数据中心不是美国电价上涨的普遍原因：PJM 区域差异明显
数据中心拉高美国电价是个流行说法，但这组数据显示 29 个州电价在降，只有 PJM 区域成本明显上升，看数据怎么讲。
Berkeley Lab 与 Brattle 2026 年 7 月的数据显示，经通胀调整后美国全国零售电价仅比 2019 年水平高 3%，29 个州的电价反而下降。但在 PJM 区域，独立市场监测机构 Monitoring Analytics 估算，数据中心需求为 2028/29 年容量市场增加 62.7 亿美元成本，四次拍卖累计 294 亿美元。这些是建模的批发成本，实际传导到家庭用户的比例取决于电力合约和费率。电价影响因地区而异，部分数据中心快速增长的州平均电价反而下降。
Another Data center myth: rising energy cost. More specifically, the idea that data centers are the main reason electricity prices are rising across the US.
The national price data through 2025 do not support data centers as a blanket explanation for rising US power prices.
Inflation-adjusted retail electricity prices across all customer groups were 3% above 2019 levels nationwide and fell in 29 states (Berkeley Lab/Brattle, July 2026).
In the PJM region, however, data centers are contributing to higher costs for securing enough power at peak demand. The independent market monitor estimates that data-center demand added $6.27 billion to capacity-market costs for 2028/29 and $29.4 billion across four auctions (Monitoring Analytics, October 2026). These are modeled wholesale costs. How much reaches households depends on utility contracts and rates.
The impact of data centers on electricity prices varies by region. In some states with substantial data-center growth, inflation-adjusted average prices have fallen.
