1、 itif.org The United States Needs Data Centers,and Data Centers Need Energy,but That Is Not Necessarily a Problem ROBIN GASTER|NOVEMBER 2025 Electricity demand is growing rapidly and starting to strain the grid.Instead of slowing the growth of data centers,the United States should deploy new technol

2、ogies and strategies to efficiently increase grid capacity while accelerating new generation and transmission.KEY TAKEAWAYS Demand for electricity is rising fast,and that will likely continue.Data centers appear to be significant drivers,which has prompted calls to slow their growth or even prevent

3、them from connecting to the grid altogether.The United States should instead squeeze more power from the existing grid without negatively impacting customers,while also building new capacity.New technology can increase supply from existing transmission lines and generators.That can bridge the transi

4、tion to an expanded physical grid.On the demand side,there is spare capacity,but not at peak times.Large users such as data centers can be encouraged to shift demand to off-peak periods,without damaging their customers.Grids do some of that already,but much more is needed.Up to 40 percent of data ce

5、nters needs are not highly time sensitive,so they can be partners in managing peak demand by proactively shifting some of their use to different times and even different geographies.Regulators should change incentives for utilities,enact planning reforms,launch new demonstrations and pilots projects

根据报告的内容,全文主要内容概括如下: - **电力需求增长迅速**:数据中心和其他因素导致电力需求快速增长,预计到2028年将占全国电力的6.7-12%。 - **电网容量有限**:电网为峰值需求设计,存在大量闲置容量,但激活这些容量和确保峰值需求满足是挑战。 - **需求侧解决方案**:数据中心可通过时间转移、地理转移、UPS利用、冷却灵活性、AI感知调度和合同需求响应等方式调节峰值需求。 - **供应侧解决方案**:动态线路评级(DLR)、重新导线、功率流控制和拓扑优化、电池和虚拟电厂等技术可提高现有电网的容量。 - **经济性**:与新建输电线路和发电设施相比,这些解决方案具有成本效益、可扩展性和快速部署的优势。 - **政策建议**:需要监管机构、公用事业公司、客户和政府共同努力,以实现电网的过渡和满足不断增长的电力需求。
