Texas Grid Flags Risks As Data Centers, Crypto Sites Fail Voltage Tests

4 weeks ago
Reuters reports: Several large data centers and crypto facilities planning to connect to the Texas power grid ahead of peak summer demand have failed key reliability tests, raising the risk of power outages just as electricity use hits its seasonal high, according to the state grid operator... Unlike traditional industrial customers, which tend to draw electricity steadily and predictably, data centers are engineered to cut their connection to the grid at the first sign of trouble to protect their equipment and keep services running. That makes them an unpredictable and potentially destabilizing force on grids already under pressure from rising demand. Four groups of unnamed large electricity users, including data centers, abruptly disconnected from the Texas grid during a test of how they would handle routine voltage disturbances, the Electric Reliability Council of Texas (ERCOT) said in a report dated May 21. When large customers abruptly cut their power use, it can knock the grid off balance and trigger wider outages. ERCOT, which manages electricity for most of Texas, said it reviewed about 20 gigawatts of large customers seeking to connect to the system, including eight projects totaling roughly 3.9 gigawatts aiming to start up before July 1. It said it identified four groups of large power users that could each trigger more than 5,000 megawatts of demand tripping under certain fault conditions, based on simulations of transmission system disturbances. Those abrupt drops in demand were equivalent to the electricity consumption of a large city such as Boston.

Police Sued After Imprisoning Innocent Man Placed Near Violent Crime By Flock License Plate Reader

4 weeks 1 day ago
"When Hugo Parra was arrested last year on felony charges, his pleas of innocence fell on deaf ears," reports the Times of San Diego: San Diego police had a description of the Alfa Romeo car he was riding in [but no license plate number] and a witness who identified him during a curbside lineup as the man who brandished a handgun in Golden Hill. They had also checked the city's automatic license plate camera system, run by the private company Flock, and got a "hit," substantiating the claim. The problem, says attorney Alex Coolman, was that Parra was five miles away from Golden Hill at the time of the crime, and the so-called hit from the license plate reader was captured before any police pursuit began. "This Flock hit was obviously the wrong car, as it could not have been in both places simultaneously," said Coolman, who represents Parra and the driver, 23-year-old Ariel Beltran. Despite the signs pointing to it being a different Alfa Romeo, police arrested Beltran and Parra... [An officer had informed dispatch that one of the men "matched the victim's description, other than having a different-colored hooded sweatshirt."] Parra spent nearly one month behind bars, missing Thanksgiving and other special events with his family, before the assault with a firearm and evasion charges were dropped. Parras says he was incarcerated with actual murderers, according to the article, and Parra and Beltran are now preparing to sue the city, seeking $1.5 million each in damages for civil rights violations and negligence. Their claim notes they'd driven past several other Flock cameras which officers could've used to corroborate their story (not to mention location data on their cell phones). Meanwhile, the article also notes that last month the Institute for Justice "identified at least 17 cases in the United States of officers allegedly using Automated License Plate Reader technology to keep tabs on partners, exes, and strangers who had caught their eye..."
