Wind power output in Texas is trending down even as wind generation capacity increases

By Ed Ireland -- February 16, 2024
The inherent unreliability of wind power is highlighted by the recent experience in Texas.

I have written extensively about the intermittent nature of wind power (here, here, and here), highlighting that the only way wind power has survived and continues to increase is through federal tax subsidies. Wind proponents have long argued that the intermittent nature of wind is offset by over-building wind generation, based on the theory that the wind is always blowing somewhere.

The reality that the wind is not always blowing where it is needed, even over very large areas, is highlighted by the fact that wind power in Texas has been declining.

Total wind power generation in January 2024 was less than in January 2023. According to Reuters in an article published on February 16, 2024:

Cumulative wind power output in 2023 was 4,500,000 MWh, compared to 4,400,000 MWh in 2022, LSEG data shows.

Electric Grid Reliability: Texas vs. EPA

By Ed Ireland -- October 10, 2023

“Just the possibility that EPA will enact such sweeping regulations will slow investment in new power generation that all U.S. power grids need. Recent grid warnings about possible outages this summer will likely continue into the winter while potential new-generation projects proceed cautiously.”

The U.S. Environmental Protection Agency (EPA) recently proposed new greenhouse gas standards for fossil-fuel-fired power plants. These draconian regulations, part of the Biden Administration’s “all of government” climate policy—which is at odds with affordable, reliable energy—threaten the stability of the U.S. power grid.

The EPA plan is the “nuclear option” of regulations because the agency is not just proposing new regulations designed to meet more stringent clean air standards with fines if the criteria are not met. Instead, EPA seeks to impose unachievable CO2 emissions targets that will shut down existing coal and natural gas power plants and threaten the viability of the nation’s power grids.…

ERCOT Readies ‘Retired’ Gas Generation for the 2023/24 Winter Peak

By Ed Ireland -- October 4, 2023

“Much of the generation named by ERCOT as qualified under their latest RFP is generation units that were recently retired, many because they could not compete with the artificially low prices that heavily subsidized wind and solar can offer, so they are still operational.”

The Electric Reliability Council of Texas (ERCOT), the planning agency for 90% of the state’s grid, has a wind/solar tiger by the tail. As the agency does not exchange power with its out-of-state neighbors to avoid federal (FERC) jurisdiction, it is looking at home for able, firm generation that wind and solar unfairly (via government intervention) put out of operation.


ERCOT is (in)famous because its grid almost collapsed during Winter Storm Uri in February 2021. The Texas electricity grid had lost so many generators due to the storm that it was only 4 minutes and 37 seconds from collapsing, which would have required a restart from a “black start.”…
