AlohaNAP data center expansion (Kapolei)

Also called: AlohaNAP Phase 1 expansion, 1547 HAII1

AlohaNAP is a small data center in Kapolei that links to undersea internet cables. Its owners are adding a 1.5-megawatt building, which would bring the site to about 2.7 megawatts. They also talk about a much bigger 50,000-square-foot building later.

👥 Reported, not confirmed yetSourceLast checked: Oct 8, 2026

Where things stand: New owners announced a 1.5-megawatt addition in October 2024. Data center trackers list it as under construction in 2026. A later, much bigger 50,000-square-foot building is only an idea so far.

🕒 Latest update (Oct 22, 2024): Harrison Street and 1547 bought AlohaNAP and announced a 10,300-square-foot, 1.5-megawatt addition for about 200 more server racks.
