Policy, Renewables, and Who Is Responsible If The Grid Fails with Meredith Angwin | TGS 196

Video Description

(Conversation recorded on September 17th, 2025) For many people in the modern world, electricity powers everything we do. Yet we take for granted how power flows in the background, seemingly always accessible to us just by flipping a switch. In fact, most of us are completely unaware of what it takes to generate and transmit the power we so deeply rely on, let alone the policy decisions shaping our electrical grids – or how they might affect reliable access to power. How do today’s electrical grids actually work, and do they align with our long-term goals for human and planetary well-being? In this episode, Nate is joined by Meredith Angwin for an in-depth overview of the U.S. electrical grid system, its history, and the need for accountability in energy governance. Meredith discusses the infrastructure of the grid, the complexities of grid management, and the implications of shifting to market-based systems. Additionally, she emphasizes the critical importance of resource adequacy and reliability – and the barriers to that in our current policy landscape. How has the increased use of renewables and natural gas affected the broader dynamics of the grid? If the electrical grid were to fail, who is responsible for the problem, and who should fix it? Ultimately, what variables do we need to consider as we attempt to provide dependable electricity for everyone without jeopardizing the stability of the Earth? About Meredith Angwin: Meredith Angwin studies and takes part in grid over-sight and governance. For four years, she served on the Coordinating Committee for the Consumer Liaison Group associated with ISO-NE, her local grid operator. She also teaches courses and workshops on the electric grid, and wrote a book titled, Shorting the Grid: The Hidden Fragility of our Electric Grid, analyzing the electrical grid from a physical science and policy perspective. As a working chemist, Meredith Angwin headed projects that lowered pollution and increased reliability on the electric grid. Her work included pollution control for nitrogen oxides in gas-fired combustion turbines, and corrosion control in geothermal and nuclear systems. Further, she is an inventor on several patents and was one of the first women to be a project manager at the Electric Power Research Institute where she led projects in renewable and nuclear energy.
