Accessing @TestVisible variables seems useful, but I think it might limit the flexibility of the test data.

I feel like querying existing records could lead to issues with test isolation, but I can't recall the specifics.

Okay, I've got a strategy for this. I'll first eliminate any options that don't seem relevant, then focus on the remaining choices and try to determine the most likely answer based on my understanding of charge plans.

I remember something about pricing related to demand during peak times, but I'm struggling to remember the exact term. Incremental rates? Maybe?
