With a week to go in the legislative session, the Texas House on Sunday gave preliminary approval to a sweeping bill aimed at shoring up the state’s electric supply system and infrastructure, a proposal crafted in response to statewide power outages in February amid deadly winter storms that plunged millions of Texans into cold and darkness for days. Senate Bill 3 would require certain infrastructure upgrades to prepare for extreme weather, seek to improve oversight of the state’s electricity supply chain and create a statewide emergency alert system in the event of power outages in the future. “We all know exactly what this bill is,” said Rep. Chris Paddie, R-Marshall, author of the House version of the reform measure, which he said targets “the systematic failures from wellhead to light switch to try to address three main buckets: oversight and accountability, communication failures, which we saw throughout the system, and weatherization.”
