Accident Classified As:

Cause of Problem: Power Failure

A power failure occurred as a result of grid failure due to scheduled maintenance by Entergy. Entergy's method did not allow for ConocoPhillips to secure an alternative source while the main grid was down. The refinery thus had to initiate an emergency shutdown. As a result, the refinery had to employ the low pressure flare.

Discharge Preventable - No

Unanticipated power failure.

Notes/Remedial Actions

Entergy has proposed a three phase project that will build additional substations within the electrical power grid over the next five to eight years to improve its reliability. Entergy is currently seeking federal funding for this project.
