Second is the . The electromagnetic physics engine behind CDEGS has been refined over four decades. Unlike mass-market software with millions of users to amortize development costs, SES serves a relatively small, global audience of high-value specialists. The company also provides world-class technical support directly from its engineers—a service that is factored into the license price.
In conclusion, the price of CDEGS software is not simply a fee; it is a strategic investment. The $30,000 to $80,000+ price tag (including long-term maintenance) effectively filters its user base to only those organizations for whom precise electromagnetic simulation is a core, non-negotiable business function. For a major utility or a multinational engineering firm designing critical infrastructure, the cost is readily justified by the risk reduction, regulatory compliance, and liability protection it provides. For everyone else, the high price of the gold standard serves as a firm barrier to entry—a reminder that in high-stakes engineering, precision and safety come at a premium.
Of course, this pricing strategy has consequences. For small engineering firms, independent consultants, or academic researchers, the cost is often prohibitive. Many resort to rental options, which SES does offer, though these are still expensive (often thousands per month). Others turn to less capable but more affordable alternatives like open-source soil simulation tools, general-purpose FEM software (e.g., COMSOL), or more budget-oriented grounding packages (e.g., ETAP’s grounding module). However, for any project requiring rigorous certification or involving complex fault current distribution, the engineering adage remains true: you get what you pay for.
In the specialized field of electrical engineering, particularly concerning power systems, grounding, and electromagnetic compatibility, few names carry as much weight as CDEGS. Developed by Safe Engineering Services & Technologies Ltd. (SES), the Current Distribution, Electromagnetic Fields, Grounding, and Soil Structure Analysis software is the undisputed gold standard for simulating complex electromagnetic scenarios. However, for any firm or consultant looking to acquire this powerful suite, the first and most formidable obstacle is not a technical one, but a financial one. CDEGS software is notoriously expensive, operating on a bespoke, quote-based pricing model that places it firmly in the realm of high-stakes industrial and utility investment, far beyond the reach of casual users or small startups.
