Ever See Electric Grid Power prices go Down? (costs, increase, price)

[Philip T]

Floating this idea around for some perspective --

Sort of less practical topic than most . . .

But have any of you ever seen Electric Grid Power prices go Down?

Everyone is used to the retail price going up . . . Natural Gas goes up -- so the Electric kW/h rate goes up. Coal price goes up -- so the kW/h price goes up. On and on.

BUT . . . whenever the NG or Coal or whatever other increased costs are stated to be the cause of the increase goes DOWN . . . does anyone ever see the kW/h price go down?

I am not really talking about time-of-use discounts (typically deep night is cheaper for large institutional scale users), or industrial negotiated pricing . . . but just normal, go-to-work Joe and Jane Consumer prices.

Is this all just a one-way (up) Ratchet Wrench, or has anyone seen them come down, as well?

Thanks.
