Data centres are rewriting the distribution demand queue

Accepted connections at the higher distribution voltages doubled from 2024 to 2025, with single sites seeking 80MW to 350MW of import capacity. Hard to see what else that could be but AI data centres, and hard to overstate the build-out it implies.
