Data center tweaks could unlock 76 GW of new power capacity in the US

Published

on


Tech companies, data center developers, and power utilities have been panicking over the prospect of runaway demand for electricity in the U.S. in the face of unprecedented growth in AI.

Amidst all the hand wringing, a new paper published this week suggests the situation might not be so dire if data center operators and other heavy electricity users curtail their use ever so slightly.

By limiting power drawn from the grid to 90% of the maximum for a couple hours at a time — for a total of about a day per year — new users could unlock 76 gigawatts of capacity in the United States. That’s more than all data centers use globally, according to Goldman Sachs. To put that number into perspective, it’s about 10% of peak demand in the U.S.

If data centers were to curtail their use more, they could unlock progressively more capacity.

Such programs aren’t exactly new. 

For decades, utilities have encouraged big electricity users like shopping malls, universities, and factories to curtail their use when demand peaks, like on hot summer days. Those users might turn down the air conditioning or turn off thirsty machines for a few hours, and in return, the utility gives them a credit on their bill.

Data centers have largely sat on the sidelines, instead opting to maintain uptime and performance levels for their customers. The study argues that data centers could be ideal demand-response participants because they have the potential to be flexible.

There are a few ways that data centers can trim their power use, the study says. One is temporal flexibility, or shifting computing tasks to times of lower demand. AI model training, for example, could easily be rescheduled to accommodate a brief curtailment. 

Another is spatial flexibility, where companies shift their computational tasks to other regions that aren’t experiencing high demand. Even with data centers, operators can consolidate loads and shut down a portion of their servers.

And if tasks are mission critical and can’t be delayed or shifted, data center operators can always turn to alternative power sources to make up for any curtailment. Batteries are ideally suited for this since even modestly sized installations can provide several hours of power almost instantaneously. 

Some companies have already participated in ad hoc versions of these. 

Google has used its carbon-aware computing platform, originally developed to trim emissions, to enable demand response. Enel X has worked with data centers to tap into the batteries in their uninterruptible power supplies (UPS) to stabilize the grid. And PG&E is offering to connect data centers to the grid quicker if operators agree to participate in a demand response program.

These tweaks won’t completely eliminate the need for new sources of power. But they might turn a potentially catastrophic situation — in which half of all new AI servers are underpowered — into one that’s more easily solved.

Pattaya adapts to welcoming Indians and Westerners, while hoping for Chinese tourism’s return

PATTAYA, Thailand — As Thailand continues promoting its “Welcome All” tourism revival campaign, some foreign visitors in Pattaya are quietly wondering: What happens if the Chinese return — and what if they don’t?

Strolling along Jomtien Beach or lounging in bars on Soi Buakhao, it’s not uncommon to hear debates about whether Pattaya’s fortunes still hinge on mass Chinese tourism, or if the city has already moved on.

“They’ll be back,” said one longtime European retiree. “Just as soon as they realize there’s nothing to do in Vietnam or elsewhere.”

But not everyone agrees. “No one really cares about Chinese tourists,” one tourist bluntly claimed. “They’ve never been big spenders and will never be. Get more Westerners — they’re the real big spenders.”

It’s a sentiment echoed by others who say Western retirees are the real financial engine behind Pattaya’s nightlife and hospitality industries. “Retirees can spend 10,000 baht a night,” said a bar owner. “Chinese groups come, take pictures, and maybe spend much less than that as per person.”

However, some locals are less certain. “Indians have taken over,” one Pattaya shopkeeper shrugged. “Chinese aren’t too keen on coming here now.”

But another argued, “Maybe you haven’t seen the Chinese eat and spend — they do it easily here, especially in restaurants and shopping malls.”

Yet despite the critiques, businesses haven’t given up on the return of Chinese mass tourism. Many remember the packed tour buses and back-to-back bookings before the pandemic. “Obviously, you haven’t seen nothing yet,” said a Thai tour guide, optimistic about a comeback.

The Tourism Authority of Thailand (TAT) is working hard, busting their whole office to make the return happen sooner or later — arranging chartered flights, fast lanes at airports, elevated safety measures, and AI-aided security to welcome visitors back smoothly and confidently.

Others remain skeptical — comparing hopes for the Chinese revival to the long-dashed expectations of Japanese tourist rebounds after the 1991 economic crash. “They are the same people who awaited the revival in the number of Japanese tourists,” one expat remarked dryly.

For now, Pattaya waits — balancing its hopes on a mix of returning Chinese visitors, Indian family tours, and Western retirees. One thing is clear: no one group will carry the city forward alone.

Typhoon Wipha causes travel chaos as hundreds of flights canceled in Hong Kong

Published

on


HONG KONG, July 20 — Hong Kong issued its third-highest tropical cyclone warning in the early hours of Sunday as Typhoon Wipha drew nearer, with authorities cancelling classes and grounding hundreds of flights.

Wipha was located around 280 kilometres southeast of Hong Kong as of midnight (1600 GMT), according to Hong Kong’s weather observatory.

The observatory has hoisted the T8 warning signal, meaning that “winds with mean speeds of 63 kilometres per hour or more are expected”.

The storm was expected to keep intensifying, moving across the northern part of the South China Sea and edging closer to the coast of China’s Guangdong province.

“There will be frequent heavy squally showers and thunderstorms over the region. Seas will be high with swells,” the observatory added.

China’s Hainan and Guangdong provinces were also put on high alert, state news agency Xinhua reported Saturday.

More than 250 flights servicing Hong Kong had been cancelled as of late Saturday, according to the website of the city’s international airport.

Hong Kong’s Airport Authority asked travellers to prepare for “significant flight cancellations or delays” and said that no passenger flights are expected to depart the city before Sunday noon.

Authorities suspended Sunday’s classes at all day schools and daycare centres.

Bus services are expected to be halted until midday Sunday.

Wipha brought heavy rains and flooding to the Philippines and two people have been reported missing, according to the country’s National Disaster Risk Reduction and Management Council. — AFP
