Analysis should include

identifying pressure needs to meet demand
identifying market constraints specific to the system
calculating end-user total connected load
calculating pressure drop over a specified distance in the system
explaining storage mechanisms for meeting peak demand
understanding the use of telemetry and supervisory control and data acquisition (SCADA) in monitoring and controlling the gas system.

Process/Skill Questions:

When is it necessary to heat the gas?
What is telemetry?
What percentage of natural gas supply is used for electricity production? What are the seasonal differences?
What are the advantages and disadvantages of using natural gas vs. other energy sources for electricity production?
