TIDBIT: FROZEN TEXAS TURBINES
Apropos of today's main blog, there's now a conflict emerging in the frozen Texas turbines story:
Note this paragraph from the second article and its implications:
While some early reports indicated that frozen wind turbines were causing significant shortfalls, 30GW is roughly equal to the entire state's wind capacity if every turbine is producing all the power it's rated for. Since wind in Texas generally tends to produce less during winter, there's no way that the grid operators would have planned for getting 30GW from wind generation; in fact, a chart at ERCOT indicates that wind is producing significantly more than forecast.
So while having Texas' full wind-generating capacity online would help, the problems with meeting demand appear to lie elsewhere. An ERCOT director told Bloomberg that problems were widespread across generating sources, including coal, natural gas, and even nuclear plants. In the past, severe cold has caused US supplies of natural gas to be constrained, as use in residential heating competes with its use in generating electricity. But that doesn't explain the shortfalls in coal and nuclear, and the ERCOT executive wasn't willing to speculate.
