Open question: who pays if a data center cancels after the grid was rebuilt for it
Transmission upgrades built for a single large load take years and outlive any one customer. No instrument in this atlas settles what happens when the load never arrives or leaves early. Britain orders its queue by readiness, Ireland demands matching generation, and United States bills propose cost allocation, but none answers the cancellation case directly.
The verdict
Open question
No settled answer exists. The ledger poses the question, links the live debate, and does not answer it.

- Added
- Britain's Gate 2 test asks whether a project is ready and needed before it holds a queue position, which reduces speculative requests but does not price a later cancellation.
- Ireland requires matching generation or storage, which shifts capital to the customer but does not address abandoned network build.
- United States proposals debate who pays for local transmission upgrades, and FERC's large load docket lists no final rule.
- The exposure falls on whoever signed the network build, which in most systems means the general body of ratepayers.
What it changes
For an operator, a utility or a community
An operator should expect exit terms, security and take or pay conditions to become the negotiating ground rather than the connection date. A utility should read every fast track as a question about who carries the stranded asset. A community asking one question at a hearing should ask this one: if the campus is cancelled in year four, who pays for the line.
