Cristian Pineda's mother found him dead in their freezing mobile home.
Maria Pineda found her son unresponsive the next day and called 911 while attempting CPR, according to the lawsuit.
"Our thoughts are with all Texans who have and are suffering due to this past week," the ERCOT statement continued. But the lawsuit -- filed on behalf of Maria Pineda and the estate of Cristian Pineda by attorney Anthony Buzbee -- contends that power was turned off for"those who were most vulnerable to the cold."
"The blackouts instead lasted days. The failure to adequately inform Plaintiffs of the length of the blackouts prevented them from properly preparing for the lack of power, or leaving the area. Accurate information might have saved Cristian Pineda's young life," the lawsuit alleged. The lawsuit also noted that following a severe winter storm in 2011, the Federal Energy Regulatory Commission and the North American Electric Reliability Corporation issued a report informing ERCOT that"additional winterizing of the power infrastructure in Texas was necessary."
