AS OUR POWER GRIDS TRANSITION
toward a decarbonized energy mix, ensuring
reliability and provision of grid services remains
paramount. The power system has always been
heavily influenced by the weather-extreme
temperatures determine the timing of peak
demand, winter cold snaps can limit natural
gas supply, gas turbine reliability and output
are affected by ambient conditions, and
hydro output varies seasonally and annually.
However, as the grid increasingly relies on
variable renewable energy (VRE), like wind and solar,
the attention to reliability and weather conditions is
increasingly important. The implications of changing
reliability are large. The Electric Reliability Council of
Texas (ERCOT) rolling blackouts from earlier this year
impacted millions of people across the state and could
be seen from space (Figure 1).
One dimension of grid reliability is resource adequacy
(RA) analysis. It is used to determine if there
are enough resources available to meet load while
accounting for uncertainty in generation availability,
