As those plants age out of their usable lifetime, Kentucky utilities will have to choose between some combination of renewables and storage or natural gas or nuclear, all of which have higher costs than operating the defunct coal plants, but lower capital costs than building new coal plants. This will result in a rise in their prices over time.
Of course, comparing the future costs of new non-coal plants doesn't account for the huge existing public health and environmental costs of burning coal for electricity, which would be avoided by any of the other technologies.
I’m hoping Kentucky starts to do more solar as it is pretty decent for sun, but the local politics likely think solar + stationary battery storage is some lib-ruhl conspiracy.
