For nearly three decades, electric power planning operated under a relatively stable planning paradigm: modest load growth, predictable asset replacement cycles, and infrastructure expansion paced over years rather than months. Today, that playbook is being tested by a very different set of system conditions.

Data center expansion, industrial reshoring, and rapid electrification are forcing power system planners to confront a sharp surge in load growth. At the same time, many substations, transformers, and feeders are aging or approaching thermal and operational limits.

The default industry reaction has been to accelerate traditional infrastructure investment: proposing new generation, expanding high-voltage transmission, and upgrading substations. Supply-side expansion remains essential, but relying primarily on new capital infrastructure creates structural bottlenecks across development timelines, supply chains, permitting processes, and customer bills.
