America's power grid was built largely in the mid-twentieth century for a world that no longer exists. Today it faces electricity demand rising at the fastest rate in decades, driven by data centers, electric vehicles, and manufacturing reshoring. The grid must connect 2.6 terawatts of new power projects—more than twice its current capacity—but new transmission lines take a decade or more to build.
CTC Global and Google's new GridVista system offers a different path. By embedding fiber-optic sensors in power line conductors and using AI to process the data, utilities can see how much electricity their wires safely carry in real time—and that's substantially higher than they thought. GridVista enables utilities to push up to 120% of previous rated capacity through existing infrastructure, unlocking power delivery that was always physically possible but previously invisible to operators.
