Help PEC lower your costs
Transmission cost

Over the past six years, the transmission cost has risen more than 90 percent across Texas. These transmission costs account for 10 percent of PEC’s annual budget, equaling about $61 million for 2016.

PEC members will find the Transmission Cost of Service in the account summary portion of their PEC bill (example).

If we’re able to reduce our peak demand during four key days this summer with the help of our members, PEC can save substantially and pass those savings on to you.

Transmission costs4CP basics
Four Coincidental Peaks (4CP) is a value measured by all regulated utilities and cooperatives in Texas to help capture transmission costs from end users. The 4CP is defined by the average of four peak events occurring in June, July, August and September, usually between the hours of 2 and 6 p.m.

Peak hours generally occur between 3 and 7 p.m.Why are these four peak events important to me?
The 4CP determines transmission costs for the following year. By reducing energy use during the four peak summer events, PEC members can reap savings for an entire 12 months! A simple 1 percent reduction would mean $1.2 million in savings for PEC members.

When PEC identifies a potential peak day, we will notify members by email and ask that they reduce energy use during key hours.

PEC appreciates your active participation in helping manage peak demand and transmission costs. To learn more about our savings and conservation programs, including free energy audits, visit pec.coop/conservation.

Help PEC lower transmission demand eventsHow you can help
In preparation for the 4CP events, members can proactively reduce their energy consumption by following these tips:

  • Turn off unnecessary lights, appliances and electronic equipment.
  • When at home, close blinds and drapes that get direct sun, set air conditioning thermostats to 78 degrees or higher, and use fans in occupied rooms to feel cooler.
  • When away from home, set air conditioning thermostats to 85 degrees and turn all fans off before you leave. Block the sun by closing blinds or drapes on windows that get direct sun.
  • Do not use your dishwasher, laundry equipment, hair dryers, coffee makers or other home appliances during the peak hours of 2 to 6 p.m.
  • Avoid opening refrigerators or freezers more than necessary.
  • Use microwaves instead of an electric range or oven.
  • Set your pool pump to run in the early morning or evening instead of the afternoon.
