Load growth can help modernize grid, but cost-shift risks are significant: Concentric

Grid growth from large loads could modernize power systems — if costs are shared

The report says large loads can justify new transmission and grid technology investments.
Misallocated fixed costs could shift $120 billion to $169 billion onto other customers over 30 years.
Concentric argues on-site generation may help temporarily but is not a durable long-term substitute for grid integration.

Defensibility by design: What FERC Order 1920 requires

Why FERC Order 1920 Could Reshape Long-Term U.S. Grid Planning

FERC Order 1920 requires transmission operators to plan at least 20 years ahead and update those plans every five years.
The rule mandates multiple plausible scenarios and consideration of grid-enhancing technologies.
It also raises the bar for transparency, requiring planning decisions that can be explained and defended to stakeholders.

Steering Electricity: How Grid Control Devices Unlock Transmission Capacity - CleanTechnica

Grid Control Devices Quietly Unlock Transmission Capacity

Grid control devices unlock 10-30% more capacity on existing transmission lines in months vs years for new construction
Dynamic line rating adjusts operating limits based on real-time weather rather than worst-case assumptions
Regulatory frameworks that reward new infrastructure investment can create disincentives for cheaper grid optimization
