DALLAS (AP) – The major electric power provider for much of North and West Texas says it is considering closing or reducing operations at some of its coal-fired plants to meet new federal clean-air rules.

Dallas-based Energy Future Holdings Corp. owns Luminant Generation Co. In a filing with the U.S. Securities and Exchange Commission Wednesday, it said it’s considering the shutdowns or slowdowns of its plants and mines, as well as seasonal or temporary shutdowns. It’s also considering installing scrubbers to remove sulfur dioxide from plant emissions.

It’s unclear from the filing how the company is leaning and which plants are likeliest to be affected.

Energy Future Holdings also owns TXU Energy to transmit the electricity Luminant generates and Oncor to market it.
