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 run studies explicitly. ekx calculates short circuit, load flow, and sizing live as you build.
SKM costs $2,800–8,000/year. ekx starts free, with paid plans at $27–149/month.
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
- Short circuit and load flow update live as you build the model
- Equipment sizing per NEC is included, not an add-on
- Modern interface that's intuitive without a training course
