WSJ Pushes Back Against the Left's 'Renewables' Lobby Amid Texas Energy Catastrophe

Following-up from yesterday, "Global Warming is Man-Made," the Wall Street Journal comes back with a humdinger of an editorial.

See, "Texas Spins Into the Wind: An electricity grid that relies on renewables also needs nuclear or coal power":

While millions of Texans remain without power for a third day, the wind industry and its advocates are spinning a fable that gas, coal and nuclear plants—not their frozen turbines—are to blame. PolitiFact proclaims “Natural gas, not wind turbines, main driver of Texas power shortage.” Climate-change conformity is hard for the media to resist, but we don’t mind. So here are the facts to cut through the spin.

Texas energy regulators were already warning of rolling blackouts late last week as temperatures in western Texas plunged into the 20s, causing wind turbines to freeze. Natural gas and coal-fired plants ramped up to cover the wind power shortfall as demand for electricity increased with falling temperatures.

Some readers have questioned our reporting Wednesday ("The Political Making of a Texas Power Outage") that wind’s share of electricity generation in Texas plunged to 8% from 42%. How can that be, they wonder, when the Electric Reliability Council of Texas (Ercot) has reported that it counts on wind to meet only 10% of its winter capacity.

Ercot’s disclosure is slippery. Start with the term “capacity,” which means potential maximum output. This is different than actual power generation. Texas has a total winter capacity of about 83,000 megawatts (MW) including all power sources. Total power demand and generation, however, at their peak are usually only around 57,000 MW. Regulators build slack into the system.

Texas has about 30,000 MW of wind capacity, but winds aren’t constant or predictable. Winds this past month have generated between about 600 and 22,500 MW. Regulators don’t count on wind to provide much more than 10% or so of the grid’s total capacity since they can’t command turbines to increase power like they can coal and gas plants.

Wind turbines at times this month have generated more than half of the Texas power generation, though this is only about a quarter of the system’s power capacity. Last week wind generation plunged as demand surged. Fossil-fuel generation increased and covered the supply gap. Thus between the mornings of Feb. 7 and Feb. 11, wind as a share of the state’s electricity fell to 8% from 42%, according to the Energy Information Administration (EIA).

Gas-fired plants produced 43,800 MW of power Sunday night and coal plants chipped in 10,800 MW—about two to three times what they usually generate at their peak on any given winter day—after wind power had largely vanished. In other words, gas and coal plants held up in the frosty conditions far better than wind turbines did.

It wasn’t until temperatures plunged into the single digits early Monday morning that some conventional power plants including nuclear started to have problems, which was the same time that demand surged for heating. Gas plants also ran low on fuel as pipelines froze and more was diverted for heating.

“It appears that a lot of the generation that has gone offline today has been primarily due to issues on the natural gas system,” Electric Reliability Council of Texas senior director Dan Woodfin said Tuesday. The wind industry and its friends are citing this statement as exoneration. But note he used the word “today.” Most wind power had already dropped offline last week.

Gas generation fell by about one-third between late Sunday night and Tuesday, but even then was running two to three times higher than usual before the Arctic blast. Gas power nearly made up for the shortfall in wind, though it wasn’t enough to cover surging demand...

Still more.
