What changed, and why.

Lifecycle events are dated evidence attached to a stable entity. Corrections name the field, the previous value, the new value and the source. Neither list is a second facility count.

Corrections

  1. Correction · 11 September 2026 · internal review

    Record → Statewide count

    Changed correction

    From Ohio's consumer advocate repeats a commercial directory count. It is useful as a market signal, but the underlying unit can include buildings, suites and campuses and is not a state census. DataCenterData does not adopt 200+ as its own count.

    To Added the wording difference between OCC's web fact sheet and its PDF fact sheet. Verdict unchanged.

  2. Correction · 11 September 2026 · internal review

    Record → Power / rates

    Changed correction

    From The PUCO-approved AEP Ohio tariff allocates substantial underuse and cancellation risk to new loads over 25 MW. That is real protection against stranded distribution investment; it is not proof that generation, transmission or wholesale-market costs can never affect household bills.

    To Added how the 85% minimum-demand term works by contract size and AEP's count of pre-tariff contracted load. Verdict unchanged. The 72.5% and 82.5% shares are DataCenterData arithmetic from AEP's published formula (15,000 kW plus 85% above 25,000 kW up to 75,000 kW; 57,500 kW plus 100% above 75,000 kW; capped at 85% of contract capacity).

    Record → Water / permits

    Changed correction

    From Draft Ohio data-center general NPDES permit treated as if it were a final, measured water authorization.

    To Ohio EPA said on July 21, 2026 that it would not finalize draft OHD000001 and would continue with individual NPDES permits. A permit is not measured discharge.

    Changed correction

    From At least 1,000 baseline; AWS's own July 2026 account says nearly 1,000 operations staff hired; an undated Chamber project page says 1,056 full-time AWS employees

    To 2026-09-11: status was 'supported-as-delivered' with value 'At least 1,000 baseline; 1,056 full-time AWS employees later reported'. The company-linked counts sit on either side of the baseline (AWS op-ed: 'We have also hired nearly 1,000 operations staff so far'; Chamber page: '1,056 full-time AWS employees', undated), so the reviewed record does not support a delivery conclusion. Evidence level unchanged.

    To The 2 March 2026 council minutes record unanimous adoption of Resolution R-3-2026, whose agenda title describes rescission of the 2024 Microsoft taxpayer agreement, including termination of the tax abatement. DataCenterData has not obtained the adopted resolution text and therefore does not independently state its full legal effect. IEDC showed the state DATA exemption as a pending accepted offer when checked.
