The Electric Reliability Council of Texas

ERCOT oversees more than 90% of Texas' power load.

What is the Electric Reliability Council of Texas?

The Electric Reliability Council of Texas or ERCOT is responsible for monitoring the flow of electric power to more than 26 million Texas consumers, including those served by Central Texas Electric Co-op.  ERCOT manages the state's power grid and takes steps to ensure the power supply meets consumer demand. 

Frequently Asked Questions About ERCOT

Forced outages are load shed events controlled by ERCOT to reduce the demand of electricity on the power grid. They may also be referred to as blackouts, rolling blackouts, or controlled outages. Load shed events occur when the demand for electricity exceeds the power supply available and voluntary conservation efforts were not enough to reduce the strain on the electric grid. ERCOT will require forced outages on electric consumers to reduce the demand of electricity to maintain the integrity of the electric grid.

When forced outages (load shed events) occur, Central Texas Electric Co-op must comply with the load shed procedures as instructed by ERCOT.  Central Texas Electric Co-op does not control if, when, or how long the load shed event will last.  Central Texas Electric Co-op gets little to no warning when load shed events will occur. 

When the electric supply provided by all available power generation is not enough to meet customer demand for power, ERCOT begins emergency operations. During an ERCOT energy emergency, when there is not enough generation to meet consumer demand for power, and all other operational tools have been exhausted, power demand must be lowered to avoid uncontrolled blackouts.

Before every summer and winter, ERCOT forecasts potential electricity demand and capacity. If it appears that demand will exceed supply, ERCOT will initiate its Energy Emergency Alert (EEA) system. Alerts range from calls for conservation to a declaration of a statewide power emergency that could result in controlled outages—controlled, planned service interruptions designed to ensure grid stability. 

 

Here is a summary of ERCOT's EEA system:

ERCOT grid conditions are normal.

 

2021_img_ERCOT-GridConservationAlert_HelpCenter.jpg

Conservation Alert: ERCOT may ask consumers to conserve power by adjusting their thermostats and limiting the use of appliances.

 

2021_img_ERCOT-EEA1-ConservationNeeded_HelpCenter.jpg

Energy Emergency Level 1: Conservation is needed. ERCOT operators have the authority to call on all available power supplies, including power from other grids, if available.

 

2021_img_ERCOT-EEA2-ConservationCritical_HelpCenter.jpg

Energy Emergency Level 2: Conservation is critical. Operators drop large commercial/industrial load resources that have entered contracts agreeing to be interrupted during an emergency.

 

2021_img_ERCOT-EEA3-ControlledOutages_HelpCenter.jpg

Energy Emergency Level 3: Controlled Outages in Progress. ERCOT requires controlled outages to reduce demand and ensure the state electric grid's stability. These controlled outages typically last 30 to 60 minutes per rotation.

 

 

As always, Central Texas Electric Co-op will monitor ERCOT grid conditions and conservation requests or energy emergencies. If emergency requests that involve forced outages for consumers are made by ERCOT, Central Texas Electric Co-op will comply with those as required and will send notifications as quickly as humanly possible*. Please ensure the contact information on your account are correct. You can do that here.

You are also encouraged to sign up to receive push notifications directly from ERCOT. You can do this by downloading the ERCOT app (Google Play or App Store) and enable push notifications for alerts.

*Please note: Notices are sent out as quickly as humanly possible, but the situation on the grid can change very quickly. If ERCOT's reserve margins reach critical condition and ERCOT calls for load shed, the outages may begin before all notifications are able to be sent out and phone line may become overwhelmed. 

During load shed events, we are unable to tell you when you will be without power, how long the forced outages will last or when power will be restored since those answers depend on many factors outside of Central Texas Electric Co-op's control.  We will share the most current information we have received from ERCOT.

