The Texas Tribune reports:

Millions of Texans have gone days without power or heat in subfreezing temperatures brought on by snow and ice storms. Limited regulations on companies that generate power and a history of isolating Texas from federal oversight help explain the crisis, energy and policy experts told The Texas Tribune.

While Texas Republicans were quick to pounce on renewable energy and to blame frozen wind turbines, the natural gas, nuclear and coal plants that provide most of the state’s energy also struggled to operate during the storm. Officials with the Electric Reliability Council of Texas, the energy grid operator for most of the state, said that the state’s power system was simply no match for the deep freeze.

“Nuclear units, gas units, wind turbines, even solar, in different ways — the very cold weather and snow has impacted every type of generator,” said Dan Woodfin, a senior director at ERCOT.

Energy and policy experts said Texas’ decision not to require equipment upgrades to better withstand extreme winter temperatures, and choice to operate mostly isolated from other grids in the U.S. left power system unprepared for the winter crisis.

Policy observers blamed the power system failure on the legislators and state agencies who they say did not properly heed the warnings of previous storms or account for more extreme weather events warned of by climate scientists. Instead, Texas prioritized the free market. [Continue reading…]

Texas’ power grid was “seconds and minutes” away from a catastrophic failure that could have left Texans in the dark for months, officials with the entity that operates the grid said Thursday.

As millions of customers throughout the state begin to have power restored after days of massive blackouts, officials with the Electric Reliability Council of Texas, or ERCOT, which operates the power grid that covers most of the state, said Texas was dangerously close to a worst-case scenario: uncontrolled blackouts across the state.

The quick decision that grid operators made in the early hours of Monday morning to begin what was intended to be rolling blackouts — but lasted days for millions of Texans — occurred because operators were seeing warning signs that massive amounts of energy supply was dropping off the grid.
