Move past SKM PowerTools to something modern
SKM PowerTools has served the industry for decades. But the interface feels dated, the setup is painful, and the price keeps climbing. ekx gives you the core analyses you use most — in a modern, browser-based tool.
What you get
SKM's interface hasn't changed much since the 2000s. ekx is built with modern web technology — fast, clean, and responsive.
SKM requires installation, compatibility checks, and often IT support. ekx is a browser tab.
SKM requires you to set up each study. In ekx, load flow and sizing update as you build, and short circuit runs in one click.
SKM costs $2,800–8,000/year. ekx starts free, with paid plans at $27/month (Starter) or $149/user/month (Professional).
No more saving .dts files and emailing them. Your work is in the cloud, always accessible.
Auto equipment sizing per NEC is built in — not a separate module or add-on.
What ekx does differently than SKM
SKM PowerTools is a legacy Windows application. ekx is a ground-up rebuild of the core analyses engineers need most, designed for how people actually work today.
- No installation, no compatibility issues — works in any browser
- Load flow updates as you build the model; short circuit runs in one click
- Equipment sizing per NEC is included, not an add-on
- Modern interface that's intuitive without a training course
Start free. Upgrade when you need more.
Free tier includes 1 project with up to 2 buses. Paid plans start at $27/month for consultants and $149/user/month for unlimited access.

For short circuit, load flow, arc flash, and equipment sizing, often yes. ekx plots protection device curves and runs harmonic design checks, but it doesn't do full protection coordination studies. For the core analyses, ekx is faster and more affordable.
SKM PowerTools typically costs $2,800–8,000/year depending on modules. ekx Professional is $149/user/month, or $1,490/user/year billed yearly, with all features included. No module fees.
ekx is designed to be intuitive. Engineers typically build their first project and run studies within minutes, not days.
Direct SKM file import is not available. You can rebuild models in ekx using drag-and-drop, or import device data via CSV.
