This summer has already produced three answers to questions the data center industry would have preferred to leave theoretical.<\/p>\n
In May, the PJM Interconnection \u2014 the grid operator serving data center-dense northern Virginia \u2014 received emergency authorization from the Energy Department to curtail power to data centers due to \u201catypically hot mid-May weather conditions.\u201d In France, temperatures of 44.3C forced nuclear plants to shut down \u2014 the same plants Macron called the \u201cheart\u201d of France\u2019s AI ambitions. And on Monday, Zurich Insurance disclosed that severe weather is now the leading cause of loss in its U.S. data center portfolio.<\/p>\n
The questions: Can data centers actually hold up in a warming world? And has the industry priced that in?<\/p>\n
Data centers are having a massive year. So far in 2026, the world\u2019s largest companies operating data centers have committed at least $750 billion to the sector, compared to $450 billion last year, the early stages of more than $3 trillion in forecasted capital investments over the next five years, according to Moody\u2019s.<\/p>\n
That spending is now running directly into a stress test nobody scheduled.<\/p>\n
A study published earlier this month by climate analytics firm First Street found that 79% of global data center capacity faces high risks from climate and weather elements, including from heatwaves and flash flooding. These hazards can disrupt operations, lead to prolonged downtimes, and raise insurance costs, the study found.<\/p>\n
Because the U.S. contains some of the world\u2019s largest and fastest-growing data center hubs, its risk profile is sharper than most. Parts of the country that are seeing a surge in new data center construction as well as a rise in costly extreme weather such as flooding or drought include the Carolinas and Virginia, respectively ranked 5th and 6th in climate risk among the 97 global data center markets surveyed by First Street. Of 809 planned U.S. data centers, 517 are located in areas under drought warnings in the past year, according to an analysis by the Guardian.<\/p>\n
Texas, home to at least 248 planned data center projects, illustrates the tension: the state\u2019s cheap land and sparse population make it attractive to developers, but last year\u2019s historic floods forced sites onto backup diesel generators and cut off repair crews \u2014 a preview of what hotter, wetter summers could mean for the country\u2019s fastest-growing data center market.<\/p>\n
High heat and drought can be just as dangerous. Data centers require extensive cooling equipment to make sure the servers they hold don\u2019t overheat, but high temperatures can cause these cooling systems to fail faster. Data centers operating in these conditions also tend to pay more for energy and water, because they need to consume more to cool their systems down.\u00a0<\/p>\n
It\u2019s a similar story in other countries. Out of 8,808 data centers worldwide that were operational late last year, almost 7,000 were located in areas with typical temperatures outside what is considered the optimal range for servers to operate in, according to an analysis by Rest of World<\/em>.\u00a0<\/p>\n The French shutdowns underscore a specific vulnerability: data centers don\u2019t just need cooling \u2014 they need the power grid to hold up while they\u2019re doing it, and that grid has its own heat problem.<\/p>\n In the U.S., grid operators have already warned companies managing data centers to be prepared for unexpected changes to service if weather conditions demand. Last month, the PJM Interconnection\u2014which serves data center-dense northern Virginia\u2014announced it had received authorization from the Energy Department to curtail power services to data centers and other large loads, due to \u201catypically hot mid-May weather conditions.\u201d Texas Gov. Greg Abbott has also requested the state\u2019s independent grid operator to demand operational limits for data centers it provides power to, citing affordability concerns.<\/p>\n As grids juggle data centers\u2019 rising power needs with the demands of high summer temperatures, insurers are starting to take note.\u00a0<\/p>\n Zurich, a Swiss insurance provider, now counts severe weather as the leading cause of loss in its U.S. data center risk portfolio, CNBC <\/em>reported on Monday. Those losses and all the ways extreme weather can drain performance, including productivity loss, infrastructure damages, and higher operational costs, could add up to a $3.3 trillion bill for data centers by 2055, according to an analysis last year by researchers at the World Economic Forum. Climate-related costs, primarily driven by high heat, would result in losses worth nearly 10% of total data center asset value, the researchers found.<\/p>\n<\/div>\n #summers #heat #live #stress #test #data #centers #heres #revealing #real #time<\/p>\n","protected":false},"excerpt":{"rendered":" This summer has already produced three answers to questions the data center industry would have preferred to leave theoretical.
