California Has So Much Solar Power That Other States Are Paid To Take It (mic.com)

"On 14 days during March, Arizona utilities got a gift from California: free solar power," reported the Los Angeles Times. Mic reports: California is generating so much solar energy that it is resorting to paying other states to take the excess electricity in order to prevent overloading power lines. According to the Los Angeles Times, Arizona residents have already saved millions in 2017 thanks to California's contribution. The state, which produced little to no solar energy just 15 years ago, has made strides -- it single-handedly has nearly half of the country's solar electricity generating capacity...

When there's too much solar energy, there is a risk of the electricity grid overloading. This can result in blackouts. In times like this, California offers other states a financial incentive to take their power. But it's not as environmentally friendly as one would think. Take Arizona, for example. The state opts to put a pin in its own solar energy sources instead of fossil fuel power, which means greenhouse gas emissions aren't getting any better due to California's overproduction.

The Los Angeles Times suggests over-construction of natural gas plants created part of the problem -- Californians now pay roughly 50% more than the rest of the country for power -- but they report that power supplies could become more predictable when battery storage technologies improve.

    The journalist is (a) clueless about energy production and (b) a careless writer.

    Just one example of the latter: "free" is not "paying other states to take it". Which is it? I'm not going to bother to look, but what crappy writing and editing.

    Meanwhile: What happens when the sun doesn't shine? A big cloud rolls across that 2 square mile patch of solar cells? Something has to kick in, and fast. That something are the natural gas plants that the journalist is criticizing. The more solar power you install, the more fast-reaction generating capacity you need. So you pretty much build a watt of natural-gas generation for every watt of solar you install.

    Of course, a nice, green alternative would be a pile of hydroelectric storage plants up in the mountains: Two lakes, one up and one down. When there's too much power, you pump the lower lake into the upper. When you need fast power, you drain the upper lake through turbines into the lower. It works really well, but I'm sure the eco-types would have a total fit at all the flooded valleys. So they get natural gas plants.
