The US energy landscape is undergoing a dramatic transformation, driven by rapid technological developments and surging demand from emerging sectors such as data centres, cryptocurrency mining, electric vehicles, and industrial electrification. These trends are reshaping how electricity is generated, consumed, and delivered. As a result, experts estimate that the country will need to double or triple its transmission capacity in the coming decades. In response, the Federal Energy Regulatory Commission (FERC) introduced Order 1920, along with clarifications Order 1920-A and 1920-B, as a landmark reform in long-term regional transmission planning. A new report published by the American Council on Renewable Energy (ACORE) in April 2025, and prepared by the Brattle Group and Grid Strategies, explores the significant opportunities unlocked by FERC Orders 1920 and 1920-A. The report, titled “Incorporating GETs and HPCs Into Transmission Planning Under FERC Order 1920”.
According to the report, FERC Orders 1920 and 1920-A provide a foundation for more holistic and cost-effective transmission solutions by explicitly supporting the use of alternative transmission technologies (ATTs), such as dynamic line ratings (DLR), advanced power flow control, transmission switching, and high-performance conductors (HPCs), along with other grid-enhancing technologies (GETs). These technologies are cheaper and faster to deploy than traditional wires-based upgrades, often reversible, and deliver multiple system benefits. ACORE’s review of 25 case studies revealed that ATTs consistently provided at least one of the seven benefits required under Order 1920, such as reduced energy losses, increased system reliability, and better response to extreme weather and unexpected conditions. The report identifies four main barriers to widespread ATT deployment: undervaluation of their benefits, misaligned incentives, outdated planning methods, and limited analytical capacity among planners.
The report concludes that the updated provisions in Order 1920-A — particularly the enhanced role of state entities in shaping scenario development and cost allocation — present a critical opportunity for advancing these technologies. The relevant state entities now have the authority to advocate for broader benefit considerations, including deployment speed and optionality, which often favor ATTs. Additionally, the relevant state entities and transmission customers can voluntarily fund certain transmission projects. As transmission providers are required to model at least three “plausible and diverse” future scenarios and consider seven specific benefits in evaluating long-term transmission needs, these policy updates collectively position ATTs and GETs as practical, effective components in the nation’s evolving transmission strategy. FERC’s framework provides a strong foundation, but proactive efforts from all stakeholders will be essential to overcome barriers, realise the full potential of all available technologies, and accelerate the industry transition.
