4 snips Aug 21, 2023
Julia Simon, NPR's climate solutions reporter, dives into the outdated state of the U.S. electric grid and the urgent need for modernization. She discusses how many transmission lines rely on century-old technology, leaving thousands of renewable projects in limbo. Julia highlights innovative tech solutions, like using LiDAR sensors to optimize electricity flow, and the potential of the Inflation Reduction Act to expedite change. The conversation reveals exciting ways to revitalize the grid efficiently and economically, addressing the country's growing energy demands.

Episode notes
Folsom Transmission Tower
- Julia Simon visited Folsom, California, and observed a transmission tower with John Marmillo.
- Marmillo, whose company LineVision installs sensors on power lines, believes these lines can transmit more power.
Real-Time Grid Conditions
- Utilities control electricity flow but don't always know the lines' real-time conditions (wind, temperature).
- This lack of data forces them to use conservative power limits, potentially underutilizing the grid's capacity.
LiDAR Sensors
- LineVision uses LiDAR sensors on power lines to measure sag and sway, indicating wind conditions.
- This data allows utilities to safely increase power transmission, with some seeing up to 30% gains.
