I think you missed the part about studies that make the case that utilities could be doing this today. Utilities are conservative though, I don't expect them to jump in with both feet right away.
> This is, of course, speculative. We don’t know if the study findings scale to the whole of the United States. It’s back of the envelope math. Atop that, the study itself is an analysis, which is not the same value as experience.
Hence my question. Do we actually see any utilities making steps in this direction?
They're openly talking about it. Let's look again in ten years, given the lead time, conservatism, and regulatory concerns at this scale. "Fail fast" isn't really an option for the grid the way it is for software startups.
I realize I may have come across somewhat pugnaciously above. I am honestly curious about this, though.
What utilities/where are talking about this right now? What level of talk are we talking about? Public statements? Designs? Construction permits in the works?
My research has shown that while many utilities have purchased storage (SCE 250 mW in 2014[1]) it's still very experimental and they do it mostly for research purposes or publicity or because the regulator makes them. However, since the electricity business is slow moving, low margin and very capital intensive it's clear why everyone is very interested in any new potentially disruptive technology. Imagine owning a peaker power plant that you've paid for in full using debt and generates a little profit each year under the condition that it can be amortized for 15 more years - if someone built the equivalent of a peaker plant made of batteries, even in 2025, you'd still go under. Scary.
In many states, utilities do not generate power they merely buy it. They call it energy deregulation.
If it really were possible, you'd see companies like Exelon attaching battery storage to their nuke and coal plants to feed it back at a profit during peak rate periods.
My guess is that isn't cheaper than using peaker plants yet.
Hence my question. Do we actually see any utilities making steps in this direction?
