Update on the Gas Usage
Profile Project
Reliability Subcommittee
June 1, 2017
Purpose &
Key
Takeaways
Purpose: Provide project
update and follow-up to April 6
RSC discussion
Key Takeaways:
• Project is an incremental step building on
the direction and success of past MISO
gas-electric coordination efforts
• Helps promote reliability by communicating
aggregated data in a way that’s useful for
operators of gas pipelines/utilities in the
short-term operating window
• Project to begin by end of 2017
Gas-electric coordination continues to be a
priority, most notably for maintaining reliable
operations during peak conditions
•
•
MISO has described its gas-electric objectives, past
advancements, and current projects*
There are significant increases in MISO gas-fired
generation, as reflected in history and projections
−
•
Drivers: fuel economics, coal retirements, new gas
capacity, increasing renewables (and variability), and
overall low reserve margin environment
•
Gas is critical in MISO for increased baseload capability
and, importantly, for reserves, swing, and ramp
Since the April 6 meeting, stakeholders provided
valuable feedback which MISO used to further refine the
approach for the Gas Usage Profile project

*See
RASC presentations November 30, 2016, and January 11, 2017
MISO is initiating a gas usage profile program
with three gas pipelines/utilities in 2017
•
Each gas pipeline/utility will receive a customized daily summary of
gas usage forecasts based upon the gas generators connected to
their system and the associated MISO day-ahead clearings
‒
Forecasted daily totals and hourly profiles
•
MISO will focus on coordinating with gas pipelines/utilities to develop
the most meaningful gas usage aggregations for their gas systems
•
Illustrative example for a gas pipeline (values in MMBtu):

Sharing non-public operational information is
consistent with FERC Order 787*. Profiles will
provide benefits that promote reliability
•
To protect non-public information, MISO will execute
nondisclosure agreements and notify gas pipelines/utilities of
existing FERC rules which enforce protection of non-public
information
•
Gas usage profiles will help gas pipelines/utilities forecast gas
demand as part of their daily preparations for system flows
•
Gas usage profiles improve communication around system
conditions and provide further opportunities for advanced
dialogue between electric and gas operators
•
Most relevant in severe weather or contingency conditions
when coordination matters the most

*Please see appendix for additional information
MISO plans to begin sharing gas usage profiles
by the end of this year
•
MISO did not receive stakeholder comments specific to
the proposed tariff language which would enable sharing
of non-public information with gas pipelines/utilities
•
MISO filed proposed tariff revisions with FERC on May 5,
2017: Docket No. ER17-1556-000

Thank you. For any follow-up, please contact:

Comments from gas pipelines/utilities
−
Hourly gas usage forecasts allow gas pipelines/utilities to
forecast large swings in generator demand
−
Pipelines could use this information to help structure line
pack and enhance compression for reliable operations
ahead of time
Comments from RTOs
−
Gas usage profiles were instrumental in managing
contingency events
−
Gas usage profiles help enable open operational
discussions with gas pipelines/utilities
This project is consistent with FERC Order 787 to
promote reliability
The goal of Order 787 is to promote reliability of both electric and natural
gas systems
“Communication between transmission operators serve a valuable and necessary purpose
to help ensure reliability on both systems.”
• “…interstate natural gas pipelines and electric transmission operators need other
operational information, including non-public information, in order to reliably manage the
operations of these systems.”
•
§ 284.12 Standards for pipeline business operations and communications
•
(b)***(4) Communication and information sharing among pipelines and public utilities.
• (i) A pipeline is authorized to share non-public, operational information with a public utility,
as defined in § 38.2(a) of this chapter or another pipeline covered by this section, for the
purpose of promoting reliable service or operational planning.
• (ii) Except as permitted in paragraph (b)(4)(i) of this section, a pipeline and its employees,
contractors, consultants, and agents are prohibited from disclosing, or using anyone as a
conduit for the disclosure of, non-public, operational information received from a public
utility pursuant to § 38.2 of this chapter to a third party or to its marketing function
employees as that term is defined in § 358.3(d) of this chapter.
