Blackouts are likely to continue in ERCOT because of these shortcomings:
Load management (load shedding) is being greatly expanded because of insufficient supply.
ERCOT was not given sufficient rules and accountability measures to insure reliability.
The more curtailments there are the more gas supply backup systems will be installed.
Electric curtailments with customer gas backups might bring down the gas supply also.
Gas delivery systems are not designed to serve all gas customers for extended times.

Historical RTS Development (newest to oldest):
RTS3 program (.exe) has storage and uses the modernized 2020 RTS data files.
2020 RTS3 NREL Update at PMAPS 2018 and similarly for the Austin Physics Group.
NREL new RTS model entry point and reliability indices models.
The 1979 RTS generation distibution is a poor fit to a Normal distribution curve.
For overlapping f(x) distributions this shows what not to shade as the overlap.
1979 RTS excel spreadsheet shows how to find LOLH and EUE from load and generation F(x).
An example for how to correctly calculate LOLH and EUE from f(x) or F(x) distributions.
Older RTS3 which includes a Matlab version. See the LOLE seek feature in operation. expands RTS1 to a two area model bringing transmission constraints into LOLP studies. has all the 1986 and 2016 files plus multi-state generators and auto LOLE capability.
RTS2016 info describes an LOLE program for evaluating the capacity value of wind, water, and solar. has four UK case studes and all associated files including the program code and executables. runs example cases verifying the new RTS program reproduces 1986 IEEE RTS paper 'exact' indices.
