Consumers were insulated from this because they only pay the price in their contract, not the wholesale price. There was one provider that offered lower rates in exchange for not giving that protection, which did not work out very well.
And people in the US commonly shell out hundreds of dollars per month for electricity. I've never even approached anything close to a hundred.
Is this due to fluctuating pricing or high usage? It seems that Texas bills vary between a monthly average of $100-200. That seems a lot to me, but the average unit price is pretty good.
