TO: ALL TENNESSEE CUSTOMERS
RE: UPDATED TGP SCHEDULED OUTAGES
This notice is an update of the 2017 planned outages and maintenance
activities on Tennessee Gas Pipeline.
The Outage and Maintenance schedule is available in an Excel
spreadsheet format which may be found in DART.
Some projects may reduce capacity to a level below anticipated
demand (nominations), or require taking individual meters out of
service.
For each project, based upon anticipated demand, the highest
level of service Tennessee expects to be impacted is noted.
Unless noted otherwise, all impacts are in the Supply to Market
direction.
Projects may be added, altered, delayed or canceled. Tennessee
will provide updates by posting revisions on a weekly basis or
more often if necessary.
Projects revised or added since the last posting are preceded
by ***. Within the Excel Spreadsheet and Adobe Files, revisions
are highlighted and an asterisk has been added to the "Revised"
column.
Unless otherwise noted, all listed meters will be physically shut
-in for the duration of the project.
Unless otherwise noted, all scheduled dates represent gas days
as defined in the Tennessee Gas Pipeline tariff to mean a period
of twenty-four consecutive hours, beginning and ending at 9:00
a.m. (Central Clock Time).
