Gulf Coast gasoline strengthened for a second day after Valero Energy Corp.’s Port Arthur refinery had a power failure and compressors tripped offline at Motiva Enterprises LLC’s plant in the Texas city.
There wasn’t a material impact to production from the 10-minute outage at the Valero refinery, Bill Day, a company spokesman based in San Antonio, said in an e-mail. Motiva’s compressors tripped because of high pressure, according to a filing with state regulators.
