Electric System Reliability:
My presentation to the Engineering and Science Council of Houston Oct 7 2023.
The same presentation recorded in my home office prior to Oct 7.
The presentation slides. Why not 100% renewables? The Excel file is shown below as file ERCOT22A.xlsx.
ERCOT22A.xlsx is the current ERCOT system using 2022 hourly data with CO2 sources producing 59% of the energy (7.3 c/kWh).
ERCOT22C.xlsx 30 GW nuclear long 200 hr thermal storage using 2021 Storm Uri has no CO2 from gas peaking and works with renewables (10.2 c/kWh).
ERCOT22C1.xlsx 30.5 GW nuclear long 200 hr thermal storage using 2022 Storm Elliott has no CO2 from gas peaking and works with renewables (11.7 c/kWh).
Dr Forsberg American Nuclear Society 2023 Nuclear thermal CRUSH storage presentation.
