Have you completed a power supply upgrade recently? Are you sure it was required?


Many of the projects we assess reveal that a power supply upgrade is often unnecessary. Upgrading a site’s electrical supply capacity beyond what is required can lead to unnecessary upfront expenses and ongoing long-term costs such as excessive line and capacity charges.


At SEG, our electrical team specializes in comprehensive electrical maximum demand assessments to ensure your infrastructure meets current and future demands without over-engineering. Our clients will tell you that our detailed and professional services help identify potential issues before they become costly problems, providing peace of mind.
