About
Founded in 2016, Heimdall Power is a private headquartered in Oslo, Norway with approximately 200-500 employees specializing in Energy Storage.
Founded in Norway in 2016, Heimdall Power is a global technology company that transforms power grids through advanced sensors and software. The company's flagship product, the Neuron, is a multi-sensor IoT device deployed on overhead transmission and distribution lines to measure real-time environmental and conductor conditions including temperature, wind speed, line sag, and ambient weather. This data feeds proprietary algorithms that calculate thermal line capacity at any given moment, typically revealing 30-40% additional usable capacity compared to static ratings. Heimdall also offers Virtual Neurons, a SaaS solution using ambient data and forecasts. The company serves Transmission System Operators (TSOs) and Distribution System Operators (DSOs) across 16+ countries, with customers including TenneT, Elvia, Austrian Power Grid, Amprion, and leading U.S. utilities. Heimdall's autonomous drone installation system enables safe deployment on live lines up to 450 kV. The company raised $25M in Series B funding in July 2024 and was recognized by TIME as one of the Best Inventions of 2025.

Frequently asked questions
published by the companyWhat is Dynamic Line Rating (DLR)?
Dynamic Line Rating (DLR) is a technology that uses real-time sensor data to determine the actual current-carrying capacity of overhead power lines, rather than relying on fixed static ratings. DLR enables utilities to safely unlock additional transmission capacity without building new infrastructure.
How does Dynamic Line Rating work?
DLR works by deploying sensors on transmission lines that measure real-time environmental and conductor conditions including temperature, wind speed, line sag, and ambient weather. This data feeds into algorithms that calculate the line's true thermal capacity at any given moment, which is typically higher than conservative static ratings.
What is the difference between DLR and AAR?
The biggest difference is the data source. Dynamic Line Rating (DLR) uses real-time sensor data from physical devices on the line to determine actual capacity. Ambient Adjusted Rating (AAR) uses ambient temperature data and weather forecasts with static assumptions. DLR provides superior accuracy, while AAR is less expensive and faster to deploy.
What are the benefits of Dynamic Line Rating?
Key benefits include: unlocking 40%+ additional transmission capacity on average, delaying or avoiding costly infrastructure upgrades, improving grid reliability through real-time monitoring, enabling better integration of renewable energy, and supporting regulatory compliance with mandates like FERC Order 881.
What does DLR stand for?
DLR stands for Dynamic Line Rating. It refers to the practice of calculating the real-time thermal rating of overhead transmission lines based on actual environmental and conductor conditions, as opposed to static or seasonal ratings.
