One year later, Texans are wondering what has actually changed since Winter Storm Uri of 2021. Many asking whether or not “we fixed the grid.”
In 2021, the power outages in Texas were caused by a grid-wide mismatch of supply and demand – we simply did not have enough power being provided from generators to supply Texans with the electricity that they wanted and needed to use. Not only did we see that mismatch when the storm hit, but it was made worse by the fact that we had not predicted anything close to that. Traditional resources on the grid could not respond to the rapidly changing condition. Texas did last year and still does today face constant changes that make supply and demand of electricity difficult to predict: an increasing percentage of energy supply from renewable resources; an ever-growing demand for electricity, from new residents and new businesses; and changing weather patterns, with more frequent extreme weather events. With the conditions constantly changing, were we able to update our response to crisis since last February?
