160. How Grid Enhancing Technologies Are Expanding Electric Power Transmission System Capabilities The POWER Podcast

It’s no secret that power grids around the world need to expand to accommodate more renewable energy and the so-called “electrification of everything.” The latter, of course, refers to the growing trend of using electricity to power various sectors and applications that have traditionally relied on fossil fuels, such as natural gas or petroleum-based products. The electrification of everything includes the push toward electric vehicles; the transition from fossil fuel–based heating and cooling systems to electric alternatives, as well as the adoption of electric appliances; and the shift to more electric motors, furnaces, and other electric-powered equipment in manufacturing processes. Add to that the expected power needed to supply data centers and the growth of artificial intelligence-related computing, and current estimates of 50% load growth by 2050 could be vastly understated.
Yet, getting new transmission lines planned, approved, and constructed is a daunting task, often taking a decade or longer to complete. So, how can the world more quickly add transmission capacity to the system without investing enormous time and money in the process? The answer: grid enhancing technologies, or GETs.
“GETs are exciting to us because they are technologies that help us unlock quickly the additional headroom or additional capability of the grid to carry energy across the system,” Alexina Jackson, vice president of Strategic Development with AES Corp., said as a guest on The POWER Podcast. “This is something that is very important, because today, we are not making the fullest use of the electricity system as it’s built.”
The system is operated below its maximum capacity for very good reasons, specifically, to maintain reliability, but by implementing GETs, it can be operated closer to its true limits without risk of failure. “Once we have these technologies, such as dynamic line rating, which helps us visualize the dynamic and full headroom of the electrical grid, and then technologies like storage as transmission, advanced power flow control, topology optimization—they all allow us to operate the grid in its dynamic capability. By doing both these things—visualization and operation dynamically—we’re able to start making fuller use of that carrying capacity for energy, which will allow us to add additional energy more quickly, serve our customer needs more efficiently, and ultimately decarbonize faster,” Jackson said.
