Winterize. That’s the directive Gov. Greg Abbott gave to power companies and lawmakers Thursday when he called for a law and funding to better prepare Texas’ essential power infrastructure for the kind of extreme winter weather that created multiple crises this week.

Energy experts said that in some cases, retrofitting plants to withstand cold could be extremely difficult and expensive in Texas. Many of those plants already skimped on such upgrades due to the infrequency of prolonged and widespread subfreezing temperatures in the state. That’s despite a 2011 winter storm that also caused power outages.
