That wind power generating capacity is intermittent capacity and cannot be relied upon is obvious but sometimes escapes notice in the enthusiasm for “renewable energy”. That wind power must be backed up by other more reliable generating capacity for the periods when winds are too low or too high or when the weather is too cold is also often glossed over. That wind power must be used when the wind does blow irrespective of level of demand and thereby displace more stable power (thus rendering it more expensive) is an inevitable consequence.
The following report comes as no surprise.
METEOROLOGICAL MUSINGS reports:
from the “Dallas Morning News”The Electric Reliability Council of Texas said 7,000 megawatts of generating capacity tripped [“tripped” means failed]Tuesday night, leaving the state without enough juice. That’s enough capacity to power about 1.4 million homes. By rotating outages, ERCOT said it prevented total blackouts.“We have the double whammy of extremely high demand, given the lowest temperatures in 15 years, combined with generation that’s been compromised and is producing less than expected or needed,” said Oncor spokeswoman Catherine Cuellar. Oncor operates power lines in North Texas and facilitated the blackouts for ERCOT.The article didn’t give a clue as to what generating capability failed, but I can make a pretty good guess: Wind energy…For a time, Texas was bragging about being the #1 state for “wind power” (it still is) and we were bombarded with TV commercials and newspaper editorial touting the “Pickens Plan” for massive spending on wind energy. Pickens himself was building a huge wind farm in northwest Texas. He has now ceased construction.Now, because of relying so much on wind power, the state is suffering blackouts.Mexico is trying to help by shipping power to Texas, but it is not enough.
