Timeline

Start of construction for the first building, according to [Applied Digital](https://ir.applieddigital.com/news-events/press-releases/detail/75/applied-digital-announces-groundbreaking-of). CoreWeave was not leased yet at this site, but this is the construction start date we're using for relevance.

CoreWeave signed the first lease package for 250 MW. No buildings online yet. This is according to an [SEC 8-k filing](https://www.sec.gov/Archives/edgar/data/1144879/000164117225013199/form8-k.htm) from this date.

[A new 150 MW lease](https://ir.applieddigital.com/news-events/press-releases/detail/128/applied-digital-finalizes-additional-150mw-lease-with) brings CoreWeave to 400 MW total contracted. The project is now clearly scheduled to be a three-building CoreWeave campus.

The first 50 MW slice of Building 1 has reached Ready for Service status according to [this report](https://ir.applieddigital.com/news-events/press-releases/detail/133/applied-digital-achieves-ready-for-service-for-phase-1-at). This is the first point where we would count any CoreWeave capacity as operational.

[This Applied Digital report](https://ir.applieddigital.com/news-events/press-releases/detail/137/applied-digital-completes-phase-ii-ready-for-service-at) says the rest of Building 1 has reached Ready for Service, bringing the first building to its expected 100 MW. We can treat this as the first completed data center building.

According to satellite imagery, Building 1 looks complete and in service, with the surrounding power/cooling equipment also operational. (Note: this image doesn't provide a view of buildings 2 or 3, though it's very safe to assume they're under construction at this stage, considering they're still under construction in the satellite image 3 months from now.)

According to satellite imagery, Building 2 is fully roofed and shell complete, with rooftop chillers mostly installed. Building 3 construction is well underway, with about 1/4 of the roofing done and the foundation laid out.

2026-12-31 (projected)

According to the [schedule](https://ir.applieddigital.com/news-events/press-releases/detail/128/applied-digital-finalizes-additional-150mw-lease-with), Building 2 should be online sometime in the second half of 2026. We can estimate the end of 2026 for 250 MW operational.

114 MW
2027-06-01 (projected)

According to [schedule](https://ir.applieddigital.com/news-events/press-releases/detail/128/applied-digital-finalizes-additional-150mw-lease-with), Building 3 should come online in the first half of 2027. That would bring the full PF1 campus to 400 MW, according to the contract.
