Normal Conditions

There is enough electric supply available to serve current demand on the grid. No action by consumers is needed.

ERCOT ENERGY EMERGENCY LEVELS

What is an energy emergency?

When electric supply and demand can’t be balanced with normal procedures, ERCOT will declare an energy emergency, which allows the grid operator to use resources only available during tight conditions. There are three energy emergency levels that are used to protect the reliability of the electric system and prevent an uncontrolled, system-wide outage.

Conservation Alert

ERCOT may call upon consumers to reduce electric use if there is a reliability risk to the electric system. Conservation tips, such as turning off lights and appliances, are available on the Public Utility Commission’s Power to Save Texas website. Simple actions can help balance generation supply and electric demand.

 


 

Energy Emergency Level 1

Conservation Critical; Risk of Controlled Outages 

When operating reserves drop below 2,300 MW and are not expected to recover within 30 minutes, ERCOT can call on all available power supplies, including power from other grids, if available.

Conservation is critical at this time. Tips can be found on the Public Utility Commission’s Power to Save Texas website.

 


 

Energy Emergency Level 2

Conservation Critical; Risk of Controlled Outages 

When operating reserves are less than 1,750 MW and are not expected to recover within 30 minutes, ERCOT can reduce demand on the system by interrupting power from large industrial customers who have contractually agreed to have their electricity turned off during an emergency. ERCOT can also use demand response resources that have been procured to address tight operating conditions.

Conservation is critical at this time. Tips can be found on the Public Utility Commission’s Power to Save Texas website.

 


 

Energy Emergency Level 3

Conservation Critical; Controlled Outages Underway 

When operating reserves drop below 1,000 MW and are not expected to recover within 30 minutes, ERCOT will order transmission companies to reduce demand on the electric system. This type of demand reduction is only used as a last resort to preserve the reliability of the electric system as a whole. Each utility is responsible for deciding how to decrease demand in their area.

This is typically done through rotating outages, which are controlled, temporary interruptions of electric service. In extreme circumstances, more prolonged outages may be required to balance supply and demand on the electric system.

Although utilities will be implementing outages in order to reduce demand, customers with electricity should continue to conserve. Conservation tips can be found on the Public Utility Commission’s Power to Save Texas website.
