Questions the public record still needs to answer.

These are diligence prompts. General reference sources below are not verified project-specific approvals, utility agreements or incentive awards.

Land use and jurisdiction

Which parcel, legal jurisdiction and land-use approvals apply to ORNL Discovery and Lux AI supercomputers?

The register describes a multi-site program; no single campus approval is implied. No locality-matched land-use reference is recorded in this packet; consult the actual governing jurisdiction.

Electric service

What site-specific utility service agreement, interconnection milestone and delivery date are documented?

Reviewed disclosure: Not disclosed in cited source. A campus specification is not an energized utility commitment. The general TVA and local power company references do not identify the serving utility, governing rate or service agreement for this particular site.

Environmental and water review

Which air, water and cooling records apply to the actual site and phase?

The register does not establish a project-specific water allocation or final environmental approval.

Reuse qualifications

This is a public research packet, not a legal, tax, engineering or investment opinion.
A source association is not proof of a final permit, utility commitment, incentive award or completed project.
Campus and multi-site program scopes are different. Do not sum overlapping program and campus investment or capacity figures.
Publication dates, desk review dates and project milestones have different meanings. An export is not a new source verification.
Unknown or undisclosed values remain unknown; locality markers are approximate and do not establish parcel jurisdiction.
