In late 2023, Great River Energy installed four of Heimdall Power’s Neurons (known colloquially as “magic balls”), sphere-shaped sensors that sit on live, high-voltage power lines to collect and measure real-time data on current, line angle, temperature and weather conditions.

Minnesota-based Great River Energy, a Midwest power cooperative, announced it has expanded its power line capacity by an average of 25%, due to its use of Heimdall Power’s sensors.

In late 2023, Great River Energy installed four of Heimdall Power’s Neurons (known colloquially as “magic balls”), sphere-shaped sensors that sit on live, high-voltage power lines to collect and measure real-time data on current, line angle, temperature and weather conditions. Having originally set out to determine and resolve the causes of congestion on one of its key lines, Great River Energy says its work with Heimdall Power has achieved as much as a 42.8% increase in electricity capacity on a single line. In the process, it has set the foundation to comply with upcoming dynamic line rating regulations.

Demand for electricity is expected to nearly double over the next 30 years, with many in the industry choosing to build more power lines and facilities to meet this demand, which is often costly and time-consuming. Additionally, the upcoming 2025 Federal Energy Regulation requirements (FERC Order 881) for Ambient Adjusted Ratings (AAR) are adding more urgency for grid operators to address existing infrastructure, by requiring dynamic transmission line ratings that are adjusted at least hourly.
