Iroquois Gas Transmission System, L.P. Electric/Gas Operations Communications Protocol
The purpose of this Electric/Gas Operations Communications Protocol ("EGOC
Protocol") is to enhance communication between Iroquois Pipeline Operating
Company as agent for Iroquois Gas Transmission System, L.P. ("Iroquois") and its
directly connected gas-fired power plant gas coordinators ("PPGC") as well as the
Independent System Operators ("ISO") for those PPGC's.
Ongoing communication is expected to occur between the electric and natural gas
industries. Regular communications occur between Iroquois and its PPGC's,
interconnected interstate pipelines, local distribution companies, and ISO's. Such
communications may occur via telephone call, e-mail, instant messaging, or fax.
Regional Transmission Operators, ISO's, and PPGC's should provide Iroquois with
contact information (e.g. e-mail address, phone number, etc.) by which Iroquois can
contact them, and should request to receive notices from Iroquois (critical/noncritical)
electronically (typically, via e-mail). Such parties should also provide
notifications to Iroquois via e-mail or telephone call.
Interested parties may also access Iroquois' Critical and Non-Critical notices, Planned
Service Outages, Available Capacity postings, etc. on Iroquois' publicly available
Informational Postings website at
Expected Hourly Flow
PPGC's should provide Iroquois with their expected flow rate for each hour of a gas
day by the beginning of each gas day via email. Submission of this email is for
communication purposes only. It does not constitute a nomination for hourly flow,
and Iroquois' acceptance of such email does not provide any guarantee that Iroquois
will accommodate the PPGC's desired hourly flow rates.
Iroquois allows PPGC's to flow at up to 120% of the uniform hourly scheduled daily
quantity for up to three consecutive hours twice in any twenty four hour period;
provided, however, that the second three hour period shall not begin less than eight
hours after the end of the first three hour period. Hourly flows that exceed this limit
shall be allowed on a "best efforts" basis only.
Iroquois does not support scheduling changes outside of the North American Energy
Standards Board Wholesale Gas Quadrant ("NAESB WGQ") nomination/scheduling
While Iroquois does not currently provide an hourly flow service, it reserves the right
to develop such a service in the future along with corresponding terms and
conditions and rates which appropriately reflect the additional facilities required to
provide such service.
Extreme Condition Communication
If extreme conditions exist on either the regional electric power system or the
regional natural gas grid which are considered abnormal (e.g. due to severe weather,
capacity deficiencies, energy emergencies, infrastructure failures, etc.), and these
conditions are either declared to be effective immediately, in the near future, or
projected within a forecast, then the potential exists for additional or enhanced
During extreme conditions on either system, communications will take place as
needed to ascertain the level of knowledge and understanding concerning system
status, problem duration, and identification of remedial activities or mitigation
Additionally, Iroquois may issue a critical notice which identifies constraints on its
system, the reasons for the constraints, and required actions when necessary. Such
notices shall be posted on Iroquois' Informational Postings website.
Another mechanism for industry coordination is the Electric/Gas Operations
Committee (EGOC), whose meetings Iroquois participates in. The EGOC was jointly
established by ISO-NE and NGA in 2004. It is comprised of representatives of both
the electric and natural gas delivery systems in the northeast: ISO-NE, on behalf of
the bulk electric power industry, and NGA (interstate pipeline companies, regional
LNG importers, and local gas distribution companies), on behalf of the regional
natural gas industry. The EGOC is jointly administered by ISO-NE and NGA.
Throughout the year the EGOC convenes on a periodic basis through meetings and
conference calls. The EGOC's purpose is to provide a forum for electric and natural
gas representatives to learn more about each other's systems and share information
on system operations, planning and procedures. The meetings and information
sharing abide by each industry's antitrust and information policies and only address
publicly available information. Meeting minutes are approved and publicly available.
