The full record

Status note
NBC4 (March 2026) quotes an Ohio EPA official saying the facility is in operation, and Signal Cleveland (Feb. 2026) describes the 142-acre campus as built and operating. A 72.9 MW AEP Ohio fuel cell plant for the campus is planned; Hilliard dropped its permit appeal Sept. 15, 2026.
Power note
72.9 MW is the AEP Ohio on-site fuel cell plant serving the campus (OPSB case 25-0649-EL-BLN), not the campus IT load.
