We can study the number of hours in which the expected margin falls below the threshold margin after imports from other subregions just as we did before imports. The same charts from the LOLH section are shown here, but this time we compare the number of hours of risk before imports with the number of hours of risk after imports. By selecting CAMX, for example, you will see the 54 hours of risk that we saw in 2020 have been reduced to two. The remaining two hours of risk should then be studied with the subregion to determine whether there is a way to mitigate the risk.
All areas can alleviate risk in the system through transfers, except a few hours in the CAMX area beginning in 2020, and growing over the next 10 years.
Clicking a region on the map will change the charts to show that area's information. Clicking the same area again will switch the charts back to the overall Western Interconnection results.
