⚡ Your electric company
Depending on where you live in San Marcos City: Pedernales Electric Co-op, Inc. (co-op (owned by its members)) or Bluebonnet Electric Co-op, Inc. (co-op (owned by its members)) or City of San Marcos (run by the town).
In much of Texas you can pick who sells you power, but this company owns the power lines.
Big data centers need a lot of power. Who pays for new power lines depends on state rules. See the rules in Texas.
