MEXICO CITY (AP) — Mexico said Thursday it was temporarily suspending an offer to provide electricity to Texas to help the U.S. state weather an ice storm that forced rolling blackouts, because of severe cold in Mexico's own territory.
Mexico's Federal Electricity Commission had said Wednesday it had agreed to transmit 280 megawatts of electricity to Texas.
But on Thursday, the commission said it was temporarily suspending the transfer because below-freezing temperatures in northern Mexico had affected the generating capacity of some its own plants, causing a reduction of about 1,000 megawatts in generation.
The commission also said Mexico needed to ensure there was enough electricity to meet domestic demand, in the face of a severe cold snap that dumped snow on the border city of Ciudad Juarez, across from El Paso, Texas.
