Lydian's Faraday battery is in commercial operation at 600 MWh beside a 525 MW solar plant - the magazine headline prints 150 MW, four hours times 150 is 600, the contract is with PacifiCorp, and the pages do not put the box on Meta's meter
On 11 November 2026 Renewable Energy Magazine said Lydian's Faraday battery in Utah County had reached commercial operation, with operations started on 18 September and no year printed on that date. The body prints 600 MWh under a long-term storage agreement with PacifiCorp, a four-hour lithium-iron-phosphate box, and a site of about eight acres next to the 525 MW Faraday solar plant, sharing that plant's substation. The headline prints 150 MW. The body does not. Energy-Storage.News the same day prints 150 MW / 600 MWh, a Schedule 34 line, an announcement on 10 November, and about US$9 million of expected property tax. It says a February description put phase 1 at 150 MW / 733 MWh, and that US$689 million of financing covered this battery and two solar projects. Neither November page puts the box on Meta's meter.
A data-centre operator can read a battery that supports the site. The November pages put the contract on the utility. They do not put the box on the building's meter.
Renewable Energy Magazine, dated 11 November 2026, says Lydian Energy's Faraday battery in Utah County has reached commercial operation. It says operations started on 18 September. The page does not print a year on that date. It says the project supports Meta's Eagle Mountain data centre and grid reliability in Utah. The body calls the box standalone, four-hour, and lithium-iron-phosphate. It delivers 600 MWh of contracted storage to PacifiCorp under a long-term energy storage agreement. The site is about eight acres, next to the 525 MW Faraday solar plant, and it shares that plant's substation and interconnection. Mobilisation to commercial operation took about 10 months. A company line on the page says a wildfire threatened the area in June and the project stayed on track. The page does not print a dollar cost for the fire or for the box.
The magazine headline prints 150 MW. The body does not print 150 MW. Four hours at 150 MW is 600 MWh, our arithmetic. Energy-Storage.News, also 11 November 2026, prints 150 MW / 600 MWh in the body and calls the duration four hours. 600 divided by 150 is 4, our arithmetic. The two pages agree on 600 MWh. Only one of them prints 150 MW in the body.
Energy-Storage.News says the project was announced on 10 November and is contracted under a Schedule 34 agreement to support Meta's Eagle Mountain data centre. It says the box delivers its contracted storage to PacifiCorp under a long-term energy storage agreement. The magazine page does not print "Schedule 34". Neither page prints the years on the agreement, a dollar rate, or a cents figure. Neither page says the battery sits on Meta's premises. "Support" is the verb. The customer on the contract, as these pages print it, is the utility.
The solar plant next door is 525 MW. The pages say the battery shares its substation. They also call the battery standalone. They do not say the box charges only from that solar plant. A battery holds what the grid or a plant puts in. It does not make electricity. These pages do not print a fuel saving or a generator the battery stands in for.
Energy-Storage.News says the project is expected to generate around US$9 million in property tax over its life. The magazine page does not print that figure. Property tax is not a power price. The same Energy-Storage.News page says a February 2026 financing was US$689 million for Faraday and two solar projects, AC Ranch 1 in New Mexico and Yellow Viking in Texas. That sum is not the price of the 600 MWh. The page says the February description of phase 1 was 150 MW / 733 MWh. The November pages print 600 MWh. 733 minus 600 is 133 MWh, our arithmetic. This note does not open the February release, and it does not explain the gap.
A second phase, Faraday 2, would add up to 375 MW / 1,500 MWh, with a targeted in-service date in the fourth quarter of 2028. Both November pages print those figures. 1,500 divided by 375 is 4 hours, our arithmetic. "Up to" and "targeted" are the pages' words. The second box is not in service on these pages.
Analogy: the battery is a tank on the utility side of the wire, next to a solar field. Meta's name is on the support line. The tank is not on the data centre's meter. 600 MWh is the volume the November pages print. US$689 million is a financing pile that includes other plants. It is not the price of the tank.
Good: Two 11 November pages, 600 MWh kept as 600 MWh, 150 MW kept on the headline and on Energy-Storage.News, four hours checked as 600 divided by 150, and the contract kept with PacifiCorp.
Bad: No year on 18 September. No dollar rate. No term of years. No statement that the box charges from the 525 MW plant. The US$9 million is expected property tax on one page only. The 733 MWh is that page's account of a February description. This note did not open the February release.
Ugly: Calling 600 MWh a box on Meta's meter. Calling US$689 million the price of the battery. Treating 733 MWh as the November size. Treating phase 2 as switched on. Calling the battery a generator. Inventing a cents rate.
Soft next step: write the operating box as 600 MWh on a PacifiCorp contract, leave 150 MW on the pages that print it, and leave Meta's meter blank.
