Liaison Reports
Agenda Item 5 - Load Shed Test Results
Karen Thomas (Southwest Power Pool) provided an update to the load shed test results that occurred
on 5/5/2016. Karen stated that the test will rotate every 7 weeks on Thursdays, and SPP staff will
contact TOP personal with pro-rated load shares for the load shed test. Karen stated that the 5/5/2016
test began at 0910 CPT and 21 TOPs were contacted with a 1017 MWs of load to shed across the
footprint, and the 21 TOPs responded with simulated amounts totaling to 1,070 MWs. Karen stated that
the test concluded at 0958 CPT and believes a blast call is necessary for these types of events over
individual calls to reduce response time. Karen stated that the next test will occur on 6/23/2016.
Agenda Item 6 - Voltage Task Force Update
Jason Tanner (Southwest Power Pool) provided an update to the activities occurring at the Voltage Task
Force. Jason stated that the VTF held a teleconference on 5-26-2016, and discussed a revision request
draft to modify solar and wind GIAs to require voltage control capabilities. Jason stated that the revision
request will likely have to be split into separate revision request due to the FERC NOPRs current status.
Allen Klassen (Westar Energy, Inc.) suggested adding language to allow for the FERC exemption until
FERC makes a ruling on the NOPR. Jason stated that he would return to the VTF with those suggestions.
Jason stated that the VTF discussed voltage settings for the phase 2 Variable Generation Integration
Study and hosted Powertech Labs at the meeting to receive stakeholder feedback before beginning the
study.
Agenda Item 7 - Variable Generation Integration Study
Jason Tanner (Southwest Power Pool) provided an update for the 2016 Variable Generation Integration
Study (VIS) and stated that the scope was approved by ORWG and is currently working through TWG
and ESWG for the project scope review. Efforts are also underway to finalize a consultant contract with
Powertech Labs. Jason stated that the consultant will analyze voltage stability for the SPP power system,
and develop Transient Stability models. Upon completion of the analysis the consultant will deliver
transfer limits for critical contingencies, P-V curves of critical load buses, identified voltage and thermal
voltage limits and associated curtailment of resource MWs. The target completion date for the SPP
Variable Generation Integration Study report is January 1, 2017.
Agenda Item 8 – FRCC Operational Challenges with Solar PV.
Eric Senkowicz (Florida Reliability Coordinating Council) provided an overview of the FRCC RC functions,
FRCC stakeholder structure, and provided an update from the FRCC Solar Task Force. Eric stated that
FRCC includes 50 registered entities 1 Reliability Coordinator, 10 Balancing Authorities, 14 Transmission
Operators, and 27 Generator Operators. Eric stated that the FRCC Solar Task Force is working to
consider transmission planning and grid operations needs to reliability support penetration of solar
generation within the FRCC region. Eric stated that based on the 2015 Solar Task Force survey
penetration levels are not expected to exceed about two percent of the summer peak load.
Agenda Item 9 – RR134 Outage Scheduler De-Rate Threshold.
Jason Tanner (Southwest Power Pool) presented the changes to RR134 Outage Scheduler De-Rate
Threshold. Jason explained the history leading up to the decision to use 25 MWs as the de-rate
threshold. Jason explained the changes to sections 2a, 2b, 2c, 2d, and 2e. Ron Gunderson (Nebraska
Public Power District) provided adjusted language for sections 2a, 2b, and 2c which the ORWG accepted
John Stephens (City Utilities of Springfield) moved to approve RR134 Outage Scheduler Derate
Threshold as modified, and Todd Gosnell (Omaha Public Power District) seconded the motion. The
motion was approved without opposition or abstention.
Agenda Item 10 – MPRR155 – Modification of OOME Rules.
Micha Baily (Southwest Power Pool) discussed MPRR155 and stated that the revision request was
designed to modify OOME instructions language into two categories: reliability issues and Emergency
Conditions. Micha stated that the revision request would allow SPP to move a resource for general
reliability that the market is unable to resolve, and would be able to utilize the OOME functionality in
the Markets systems to communicate dispatch instructions to resources. No reliability directive phone
call would be required. Micha stated that recently RR145 was approved which allows for the removal of
the MPRR155 language, and requested action from ORWG to withdraw MPRR155.
Jeff Wells (Grand River Dam Authority) moved to withdraw MPRR155 Modification of OOME Rules,
and Paul Lampe (City of Independence, MO) seconded the motion. The motion was approved without
opposition or abstention.
Agenda Item 11 – 2016 Flowgate Candidates and TRM Values.
Will Tootle (Southwest Power Pool) discussed the list of flowgate candidates that were approved by the
TWG to be added and removed. Will reviewed the list with the ORWG and discussed the naming
convention between the operations and planning models. Will recommended that ORWG take action to
approve the 2016 flowgate candidates and TRM values list.
Todd Gosnell (Omaha Public Power District) moved to approve the 2016 Flowgate Candidates and
TRM values as presented, and Allan George (Sunflower Electric Power Corporation) seconded the
motion. The motion was approved with 1 abstention (Empire District Electric Company) and no
oppositions.
Agenda Item 12 – TOP Posted Studies.
Will Tootle (Southwest Power Pool) discussed the TOP Posted Studies and what was being posted to the
FTP site. Will discussed the benefits for using the site over e-mail, and will stated that if access is needed
to send him an e-mail for assistance. Will stated that data will be housed on the FTP site for three years
before being removed, and Will asked for ORWG to review the posted studies and assess the details of
the data to determine if a standard format development would be needed.
Agenda Item 13 – 30 Minute Standardization of Ratings.
