Actually, NERC found that MISO provided mismatched data and found, in stead of MISO being at high risk in the near term, that MISO was at elevated risk in the 2028-2031 timeframe – with resource adequacy being vulnerable to extreme weather events. In either case, SMRs wouldn’t be ready to fill the shortfall. Moreover, the SMRs likely to be available first (if at all), will use voluminous amounts of water to generate steam to run turbines that, in turn, generate electricity. As such, they would be vulnerable to drought and extreme heat.
MISO wrote:
“Following an in-depth review, NERC found that MISO submitted mismatched data, which overstated the near-term energy shortfall risk. When reanalyzed with the corrected data, the MISO footprint was reclassified as an “elevated risk” over the next few years, shifting to “high risk” in the 2028–2031 timeframe, depending on new resource additions/retirements. Elevated risk areas meet resource adequacy criteria; however, under extreme weather conditions these areas are likely to experience a shortfall in reserves.”
