Wikipedia cites https://slate.com/news-and-politics/2003/08/why-texas-has-it... and says it’s political.

For what I read about Texas, the root if the problem is that they opted to disconnect from the interstate grid, IIRC to avoid Federal regulations. If anything goes bad, they can't lean on neighbor states to provide, so they blackout.

The intermittency of renewables was not what happened to Texas. Texas made a conscious choice to build their own isolated grid. Then they failed to invest in winterization of their grid sufficiently. The rolling blackouts were caused by gas turbine plants going offline, though the intermittency of solar and wind in Texas didn't help.

Texas recently shut down their power grid when it got cold out because it was cheaper than weatherproofing or suffering the regulations to interconnect with other neighbouring states.

What a horrible article. First, Texas has its own independent grid as a matter of physics. Electricty travels at the speed of light so a continuous grid from coast to coast would get out of sync on phases just by travel distance. Texas just happens to be physically in the middle and large enough to have trouble by being supplied by either east or west grid. Second, ERCOT manages when utilizes can take assets out of commission to do maintenance. Texas peak demand is in the summer so if you ha

Texas resident here w/ no connection to the power industry, but I'm not sure I would call it a failure of our grid. Texas is the largest producer of energy in the United States in fossil fuels, wind, and solar. We are the only state to have our own grid[0] and we have an open electric market with competition for consumer and business electric generation.The dependence on wind turned out to be a vulnerability with ice (something I didn't know until recently) and the lack of high

Texas has its own grid so that is not subject to federal regulation. blame ercot
