2007 Transportation Loss Factor

Effective January 1, 2007, the five-year average of gas unaccounted for = 1.380%. The transportation loss factor = .98620, which is calculated by taking one minus the percentage of gas unaccounted for (1 - .01380 = .98620). For billing purposes, the transportation loss percentage changes on a calendar year basis.

Peaking Service - Reminder

Peaking Service is a new ancillary service that is available during the winter period, November 2006 through March 2007. Please note that the nomination process and deadlines for Peaking Service differ from what is in place for gas supplies that you arrange for delivery into our City Gates. Therefore, it is important to review how Peaking Service nominations are submitted on-line and in what timeframes that they need to be submitted to Yankee Gas.

Submitting Peaking Service Nominations

Please submit nominations for Peaking Service at the Ancillary Services Nomination site, which is located at the following link,

For step-by-step instructions on entering a nomination for this service, please refer to the attached file that accompanies this newsletter. Any questions, please contact Marie Heath at or 860.665.6228.

Nomination Deadlines

Here are the specific timeframes for submitting nominations for Peaking Service.

  • Subsequent nominations (next day) are due by 8:30 a.m. EDT on the prior business day.
  • For holidays and weekends, nominations are due by 8:30 a.m. EDT on the prior business day.
  • Nominations for a multiple day period, weekends or holidays, must be the same volume for each day during this period.
  • No intraday (same day) nominations are accepted.

Helpful Guidelines

  • Daily nominations cannot exceed the designated Maximum Daily Peaking Quantity (MDPQ).
  • On an individual pool basis (for firm service Pool 1 and Pool 2), a portion or all of the MDPQ nominated volume will count as a full day out of the 20 days that is available during the winter season.
  • In the event that the Web site is down, please follow the alternative nomination procedure by faxing the completed nomination form to Gas Nominations at 860.665.6296.

Operator Report – Layout Changes

  • The Peaking Service Reservation volume (in CCF units) appears in the header of the Operator Report by pool. This volume is representative of the reservation volume that will be billed monthly from November 2006 through March 2007.
  • Both the daily Peaking Service Nomination volumes, which are submitted in MMBTU units, and the daily Peaking Service Delivery volumes (converted to CCF and adjusted for Transportation Losses) will appear on page one of the Operator Report.
  • For purposes of daily balancing and daily cash out, daily Peaking Service Delivery volumes are added to the daily total delivered volumes.
