When Cook inlet is the sole/source monopolistic supplier, and Enstar is the monopolistic buyer collaborating  with them you will get monopolistic practices - the analysis, investigation and consumer-protecting regulation of which is one key reason the Regulatory Commission  exists!

With climate change we have only had one cold winter in the past half/dozen. Over the same time-frame we also vastly increased ng supplies thanks to expanded Cook Inlet activity. 
The Commission should justify its approval based on use, cost and data trends over more than a one-year blip! This is a huge increase!
