The issue in the article wasn't an actual shortage of gas, the gas was there it just couldn't be accessed because of the power outage. The pumps and payment processing equipment isn't that power hungry and could be powered by a small generator.

I'm not sure I see much distinction between (a) a shortage of usable gas because nobody is bringing in gas, versus (b) a shortage of usable gas because nobody is bringing in generators to run the pumps. In both cases people could get access to a lot more gasoline if there was enough money to be made by, say, loading up a pickup truck and driving quickly to the affected area.

... But it sounds like you're not arguing for price controls, specifically, but for some kind of government intervention. I agree that requiring backup generators sounds like a much better policy than anti-price-gouging laws, since it's at least not obviously counterproductive.
