Paying for the plant but not having to pay for it to run most of the time is probably cheaper than having it running most of the time.

Maybe there's opportunities for net metering for customers with backup generators. At the right price per kWH, I would run my generator and feed into the grid... personally, my fuel cost is likely too high for that to make sense very often, but I think there's likely some hidden capacity there with the right incentives.
