AUSTIN, Texas, June 10, 2026 — Gridraven, a grid software company developing software-based dynamic line rating (DLR), a type of grid-enhancing technology (GET), today released its Gridraven PJM congestion cost study and launched the public Gridraven Congestion Tracker, a new tool designed to show where transmission bottlenecks are driving electricity costs across PJM Interconnection, the largest power market in North America.
“Congestion raises our bills by making electricity more expensive,” said Georg Rute, CEO of Gridraven. “The lack of sufficient transmission capacity is an increasing challenge that prevents the lowest-cost power from reaching us.”
Key findings from the Gridraven PJM congestion cost study
Between March 30 and May 1, 2026:
- $564 million in total PJM congestion costs
- $75 million in congestion costs tied to 42 monitored constraints
- More than 14% average untapped transmission capacity identified on those constrained lines
- $49 million in estimated monthly congestion savings across PJM if that additional capacity were unlocked
- Nearly $2 million in congestion costs on one transmission line in 24 hours
Gridraven’s PJM congestion cost study is based on publicly available PJM market data combined with Gridraven’s software-based DLR and the new Gridraven Congestion Tracker.
The findings suggest that relatively modest increases in available transmission capacity could create outsized economic savings in highly constrained parts of the PJM grid.
One transmission line analyzed in the study — the Graceton–Manor 230 kV line between southeastern Pennsylvania and northern Maryland — generated nearly $2 million in congestion costs in a single 24-hour period. Gridraven found that software-based DLR could have reduced those costs by roughly 70% by increasing available transmission capacity during the event.
“Small increases in transmission capacity can create disproportionately large economic savings,” said Rute. “By making the most of our existing grid it’s possible to reduce bills in the short term, while we build more transmission.”
Why this matters
Grid congestion happens when lower-cost electricity cannot reach demand centers because transmission lines hit operating limits. When that happens, more expensive local power is often dispatched instead, increasing system-wide electricity costs.
As electricity demand rises from AI data centers, industrial growth and electrification, transmission bottlenecks are becoming more economically significant across U.S. power markets.
Gridraven’s software-based DLR is part of a broader category of grid-enhancing technologies (GETs), also known in some regulatory discussions as advanced transmission technologies (ATTs), which utilities and regulators are increasingly evaluating as faster ways to increase grid capacity without waiting years for new transmission infrastructure.
Some transmission ratings still rely on conservative assumptions and do not fully account for actual wind conditions that can allow power lines to safely carry more electricity. Gridraven’s software-based DLR uses weather forecasting, terrain modeling and machine learning to estimate how much additional power specific lines can safely carry under real-world conditions.
That additional transmission headroom can help lower-cost electricity, including renewable power, reach demand centers more efficiently.
The Gridraven Congestion Tracker is a public tool that shows where transmission bottlenecks are driving electricity costs across PJM. The company says additional lines are being added and monitored on an ongoing basis through the Gridraven Congestion Tracker.
Gridraven’s software-based DLR technology is already operating on transmission networks in Europe, including full-scale deployments with Fingrid in Finland and Elering in Estonia, each spanning approximately 5,000 km of transmission lines. The company plans to launch its first U.S.project later this year.
Frequently Asked Questions
What is the Gridraven PJM congestion cost study?
The Gridraven PJM congestion cost study analyzes publicly available PJM market data to estimate how transmission bottlenecks contribute to congestion costs and how software-based dynamic line rating could reduce those costs.
What is the Gridraven Congestion Tracker?
The Gridraven Congestion Tracker is a public tool that shows where transmission bottlenecks are driving electricity costs across PJM and how much of those costs could be reduced with Gridraven’s software-only DLR.
What is software-based dynamic line rating (DLR)?
Software-based dynamic line rating uses weather forecasting, terrain modeling and machine learning to predict how much electricity transmission lines can safely carry under real-world conditions.
What are grid-enhancing technologies (GETs)?
Grid-enhancing technologies (GETs) are technologies designed to increase the efficiency and capacity of existing transmission infrastructure. Software-based dynamic line rating is one type of GET.
Why does grid congestion matter?
Grid congestion can prevent lower-cost electricity from reaching demand centers, forcing more expensive generation onto the system and increasing electricity costs.
