Texas to Add 35 Gigawatts of Wind & Solar in Next 3 Years — Boosting Grid Resilience
By Zachary Shahan

Clearly, the news story of the week — nicely past CleanTechnica — has been Texas and a few neighboring areas freezing over and dropping electrical energy. The overwhelming majority of the ability vegetation that went offline have been thermal energy vegetation (largely pure fuel). They weren’t geared up sufficient for the chilly. Numerous wind generators have been additionally down as a result of nobody had purchased the “cold-weather package.”
To the extent Texas is including wind & photo voltaic to the grid, these plans have been made lengthy earlier than Winter Storm Younger Dryas. The notion that that is for the aim of “boosting grid resilience,” is completely fracking retarded.
Solar is flat-out not a consider Texas’ electrical grid. While wind is a key part of our grid, producing 20-24% of our electrical energy over latest years. It completely failed over the previous 10 days. As temperatures dropped under regular within the DFW space on February 7, wind output dropped from 35-65% of capability to 10-30% from February 9-18. Over the identical time interval coal and pure fuel energy vegetation ramped up to practically full capability in a short time. As of Sunday February 14, the system was functioning usually. As temperatures plunged from 20 to 40 °F under regular within the DFW space, some thermal energy vegetation went offline for a wide range of climate and demand surge associated points and by Monday morning ERCOT was in full emergency mode.
The graph above is preliminary, a “work in progress.” I’m nonetheless engaged on gathering more detailed information on capability by gas sort. However, it clearly demonstrates that more wind era capability would have been as ineffective as mammary glands on a bull.
ERCOT’s single largest failure was the shortage of dependable backup capability for wind energy… ERCOT anticipated the wind energy to fail below these circumstances. It seems to me that the one approach ERCOT may have made it by means of this unscathed, would have been for pure fuel, coal and nuclear energy to have delivered 80-90% of capability for 7-10 days throughout record-cold climate (20-40 °F under regular within the DFW space) with a system geared towards hotter than regular climate. This was not a sensible expectation. ERCOT additionally failed to be sufficiently proactive in implementing rotating outages and after they did, they have been unable to adequately rotate the outages.

Why wind generators in New York hold working in bitter chilly climate in contrast to those in Texas
Updated Feb 19, 2021
Syracuse, N.Y. — Texas Republicans have been fast to blame the state’s wind generators for the large energy outages that tens of millions of Texans skilled this week throughout an uncommon blast of chilly climate.
Texas leads the nation in wind energy, with practically 15,000 wind generators producing 23% of the Lone Star State’s electrical energy final 12 months. Many of the generators shut down when the chilly descended on Texas.
But we couldn’t assist however marvel why wind generators in cold-weather states like New York can function within the winter with seemingly little bother when their counterparts in Texas can’t.
“There are a variety of cold weather and anti-icing technologies that are used on wind turbines in the coldest regions,” she mentioned. “These technologies help prevent the buildup of ice on turbine blades, detect ice when it cannot be prevented, and remove ice safely when it is detected.”
The sensors may even inform which blades have ice on them and which of them don’t. When ice is detected, heating components contained in the blades activate to soften the ice.
For security causes, the generators are shut down whereas the heating components soften off the ice, Kurt mentioned. That approach, there’s no probability of ice flying off spinning blades, doubtlessly damaging the generators or, worse, hanging somebody on the bottom, she mentioned.
“We’d rather the ice drop below the turbine,” she mentioned.
Once the ice is eliminated, the generators are turned again on and the blades can safely spin within the wind once more.
In Texas, wind generators usually are not geared up with such de-icing packages as a result of operators there by no means anticipated to want them, Kurt mentioned.
“Turbines in Texas are built for the type of temperatures they usually get in Texas, where it’s 110 degrees, not 10 degrees,” she mentioned. “It’s a cost thing.”

So… Heating components (which require electrical energy) soften the ice and the wind generators have to be shut down to deice them? Maybe that’s why New York’s wind generators generate nearly no electrical energy all winter lengthy.
Unlike New York, Texas doesn’t have a pleasant, regular, winter electrical energy load. Our load varies fairly broadly and our wind generators can generate over 40% of our electrical energy on favorable days. Even on the peak of our latest deep freeze, Texas wind generators generated more electrical energy than New York’s. There are days when Texas wind generators generate more electrical energy after which all of NYISO.
Texas wants to winterize no less than some portion of its most dependable era capability: pure fuel, coal and/or nuclear. Texas doesn’t want to emulate what doesn’t work in New York.
