I could be misreading, but looking at the first graph, 2024-2025 had a fairly big jump in average GWh from solar. But 2025-2026 has a not very big jump? Very easy to misread, though.

Same with the very bottom set of three plots. Between 2025-2026, there's not much change in solar that I can see, but there's a huge change in night-time and morning imports, which depresses natural gas a ton.

Nighttime generation from SunZia would be a likely cause; at least in California night time wind is stronger than day time, usually, I wonder if New Mexico is the same.

Hybrid solar-battery setups that feed batteries directly when the price drops could be part of the answer.

I'd guess if the numbers for grid energy fed to batteries and the output from were compared it might be possible to discern if there was a source of energy that didn't go via the grid and so didn't show up on the stats.

The 2026 solar graph doesn't include summer. California produced solar power at about the same rate in January through May this year as it did January through December last year.

Summer is excluded from all years in the bottom and top graphs, the ones I was referring to.
