Gas / Electric Coordination



FERC Request for Comments (AD12
-
12):


FERC involvement to ensure better coordination & communication?
(
Especially during cold weather and emergency events to maintain reliability.)


What, if anything, should be delegated to NERC, NAESB or others?


Address at regional level? With FERC oversight? Monitor/enforce how?


New pipeline and storage services and pricing structures for generators?


Different views for organized markets vs. bi
-
lateral markets?


Electric generation will likely change gas flows


should FERC address?


Harmonize “days” and intra
-
day and preschedule trading/scheduling?


Impact of coal and oil
-
fired generation retirements?


Should FERC modify standards of conduct to assure greater
coordination? Only in emergencies? For planning?


Should FERC take a “basket” approach in addressing these? What are
the appropriate baskets?


Electric reliability standards with respect to firm fuel supply?


Enhance FERC process for infrastructure to ensure adequacy?

AGA Response to AD12

12

Overarching goal should be preserve and enhance reliability for
all customers!


And there was nearly universal agreement in tackling the issues
regionally.



Regional stakeholder process:


FERC should convene technical conferences at both the national
and regional levels


Commissioners should participate


Enhance understanding across both markets of day
-
to
-
day
operations and the longer
-
term impacts on operations, planning
and costs


Draw on regional experience and expertise of all stakeholders


Understand each region’s current efforts to enhance
coordination; expand on those efforts, as possible

Regional Response

So….What has the Pacific Northwest discussed?



Enhance communications and coordination:


Understand operational vulnerabilities


Collaborate on long
-
term planning efforts


Develop processes that will endure


Determine service needs and work with service providers to
develop appropriate services:


Expectations that services will be developed without market
support is unrealistic


Gas utilities have operated under this mode for years…it works,
but we collectively need to have a handle on what we need and
how we expect to operate


The Pacific Northwest had a bit of a head start…

NWMA Objectives



Communication! Communication! Communication!


Emergency Planning Committee:


Meet at least twice a year



Fall


Discuss upcoming winter outlook and issues


Spring


Review previous winter and effectiveness of NWMAA


Maintain key contact list for all participants


Coordinate periodic tabletop emergency exercises


Manage NWMAA


Develop and maintain protocol for region
-
wide communication during
emergency events

convened by affected pipelines or other system
operators



Implemented a service (
NotiFind
) that facilitates emergency notifications by phone,
text and email

Communication! Communication! Communication!


Keeping emergency contact lists fresh and maintaining a ready
capability to instantly reach out (email, text, phone messages, etc.)


Relevant participant representatives must be able to communicate in
an emergency to fully implement optimal solutions:


Standards of conduct issues if transmission personnel are on a
call with marketing personnel? Need to be addressed?


Commercial operations folks must be involved as should those
that understand critical electric transmission issues, due to the
convergence of power and gas in the region


Conducting relevant drills and exercises


Conducting effective communications during emergencies

Longer
-
term Reliability Initiative

Initial Tasks:


Primer on status of industries


inventory pipeline capacity, generating
capacity, generation needs, standard vocabulary


White paper comparing planning perspectives


planning margins, design
days, contingency planning


BPA white paper on gas/electric interdependencies


Perform scenario analyses to establish system stress points


Inventory work being done by others, to ensure efficiency of effort


Stay plugged into FERC/NERC progress


Eventual Work Product:


Identify critical issues such as the need for pipeline and/or gas storage
expansion, reliability of natural gas compressor stations (and other critical
infrastructure), single points of failure, and necessary changes to operating
rules and/or regulatory framework


Present analyses, conclusions and recommendations to the NWGA & PNUCC
boards, and to regional policy makers and stakeholders
