If the grid system is the backbone of a low-carbon economy, then transmission lines are the nervous system. We need a dramatic build-out of the transmission system to connect renewable energy to the places that need it, while managing a wider range of local resources. How do we build it quickly, cheaply, and in a respectful way? In our third episode of season 3, Dr. Melissa Lott explores the role of transmission in decarbonizing the grid system. We’ll explore how Texas used transmission to encourage rapid uptake of wind power, and revitalize rural communities in the process. We’ll also look at the role of the grid system during extreme events, like Texas’ recent winter grid disaster. Guests: Greg Wortham and Cheryl LaFleur.
