What We Do
Your independent advocate
for quality and performance.
TerraWatt provides comprehensive Commissioning Management services. We act as your specialized Commissioning Agent (CxA), coordinating the entire quality assurance process.
Unlike testing contractors who focus on individual components, we take a holistic view — managing the schedule, creating checklists, leading meetings, and ensuring the design intent is fully realized in the final build.
