It is physically connected.

Did you mean not connected in a regulatory sense?

Um, you're right. There are a few physical connections. Still, Texas, which
uses 40% more electricity than California (peak demand in excess of 75GW),
is not really a player in the national grid. 85% of the power generation
companies in Texas have agreed to neither buy nor sell their power outside
the state. The state, therefore, is largely exempt from federal regulatory
oversight.

There are four interconnections to points outside the state (including
Mexico).* Together they have a capacity of about 500 megawatts. There is one
600 megawatt line that connects the Texas grid to points in east Texas that
are part of the "Eastern" U.S. grid, but the service is still designed for
Texans.
