I am not sure you are the correct person to contact about these questions but I am hoping you can help or at least point me in the correct direction. I am looking at three different pieces of data - Index of Customers, Tariff information and Capacity Release data. I am having trouble understanding the way your pipeline works and I am hoping someone will be able to help. One of the major questions I have is why the rate schedules differ so much between these three pieces of data, IOC lists the rate schedules on contracts as TF_M_11_3, TF_M_4_10, or TF_F_1_12. Tariff lists the schedule TF with various rates under it, TF_12 base, TF_12 variable and TF5 (all under the market to market heading), TFF under the Field to Field /market Demarcation heading, etc. , and in capacity release I see rate schedules that look different still, TF5-TF5, TF7-TFF, TF2-TF12, TFX1-TFX Mkt Apr-Oct. I am trying to reconcile the differences and I can get a little ways but then I run into problems. For instance, in the IOC, I am assuming TF_M_11_3 means TF rate- Market to Market- flowing from Nov-March. But then I see a contract that has the TF_M_11_3 rate schedule that flows from April thru Oct (according to effective and expiration dates of the contract) and I get confused again. I can correlate some of the capacity release rates to tariff, TF5-TF5 corresponding to TF5 under the TF rate, but then I get to TF7-TFF and I am not sure where the TF7 comes from or what it correlates to. I know there must be some way to look at all this together, but I am at a loss to figure it out, which is why I am asking for your help. I have never nominated on your pipeline, but instead am just doing data collection and analysis. There are more questions I need to have answered and would like to be able to contact someone so that I can talk with them and gain an understanding of how your pipeline works. Could you please give me a call or direct me to whom I need to speak? I can be reached at 720.548.5470. One more thought - is there perhaps a "handbook" that I would be able to read that might answer some of these questions for me, perhaps a nomination guideline that you might give to a new trader/scheduler? If so, please mail me a copy to 3333 Walnut Street Boulder, CO 80301. Thank you so much for you help in this! I appreciate anything you can do for me.
