America needs much more power to win the AI race. How are we realisticly going to be able to pull this off? To me we are talking about 2 or 3 years at most. Will we have the power that quickly?
The US will not close the power gap in 2–3 years — natural gas plants are the fastest lever and can come online by 2027–2028, but grid interconnection backlogs and aging transmission mean a genuine crunch is baked in through at least 2028.
Why it matters: AI companies are racing to deploy compute that requires power the grid cannot yet deliver, which means data center buildouts will stall or costs will spike before supply catches up.
- The demand target is enormous: AI data centers need roughly 29 GW of additional power by 2027 and 67 more GW by 2030; Anthropic projects the US AI sector alone needs 50 GW of new capacity by 2028.
- Natural gas is the fastest path — the US nearly tripled its gas-fired capacity in development in 2025, a buildout that could expand total US gas power by 50% if completed, with new plants coming online in 2–3 years.
- Nuclear helps at the margin but not at scale in this window: Three Mile Island's 835 MW restart delivers for Microsoft by 2027; small modular reactors (SMRs) won't be commissioned until post-2030.
- The hard bottleneck is interconnection, not just generation — roughly 2,300 GW of projects sit in queue, and the median wait from application to commercial operation has doubled to over 4 years since 2000, meaning new power plants can be built but struggle to connect to the grid in time.
- Goldman Sachs and some utility analysts argue the natural gas sprint plus nuclear restarts can substantially close the gap by 2028 if permitting is streamlined under current federal policy — they point to the scale of gas capacity now in development as underappreciated.
- The IEA and Brookings take a harder line: interconnection queue timelines and transmission constraints are structural, not just regulatory, and cannot be reformed fast enough to prevent a multi-year capacity shortfall regardless of how many plants break ground today.
