Smart 1000 Select 12 by TXU Energy

Smart 1000 Select 12 is a 12 month fixed rate plan from TXU Energy. It often shows up near the top of PowerToChoose when you sort by price. That low advertised rate depends on a bill credit. If your usage fits the credit, the plan can be cheap. If it does not, you pay far more than the ad suggests. This page shows both outcomes with real numbers.

The advertised price

On PowerToChoose, Smart 1000 Select 12 shows 22.9 cents at 500 kWh, 10.9 cents at 1,000 kWh, and 15.5 cents at 2,000 kWh. Those are the three checkpoints every plan gets scored on. They are averages at exact usage levels, not a promise about your bill.

How the price is built

Energy rate14¢ per kWh
Base charge$9.95
Oncor deliveryPassed through
Bill credit$100
in any month you use 1,000 kWh or more
Summer bonus$25
more in July, August, and September, same 1,000 kWh rule

The key piece is the bill credit. This plan pays a $100 credit in any month you use 1,000 kWh or more. In July, August, and September the credit is $125. That credit is what makes the 1,000 kWh checkpoint look cheap. In a month below 1,000 kWh the credit vanishes, and your effective rate jumps.

Worked example

What a month costs: January as an example

The standard 1,000 kWh usage profile puts January at 1,010 kWh. Here is how Smart 1000 Select 12 prices that month in the Oncor area:

Energy charge$141.40
1,010 kWh × 14 cents
Base charge$9.95
Oncor delivery$65.87
$4.06 plus 1,010 kWh × 6.12 cents
Bill credit (used 1,000 kWh or more)
-$100.00
January total$117.22

That works out to 11.6 cents per kWh for the month. But notice how close the call was. January cleared the credit line by just 10 kWh. The bill lands at $213.19 and the real rate jumps to 21.5 cents.

Right at 1,000 kWh the cost per kWh drops sharply. One kWh less and the whole $100 credit is gone for that month. Most homes swing hundreds of kWh between seasons, so landing on the right side of that line every month is hard.

True cost

What it costs at real usage

At a 1,000 kWh monthly average with normal seasonal swings, here is the true annual cost by delivery area:

Delivery area
Oncor$2,007
16.7¢ true average · +53% versus advertised
CenterPoint$1,889
15.7¢ true average · +59% versus advertised
AEP Texas Central$2,011
16.8¢ true average · +54% versus advertised
AEP Texas North$2,243
18.7¢ true average · +45% versus advertised
TNMP$2,083
17.4¢ true average · +51% versus advertised

Your own months decide which side of the credit you land on. A single month under 1,000 kWh costs you the full $100.
