Delivery charges in Galveston

Texas-New Mexico Power serves scattered areas including Galveston, Texas City and parts of North and West Texas. Its delivery charge is about $7.85 a month plus 6.47¢ per kWh, roughly $72.52 at 1,000 kWh. That's about 45% of a bill at the Texas average rate, and it's identical whichever provider you pick.

Of Texas's five main delivery utilities, TNMP is the most expensive at 1,000 kWh. A home in Galveston pays about $17.81 more a month in delivery than the same home in the CenterPoint area.

Providers can't mark delivery up, and it changes on March 1 and September 1 each year when the Public Utility Commission of Texas approves new rates.

Energy use in Gulf Coast

Hot, humid summers keep air conditioning running from May to October, so summer bills are often double spring bills. Hurricane season also makes a plan with good outage communication worth considering.

How to choose a plan in Galveston

Compare at your real usage. Plans are advertised at 1,000 kWh, but if your summer bills show 2,000 kWh, that's the price that matters.

Be careful with bill credits. A plan that's cheap at exactly 1,000 kWh can be expensive at 999 kWh or 1,500 kWh. Use the calculator above to check.

Prefer fixed rates. Variable plans can jump during heat waves and freezes. Check the contract length and early termination fee too.

Mark your contract end date. When a fixed plan ends, most providers move you to a pricier month-to-month rate.

Find your ESI ID

Your ESI ID identifies your meter. In TNMP territory it's 17 digits and starts with 1040051. It's printed on your bill near your service address.

Decode your ESI ID or check your current bill against the Texas average.