 

  • Members must be prepared for a possible power outage without advance warning. As much as possible, all efforts will be made to provide advance notification of ERCOT-mandated load shedding, but there can be circumstances where such a notification isn’t possible.
  • Members designated as critical load are not guaranteed an uninterrupted supply of electricity. It is the member's responsibility to arrange for alternative electric power sources in the event of any outage, including ERCOT load-shedding events.
  • Members who depend on electric-powered medical equipment or those designated as critical care or chronic condition with CTEC are not guaranteed an uninterrupted, regular or continuous power supply. It is the member’s responsibility to arrange for alternative electric power sources in the event of any outage, including ERCOT load-shedding events.
  • Load shedding is a mandatory emergency order from ERCOT based on the available generation and consumer demand. During load-shedding events, CTEC’s ERCOT transmission operator, the Lower Colorado River Authority Transmission Services Corp., is obligated to immediately implement load-shedding procedures. CTEC likely will not have sufficient information to notify members if or when they may lose power or how long the load-shedding event may last.
  • In an extreme emergency, ERCOT may require electric utilities to shed large amounts of load over long periods of time. These outages are critical for ensuring the integrity of the state’s electric grid and preventing an uncontrolled system-wide blackout, which could last significantly longer than a load-shedding event.
  •  CTEC, like all electric utilities in ERCOT’s service area, is required to comply with all ERCOT directions for shedding load until ERCOT ends the energy emergency.

 

Please help by conserving electricity in any way you can. This is important as long as ERCOT forced outages are in place.

Spring and Summer Conservation Tips:

  • Turn up your thermostat 2-3 degrees from 3 to 7 p.m.; Adjust the thermostat even higher if no one will be home during the day.

  • If home, use fans to feel 4-6 degrees cooler. Turn the fans off if no one is in the room.

  • Set pool pumps to run early morning or overnight; program them to shut off from 3 to 7 p.m., since these are typically peak hours for summer months.

  • Turn off and unplug non-essential lights and appliances.

  • Avoid using large appliances, especially during peak hours.

  • Businesses should minimize the use of electric lighting and electricity-consuming equipment as much as possible.

  • Large consumers of electricity should consider shutting down or reducing non-essential production processes.

 

Winter Conservation Tips:

  • Turn down your thermostat to 68° in the daytime and 55° at night or when you're away from home.

  • When at home, open blinds and shades during sunny days to take advantage of the sun's natural heat.

  • Close shades and blinds at night to reduce the amount of heat lost through windows.

  • Turn off and unplug non-essential lights and appliances.

  • Avoid using large appliances.

  • Businesses should minimize the use of electric lighting and electricity-consuming equipment as much as possible.

  • Large consumers of electricity should consider shutting down or reducing non-essential production processes.

If someone in your home depends on an electrically operated health aid, sign up for Central Texas Electric Co-op's Medical Necessity Program. Please note, Central Texas Electric Co-op's Life Support Registry does not guarantee there will be no power interruptions. Power outages happen for many reasons that may be out of the cooperative's control. It is recommended for members on the Life Support Registry to ensure they have secondary power or a back up plan in the event of prolonged outages.

REVISED: ERCOT Issues Conservation Appeal to Texans and Businesses

REVISED TO ADJUST TIMES FOR CONSERVATION APPEAL.

Appeal Effective Wednesday, July 13, 2022

AUSTIN, TX, July 13, 2022 – As extreme hot weather continues driving record power demand across Texas, the Electric Reliability Council of Texas (ERCOT) is issuing a Conservation Appeal for Wednesday, July 13 between 2-9 p.m. ERCOT is asking Texans and businesses to voluntarily conserve electricity during this time. Currently, no system-wide outages are expected.

Today’s conditions are expected to be similar to those experienced on Monday, July 11, 2022. On that day, Texans and businesses responded by voluntarily conserving electricity and helping ERCOT successfully meet record power demand by reducing their energy use by 500 MWs.

Conservation is a reliability tool ERCOT has deployed more than four dozen times since 2008 to successfully manage grid operations. This notification is issued when projected reserves may fall below 2300 MW for 30 minutes or more.

ERCOT encourages all electric customers to visit the Public Utility Commission’s (PUC) Power to Save or their electric provider’s websites to get important conservation tips. According to the PUC, ways to reduce electricity use during peak times include turning up your thermostat a degree or two, if comfortable, and postponing running major appliances or pool pumps during the requested timeframe.

ERCOT continues to use all tools available to manage the grid effectively and reliably, including using reserve power and calling upon large electric customers who have volunteered to lower their energy use.

ERCOT emphasizes that the call for conservation is limited to the hours of 2-9 p.m. on Wednesday, July 13.