Derek Hawkins (Southwest Power Pool) discussed the proposed language for the short term emergency
rating revision request. Derek explained the changes in Criteria section 4.1.2.3 and discussed the
changes make in Appendix OP-1. Under section 4.1.2.3 Ron Gunderson (Nebraska Public Power District)
suggested modifying the language to “Each Transmission Owner shall provide a Normal, Emergency, and
Short-Term Emergency rating, calculated in accordance with the Transmission Owner’s facility rating
methodology and the following criteria, to the SPP Reliability Coordinator”. The group discussed
examples for how the market dispatches around normal emergencies, and 30 minute ratings.
ACTION ITEM: Create a document providing examples to illustrate how all ratings including short term
emergency ratings work.
Jeff Wells (Grand River Dam Authority) moved to approve the drafted language for the “30 Minute
Standardization of Ratings”, and to move forward with submitting the draft as an official revision
request. John Stephens (City Utilities of Springfield) seconded the motion, and the motion was
approved with 2 abstentions (Oklahoma Gas and Electric Co. and ITC Holdings) and 1 opposition
(Empire District Electric Company).
Bryn Wilson (Oklahoma Gas & Electric) Abstains
“My abstention was due to the need to further evaluate the “final” language, including for
compliance purposes. In addition, the language for this proposal needs to be clarified and should
follow the formal Revision Request process.”
Darrel Yohnk (ITC Holdings) Abstains
“ITC abstained from the vote on the proposed language changes for the upcoming RR posting to
update the Operating Criteria to include short term emergency ratings since the implementation
mechanism is not documented and by default is to dispatch the system in real time to the STE. In
essence, this just moves the “squishiness” of the ratings discussion from the emergency rating to the
STE placing reliability of the BES at greater risk. The default should be to continue to operate to the
emergency rating and use any extra room afforded by the STE solely for unexpected situations rather
than continually operating to the STE rating. This will ensure alignment between operating and
planning of the system.”
David Pham (Empire District Electric Company) Opposes
“This extra set of rating won’t gain consistency about the rating. It will create more work for
members and staff to maintain it. In real-time, it will create more confusion and coordination of this
rating wouldn’t be fun neither. Furthermore, we will just push the envelope out further and can
potentially accelerate the degradation the system over time.”
Agenda Item 14 – SPP Communications Protocol Redlines.
CJ Brown (Southwest Power Pool) discussed the SPP Communications Protocol document, and CJ
explained that SPP will not make modifications to the document. CJ explained that SPP will be prepared
to take operating instructions from TOPs and GOPs, but the SPP Communications Protocol document
will only be applicable to SPP operators issuing operating instructions.
Agenda Item 15 – Oscillation Event Using PMU Data.
Mike Nugent (Southwest Power Pool) discussed the February oscillation event and presented the results
that were recorded from the Little Spardra PMU. Mike stated that the oscillation lasted for 5 minutes
and impacted Bull Shoals, Table Rock, Norfork, Greer’s Ferry Dam, and Arkansas Nuclear One. Mike
stated that Unit 8 at Bull Shoals tripped at the height of the event, and oscillations stopped shortly
afterward, and Entergy saw much larger MW swings on their 500kV lines at ANO and Dell. Mike showed
the observed frequency, Voltage, and Current Magnitudes at Little Spadra. Mike also showed the 35
degree Phase Angle swing along the Little Spadra – Igo 161kV line. Mike stated that Entergy is engaged
and working with Washington State University to investigate the event using Entergy’s and SPPs PMU
and SCADA data.
Agenda Item 16 – Public Appeals.
Casey Cathey (Southwest Power Pool) stated that During the February ORWG Load Shed Test review,
SPP took an action item to confirm the Public Appeals process workflow. Casey stated that the Shift
Supervisor will notify the Manager of Operations, or designee, of situations that could require
notifications to the SPP Communication Department. Casey stated that SPP will coordinate emergency
communications and activities between SPP member entities including the Stakeholders and
neighboring BAs. Public Appeals to reduce demand will be managed using the SPP Corporate
Communications structure through the Transmission Operator’s established relationships with the
public. Casey also discussed public appeals in an EEA 2 and the message that would be communicated.
Ron Gunderson (Nebraska Public Power District) stated that he would like to see all loads notified during
public appeals.
Agenda Item 17 – Summer Assessment Sensitivity Review.
Jon Langford (Southwest Power Pool) presented the Summer Assessment Sensitivity Review. Jon
explained that the 2016 Summer Operations within the SPP Balancing Authority and Reliability
Coordinator footprints are expected to be normal with no forecast of extreme operational situations.
Jon stated that the transmission constraints and mitigations appear to be sufficient to maintain the
requirement of the operating criteria. Jon stated that our forecasted demand was 53,230 MWs with a
capacity of 67,649 MWs.
Agenda Item 18 – Eastern Interconnection System Inertia.
Casey Cathey (Southwest Power Pool) discussed the Eastern Interconnection System Inertia and stated
that in 2015 the NERC Board of Trustees approved several measures from the NERC Essential Reliability
Services Task Force. Casey stated that Synchronous Inertia at the Balancing Authority (BA) and
Interconnection level is a measure which was approved to be tracked at NERC starting in 2016. Casey
stated that since the SPP market went live SPP has seen a reduction in system inertia due to the
reduction of commitments. Casey stated that we need to understand where we are at and return to
ORWG to address any necessary policy concerns, or assess the need for additional products.
Agenda Item 19 – 2016 VIS Revised Scope.
Jason Tanner (Southwest Power Pool) presented the modified scope changes that reduced the number
of load pockets, and modified the Nebraska load pocket to only include Omaha and Lincoln. Jason
requested the ORWG take action to approve the presented version of the scope.
Dennis Sauriol (American Electric Power) moved to approve the 2016 VIS Revised Scope as presented,
and Craig Speidel (Western Area Power Administration) seconded the motion. The motion was
approved without opposition or abstention.
