"Those Who Do Not Learn History Are Doomed To Repeat It."


Federal Energy Regulatory Commission (FERC) has published its final report on the Texas 2021 power outages. According to FERC during the last 10 years, there have been four extreme cold weather events which have threatened the Texas power grid. That includes the 2011 Texas power outage during which hundreds of people died.

As found after past weather events, investigators determined that most of the power outages could have been avoided if power plants and wind turbines had been better protected against the cold and ice.

Eighty-one percent of freeze-related generating unit outages occurred at temperatures above the units' stated ambient design temperature.

Eighty-seven percent of unplanned generation outages were due to fuel issues related to natural gas.

Natural gas fuel supply issues were caused by natural gas production declines.



Some recommendations by FERC include:

Generator owners should retrofit existing generating units, and when building new units account for weather events including extreme temperatures.

Generator owners and operators should perform annual training on winterization plans.

Develop corrective action plans should freeze-related outages occur.


However, Texas maintains its electric grid as an isolated island, and hasn't followed past recommendations to avoid electric grid outages.
