Encouraging. However, it isn't clear from the article at first glance (or the deeper analysis being referenced) how electricity consumption by power source is changing.

In other words, as an example, a 10% increase in solar power generation does not necessarily mean that there was a 10% increase in electricity consumption where that electricity was generated via solar.

i.e. It is entirely possible for a growing solar fleet to generate more power during the middle of the day than previously, and simultaneously for not all of that increased power to be used / usable.
