As of March 25, 2025, the US electricity grid faces mounting pressure from surging demand—driven by data centers, EVs, and industrial electrification—while aging transmission lines operate far below their true capacity. Grid Enhancing Technologies (GETs) offer a proven, cost-effective path to unlock up to 10–30% more capacity from existing infrastructure without building new lines. This article explores how GETs work, their market uptake, and the latest regulatory push from FERC.
Grid Enhancing Technologies encompass a suite of hardware and software solutions that give operators real-time visibility into transmission line conditions. Instead of relying on static, worst-case assumptions, GETs monitor temperature, wind, solar radiation, and line sag to safely push more power through existing corridors. Key categories include Dynamic Line Rating (DLR), advanced power flow controllers, and topology optimization software.
The US transmission system was largely built in the 1960s and 1970s. Today, electricity demand is projected to grow 15% by 2030, according to a 2024 DOE report. Simultaneously, renewable energy projects—often sited far from load centers—face interconnection delays averaging five years. GETs can cut those delays by enabling existing lines to carry more clean power.
Key drivers:
DLR systems use sensors and weather data to calculate real-time line capacity. During windy or cool conditions, lines can carry 20–40% more current than static ratings allow. Utilities like National Grid and Xcel Energy have deployed DLR on congested corridors, reporting 10–15% capacity gains.
Devices such as series compensation and phase-shifting transformers direct electricity away from overloaded paths onto underutilized lines. This reduces congestion and allows higher renewable penetration. PJM Interconnection, the largest US grid operator, has begun integrating power flow controls into its planning.
AI-driven tools analyze thousands of switch configurations to recommend the most efficient network state. The US Department of Energy’s GRID Lab has shown that topology optimization can reduce curtailment of renewables by 20% without compromising reliability.
In 2024, the Federal Energy Regulatory Commission (FERC) issued Order 1920, requiring regional transmission planners to consider GETs in their long-term planning processes. This marks a shift from traditional “build more lines” thinking. The order also mandates cost-benefit analysis that includes the value of deferred construction and reduced congestion.
In addition, the 2025 Bipartisan Infrastructure Law has allocated $5 billion for grid resilience and modernization, with a portion specifically earmarked for GETs demonstration projects.
Despite clear advantages, GETs face adoption hurdles:
GETs rely on a digital ecosystem: IoT sensors, cloud analytics, and digital twins. Companies like GE Vernova and Siemens are developing predictive models that can forecast line capacity 24–48 hours ahead, enabling operators to optimize scheduling and storage.
According to a 2025 report by Precedence Research, the global GETs market is expected to grow from $1.2 billion in 2024 to $3.8 billion by 2032, with North America holding the largest share. Utilities are increasingly bundling GETs with battery storage and demand response.
The US does not need to build its way out of the grid crisis—it can smarten the grid it already has. Grid Enhancing Technologies offer a low-cost, high-impact solution that aligns with regulatory mandates, decarbonization goals, and the need for resilience. With FERC leading the way and technology maturing rapidly, 2025 is shaping up to be the year GETs go mainstream.
