With a city population of approximately 56,039 and a median household income of $35,424 in Jefferson County, keeping energy costs manageable is a real priority for Port Arthur families.

As of March 2026, residential customers in the 77641 zip code pay an average rate of 12.4¢/kWh through Entergy Texas, Inc. Because this is a fully regulated utility territory, there is no range of competing retail rates to compare — the rate you pay is determined by Entergy Texas and approved by the Public Utility Commission of Texas (PUCT). That said, 12.4¢/kWh is relatively moderate compared to statewide averages in Texas, which have fluctuated between 11¢ and 15¢/kWh depending on market conditions. Your bill is made up of both the energy supply charge and regulated delivery charges, both of which are set by Entergy Texas under PUCT oversight.
Because 77641 is served by a regulated utility, there are no short-term, medium-term, or long-term retail electricity contracts to evaluate. You are automatically on Entergy Texas's standard residential tariff. There are no fixed-rate or variable-rate plan decisions to make. However, Entergy Texas does offer budget billing programs that spread your annual electricity costs into equal monthly payments — a useful tool for households in Jefferson County trying to avoid high summer bills when Southeast Texas heat drives up air conditioning usage significantly.

Port Arthur sits in the heart of the Gulf Coast industrial corridor, and Jefferson County's economy is heavily tied to petrochemical refining and maritime industries. Summer months — particularly June through September — drive electricity demand sharply higher due to the region's intense heat and humidity. March 2026 represents a transitional period where bills are typically lower before peak cooling season begins. Residents should use this window to schedule energy audits, upgrade insulation, or install programmable thermostats to reduce the impact of summer rate increases.
Enroll in Entergy Texas's Budget Billing program to spread high summer cooling costs evenly across 12 months — Port Arthur's May-through-October heat regularly spikes bills by 40–60% above the winter average, making predictable payments a real financial relief.
Take advantage of Entergy Texas's appliance and HVAC efficiency rebates before replacing old equipment. Gulf Coast humidity means your air conditioner runs nearly year-round; upgrading to a high-SEER unit with a utility rebate can trim hundreds of dollars from your annual bill.
Seal attic penetrations and add blown-in insulation rated for humid climates — Port Arthur's extreme humidity accelerates moisture infiltration that degrades standard insulation, reducing its effectiveness and causing your cooling system to work harder than necessary.
Contact Entergy Texas to inquire about the Low-Income Home Energy Assistance Program (LIHEAP) and the company's own Helping Hands assistance fund. With Port Arthur's median household income well below the state average, these programs can provide meaningful bill relief for qualifying families.
