The Invisible Grid Build-out

Everyone talks about how slow it is to build new transmission lines. Less noticed is how much capacity is being freed — right now — on the wires we already have. Three families of “grid-enhancing technologies” (GETs) are scaling fast: (1) advanced reconductoring with modern high-performance conductors that can double capacity within existing rights-of-way; (2) dynamic and ambient-adjusted line ratings (DLR/AAR) that raise safe operating limits based on real weather, not worst-case assumptions; and (3) power-flow control, topology optimization, and other software tools that route power away from bottlenecks to under-used lines. Together, these are connecting more renewables, cutting curtailment and congestion, and buying precious time while big new lines are planned and built.

GETs complement — not replace — new transmission. They reduce congestion and keep projects moving while long-lead lines, HVDC backbones, and interregional upgrades work through siting and permitting.
