the ai bottleneck just moved from gpus to the power grid. morgan stanley sees 97 gw of cumulative us data center demand through 2028 against a 34% shortfall, and reports now say half of planned builds are delayed or canceled over electricity.
the chip is no longer the constraint, the outlet is.
Context
Blockspace (September 21, 2026) reports that Morgan Stanley raised its projected US data-center power shortfall through 2028 to 33 GW after onsite generation and other accelerated power solutions. The residual gap equals 34% of the 97 GW of incremental power developers will need, and the shortfall before new power solutions is 57 GW. It describes the figures as model estimates, not utility-approved load.
Business Korea (October 6, 2026) cites a Morgan Stanley report from October 5 with a net shortfall of about 32 GW by 2028. Yahoo Finance (April 3, 2026) reported, citing Bloomberg, that close to half of planned US data center builds this year were projected to be delayed or canceled. SemiAnalysis (June 18, 2026) argued that the claim that half of 2026 capacity is canceled is wrong.
The 97 GW and 34% figures match Blockspace. The 97 GW is incremental power needed, described in the report as projected demand through 2028, and the note's 'cumulative' fits. The 34% is the residual shortfall after accelerated power measures, and Business Korea gives a slightly different 32 GW from a report dated a few weeks later, so the exact shortfall varies by source.
The note's 'half of planned builds are delayed or canceled' traces to Bloomberg's April 2026 reporting about equipment and power, which SemiAnalysis disputes for 2026 capacity. The claim is contested, and the note treats it as settled.
'The chip is no longer the constraint, the outlet is' is the author's opinion. Morgan Stanley's own point is a modelled power gap, with supply responses that can close part of it.
