Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.
Reported lifecycle history
- Proposed
Mason City council approved first reading (4-2) of rezoning of parcels south of 19th Street SW / east of South Pierce Avenue that could allow a data center; land rezoned for industrial use in April 2026; no development agreement in place
Underlying source
Source notes
Roughly 380 acres (mayor's estimate; 'nearly 400 acres') of farmland on the south side of Mason City along 43rd Street SW. KIMT (Sep 2026) reports sources confirmed QTS has expressed interest and a data center company submitted designs, but the city says it has not entered negotiations with any company, so the operator is left undisclosed. Coordinates are an approximate south-side placement, not a parcel point.
