THE SHORT VERSION
- Some AI data centers are making their own electricity with jet engines pulled from retired aircraft and rebuilt to burn natural gas, TechCrunch reported, citing the New York Times.TechCrunch 援引《纽约时报》报道，一些 AI 数据中心把退役飞机上的喷气发动机改装成烧天然气的机组，自行发电。
- The draw is speed: a jet-powered unit can have a data center running in about 24 months, while a 100-megawatt grid connection in Northern Virginia takes roughly seven years, according to the International Energy Agency.吸引力在于速度：喷气发动机供电约 24 个月就能让数据中心运转，而按国际能源署数据，北弗吉尼亚接入 100 兆瓦约需七年。
- xAI installed eight converted turbines in Mississippi for its Colossus 2 campus, and the trade-offs are real: the engines are less efficient and pollute more than turbines built for conventional gas plants.xAI 已在密西西比为 Colossus 2 安装八台改装机组，代价同样真实：它们比常规燃气轮机效率更低、污染更大。
Aircraft engines behind the fence围栏之内的航空发动机
Stuck in years-long queues for grid connections and new turbines, some AI data centers are making their own electricity with converted jet engines, TechCrunch reported, citing the New York Times. The engines, pulled from retired aircraft and rebuilt to burn natural gas, are not anyone's idea of a permanent power plant, but they are another sign of how far power supply has fallen behind the AI buildout.在并网和采购新燃气轮机都要排队数年的情况下，一些 AI 数据中心开始用改装喷气发动机自行发电，TechCrunch 援引《纽约时报》报道。这些发动机取自退役飞机，被重造为燃烧天然气的机组，没人认为它们是永久电厂，但它们说明供电已经落后 AI 建设多远，也说明运营商愿意为此付出什么代价。
TechCrunch reporter Aditya Mehta described the trade plainly: for developers stuck in those lines, the main draw is how quickly the units can be running. Rystad Energy analyst Audun Martinsen told the Times that with jet-powered units a data center can be running in 24 months, against roughly seven years for a comparable grid connection in Northern Virginia. Speed, not efficiency, is the product.TechCrunch 记者 Aditya Mehta 把取舍讲得很直白：对困在队列里的开发商来说，最大吸引力是机组能多快运转起来。Rystad Energy 分析师 Audun Martinsen 对《纽约时报》说，用喷气发动机供电，数据中心 24 个月就能运行；而在北弗吉尼亚做同等并网，按国际能源署数据约需七年。真正的产品是速度，不是效率。
Twenty-four months against seven years24 个月对 7 年
The comparison is the story. Hooking up 100 megawatts to the grid in Northern Virginia takes about seven years, according to the International Energy Agency, a figure TechCrunch used to frame the gap. A converted engine does not wait in an interconnection queue; it burns gas on site and starts producing power within months of delivery. The building can be standing before the utility has finished studying the request.对比本身就是故事。据国际能源署，在北弗吉尼亚接入 100 兆瓦电网容量约需七年，TechCrunch 用这个数字框定差距。改装机组不必等互联队列，它在现场烧气，交付后几个月内就能发电。往往在公用事业公司还在研究申请时，机房已经盖好了。
The queue is not only about wires. Bloomberg reported that demand for natural gas turbines is outpacing manufacturing capacity, with the chief executive officer of Mitsubishi Power's Asia Pacific arm saying deliveries now land around 2031. That is the timeline data centers are trying to escape, and it applies to the equipment they would otherwise buy. Capital cannot buy a machine nobody is building yet.排队不只发生在电线上。彭博社报道，天然气轮机需求正超过制造产能，三菱动力亚太区首席执行官称交付时间已在 2031 年前后。这正是数据中心想逃离的时间线，而它针对的恰是它们本要采购的设备。钱买不到一台还没人开始造的机器，于是它们转头去买退役飞机上的二手发动机。
Eight turbines in Mississippi密西西比的八台机组
Elon Musk's xAI is among the companies already using the engines, having installed eight converted jet-engine turbines in Mississippi to help power its Colossus 2 data center in Memphis, the Times reported, citing state permits and satellite imagery. The units come from ProEnergy, which rebuilds a GE engine commonly found on Boeing jets. These are engines that once carried passengers.马斯克的 xAI 已经在用这类设备。《纽约时报》援引州许可文件与卫星图像报道，该公司在密西西比安装了八台改装喷气发动机机组，为孟菲斯的 Colossus 2 数据中心供电。这些机组来自 ProEnergy，该公司重造的是波音客机上常见的 GE 发动机。它们曾是载客的发动机。
The practice has spread past one company. In 2025, OpenAI followed with gas turbines at its first Stargate site in Abilene, Texas. Crusoe, the Denver-based startup building that campus, ordered 13 of ProEnergy's converted units in April, then walked away from a $1.25 billion deal to buy 29 natural gas turbines from Boom Supersonic in September. Each order is a schedule decision first.这种做法已不止一家公司。2025 年，OpenAI 在得州阿比林的首个 Stargate 站点也用上燃气轮机。建设该园区的丹佛初创公司 Crusoe 在 4 月订购 13 台 ProEnergy 改装机组，9 月又放弃了一笔 12.5 亿美元、购买 29 台 Boom Supersonic 天然气轮机的交易。每一笔订单首先是工期决定，其次才是成本决定。
