It is no wonder that utilities are having trouble keeping up with the surging demand for electricity to power AI data centers. A recent International Energy Agency (IEA) report forecasts that data centers’ total electricity consumption could reach more than 1,000 terawatt-hours(TWh) in 2026, demand roughly equivalent to the electricity consumption of Japan. As AI gets incorporated into software programming in various sectors, demand is expected to spike even more. The study forecasts that search engine sites like Google could witness a tenfold increase in electricity demand when AI is fully implemented on its platform. When comparing the average electricity demand of a typical Google search (0.3 Wh of electricity) to OpenAI’s ChatGPT (2.9 Wh per request), and considering 9 billion searches daily, this would require almost 10 TWh of additional electricity in a year. “Updated regulations and technological improvements, including on efficiency, will be crucial to moderate the surge in energy consumption from data centers,” says the report. That is where Heimdall Power comes in. The Norwegian scale-up has developed an eight pound “magic ball”, a sensor the size of a bowling ball that once fastened to live power lines by drones, can increase existing power line capacity by 30% to 40%. How is that possible? Power lines get hotter as flow increases. If they get too hot, they shut down. Without accurate sensors a power company sets limits on the flow of power on a seasonal basis rather than in response to real-time conditions, which can lead to a lot of unused capacity. “Think about the temperature on the line as being the speed limit,” CEO Jørgen Festervoll, said in an interview with The Innovator. “Without accurate information utilities are driving without a speedometer so they drive conservatively. Our technology allows them to get as close to the speed limit as possible.” That’s important because as the world moves away from fossil fuels more electricity is needed not just for AI but for clean energy. “Often these projects are told that the grid is full and to come back in seven to 10 years, the time to build a new line,” says Festervoll. “That is not good for the economy, and it is not good for the climate. Society is saying we want AI, we want Cloud services, we want electric vehicles, but you can’t have all of that and renewable energy unless there is enough capacity on the grid.” |
