What happened
Morgan Stanley research notes published between September and October 2026 argue that a shortage of electricity, not chips, is becoming the binding constraint on US AI data center buildouts. The bank defines a powered shell as a building with a grid connection or on-site generation, ready to receive servers, and says grid connections, substations and heavy electrical equipment can take several years to secure.S1
In its September 21, 2026 report, the bank raised its estimate of cumulative US data center power demand for 2026-2028 to 97 GW, about 43% above the earlier 68 GW forecast. After subtracting roughly 21 GW under construction and around 19 GW of available or contractable grid capacity, the gross gap grew to 57 GW from 38 GW.S1 On-site gas turbines and engines (about 19 GW by 2028), Bloom Energy fuel cells (around 6 GW) and nuclear-adjacent sites (about 3 GW) are probability-weighted to roughly 24 GW, leaving a net shortfall of about 33 GW, or 34% of the power needed for chips expected to ship in the period.S1
The midpoint gap grows from about 5 GW in 2026 to around 12 GW in 2027 and 33 GW in 2028; extending to 2029 pushes demand to 165 GW with a residual gap of roughly 72 GW. Morgan Stanley notes these are model estimates from projected chip shipments, not utility-approved capacity.S1 The revision reflects rack-scale AI: racks around the Nvidia Vera Rubin platform are now modeled at about 234 kW, up from 149 kW, with Rubin Ultra expected near 600 kW per rack.S1
Corroborating the pressure, PJM Interconnection failed for the first time in its December 2025 capacity auction to meet its reliability target, ending about 6.6 GW short for the delivery year starting June 2027; Northern Virginia's Ashburn cluster sits inside PJM. Powered shell lease rates rose from about $1.80 per watt in summer 2025 to $2.30-2.40. Hut 8 signed 704 MW of leases at Beacon Point, and TeraWulf agreed a 20-year, roughly 401 MW lease with Anthropic in Kentucky. An October 5, 2026 follow-up note says Nvidia and Broadcom are relatively protected, while memory, optical module, power management and analog suppliers are more exposed to order postponements or cancellations.S1

| 2026-2028 US demand forecast | 97 GW (up from 68 GW) | S1 |
| Net shortfall (2028 cumulative) | about 33 GW (34% of need) | S1 |

| PJM auction shortfall | about 6.6 GW (delivery year from June 2027) | S1 |

Background timeline
- - Powered shell lease rates stood at about $1.80 per watt of IT capacity [S1].
- - PJM's capacity auction failed for the first time to secure enough resources, ending about 6.6 GW short [S1].
- - Start of the PJM delivery year affected by the auction shortfall; date used as the auction's delivery start disclosed by the source.
- - Protests against new data centers were held in dozens of states; several local councils considered moratoriums [S1].
- - Morgan Stanley raised its 2026-2028 demand estimate to 97 GW and the gross gap to 57 GW [S1].
- - Morgan Stanley published a follow-up note on semiconductor supply chain consequences [S1].
- - SupplyStatus reported the power shortage as still developing rather than easing [S1].
XAIPART take
Technical impact
Rack densities moving from 149 kW to about 234 kW, and toward 600 kW with Rubin Ultra, push demand toward busway, breaker and power distribution hardware rated far above legacy racks, and make liquid cooling infrastructure mandatory rather than optional. Designs locked to lower per-rack budgets may need electrical re-specification before 2028 deployments.
Market impact
The October 5 note flags memory, optical modules, power management and analog chips as the most exposed lines: if a site slips months for lack of power, operators can push out or cancel POs, triggering inventory corrections even while memory stays tight. Buyers should expect lead times for transformers and gas turbines, already multi-year per the source, to stay long, and powered shell pricing to keep climbing given the $4.50-per-watt value of one year of earlier energization.
Action
Procurement teams building 2027-2028 US AI capacity should tie component release schedules to energization milestones, not chip availability, and negotiate push-out or cancellation clauses on power-management and optical orders. Qualifying on-site generation-adjacent sites (gas, Bloom Energy fuel cells, nuclear co-location) early protects the deployment dates that component orders depend on.
XAIPART Forecast
XAIPART expects at least one publicized cancellation or multi-quarter postponement of memory or optical module orders tied to a delayed US AI data center buildout by Q3 2027; if the PJM 6.6 GW shortfall is fully covered and 2027 deployments proceed on schedule, this forecast is wrong.

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. The shortfall figures are single-source Morgan Stanley model estimates based on projected chip shipments, not utility-approved capacity, and no independent confirmation is available.