When the utility says 2030s当公用事业公司说 2030 年代
The delays are already costing operators business. Last month, Microsoft pulled out as the anchor customer for Nscale's data center in Loughton, England, after the local utility said it could not deliver enough power until the early to mid-2030s. On-site generation is bought to avoid exactly that outcome, at a price per megawatt that nobody calls cheap. A date a decade out is not a plan.延迟已经在让运营商丢生意。上月，微软退出 Nscale 位于英格兰劳顿的数据中心锚定客户角色，因为当地电网表示要到 2030 年代中期才能提供足够电力。现场发电正是为了避开这种结局，代价是没人会称便宜的每兆瓦成本。一个十年之后的日期不算方案。
Policy pushes the same way. The Trump administration has been encouraging data centers to generate their own electricity, which lowers the political cost of going off-grid. This site has covered the grid-protection push to make large loads pay for the capacity they need, and the Memphis data center fight that ran alongside the turbine installation.政策也在往同一方向推。特朗普政府鼓励数据中心自行发电，这降低了离网的政治成本，也削弱了反对者的理由。本站报道过要求大型负载为所需容量付费的电网保护计划，也报道过与这批机组同城的孟菲斯数据中心诉讼。
The efficiency and emissions trade-off效率与排放的代价
Converted jet engines come with trade-offs. They are less efficient and pollute more than turbines designed for conventional gas plants, and it takes more of them to make the same amount of power, according to the Times. That may ultimately make converted jet engines a short-term play rather than a fixture of the grid. Lower efficiency also means more fuel burned for each megawatt.改装喷气发动机有代价。据《纽约时报》，它们比常规燃气电站所用的轮机效率更低、污染更大，而且要更多台才能发出同样多的电。这可能最终让改装喷气发动机只是个短期方案，而不是电网的固定配置。效率更低也意味着每发一兆瓦要多烧燃料。
Some experts expect efficiency and environmental concerns to grow in importance in a year or two, TechCrunch reported, which would make today's arithmetic look short-sighted. The engine is a bridge technology, bought because the alternative is waiting years for firm supply, not because it is cheap or clean per megawatt delivered. Bridges get replaced once the road opens, and nobody pretends otherwise.一些专家预计，效率与环境方面的担忧在一两年内会变得更受重视，TechCrunch 报道，那会让今天的算法显得短视。这是一种过渡技术：买它不是因为每兆瓦便宜或清洁，而是因为另一条路是等待数年才能拿到稳定供电。路一旦通了，桥总会被拆掉。
Why speed beats efficiency now为什么现在速度压倒效率
For a hyperscaler, a delay is a stranded asset. A campus built for accelerators earns nothing while it waits for a connection, so a costlier, dirtier megawatt can still be the rational purchase if it arrives two years earlier. The engine is a financial instrument as much as a power source. Idle capital is the one cost a buildout cannot amortise.对超大规模运营商来说，延迟就是搁浅资产。为加速器建好的园区在等电时一分钱不赚，所以更贵、更脏的一兆瓦若能早两年到位，仍然是理性采购。发动机既是电源，也是一种金融工具。闲置的资本是建设计划唯一无法摊销的成本，而这项成本每天都在增加。
This site has tracked how OpenAI's compute buildout has been renamed and re-scoped around power constraints, and how Meta's bond sale is financing campuses that need firm supply. The jet engine is what those plans look like when the grid cannot move at their pace, and the schedule is set by a utility that answers to regulators.本站追踪过 OpenAI 算力园区如何在电力约束下改名与重划，也追踪过 Meta 的债券发行如何为需要稳定供电的园区融资。当电网跟不上节奏时，喷气发动机就是这些计划的样子，而工期由公用事业公司决定，融资条款又跟着工期走。
What is established, what is not哪些已确定，哪些还没有
Established: some AI data centers are using converted jet engines; xAI installed eight in Mississippi for Colossus 2; Crusoe ordered 13 ProEnergy units for Abilene; a 100-megawatt grid connection in Northern Virginia takes about seven years by the IEA's estimate; Mitsubishi Power deliveries are running to about 2031. Not established: how much electricity the converted fleet produces in total, and what it emits.已确定：部分 AI 数据中心在用改装喷气发动机；xAI 在密西西比为 Colossus 2 装了八台；Crusoe 为阿比林订购 13 台 ProEnergy 机组；按国际能源署估算，北弗吉尼亚接入 100 兆瓦约需七年；三菱动力交付排到 2031 年前后。未确定：这支改装机队的总发电量，以及它的排放量。
The open question is whether these engines stay a stopgap. If grid queues shorten or turbine capacity expands, the economics flip back toward the utility, and the engines become scrap again. Until then, the loudest signal from the AI buildout is not a model launch but a retired aircraft engine burning natural gas in Mississippi, bought for the calendar rather than the fuel bill.未解的问题是它们会不会一直是权宜之计。如果并网队列缩短或轮机产能扩张，经济账会翻回公用事业一侧，这些发动机又会变回废铁。在那之前，AI 建设最响的信号不是某场模型发布，而是一台退役客机发动机在密西西比烧着天然气。
