Great River Energy’s implementation of dynamic line rating demonstrated capacity gains, cost savings, and enhanced grid resilience through real-time weather and line condition data.

On the morning of April 28, large parts of Spain, Portugal, and southern France went dark. A massive blackout left millions without power, halting trains mid-track, cutting mobile networks, and rattling the foundation of one of Europe’s most advanced energy grids.

On a cloudy day in mid-July, a crew of technicians carries a shiny metal orb, about the size and weight of a kid’s bowling ball, under a 110-kilovolt transmission line running near Hamburg.

Great River Energy and Heimdall Power report major capacity gains and a projected $3.175 million in avoided congestion costs over five years.

Traditional power line ratings, known as static thermal ratings, are based on conservative worst-case weather assumptions—typically high ambient temperatures, low wind speeds, and maximum solar heating.

“If Apple were to make a product for the power grid, it would probably look something like this,” says Heimdall Power CEO Jørgen Festervoll, referring to his company’s range of Neuron power sensors, also known as Magic Balls.

Tracing back more than a century, modern Artificial Intelligence (AI) has had a fascinating journey, with many critical inflection points along the way.

The energy transition is accelerating—but the infrastructure that delivers electricity isn’t keeping pace. As electric vehicles, heat pumps, and AI-driven data centers push demand to record highs, the grid is being pushed to its limits.

America's power grid is aging. Soon, it may be unable to support the surging demand for electric power over its high-tension powerline infrastructure. While electrical utilities must ultimately upgrade the grid, the companies must manage the existing transmission network more efficiently.

If Steve Jobs designed grid-enhancing technologies (GETs), what would they look like? Heimdall Power chief executive officer Jørgen Festervoll reckons they’d be awfully similar to his company’s Neuron, better known across the power industry as the “magic ball.”

As Southern California Edison responds to lawsuits accusing it of playing a role in a recent scourge of wildfires, grid monitoring is top of mind for electric distribution companies, including a particularly innovative cooperative deploying a new solution that promises to assist with wildfire detection.

On this episode of Alternative Power Plays hosts Alan Seltzer and John Povilaitis sit down with Jørgen Festervoll, CEO of Heimdall Power, a company specializing in advanced monitoring technologies for electric transmission lines.

Heimdall Power has introduced a blueprint to scale the installation of its Neuron sensors to high voltage power lines across the country’s grids.

Where There’s Wind, There’s Often a Surplus of Transmission Capacity In 2023, Minnesota-based power collective Great River Energy completed a two-year study designed to identify the sources of congestion with the highest financial impact on its operations.

Explore the future of the power grid with Jorgen Festervoll, CEO of Heimdall Power. Learn how dynamic line rating technology is optimizing grid capacity, reducing costs, and driving global energy innovation.

In an era of increasing energy demand and aging infrastructure, an international technology company has captured the attention of global investors and the White House with a deceptively simple solution: small, sphere-shaped sensors nicknamed "Magic Balls."

Heimdall Power’s unique combination of cloud-based software and hardware can boost power grid efficiency by up to 40 percent. The technology is powered by reliable Azure services.

Aging high-voltage transmission lines are a bottleneck in the power grid today, but what if a simple tweak could increase their capacity by up to 40 percent? That’s what Great River Energy in Minnesota is now looking into.

The country’s aging power grid, built over the past 100 years, is about to leap into the 21st century as the Biden administration scrambles to meet a coming burst of new power demand.

Norwegian company Heimdall Power has developed an industrial Internet of Things device called Neuron, which monitors high-voltage power lines and optimises power grids.

The Minnesota legislature has passed a bill adding grid enhancing technologies (GETs) to the state’s transmission planning process. In terms of the bill, utilities owning more than 1,200km of transmission lines are required to report on highly congested areas and to evaluate the use of GETs on these, along with presenting a proposed installation plan.

Technology that will increase the flow of energy in American power lines and reduce prices for consumers is coming to the United States. According to reporting in Inside Climate News, grid-enhancing technology that could increase capacity by up to 42.8% is on its way.

The rise of artificial-intelligence (AI) data centres, with their insatiable hunger for electricity, is asking an awful lot of the world’s utilities and grid operators.

A sensor about the size of a bowling ball can measure the real-time temperature of a transmission line. With this information, the operator can safely increase the level of power flowing through the line.

Norwegian startup Heimdall Power is working with Minnesota’s Great River Energy to squeeze more electricity out of the utility’s power lines with AI-enabled temperature and weather monitoring.
