About this episode

In this week’s episode, host Kristin Hayes is joined by University of Michigan Associate Professor Johanna Mathieu, who researches the efficiency and environmental impacts of the electric power sector. By breaking down how electricity is supplied in the power system, Mathieu demonstrates how understanding the potential areas of flexibility in power consumption can point to system-level improvements for when energy demand is straining the electric grid. Mathieu’s research has explored how data centers themselves can be sources of capacity flexibility and be a tool to reduce congestion on the electric grid, if coordinated properly. While engineering allows for a technical understanding of…
