Could Texas Grid Collapse Happen Here? ICC Initiates Notice of Inquiry

Back on Feb. 14, Texas’ power grid was 4 minutes, 37 seconds away from collapsing — an event that could have had catastrophic repercussions, not just to Texas but to the U.S. and world economy.

In the throes of an extreme cold weather event, rolling blackouts swept Texas and other southern states, leaving millions without electricity or heat, sending natural gas prices skyrocketing to record levels and spurring an angry Texas legislature to order a study of what went wrong.

Now, the Illinois Commerce Commission is launching its own investigation, opening a Notice of Inquiry into Extreme Weather Preparedness to ensure Illinois consumers are protected.

“What happened in Texas, Louisiana and Oklahoma this past winter is extremely concerning to the commission,” said ICC Chairman Carrie Zalewski. “While we regularly hear from the utilities and regional transmission organizations about their winter and summer preparedness efforts, we are digging deeper so that we are absolutely certain that every reasonable step possible is being taken to protect Illinois consumers from widespread outages and extreme energy prices.”

In mid-February of this year, a severe winter storm that blanketed the south-central region of the United States forced natural gas processing plants and compressor stations to shut down or perform maintenance as liquid froze inside pipes and compressors, dramatically reducing output in the region.

The reduction in supply coupled with an increase demand for home heating by gas-fired electric generators sent natural gas prices soaring from approximately $3.50 per MMBtu on Feb. 10, 2021 to nearly $24 per MMBtu on Feb. 17, 2021.

Price increases for natural gas delivered to Illinois by pipelines from the south-central region were even more dramatic hitting as high as $255 per MMBtu during this period.

The electric sector in the south-central region was also impacted by the winter storms. According to the U.S. Department of Energy, on the morning of Feb. 16, 2021 there were approximately 4.89 million power outages across Texas, Louisiana, and Oklahoma.

Real-time wholesale electric market prices at the Electric Reliability Council of Texas were reportedly more than $9,000 per megawatt hour on the morning of Feb. 15, 2021 compared with less than $50 per megawatt hour prior to the winter storm.

“We know from past experience that extreme weather events are going to happen here in Illinois, and they can be devastating,” ICC Commissioner Michael T. Carrigan said. “Through the NOI, we are seeking highly detailed information from utility service providers and operators about their response efforts and communication plans to ensure that they are adequately prepared and equipped to handle a weather related crisis with minimal impact on  consumers.”

The 21-NOI-01 directs questions to natural gas, electric, water and sewer utilities in Illinois, independent system operators or regional transmission operators, owners or operators of electric generation and natural gas pipelines located in Illinois, and to all interested parties.

The NOI schedule requires the submission of initial comments by June 14, 2021, and submission of reply comments by July 30, 2021. However, the NOI manager is authorized to schedule further rounds of comments if she believes that additional comments would be helpful and may alter the schedule if necessary.

The NOI manager is Joy Nicdao-Cuyugan.

Respondents must submit an original and three copies of all comments, reply comments, and other documents to the Office of the Chief Clerk of the Commission. Interested persons and entities are also requested to email the same in electronic form (preferably Adobe pdf) to

The NOI manager will take steps to ensure that copies of all documents filed in the proceeding are posted to the Commission’s website Copies of all documents filed in the proceeding will be available for public inspection at the Office of the Chief Clerk of the Commission in Springfield and the Commission’s Chicago office.

A Notice of Inquiry proceeding is not a rulemaking action, and the information gathered may or may not form the basis for the initiation of rulemaking or other purposes.
