Any recommendation for introduction data science applied to energy storage, grid pricing etc?

My wife has a background in applied mathematics and she is now working on financing renewable energy projects.

Batteries and energy storage in general are an important part of that industry and she is interested in learning how to code. Ideally in the context of data science and energy storage, energy pricing etc.

Anything related to these two fields could be of interest to her, so any links are welcomed!

Thanks.
