- Oracle’s Wisconsin campus might have completed buildings lengthy earlier than electrical energy arrived
- Regulators withdrew their completeness discovering after ATC filed 564 further paperwork
- Ten months of overview ended with no determination and restarted from zero
Oracle’s large 1.3 GW AI information heart campus in Wisconsin, dubbed Undertaking Lighthouse, faces extreme energy delays after regulators restarted the overview wanted to attach it to the grid.
The campus in Port Washington is being developed by Vantage for Oracle, with 4 information facilities deliberate throughout the location.
Development is advancing, however the campus can not start serving clients at scale till the required transmission infrastructure receives regulatory approval and will get constructed.

A overview clock reset to zero
In September 2025, American Transmission Firm (ATC) requested the Public Service Fee of Wisconsin (PSC) to approve the brand new high-voltage line serving the campus.
By December 2025, the PSC discovered the appliance full and started its formal overview, which began the authorized countdown for a choice.
Nonetheless, between January and July 2026, ATC altered the venture and filed 564 extra paperwork that modified routes, launched momentary bypass strains and up to date price estimates.
An administrative legislation decide ordered ATC on 1 July to itemize every alteration and located on 15 July that the corporate had not complied.
As a result of the PSC lacked confidence concerning the precise scope beneath overview, it withdrew its completeness discovering in August 2026, ten months after the case opened.
Such late additions would wish additional environmental overview that the authorized deadline left no room for, so the venture risked approval by default.
The PSC closed the case on September 10 2026 with out ruling on the deserves, and ATC refiled on September 18, restarting the statutory clock.
Buildings can advance earlier than electrical energy arrives
Development itself doesn’t seem to face the identical scheduling drawback affecting the transmission connection serving the Wisconsin campus.
“Development at Port Washington is progressing steadily, however energy supply relies on a regulatory course of that has restarted,” mentioned Javier Reyes, Head of Knowledge Middle Analysis, Aterio.
Permits have been secured, work has continued since December 2025, and imagery from September reveals two buildings already enclosed.
The remaining constructions are nonetheless present process development, whereas tools set up continues inside parts of the finished buildings on the web site.
Vantage describes the campus as carrying 902 MW of IT demand, whereas utility information describe 1.3 GW of complete electrical necessities.
These figures differ as a result of the bigger measurement consists of cooling and different consumption past electrical energy reaching computing tools.
The primary transmission stage may present solely partial service, and Vantage beforehand requested ATC about supplying roughly 310 MW throughout 2027.
That request additionally projected 438 MW of peak demand throughout 2027, adopted by 1.3 GW from 2028 onward throughout the campus.
Consequently, preliminary grid entry wouldn’t routinely imply each constructing may instantly help buyer workloads at its supposed capability.
An extended regulatory overview would shift partial service towards June 2028 and full 1.3 GW availability towards April 2029, properly past Oracle’s steerage.
“Based mostly on the general public document, we see a significant danger that load arrives later than Oracle’s present steerage,” Reyes added.
