Peak Notifications

You can cut your electricity costs dramatically by reducing your use during periods of peak demand.

Saving energy now can save you money later.

4 Coincident Peak (4CP)

Our 4CP service gives you advance notice to reduce usage when demand peaks on the ERCOT system. All you need is an IDR meter, and you can save thousands of dollars in TDU charges.

This is a free service for TXU Energy customers. You can join at any time and participate in any 4CP event when you want.

How does 4CP work?

4CP intervals are determined by ERCOT based on the four highest 15-minute demand periods from June to September.
Once you opt in, you’ll get an email the day before and day of a forecasted 4CP event.
If you choose to curb your usage, you’ll save on future TDU charges, and those savings can add up.
Historically since 2012, 95% of 4CP intervals have occurred Monday - Friday between 4:00 p.m. and 5:00 p.m.
