Grid Bottlenecks and Regulatory Shifts

Grid Bottlenecks and Regulatory Shifts

PJM curtailment proposal could cut power to new DCs without dedicated generation. EPA Clean Air Act exemption emerges as major regulatory signal, potentially accelerating off-grid builds but increasing environmental backlash. Transformer shortages, interconnection queues, and state-level moratoria continue to constrain build timelines. Massachusetts moratorium attempt fizzles, but local city actions (Lowell, Westfield) and 'bring your own clean energy' stance add to regulatory tug-of-war. Federal site conversion (Paducah uranium plant) shows government-as-landlord model to bypass grid bottlenecks. Small-town zoning details (closed-loop cooling, setbacks) add grassroots friction.
