New Legislation for Grid Enhancements
The Minnesota legislature has passed a bill requiring utilities with over 1200 km of transmission lines to report highly congested areas and evaluate the use of Grid Enhancing Technologies (GETs). Utilities must identify locations with 168 hours or more of congestion or the ten most costly congestion spots over the past three years and propose installation plans.
Improved Transparency
The law mandates that utilities explain their current line rating methodology, enhancing transparency. The state public utilities commission will maintain a list of certified high voltage transmission line and GETs projects.
Great River Energy’s Deployment
Great River Energy, a Minnesota-based utility, is expanding its use of Heimdall Power’s Neuron dynamic line rating sensors. Following a pilot, over 40 sensors will be deployed across Minnesota, Wisconsin, and North Dakota. In April, the first of these sensors was installed on a live 115 kV line using an autonomous drone system, a technique pioneered in Europe.
