Oracle Corp. shares moved lower on Wednesday after a new report raised concerns about delays at the company’s major artificial intelligence data-center project in Wisconsin.
The report suggests that the project is facing a serious obstacle: access to enough electricity.
Oracle stock fell about 1.8% after infrastructure data provider Aterio highlighted the issue. The report argues that power availability, rather than funding or semiconductor supply, is becoming one of the biggest challenges facing companies building large-scale AI infrastructure.
Oracle did not immediately respond to requests for comment on the report.
Oracle’s Wisconsin AI Campus Faces a Power Bottleneck
Vantage Data Centers is currently developing the 500-acre “Project Lighthouse” campus for Oracle in Port Washington, Wisconsin.
Construction at the site is moving forward quickly. Permits have been secured, and two of the planned four buildings are already enclosed.
However, the campus still lacks the power connection needed to begin operating its computing infrastructure.
According to Aterio, the facility cannot run its servers until American Transmission Co. completes a new high-voltage transmission line connecting the campus to the broader electricity grid.
Regulatory Delays Threaten Oracle’s Timeline
The power project has run into regulatory problems.
The Public Service Commission of Wisconsin recently withdrew its initial approval and restarted the legal review process after developers submitted hundreds of changes to the project.
That decision could significantly delay the transmission line.
As a result, Oracle may struggle to meet its goal of beginning operations at the site during the second half of 2027.
Under Aterio’s most likely scenario, the campus may not receive meaningful electricity supplies until early 2028.
If regulators take a full year to review the revised proposal, the site may not reach its full power capacity until April 2029.
Aterio noted that such a review period would not be unusual for a utility project of this scale.
Electricity Becomes a Major AI Infrastructure Challenge
The situation highlights a growing problem for technology companies investing heavily in artificial intelligence.
AI data centers require enormous amounts of electricity to power servers, cooling systems, and other infrastructure.
As companies such as Oracle expand their AI capacity, access to reliable power grids is becoming increasingly important.
In some cases, energy infrastructure may now represent a bigger constraint than capital or access to advanced chips.
Oracle Also Faces Questions Over New Mexico Project
The Wisconsin concerns come shortly after Oracle issued another warning related to a separate infrastructure project.
The company recently said it could delay payments tied to “Project Jupiter,” a large data-center campus in New Mexico.
Oracle cited delays involving natural-gas pipelines and pending air permits.
Despite those issues, the company has maintained that the New Mexico project remains on schedule.
Still, the emergence of challenges at two major developments in quick succession may increase investor concerns about execution risks tied to Oracle’s rapid AI infrastructure expansion.
AI Expansion Brings Growing Execution Risks
Oracle is investing heavily in data centers as demand for artificial intelligence computing continues to rise.
However, large infrastructure projects depend on more than simply building facilities.
Power availability, transmission infrastructure, permitting, and regulatory approvals can all affect when a new data center becomes operational.
The reported Wisconsin delays show how these issues can create uncertainty even when physical construction is progressing quickly.
For investors, the key question will be whether Oracle can keep its major AI infrastructure projects on schedule while managing increasingly complex energy and regulatory requirements.
