1. NATURAL GAS ECONOMICS AND BUSINESS ISSUES

2. ©UH IELE, 2 No reproduction, distribution or attribution without permission. What is the natural gas business… …and how should it be regulated? Is it a competitive, upstream-driven business? Is it an economies of scale, monopoly midstream-downstream business that affects the public interest? How much of direct end use and conversion is competitive? If the goal is to build the “natural gas factory,” then policy/regulatory approaches need to facilitate value chain development – “commercial frameworks.” Where does most profit, value creation take place?
