There is no mention of "cord cutting" in TFA. The power company will just route "cleaner energy" to MS through the existing network.
You're being pedantic.
"Cutting the cord" is a phrase that means they will not be buying energy from the utility, which comes from a number of sources including coal and other "unsustainable" and dirty sources. Instead they will contract and buy from "green" sources that will then me routed into the pool of power that the utility then delivers to MS.
Seriously, think it through.
