Here is what I do not understand about these kinds of dynamics: Are they not the perfect way to encourage the creation of energy storage companies and technologies?
It seems like there is a massive opportunity to purchase energy when it is cheap or even negatively priced, figure out some way of storing it, and then sell it back once the price is higher. Over time, this could stabilize the grid and encourage development and scale benefits in energy storage.
Where are these companies? Are the technologies not yet efficient enough, even when the price of electricity is negative? Or is this technology being deployed already?
EDIT: Well turns out this is covered in the article. Hoping there will be more development in this direction in the future!
Because storage is hard and expensive.
Generating energy is easy (with renewables).
6% is not really a lot. I guess batteries can be profitable if you cycle daily. But at 6% curtailment, they would've been used only a few times a year. You'd need really cheap storage for that.
> figure out some way of storing it
My hypothesis is this being the issue.
