Much misinformation out there about #Texaspoweroutage, @ERCOT_ISO, wind and solar power, and thermal generators (gas and coal). Let's review what we think we know right now. @TPPF @Life_Powered_ 1/10
Two problems in #Texas, one short term and exacerbated by the long term issue, and one long term. 2/10
The short term failure came at about 1 AM Monday when #ERCOT should have seen the loads soaring due to plummeting temperatures and arranged for more generation. 3/10
Texas came very close to having a system-wide outage for the whole state (ERCOT area, about 85% of the state) due to not arranging for more generation. 4/10
This tripped the grid, knocking some reliable thermal plants (gas and coal) offline. This was a failure of the grid operator (ERCOT) not the power plants. 5/10
In the last 4-5 years, Texas lost a net of 3,000 megawatts of thermal out of a total installed capacity 73,000 megawatts today. We lost the thermal power because operators couldn’t see a return on investment due to be undercut by wind and solar... 6/10
...which is cheap for two reasons – it’s subsidized and it doesn’t have to pay for the costs of grid reliability by purchasing battery farms or contracting with gas peaker plants to produce power when needed, not when they can. 7/10
Meanwhile, Texas has seen a growth of 20,000 megawatts of wind and solar over the same period to 34,000 megawatts of installed capacity (they rarely perform anywhere close to capacity). This subsidized (state and federal) wind and solar have pushed... 8/10
...reliable thermal operators out of business or prevented new generation from being built as operators can’t make money off of the market. This reduced the capacity margin – grids must have excess capacity to ensure stability. 9/10
Texas is experiencing what California has – with California affecting the entire Western Interconnection due to its policies. Blackouts are a feature of the push to have more unreliable renewables on the grid. Must pay $$ for reliable backup w/ renewables 10/10

More reports about the Feb. defection of China's vice minister of State Security, Dong Jingwei (董经纬), the highest ranking defection of a People's Republic of China official ever. He ran counter intelligence ops (spy-catcher) & has #Wuhan lab leak info. 1/4
#Dong's defection is likely the biggest story of the year regarding #China and the #COVID19 virus - unless the the aftermath of his defection causes #China to use military force. Dong would be in position to know about the Wuhan Institute of Virology. 2/4
It may be that the timing of the defection was why we suddenly saw the engineered #COVID virus theory gain purchase among corporate media outlets. A Chinese defector confirming this would lead to calls for China to pay reparations for the deaths they caused. 3/4

How government mandated training often works in the real world (applicable to sexual harassment training, mandatory critical race sessions, etc.). In March of 2007, as a California State Assemblyman, I had to report to a required class on sexual harassment. 1/n
The class was required by AB 1825, passed in 2004. The law required employers with 50 or more employees to provide 2 hours of training and education to all supervisory employees every two years.… 2/n
Eventually, about 30 elected members of the State Assembly showed up for the class. I say eventually, because several of the Democrats, including members who voted for the bill, showed up 24 minutes late. 3/n

I see there's some discussion over people moving to #Texas. That's great. About 40% of Texans weren't born in Texas. @DaveTurbohawk @Cleansniper23 1/6
Generally, states with more freedom attract more migrants, domestic and international, than states with less freedom. People vote with their feet. There are 3 polls over the years that suggest that the people moving to #Texas are not a political threat. 2/6
In the most recent year reported, about 560,000 people moved to Texas from the U.S. and about 450,000 people moved out. (See:…) @TPPF 3/6

I've been reading the #Texas House Committee Substitute for SB10…, a bill which, as filed, sought to ban counties and cities from using taxpayer funds to lobby the legislature. @TPPF 1/n
Last Friday, the House State Affairs Committee amended the bill beyond all recognition. Now, instead of a ban on lobbying by cities and counties, lawyers are allowed unlimited lobbying and they no longer have to report it. 2/n
Further, SB10 now repeals SB65 authored by @TeamBettencourt in 2019 and signed into law by @GovAbbott. SB65 required Texas's political subdivisions to report their lobbying expenditures. Many have dragged their feet and not reported.… 3/n

See the second page of @ERCOT_ISO's latest reliability assessment.… Under the top table describing the reserve margins, they have a table labelled “Range of Potential Risks.” 1/10 @TPPF @Life_Powered_ #texaspoweroutage
Something between the 4th and 5th columns is what happened this week. Add 2,000 MW of demand above ERCOT’s adjustment here (they assumed a record of 67,200 MW) and 10,000 MW from planned thermal outages, likely for maintenance, going into the cold front. 2/10
Take out another 1,600-1,900 MW from lower wind production than in the baseline, and reserves are below 2,000 MW. That’s where Texas was Sunday night. 3/10

Thoughts on the state of the race for President. Running for a major office is an exhausting endeavor. In my own experience, I had two intense campaigns: my first primary win for California State Assembly in 2004 and my run for the U.S. Senate in 2010. 1/9
In 2004, I was up against 5 other opponents, including a self-funded candidate who had about $1 million spent on her behalf. Each day was a contest: raising money, giving speeches, seeking endorsements, meeting voters.… 2/9
I flew up to Sacramento to seek support from lawmakers and various trade associations. At the end of the day, I flew back to Orange County. I was in the airport, having dinner, when I saw my main opponent. I was exhausted. 3/9
