Project overview
Certain Grid Engineering is delivering complete engineering, procurement support, and commissioning for two 345 kV / 34.5 kV substations in Texas, working through an EPC for a major investor-owned utility.
These are full-scope projects. We’re responsible for every engineering discipline — general arrangement and physical design, protection and control, SCADA, structural engineering, and equipment procurement — and we’ll lead commissioning at both stations.
Highlights
- Extra-high-voltage design at 345 kV, one of the highest voltage classes in the U.S. transmission system
- Every discipline from site arrangement through commissioning, delivered by one firm
- Bid-ready equipment specifications and procurement support for long-lead HV equipment
- A North Carolina team delivering utility-grade work in Texas

We’re glad to talk through a project at any stage — including the ones that are still just a one-line on a whiteboard.
