What's Happening?
The Energy Systems Integration Group (ESIG) has released a report emphasizing the need for significant reforms in transmission planning to improve the reliability and efficiency of the U.S. electric grid. The task force highlights that without these reforms,
the grid could face increased costs, slower asset delivery, and heightened risks to reliability and resilience. The report suggests that transmission planners should adopt long-range, scenario-based strategies as outlined in the Federal Energy Regulatory Commission’s Orders 1920 and 1920A. Key recommendations include integrating grid operations with planning, synchronizing generator and large load interconnection with long-term planning, and aligning asset-management programs with these plans. The report also stresses the importance of early and frequent consultation with state officials to avoid late-stage project surprises and to build a shared understanding of project needs.
Why It's Important?
The proposed reforms are crucial for maintaining grid reliability and supporting the growth of domestic industries such as artificial intelligence and semiconductor manufacturing, which are vital to the U.S. economy. The current pace of building new transmission infrastructure is insufficient, with only 1,600 miles of high-voltage transmission added in 2024 compared to 3,300 miles in 2013. This slowdown poses a threat not only to grid reliability but also to economic growth. By adopting a more collaborative and long-term approach to transmission planning, the U.S. can ensure a steadier buildout of high-voltage lines and reduce the need for costly and time-consuming upgrades.
What's Next?
The task force recommends that transmission planners incorporate 'optionality' into their long-range planning to accommodate future uncertainties. This includes developing a decision timeline for infrastructure needs and considering grid-enhancing technologies or energy storage solutions to defer or eliminate the need for major upgrades. The report suggests that planners should conduct probabilistic analyses to ensure that new assets are ready in time to meet demand. These steps are intended to create a more flexible and resilient grid that can adapt to evolving energy needs.
