01

Nearly 2,600 GW of generation and storage capacity is queued for grid interconnection. That amount is more than double the current U.S. grid’s capacity.

02

New generation and transmission projects often face delays of 5 to 10 years due to permitting and interconnection queues.

03

Since 2010, the U.S. has retired significant coal and nuclear capacity while failing to replace it with equivalent firm power.

04

Grid operators like NERC began issuing reliability and capacity warnings years before large-scale data center expansion.

05

Large data centers typically fund their own interconnections, on-site substations, and required grid upgrades rather than shifting those costs to households.

06

Historically, electricity demand growth led to lower long-term prices when new generation was built alongside it.

07

Average U.S. retail electricity prices rose roughly 30–40 percent between 2019 and 2023, before most AI-era data center demand came online.

08

U.S. electricity generation grew by less than 5 percent between 2005 and 2022, even as population and electrification increased.

Powering the conditions for progress.

The Project

The Capacity Project is an independent research and analysis initiative focused on energy supply, infrastructure, and system design. We work to make complex energy systems legible and to advance policies that support abundant, reliable, and affordable power.
