Comment A battery is not a generator (Score 1) 80
Batteries are measured in Watt-Hours, NOT Watts. They store energy, they don't generate it. Thus the statement "California has added 18.5 gigawatts of new resources. Of that, 6.6 gigawatts were batteries..." is nonsensical. A gigawatt of coal or natural gas generation is a gigawatt as long as fuel is available, a gigawatt of wind lasts as long as the wind blows hard, and a gigawatt of solar lasts as long as the sun shines strongly. The difference between battery storage and true generation is that the battery is only time-shifting previously generated energy, not actually generating any new energy. Thus the 6.6 gigawatts of battery can't be meaningfully part of the 18.5 gigawatts of new resources. The battery plant is chemically limited to its specified capacity, regardless of how much coal-, natural gas-, solar-, or wind-derived energy is available to store. It's more likely that the battery number is gigawatt-hours, which means the "generation" capacity of the battery is one hour at that load.
California's quoted numbers are highly misleading, if not outright lies.
