Heimdall Power digitises and upgrades the power grid

Around the world, the electrical grid is facing pressing challenges such as growing electrification, a huge increase in variable renewable energy production and more decentralised energy production. Meanwhile, more extreme weather events also threaten the grid’s stability and capacity.

Without direct, real-time data from physical infrastructure such as power lines, it is difficult to achieve adequate grid flexibility, efficiency and reliability, and avoid electricity loss and power outages.

Using IoT technology, Heimdall Power has developed the Neuron™, a unique overhead line sensor for monitoring high-voltage power lines. The sensors are installed on the power lines and send a data stream of information to the Heimdall Cloud, which then digitises, analyses and regulates the flow of power.

The applications can detect and locate faults instantly, and even predict faults in progress or fluctuations in capacity due to vibrations, changes in weather or build-up of ice. Grid operators receive real-time alerts about power surges and failures, enabling them to initiate maintenance procedures quickly.

The solution enables thermal management of power lines, which increases and optimises the capacity of the lines, preventing the build-up of “stranded” energy from wind farms and other renewable sources.

An efficient electrical grid is vital to utilising energy in the best possible way, effectively reducing greenhouse gas emissions in the process.

By collecting and analysing digital data, Heimdall Power’s sensors and software help electric utilities to increase power line capacity, improve planning, make grid operations more cost-effective, reduce downtime and electricity losses, and extend the lifetime of the existing grid infrastructure.

The solution can be installed on fully energised power lines with drones in a matter of seconds, which means that no outages are needed for the technology to be deployed. Further, it does not require an external power source and can be used globally with minimal maintenance and adjustments.

The International Energy Agency (IEA) estimates that USD 7.2 trillion will be invested in transmission and distribution grids during the period 2012–2035.

Heimdall Power’s target market is all power lines above 7 kV. These lines are standardised globally, and Germany alone has 685 000 km of them.

In 2025 Heimdall Power has installed sensors for 50 utilities in 19 countries around the globe, and recently opened a new North American HQ in Charlotte, North Carolina.
