2026 Demand on CAISO grid down 1.84% v '25; 1.22% v '24; and 2.27% v '23
Due to growth in behind-the-meter roof PV, which eliminates need for grid electricity
Also, CA has 2.5 million EVs vs only 400,000 in TX so more electricity demand there.

"South Australia is proving to the world that relying largely on wind+solar energy with battery back-up is incredibly cheap, with electricity prices tumbling by 30% in a year..."

"CA's mandatory building and appliance efficiency standards... Electricity demand is growing much more slowly in California than in Texas where almost no energy-efficiency standards have been imposed."
www.researchgate.net/publication/...
Why? Stronger effic & building standards & more BTM PV in CA
Far fewer homes in TX have these features, so TX wastes far more
In the industrial sector, the ratio is 5.18x
Why? Stronger effic & building standards & more BTM PV in CA
So, when someone points to CA's high electricity price, explain that what people pay is price x use, and electricity use/person in CA is the lowest in the US
Why? Stronger effic & building standards & more BTM PV in CA
The days are over where gas, coal, or nuclear is needed to keep a small city operating with zero solar or wind
Calistoga, California can operate for 48 hours during a blackout with a 8.5 MW/293 MWh battery-H2-fuel cell system

Louisiana bets big on ‘blue ammonia

2025 avg capacity factor of all 21.58 GW* of solar on the @California_ISO grid:
30.2%
2024 CF US coal:
42.6%
www.eia.gov/electricity/...
->Coal not much more reliable than CA solar
*=avg Dec '24 & Dec '25 nameplates
Solar output: 57,054 GWh/y
but CA also has 15.8GW/63.2GWh of batteries, which can store 63.2GWh/d of PV and then discharge 3.95GW of flat output for 16h
So PV+batteries can provide ~2x the baseload output of nuclear in CA (2.2GW) for 24 h in a day
