Biggest constraint最大约束

Power电力

The biggest constraint is power: any business that wants 10 MW or more must pass a power-system impact assessment, a draft notice sets a higher pass mark in the Seoul area (75 points) than elsewhere (70), and AI data centres outside the metropolitan area are to be exempt below a size still to be set.最大约束是电力：用电 10 MW 及以上的企业必须通过电力系统影响评估；一份草案规定首都圈的通过分（75 分）高于其他地区（70 分）；首都圈以外的 AI 数据中心在尚待确定的规模以下将被豁免。

Thermal meaning热管理含义

With no national PUE rule, the cooling plant is sized by grid access: loads of 10 MW or more need a grid assessment, and the draft pass mark is higher in the Seoul area than elsewhere, so every cooling kW saved is IT capacity. At a 10 K approach a dry cooler alone makes W40 water in about 99% of hours and W32 in about 76% in Seoul (Incheon), which suits warm-water liquid cooling with dry heat rejection.韩国没有全国性 PUE 规则，冷站的规模由并网条件决定：用电 10 MW 及以上要先过电网评估，草案的通过分首都圈又高于其他地区，省下的每一 kW 冷却用电都是 IT 容量。按 10 K 接近温差，首尔（仁川）的干冷器单独可在约 99% 的小时制出 W40 的水、约 76% 的小时制出 W32，适合温水液冷配干式排热。

What is not covered: 未覆盖：In the sources read here no national PUE or WUE requirement for data centres was found; the only PUE scheme is a voluntary certification. A lawmaker told the press she is considering a bill with a PUE standard, but that report could not be quote-checked.
