UPDATE AS OF MONDAY, FEBRUARY 15, 2021, 2:55 AM POWER EMERGENCY – CONSERVATION CRITICAL ROTATING OUTAGES HAVE BEGUN ERCOT, Grid Operator, issues Power Emergency across the state of Texas.

San Antonio, Texas – February 15, 2021 – The Electric Reliability Council of Texas (ERCOT) has instructed utilities to begin to shed load causing rotating managed outages because there is not enough electric generation available across the state to keep up with customer demand throughout the system.  As part of our participation in ERCOT and the critical nature of this stage, we are required to participate in coordinated rotating outages in an effort to prevent larger and more extreme impacts on the Texas grid. CPS Energy is also asking natural gas customers to reduce energy use as well.

“Rotating outages are necessary to help preserve the integrity of the Texas electric grid,” said Rudy Garza, Chief Customer Engagement Officer for CPS Energy.  “It is crucial that we, along with other Texas utilities, implement rotating outages as directed by ERCOT. The mandatory request for load shed can be subsidized by residential and commercial customers doing what they can to reduce energy use.”

Consumers can monitor real-time grid conditions by downloading the ERCOT mobile app and/or following the grid operator on Twitter (@ERCOT_ISO). Customers are also encouraged to follow CPS Energy’s social media feeds (@cpsenergy) and to share the utility’s messaging with their family and friends. Rotating outages are controlled, temporary interruptions of electrical service initiated by each utility when supplies of reserve power are exhausted. Without this safety valve, generators would overload and begin shutting down to avoid damage, risking a domino effect of widespread, uncontrolled outages. The outages are limited to 10 to 15 minutes before being rotated to a different neighborhood.

Some customers may experience longer outages if power surges cause equipment failure during the restoration process. Customers can minimize power surges by turning off appliances, lights and other equipment, except for one light to determine when power has been restored.

Critical need customers such as hospitals and nursing homes are generally not included.

It is not known at this time how long the need for rotating outages will last.

Extreme temperatures have caused stress on the grid with higher than average consumption for this time of year. Consumers and businesses should reduce their electricity use to the lowest level possible.

CPS Energy is asking to continue to reduce electricity use by:

  • Turn down thermostats to 68 degrees or lower.
  • Open blinds and shades to take advantage of the sun’s natural heat during the day.
  • Close shades and blinds at night to reduce the amount of heat lost through windows.
  • Turn off and unplug nonessential lights and appliances.
  • Avoid using large appliances (i.e., ovens, washing machines, etc.).
  • Businesses should minimize the use of electric lighting and electricity-consuming equipment as much as possible.

A “Power Emergency” indicates that ERCOT has instructed utilities to implement rotating outages to reduce load.

Rotating outages are controlled, temporary interruptions of electrical service initiated by each utility when supplies of reserve power are exhausted. Without this safety valve, generators would overload and begin shutting down to avoid damage, risking a domino effect of a widespread, uncontrolled outage.

The outages are typically limited to 10 to 15 minutes before being rotated to a different neighborhood. Some customers may experience longer outages if power surges cause equipment failure during the restoration process. Customers can minimize power surges by turning off appliances, lights and other equipment, except for one light to determine when power has been restored.
