKM?

Neither vendor publishes fixed public pricing — both quote based on modules licensed and seat count. As a general pattern, a fully-loaded ETAP setup with specialty modules costs more, reflecting its broader specialty-study catalog, while a firm only needing core load flow/short circuit/coordination/arc-flash capability can often license SKM's core modules for less. Get a current quote from each vendor rather than budgeting off general reputation.

Can I convert an ETAP model to SKM or vice versa?

No — neither platform opens the other's native project file, since each stores one-line and study data in its own proprietary database. Switching platforms generally means rebuilding the one-line diagram from source design data (nameplate data, cable schedules, protective device settings) rather than migrating an existing model directly.

Two Platforms, the Same Core Job

ETAP and SKM PowerTools for Windows (PTW) are the two commercial platforms most electrical engineers will actually encounter on the job when a project calls for power system modeling rather than hand calculations or a single-point calculator. Both build a digital one-line diagram of a distribution system and run the same broad categories of studies against it. Neither is a "better" tool in the abstract — the honest answer is that they represent two different design philosophies for the same underlying problem, and which one a given engineer uses is usually decided by their employer or client long before it's decided by feature comparison. If you're new to ETAP specifically and want a getting-started walkthrough of building a one-line diagram and running a load flow study, see ETAP Tutorial: Getting Started with Power System Analysis Software — this article assumes that background and focuses on how the two platforms actually differ.
