About Port Arthur
What you're shopping for power in.
Port Arthur is a major Gulf Coast refining city southeast of Beaumont — Motiva, Total, and Valero all run massive refineries here. Population has declined as the petrochemical industry consolidated.
Climate & bill pattern
Sub-tropical Gulf Coast climate with serious hurricane corridor exposure (Harvey, Rita, Ike all hit hard).
Older housing stock (often pre-1990, 1,400-1,800 sq ft) with weak insulation — humidity drives long AC season and high bills per square foot.
