California's statewide power grid operator is poised to become the first in North America to deploy artificial intelligence to manage outages, MIT Technology Review has learned. At an industry summit in Minneapolis tomorrow, the California Independent System Operator is set to announce a deal to run a pilot program using new AI software called Genie, from the energy-services giant OATI.

California is set to become the first US state to manage power outages with AI

technologyreview.com Alexander C. Kaufman 2025-07-28 23:00:00

In April, the PJM Interconnection—the nation’s largest grid system, spanning 13 states along the densely populated mid-Atlantic and Eastern Seaboard—took a big step toward embracing AI by inking a deal with Google to use its Tapestry software to improve regional planning and speed up grid connections for new power generators. ERCOT, the Texas grid system, is considering adopting technology similar to what CAISO is now set to use, according to a source with knowledge of the plans who requested a

Major US power operator says AI and data center demands are pushing prices up

engadget.com Unknown 2025-08-01 20:00:30

PJM Interconnection (PJM) is the largest power grid operator in the US, serving 65 million customers across the District of Columbia and 13 states, namely Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia. But this summer, some parts of PJM's power grid are expected to use so much electricity that people's bills for the summer are projected to be 20 percent higher than before, according to Reuters. Th

Other Good Backyard Hot Dog Options Look, if you're trying to feed a football team, no little hot dog cooker will do. What you'll want is one of our favorite griddles or grills. No wee steamer can beat a 33-inch Traeger griddle, my favorite griddle of all backyard griddles. There are a couple griddles, however, that seem custom made for hot dogs and buns. This Blackstone Iron Forged Air Fryer Combo comes with two air frying baskets and a third warming basket underneath the griddle. Well, guess

The Download: Google DeepMind’s DNA AI, and heatwaves’ impact on the grid

technologyreview.com Rhiannon Williams 2025-08-24 16:10:00

When scientists first sequenced the human genome in 2003, they revealed the full set of DNA instructions that make a person. But we still didn’t know what all those 3 billion genetic letters actually do. Now Google’s DeepMind division says it’s made a leap in trying to understand the code with AlphaGenome, an AI model that predicts what effects small changes in DNA will have on an array of molecular processes, such as whether a gene’s activity will go up or down.

It’s officially summer, and the grid is stressed

We rely on electricity to keep ourselves comfortable, and more to the point, safe. These are the moments we design the grid for: when need is at its very highest. The key to keeping everything running smoothly during these times might be just a little bit of flexibility. While heat waves happen all over the world, let’s take my local grid as an example.

Puerto Rico's Solar Microgrids Beat Blackout

news.ycombinator.com Julia Tilton 2025-08-24 23:41:16

When power went out across all of Puerto Rico on 16 April, a lot of the lights in the town of Adjuntas stayed on. There, nestled in the mountains on the midwestern side of the island, a combination of experimental microgrids, solar panels, and storage kept power on for many businesses and residents. The rest of the island waited over 24 hours, and in some cases longer, for electricity to be restored. The blackout was the latest in a series of power interruptions that have come to define Puerto

Tesla inks first deal to build China's largest grid-scale battery power plant

cnbc.com Ganesh Rao 2025-09-02 08:48:19

Tesla has inked its first deal to build a grid-scale battery power plant in China amid a strained trading relationship between Beijing and Washington. The U.S. company posted on the Chinese social media service Weibo that the project would be the largest of its kind in China when completed. Utility-scale battery energy storage systems help electricity grids keep supply and demand in balance.

Spanish blackout report: Power plants meant to stabilize voltage didn’t

arstechnica.com Unknown 2025-09-06 12:15:24

The blackout that took down the Iberian grid serving Spain and Portugal in April was the result of a number of smaller interacting problems, according to an investigation by the Spanish government. The report concludes that several steps meant to address a small instability made matters worse, eventually leading to a self-reinforcing cascade where high voltages caused power plants to drop off the grid, thereby increasing the voltage further. Critically, the report suggests that the Spanish grid

The Algebra of an Infinite Grid of Resistors

news.ycombinator.com Unknown 2025-09-11 23:47:48

The Algebra of an Infinite Grid of Resistors In a previous note we discussed the well-known problem of determining the resistance between two nodes of an “infinite” square lattice of resistors. The most common approach is to superimpose two “monopole” solutions, one representing the field for one amp of current entering a given node and flowing “to infinity”, and the other representing the field for one amp of current being withdrawn from a given node flowing in from infinity. If the two nodes

The 5 Best Griddles and Flat-Top Grills of 2025, Tested and Reviewed

wired.com Matthew Korfhage 2025-09-11 20:36:00

Photograph: Matthew Korfhage Griddle seasoning is, quite simply, protection for your griddle. When a thin layer of oil is heated above its smoke point and allowed to cook off atop the griddle and then cool, it forms a polymer that protects the top of the griddle and leads to better cooks. (Some think that griddle seasoning is to help food not stick to the metal. It may or may not add some nonstick properties, but the main purpose is to protect the griddle against rust and other wear.)

Air Conditioners Can Actually Support the Power Grid. Here’s How

As summer arrives, people are turning on air conditioners in most of the U.S. But if you’re like me, you always feel a little guilty about that. Past generations managed without air conditioning – do I really need it? And how bad is it to use all this electricity for cooling in a warming world? If I leave my air conditioner off, I get too hot. But if everyone turns on their air conditioner at the same time, electricity demand spikes, which can force power grid operators to activate some of the

Amazon tapped into an emerging trend this week, one that’s seeing big tech firms buy power from existing nuclear power plants. The tech company will power a chunk of its AWS cloud and AI servers using 1.92 gigawatts of electricity from Talen Energy’s Susquehanna nuclear power plant in Pennsylvania.
