evidence: Beto O’Rourke said Texas was warned for years about power grid [...] We found that O’Rourke spoke accurately — there had been years of warnings by energy experts about the state’s power system following cold weather in February 2011, when around 200 generating units faltered, causing power outages for 3.2 million customers, according to a post-mortem of that crisis. [...] Experts have been warning about the failures of the state’s power grid for years, particularly after a 2011 cold spell. The Federal Energy Regulatory Commission and the North American Electric Reliability Corp. wrote an extensive report showing that recommendations following a 1989 outage weren’t implemented. Other experts have also warned for years about ERCOT and power blackouts, and state legislators tried to propose bills to improve the state’s energy infrastructure.
