The hypothesis makes sense — a dispatchable technology would be dispatched more closely to the demand curve, and as such, variations in the resultant wholesale price for each interval would be smaller. Bbbbutttt in my experience, assumptions are flawed, and you need to really see it in practice. Remember, this is a system driven primarily by fluctuations in human behaviour — our consumption of electricity — and so it’s very, very hard to predict the trajectory of changes accurately.

But yes, absolutely, we’re underestimating the urgency of large-scale solar power, and large-scale storage. While I always try and champion the successes we’ve had to date, we’re not without a clear set of challenges in the future. Articles like the one I mention above make those challenges much harder.
