AI'S NEXT BOTTLENECK MAY BE THE GRID
PJM is screening which proposed data-centre loads are likely to be real for its 2027 forecast. The Veyro signal is simple: in the AI buildout, grid access is becoming as strategic as compute.

A critical infrastructure constraint has emerged: AI's next bottleneck may be the electrical grid, not silicon or models.
PJM Interconnection, America's largest grid operator, has initiated a formal screening process to determine which proposed data-centre interconnect loads will actually materialize before 2027.
WHAT HAPPENED: PJM has begun filtering large-load requests using stringent commercial criteria to prevent speculative bookings from distorting long-term capacity planning.
WHO IT AFFECTS: Northern Virginia and Mid-Atlantic hyperscalers face multi-year substation interconnect queues, directly impacting GPU cluster deployment timelines.
WHY IT MATTERS: Power availability is now the primary gating factor for AI scaling. Projects with secured interconnect access command an escalating valuation premium.
Why it could matter
If grid access becomes the gating factor, AI growth will depend not just on chips and servers, but on which projects can actually connect to power.
What was reported and who could be affected
What was reported
PJM has started reviewing proposed large-load adjustments for its 2027 forecast, using new rules to test which projects are likely to be real.
Who could be affected
Data-centre developers, hyperscalers, utilities, and other large power users could be affected as power demand forecasts become more selective and more important.

PJM begins 2027 large-load review
knownPJM, the largest U.S. grid operator, has begun reviewing proposed large-load adjustments for its 2027 long-term forecast, using new guidelines to judge which projects are likely to actually materialize.
ReutersData-centre demand is driving the review
knownPJM says the review is being driven mainly by rising electricity demand from data centres and other large power users across its regions.
ReutersFast grid access is gaining value
inferredPower projects that can connect to the grid quickly are attracting a premium in fast-growing data-centre markets, suggesting that grid access itself is becoming a strategic part of AI infrastructure.
ReutersWhich proposed loads will make the final forecast?
UNKNOWN · WATCHINGPJM has not yet published its final 2027 load adjustment. CRA findings are due in October, PJM's final adjustment is expected in November, and the full forecast is due in January.
