Natural gas purchasing is generally deregulated on a federal or interstate basis. However, intrastate, there are many conditions that come into play which typically translate into higher costs for the commercial or industrial user. This book is intended to serve as comprehensive reference which can be used by the natural gas purchaser to sort out both the potential pitfalls that can negatively impact gas costs, and the opportunities for significant savings available to the informed user. Each step in the process of natural gas production and delivery to the marketplace is thoroughly examined, including production, inter/intrastate transportation, regulation, cost factors, local distribution, company structures, and deregulation processes. Also fully covered is the natural gas LDC billing process, and how understanding it can lead to significant savings.
