Updated 10:55 a.m. Feb. 16 At about 10 a.m. Feb. 16, Montgomery County Judge Mark Keough posted a Facebook message with an update from CenterPoint Energy. Keough said because CenterPoint is within the ERCOT Texas Grid, it is required to "throttle back energy consumption" in its service territory because of demand elsewhere in the grid. CenterPoint is the only provider on the ERCOT grid in Montgomery County, he said. A total of 1 million CenterPoint customers were without power at the time of his post, Keough said. He said a timeline for full power restoration was not yet available.

As the second day of power outages dawns, CenterPoint Energy recorded 42.53% of customers had power as of 8:55 a.m., meaning more than half of its service area is still without power. This totals 1.38 million customers without power.

CenterPoint's last update on its Twitter page Feb. 15 stated as of 8 p.m., more than 1.4 million customers were without power, which included 1.27 million customers without power due to the request to reduce power and 141,500 customers without power due to other storm-related events.

The Electric Reliability Council of Texas—which manages the flow of electricity to about 90% of the state's electricity consumers—initiated rotating power outages across the state at 1:25 a.m., according to a Feb. 15 release from ERCOT. As such, CenterPoint Energy, which services large portions of the Greater Houston area, stated on Twitter early Feb. 15 that customers should conserve electricity and expect temporary power outages.

CenterPoint initially stated the temporary outages could last 15 minutes to more than an hour, but updated its statement on Twitter at 9:27 a.m. that customers currently experiencing outages should expect to be without power for at least the remainder of Monday.

CenterPoint stated customers still with power are asked to conserve power as much as possible to assist with stabilizing the state's power grid.

"We know this is a very difficult situation for our customers, but we are doing our part, based on [ERCOT's] directive, to reach a power supply and demand balance across the state," CenterPoint Energy stated on Twitter. CenterPoint's outage tracker was unavailable as of publication, but according to PowerOutage.US—a website that tracks the outages of electricity providers—more than 96,000 CenterPoint customers were without power as of 9:29 a.m. Feb. 15.
