So having the user involved and being able to tailor to his needs is really important. But it's really challenging because that's one of the big unpredictable, unpredictable things. You need to deal with that volatility in that behavior or that stochasticity in that behavior. Specifically, if you want to exploit flexibility services where, for example, you need to upfront allocate certain capacity.
