UPDATE: February 19 8:40 A.M.
The Electric Reliability Council of Texas (ERCOT) expects to come out of emergency conditions later this morning.
Senior Director of System Operations Dan Woodfin said, “there is enough generation on the electric system to allow us to begin to return to more normal operating conditions.”
No additional outages were needed overnight to keep power supply and electric demand in balance, and only a few generating units tripped. Customers should contact their electric provider if they are without power.
Customers that are without power likely fall into one of these three categories:
- Areas out due to ice storm damage on the distribution system
- Areas that were taken out of service due to the energy emergency load shed that need to be restored manually (i.e., sending a crew to the location to reenergize the line)
- Large industrial facilities that voluntarily went offline to help during this energy emergency
As of 7:30 this morning, approximately 34,000 MW of generation remains on forced outage due to this winter weather event. Of that, nearly 20,000 MW is thermal generation and the rest is wind and solar.
UPDATE: February 19 6 A.M.
As of 6:00 a.m., there are approximately 27,000 remaining outages. At the peak of the ERCOT directed load shed, more than 1.3 million customers were left without power.
Oncor continued working to restore power to more than 19,000 customers who were impacted by an ice storm that blanketed Palestine, Lufkin and Nacogdoches with 72,000 outages remaining.
Oncor expects the majority of storm restoration to be complete in these areas by early Sunday.
If you are still without power, please report your outage by calling 888-313-4747, texting OUT to 66267, using the MyOncor app or visiting Oncor.com.
Because generation supply remained stable, ERCOT did not issue any controlled or rotating outages on Thursday – the first full day without a load-shed event since early Monday.

UPDATE: Feb. 18, 6:20 a.m.
Yesterday, ERCOT directed Oncor and other utilities to begin restoring power previously dropped from the electric grid. As a result of the increased generation and stable demand, Oncor has since been able to cease controlled, or rotating, outages.
As of 5:30 a.m. this morning, there are approximately 150,000 remaining Oncor customers without power.

UPDATE: 9:15 a.m
ERCOT officials announced there will continue to be controlled outages as there is still a lack of available generation.
As power demand lowered overnight, Oncor was able to restore previously dropped power load and increase the capability to rotate some outages.
However, many customers continue to experience extended outages.
UPDATE: 3:30 p.m
#LIVE: ERCOT officials are providing an operational update on their response during this winter weather event.
ERCOT has directed local utilities to restore 400,000 households in the last hour.
Generation availability is improving.

As the Texas power system faces an unprecedented amount of electric generation, the Electric Reliability Council of Texas (ERCOT) requested ONCOR and utilities across the state to implement controlled power outages to protect the electric grid.
The length of these controlled outages was significantly extended due to emergency grid operations.
The outages are taking place across the service territory and ERCOT has said they could be required through Tuesday.
Customers do not need to report outages at this time as crews continue to make repairs from the storm.
Oncor had this to add, "We are doing everything possible to respond to each of these power emergency events. We remain in close coordination with ERCOT and we appreciate everyone’s patience as we protect the integrity of the Texas grid."
Oncor added that with the combination of lack of generation and winter storm damage estimated restoration times are not yet known.
