GridIntellect and co-authors John Cooper and Eamonn McCormick provide a three-part series on the role of Public Power in decarbonizing and electrifying our society and economy. In the first article we establish the clear imperative to decarbonize and what that means for Public Power. In Part 2, we review the Crisis of Slow Public Power Decarbonization. In Part 3, we connect the dots between decarbonization and distributed energy resources (DER), showing a second imperative for public power: integrating DER into utility grid modernization. As we continue this series, we’ll explore a wide variety of impacts, constraints, risks, costs and benefits, including supply chain issues, the broad impact of decarbonization on our society and economy, and the upsides of an Electrify Everything Economy.
