What I do hear about is this (possibly outdated, I'm increasingly noticing the references there are not kept up to date) claim on Wikipedia:
> On October 13, 2009, the Tres Amigas SuperStation was announced to connect the Eastern, Western and Texas Interconnections via eight 5 GW superconductor links, although the Texas Interconnection does not intend to connect for regulatory reasons. The Eastern Interconnection withdrew from the project in 2015, rendering the project moot. Construction was never started.
