SAN ANTONIO – The CPS Energy Board of Trustees met on Monday afternoon, nearly one week after an explosion on the North Side hospitalized five people.
But six days later, the utility is still tight-lipped on what happened, pointing to the National Transportation Safety Board’s ongoing investigation.
The two separate explosions took place around 6 p.m. on April 21 in the 15000 block of Preston Hollow Drive, which is located near Thousand Oaks Drive.
Two adults and one child suffered burns and were hospitalized after the first explosion. Two additional adults were hospitalized as a result of the second explosion.
A Brooke Army Medical Center spokesperson said that, as of Monday, two of the victims are still in critical condition. The other victims’ conditions have since improved or were in “good” shape to begin with.
KSAT has repeatedly requested information about the explosions and what led up to them, but CPS Energy has mostly kept to updates on support and relief efforts for residents.
KSAT approached CPS Energy President and CEO Rudy Garza ahead of Monday’s meeting, but he said he could not answer our questions.
“The comments I make today are all the comments I’m going to have on this topic,” he said.

During remarks at the beginning of the meeting, Garza focused on acknowledging the victims, thanking CPS Energy crews and local officials, and highlighting the utility’s response to the explosions.
Though he encouraged people to call CPS Energy if they ever smell gas, Garza provided no specific information on what had led to the explosions.
“In this particular instance, the National Transportation Safety Board is involved and is leading the investigation. And even these comments that we make today have to be approved as part of that investigation process,” Garza said. “So we are doing everything we can to be cooperative with the NTSB as part of this process. Updates on this investigation will come from the NTSB.”
“We are trying to update the community with information that we’re allowed to update as there are changes in circumstances,” Garza continued. “So we will continue to update the community as we can and are able. But all of those communications are approved through our federal regulator, in this case who’s leading the investigation."
In a statement to KSAT on Sunday, CPS Energy said its Customer Response Unit and gas team members are helping customers relight gas pilot lights and answer questions about natural gas service upon request.
CPS Energy said if any customers at any point smell gas, leave the house immediately and call CPS Energy at 210-353-HELP (4357) or 911.
