How to choose the best StarTex energy plan for you
Picking the wrong StarTex Power energy plan without knowing your home’s energy usage can cost you hundreds or thousands of dollars.
The #1 most important thing: Know your usage!
The key to avoid overpaying is knowing your expected usage and comparing monthly costs for each plan based on that usage amount.
With things like gasoline, the “price per gallon” you see on the sign is the price you pay no matter how many gallons you pump.
$3 per gallon. Pump 10 gallons, pay $30. Simple.
Electricity in Texas is not as simple as buying gasoline. The advertised “price per kWh” is based on a specific, exact monthly usage (usually 2000 kWh).
And, each plan has a different calculation for how your monthly bill is determined.
Your effective “price per kWh” can only be determined by calculating your monthly bill, then dividing that monthly bill by your usage.
Advertised “price per kWh” can be misleading because it’s based on a specific usage like 2000 kWh. It’s best to shop based on the total bill for your home’s expected usage.
How do you do that when the math is complex, and every plan is a little different?
ComparePower has already done all this complicated math for you.
First, we help you determine your expected monthly kWh usage. Then we show you the plans and their total monthly cost for your usage.
