Powering the Grid’s Future

Building the Backbone of the Grid

Utility-scale renewable integration demands precision. Cinterra builds substations, interconnections and hardened grid systems that keep power flowing reliably and efficiently.

​

Substations are where generation meets the grid, and precision is non-negotiable. From 69 kV distribution to 500 kV transmission facilities, our crews deliver with safety, schedule certainty and proven performance.
