Adds Motiva.
Texas refineries reported restarting units shut last week after subfreezing temperatures and a power crisis abruptly cut 28pc of US crude processing capacity.
Motiva was today restarting the single largest US refining complex, its 600,000 b/d refinery in Port Arthur, following a shutdown last week. Refineries in Corpus Christi, including Valero's 293,000 b/d site and Flint Hills Resources' 296,000 b/d refinery, reported restart work underway this week. ExxonMobil said it was beginning restart work at its 362,000 b/d refinery in Beaumont, Texas.
Subfreezing conditions forced electricity and natural gas curtailments that reduced or shut down more than 5.1mn b/d of Texas refining. Conditions affected nearly every refinery in the state, from near the Louisiana border to the western edge in El Paso.
The Electric Reliability Council of Texas (ERCOT), which operates the electrical grid covering most of the state, lifted emergency conditions on 19 February. Natural gas curtailments ordered by the Texas Railroad Commission, a state energy regulator, remain in effect until tomorrow.
Electrical transmission infrastructure and refineries both appeared to avoid major damage when storms began cutting across the region on 14 February, supporting a faster recovery for energy infrastructure.
