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—on time, every time.
Substations are where generation meets the grid—and where precision is non-negotiable. From 69 kV distribution to 500 kV transmission facilities, our crews deliver with safety, schedule certainty, and proven performance.
- New substation construction (distribution and transmission)
- Expansion and retrofit projects for renewable integration
- Transformer installation and high-voltage equipment setting
- Bus work, control wiring, and relay panel installation
- Protection & control testing
- POI integration for renewable generation and battery storage
- Grid hardening for storm resilience