Factors driving the need for this important action by customers:

Record high electric demand. The heat wave that has settled on Texas and much of the central United States is driving increased electric use. Other grid operators are operating under similar conservative operations programs as ERCOT due to the heatwave.
Low wind. Wind generation is currently generating less than what is historically generated in this time period.
Forced thermal outages. The number of forced outages in thermal generation exceeds ERCOT forecasts.
Solar. Developing cloud cover in West Texas has reduced the amount of solar generation.

Under current projected scenarios, performance of the generation fleet Wednesday is:





Installed Capacity
Dispatchable - 80,083
Wind - 35,162
Solar - 11,787


Wednesday (7/13) Tightest Hour (3-4 p.m.)
Dispatchable - 67,076
Wind - 4,294
Solar - 7,987


Percentage of Installed Capacity Available at Tightest Hour
Dispatchable - 84%
Wind - 12%
Solar - 68%


Note: Total forecasted demand is 78,451 MW.

Statement by Electric Reliability Council of Texas Interim CEO, Brad Jones on current grid conditions

AUSTIN, TX, May. 13, 2022 - With unseasonably hot weather driving record demand across Texas, ERCOT continues to work closely with the power industry to make sure Texans have the power they need. This afternoon, six power generation facilities tripped offline resulting in the loss of approximately 2,900 MW of electricity. At this time, all generation resources available are operating. We’re asking Texans to conserve power when they can by setting their thermostats to 78-degrees or above and avoiding the usage of large appliances (such as dishwashers, washers and dryers) during peak hours between 3 p.m. and 8 p.m. through the weekend.

Resource: Thermal Performance: (% of installed as of 4:00 p.m.) 50,703 (66%)

Resource: Wind Performance: (% of installed as of 4:00 p.m.) 5,859 (17%)

Resource: Solar Performance: (% of installed as of 4:00 p.m.) 8,333 (73%)

ERCOT Issues Winter Weather Watch Through Sun., Feb. 6

Texans reminded to contact local utilities for power outage issues

AUSTIN, TX, Feb. 2, 2022 — The Electric Reliability Council of Texas (ERCOT) has issued a Watch effective through Sunday, Feb. 6 as winter weather moves into Texas. ERCOT is forecasting high energy demand for the duration of the winter weather. This cold front will bring freezing temperatures and precipitation to the ERCOT region. ERCOT is taking action ahead of the expected increase in demand to ensure grid reliability. On Friday, Jan. 28, ERCOT issued an Operating Condition Notice (OCN) to the electricity market for extreme winter weather. ERCOT projects to have sufficient generation to meet the high demand for electricity.

“ERCOT is using all the tools available to manage the grid effectively during this winter weather,” said Interim CEO Brad Jones. “ERCOT will deploy all the resources and aggressively implement the tools available to us to manage the grid reliably during this winter weather. We will continue coordinating closely with the Texas Division of Emergency Management, the Public Utility Commission, the Railroad Commission and elected officials — as well as electric generators and transmission and distribution utilities — to keep Texans informed throughout the week.”

ERCOT has implemented many reforms to increase the reliability of the Texas grid:

- Inspected generating units and transmission and distribution facilities for weatherization to comply with new PUC requirements. ERCOT has inspected hundreds of electric generation units and transmission facilities and found only 3 with any deficiencies.
- Requiring CEO attestations of weather readiness. A rule change implemented last year requires all market participants who own or operate generation resources and/or transmission/distribution power lines to submit a letter signed by their CEO twice a year certifying their companies have completed their weatherization preparations to protect the electric grid for the summer and winter seasons.
- Taking a more conservative approach to operating the grid. ERCOT’s grid management is at its most aggressive since the market was created two decades ago. ERCOT is increasing operational reserves to ensure adequate generation is available to Texas homes and businesses and is bringing more generation online sooner if it is needed to balance supply and demand. The grid operator is also purchasing more reserve power, especially on days when the weather forecast is uncertain.
- Assessing on-site fuel supplies. ERCOT has assessed the on-site fuel supply for some gas-fired generators.
- Performing unannounced testing of generation resources. This testing helps verify that generators have provided accurate information about their availability.

