In the wake of recent high-profile power failures, policymakers and politicians have asserted that there is an inherent tension between the aims of clean energy and grid reliability. But continuing to rely on fossil fuels to avoid system outages will only exacerbate reliability challenges by contributing to increasingly extreme climate-related weather events. These extremes will disrupt the power supply, with impacts rippling far beyond the electricity sector. This Article shows that much of the perceived tension between clean energy and reliability is a failure of law and governance resulting from the United States’ siloed approach to regulating the electric grid. Energy regulation is, we argue, siloed across three dimensions: (1) across s...
