Power approval set to delay Oracle's Wisconsin AI datacenter

Oracle's Wisconsin AI datacenter may miss its planned 2027 start because the grid connection awaits approval from the Public Service Commission of Wisconsin. Aterio's base case puts partial power in December 2027 and full supply in October 2028.

• Campus rated at 902 MW of computing load and 1.3 GW of total electricity demand
• ATC plans over $2 billion in transmission projects tied to Wisconsin datacenters
• Aterio base case: full power in October 2028, extended review could push it to April 2029
• Oracle also sent a force majeure notice on Project Jupiter in New Mexico