“While grid conditions remain strong with enough capacity, our weather forecasts show there is potential for significant frozen precipitation behind this week’s cold front,” said Jones. “With frozen precipitation there is always a chance for local outages caused by things like ice on wires or fallen tree limbs. These local outages are not related to the amount of available electricity generated and put on the grid. Texans should contact their utility in the event they experience a localized outage.”

Final Winterization Report: Texas Grid Ready for Winter Weather Operations

AUSTIN, TX, Jan. 18, 2022 – The Electric Reliability Council of Texas (ERCOT) today filed its final winter weatherization readiness report of the season with the Public Utility Commission of Texas. The report shows 321 out of 324 electric generation units and transmission facilities fully passed inspection for new winterization regulations from the Commission.

“The Texas electric grid is more prepared for winter operations than ever before,” said Interim ERCOT CEO Brad Jones.

ERCOT conducted onsite inspections at 302 electric generation units during December, representing 85 percent of the megawatt hours lost during Winter Storm Uri due to outages and 22 transmission station facilities. Three resources have been identified for further review but remain operational. They represent approximately 0.4 percent of the total ERCOT generation fleet.

“We are confident these 321 inspected facilities either meet or go beyond the new requirements from the Commission and we will continue to work with the other 3 facilities to ensure they correct remaining deficiencies,” said Woody Rickerson, ERCOT Vice President of System Planning and Weatherization. “Our teams spent thousands of hours preparing for and conducting these 324 on-site inspections to ensure the electric grid is prepared for winter.”

Results as of January 17, 2022: 324 ERCOT On-Site Inspections at 302 Generation Facilities and 22 Transmission Facilities

Generation Units, all deficiencies cleared - 299

Generation Units with remaining deficiencies - 3

Transmission Facilities, all deficiencies cleared - 22

Transmission Facilities with remaining deficiencies - 0


The Commission will determine any potential enforcement actions resulting from the inspections. Last year, the Texas Legislature increased the maximum penalties for violating weatherization rules to $1,000,000 per day per violation.

Electric Generation Fleet Ready for Winter Weather Following ERCOT On-site Winterization Inspections

AUSTIN, TX, Dec. 30, 2021 - The Electric Reliability Council of Texas (ERCOT) has completed on-site inspections of mandatory winterization efforts, and inspection results show the independently-owned electric generation fleet and electric transmission companies serving the ERCOT region are ready for winter weather. Inspections were completed at more than 300 electric generation units, representing 85 percent of the megawatt hours lost during Winter Storm Uri due to outages and 22 transmission station facilities.

ERCOT has filed a preliminary summary inspection report with the Public Utility Commission of Texas and will submit its final inspection report on January 18, 2022 for review and any potential enforcement action. Earlier this year the Legislature increased the maximum penalties for violating weatherization rules to $1,000,000 per day per violation.

“Texans can be confident the electric generation fleet and the grid are winterized and ready to provide power,” said Woody Rickerson, Vice President of Grid Planning and Weatherization. “New regulations require all electric generation and transmission owners to make significant winterization improvements and our inspections confirm they are prepared.”

ERCOT does not own or operate any electric generation units or electric power lines. ERCOT, however, is responsible for balancing electric supply and demand on an electric grid that serves more than 26 million Texans representing about 90 percent of the state’s electric demand.

Of 302 generation resources inspected, some generators had exceeded PUC winterization requirements. Only ten generation resources inspected had items identified on the day of inspection requiring correction. For example, a generation unit may have needed a windscreen to be compliant, but it was not yet installed on the day of inspection. Many items like this have now been completed since the inspection occurred and all ten units are still operational. The ten generation units have a total capacity of 2,129 megawatts, representing about 1.7 percent of the total ERCOT generation fleet.

Of the 22 transmission station facilities inspected, ERCOT found that six had potential identified deficiencies, most of which have already been corrected. These were generally minor items, such as cabinet heaters out of service or missing weather stripping on cabinet doors on the day of inspection. Most of these items have already been corrected.

ERCOT will conduct follow-up inspections on the generation and transmission facilities with potential identified issues. ERCOT and its contractors have spent more than 3,600 hours on these inspection-related activities to date. Additionally, ERCOT and PUC staff are actively monitoring the compliance plans of the generation resources that requested additional time to finalize compliance with the new winterization regulations.
