ERCOT long range non CO2 resource plans do not exist.

Note that ERCOT does not do generation planning. That is left to the market.
ERCOT envisions wind, natural gas, peak shaving solar, and growth reductions.
This plan is dependent on abundant natural gas and no CO2 regs for using gas.

Flow batteries are the most likely technology to replace natural gas backups.
Solar will find a permanent home for peak load shaving but not for base load.
To serve base load with wind will require an inordinate amount of wind power.
By 2100 nearly all the west and coastal areas would be covered by wind farms.
The energy storage requirements would be enormous because wind is so erratic.

The public knows little about the IFR but it holds great promise for our kids.
I would recommend a future wind, solar, flow batteries, and IFR nuclear plan.
A robust plan is 20 GW solar, 20 GW wind, 20 GW batteries, and 20 GW nuclear.
Once we have this or another base case working we can build alternatve cases.
Note that noone has actually shown that a future non fossil plan is workable.
A valid design will have a loss of load meeting 0.1 hours/yr LOLH reliabilty.

I need to work on an affordable and electrically valid long range non CO2
plan that meets a 0.1 Loss Of Load Hours per year reliability requirement.
