TEXAS — Last summer, when the brutal heat strained Texas’ electric grid and increased worries about blackouts, the grid imported a modest amount of power from Mexico and elsewhere in the United States.
“It obviously helped,” said Dan Woodfin, the director of system operations for the Electric Reliability Council of Texas, or ERCOT, the grid operator. Those electricity imports amounted, on some August days, to nearly the equivalent of a nuclear reactor’s output, or enough to power more than 200,000 homes in the summer.
