Texas energy company threatens to cut off plants powering 400,000 homes

• Energy Transfer is run by Dallas billionaire Kelcy Warren, who donated $1 million to Gov. Greg Abbott's re-election campaign.

Context: After a catastrophic grid failure last year that led to hundreds of deaths, Energy Transfer made a reported $2.4 billion.

• The Texas grid has already shown some problems as temperatures have dropped.

What's happening: Luminant's parent company, Vistra Corp., filed a 149-page document with the Texas Railroad Commission, which oversees energy matters. The filing included a letter from Energy Transfer stating that if payment is “not received within ten days” it would no longer “deliver gas” to Luminant's gas-fired plants.

• Energy Transfer sent a response to the commission stating that it will continue to supply Luminant's plants with natural gas while it tries to work out the fee dispute and asked the commission to delay any rulings for now.
• Railroad Commission officials have not responded to questions about whether the agency will act, per the Texas Tribune.

What they're saying: Energy Transfer's threat to cut off service in the middle of winter is “illegal and grossly irresponsible and should be prohibited by this commission,” Vistra says in the filing.

• Railroad Commission Chair Wayne Christian tweeted: "I am paying close attention to this. @EnergyTransfer and @VistraCorp must come together to resolve this issue so that no Texans lose gas or electric service during cold weather. Do what's right for Texans."
