IID Transmission Backbone

CHOKEPOINT — existing transmission capacity is the binding constraint on how much new generation can actually reach industrial load, regardless of how much power is produced.

Transmission backbone chokepoint

New geothermal and solar generation cannot reach industrial load faster than the transmission backbone can be upgraded — the chokepoint is transmission capacity, not generation capacity. This constrains the power arm, the semiconductor candidate site, and the battery materials candidate site simultaneously.

This entity is not a dependency of any scenario yet.

Scope transmission backbone upgrade study

Determine the scope and cost of a transmission backbone upgrade before committing to semiconductor or battery-materials siting, since power generation alone will not resolve the constraint.
