RE:AEP to sell Kentucky operations to Liberty
The way I read this, the incumbent has the same long term objective as AQN i.e reduce carbon emissions and increase green generation. So the incumbent with full detailed knowledge of the operations thinks it's better to sell the operation rather than improve it. I assume that if AEP was to implement the changes they would be more or less similar to what AQN is planning to do.
Perhaps there is a tax advantage for AEP to sell rather than modernize but failing that I would guess the advantage is with the seller.
