Transmission

In addition to introductory information on transmission in the U.S., this briefing book is broken down into four sections. First, we will examine how to better understand transmission and the opportunities presented by the “Three P’s of Transmission” (Planning, Permitting, and Paying). Second, we will examine how to maximize the capacity and ability of existing processes and infrastructure. Third, we will highlight ways to create new entities and authorities to better coordinate and streamline transmission development. Lastly, we will demonstrate how best to incorporate public interests into transmission policy to ensure that all communities benefit equally from this work.

Grid-enhancing technologies (GETs) and advanced reconductoring, the energy efficiency tools of the power grid, can help increase the capacity of the grid faster and without building new lines. By increasing the capacity of existing lines, the grid can transmit more electricity without the lengthy planning and permitting process required for new transmission build. While construction of new transmission will still be needed to support the U.S. energy transition, these…

As the grid ages and extreme weather events like wildfires become more prominent, the relationship between them grows increasingly strained. Grid failures can trigger wildfires, while wildfires and the increased fire risk can, in turn, cause more grid failures, creating a vicious cycle. To reduce wildfire risk, some utilities are adopting strategies such as adjusting grid control settings, implementing public safety power shut-offs during high-risk weather, vegetation management, and worker protocols for dry conditions. State legislators can encourage utility adoption of these wildfire mitigation risk strategies and plan for future wildfire risk.
