Unscheduled Flow Administrative Subcommittee Report

Robin Chung

October 24, 2013

Anaheim, CA

2

• Currently short Path 66 Operator Representative – full roster is on WECC.biz

• Next Meetings are January 8 and 9, 2014, and then May 28 and 29, 2014

• 2014 meeting dates have been set to better address high USF activity in Spring and Summer

• August webinar scheduled to review Summer activity and prepare for October in person meeting

Membership and Meetings

3

Charter Discussion

• Yearly review required by charter

• Proposed changes:– Reaffirm UFAS role in collecting, reviewing

and analyzing USF event data– Remove training materials requirement– Remove dispute resolution language– Remove involvement in WECC budgeting

4

Charter Closed Door Policy

• UFAS believes it appropriate to have a closed door policy in their charter

• Must have closed door policy approval WECC BOD before bringing charter changes to OC for approval

• Charter will then go back to BOD for approval in its entirety.

5

UFAS Membership

• Current membership is equal number of Path Operators, Device Operators and At-Large members

• Unlimited terms

• No Reliability Coordinator representation

• With possibility of Qualified Path deletion, membership further limited

• What does the OC think????

6

Current Dues Calculation

• For 2012 dues calculation we require:– Import, Export, Generation & Load Data for

2008, 2009 & 2010– COPS hours for 2012– PST O & M Costs for 2011– Capped based on 1995 dues– Six different years being utilized in calculation!– 13 largest entities pay more– Only WECC members are charged

7

Proposed Calculation Methodologies

• Option 1: By NERC Registration

• Option 2: EIA-714, EQR or comparable WECC data request

• Option 3: Hybrid – Weighted NERC Registration

8

By NERC Registration

• Divide PST costs equally by individual NERC functional entity registration

• One charge per functional registrationo Excluding RC, RSG and IA

• Would capture all entities in WECC, not just WECC members

• Simplest and least cost to implement by far

9

Cost Per Registration - 2012

• $3858 per registration

• Example: If an entity is registered as TO, TOP and GO, it would owe $11,574

10

EIA-714, EQR or Comparable WECC Data Request

• Would need comparable load, generation, import and export data from all WECC entities

• Data might currently reside in existing reports such as 714 and EQR

• Not all WECC entities file all reports. Specific WECC report would need to be developed for those who don’t file

• Once reporting form developed, process would have to be developed to assess charges

11

Hybrid – Weighted NERC Registration

• Utilize NERC registry information and weight with Option 2 data

• Weight entities based on utilization of transmission outside of their immediate BA– 50% on registration (base amount) and 50%

based on weighted utilization– Various methods discussed on how to weight – Accuracy of weighting dependent on

methodology chosen

12

Possible Weighting Methodologies

• Sum of imports and exports– Annual– Hourly

• Net imports/export– Annual– hourly

• Load versus generation

• Other possible methods?

13

Possible Alternative Weighting Methods

• Data would be collected automatically through webSAS (programming costs associated)

• Go back and look at tag data• Need to determine which portion of tag

information to utilize (which entities?) • Need to determine time frame (entire year,

during COPS, during USF?)• MWh’s used• Gets complicated very fast!

14

Recommendation

• Option 1 – By NERC Registration• Recognize it’s simplest and easiest to

move forward• Realize there may be little cost causation

relationship between registration and USF• Has been discussed for years – let’s move

forward and fix the problem!• Can always revise after RCCO and ECC

is settled

15

2013 Path 66 Update

• Continuing to look at Path Utilization• Trend of lower scheduled usage versus path

limit, fewer events, lower step events continues in 2013

• Lower Actual Utilization so far in 2013: 69.4% compared to 74.04% in 2012

• UFAS refining this data and starting to correlate percentage of path utilization to USF events

16

Path 30 Investigation

• 6 events from 2012 and 7 events from first part of 2013 have been chosen, data request has been fulfilled

• UFAS continues to have data sharing issues, several members of the subcommittee cannot see the data

• Temporarily halting this sort of event analysis until all members can view the data

17

15 Minute Scheduling

• Change Order 34, detailing changes to webSAS for 15 minute scheduling, expired October 2012

• WECC staff expediting revised Change Order and implementation

• Risks of not implementing by November 2013 are minimal

18

FERC Filing Update

• Filing both Unscheduled Flow Reduction Guideline and updated regional reliability standard IRO-006-WECC-3

• Cut by NERC priority, off-path, then on-path schedules via 16 “bucket” methodology

• Will result in fewer over all MW cuts and tag curtailments to reduce flows

• webSAS change order has been implemented with OATI

19

Other Meeting Activities

• Data share discussion is ongoing• Continued coordination with the Enhanced

Curtailment Calculator Advisory Task Force• Discussions regarding the CISO/PAC EIM

Market and its impact on Unscheduled Flow Mitigation

20

• There are currently no Paths or Devices pending for disqualification

• Path 22 may be subject to disqualification in October 2013

Path and Device Qualification Status

21

• Plan Year 19 (CY2013) activity as of July 2, 2013 has 748 hours of Coordinated Operations of Phase Shifters (COPS) with 227 hours of contributing schedule curtailments

• Total of 14,506 MWhs of Unscheduled Flow relief was provided by curtailments

• Primary users were Path 30 and 66• 29 hours of competing path events to date, primarily

between Path 30 & 36 and Path 30 & 66 • UFAS investigating competing Path 66/Path 30 events
