Wisconsin grid approval threatens Oracle’s 2027 data centre target
Oracle’s planned AI datacentre in Port Washington, Wisconsin, could miss its target of delivering capacity to customers in the second half of 2027. The grid connection needed to power the campus is awaiting regulatory approval, and analysts say the delay could push supply beyond Oracle’s target.
American Transmission Company must receive approval from Wisconsin regulators before it can begin building the connection. After the regulator closed its original case because it no longer considered the application complete, ATC refiled in September. Aterio’s base case forecasts partial power in December 2027 and full supply in October 2028; even its earliest scenario would leave little time for testing before service. The 902 MW campus is expected to require 1.3 GW of electricity, while Oracle faces rising investment demands and has reportedly sought payment deferrals for a separate New Mexico project.

Oracle is building a large artificial intelligence data centre in Port Washington, Wisconsin, to provide computing capacity to its customers. The company had targeted the facility becoming operational in the second half of 2027, but regulatory delays threaten to push that timeline back significantly.
The data centre requires a substantial electrical connection to the grid to operate. American Transmission Company must obtain approval from Wisconsin regulators before constructing this connection. After the regulator deemed the original application incomplete, the company refiled in September, causing delays to the overall project schedule.
Current forecasts suggest the data centre could have partial power only in December 2027, with full capacity not arriving until October 2028. Large data centres of this scale are crucial infrastructure for the technology industry, and delays affect the customers who rely on the processing power they provide. Oracle is also facing rising investment pressures elsewhere and has sought payment deferrals for other projects.
