1 Study Results High Gas Sensitivity Low Gas Sensitivity High High Gas Sensitivity Low Low Gas Sensitivity This slide deck contains results from the 2011 TEPPC Study Program. This study shows the results of how production cost, generation dispactch, and transmission utilization differ from the Common Case and a result of different gas prices.

2 PC1-3 – High Gas Price Sensitivity Central Question: How does production cost, generation dispatch, and transmission utilization change if gas prices are greater than assumed in the Common Case (CC)? Change to starting input assumptions: –Loads – none –Transmission System – None –Generation – Henry Hub gas price increased from $5.43 to $9.50 ($2012), 175% of CC price Results follow…
