BAL-002-2/EOP Update
Rich Hydzik, Avista
NWPP RSGC Vice-Chair

2. BAL-002-2(i) As Is

3. BAL Under Ballot

4. BAL-002 Both Versions
BA may deploy Contingency Reserve to meet load obligations under Energy Emergency Alert – EEA 3
If BA or RSG is deploying Contingency Reserve under EEA 3
Must meet R1 (DCS) if available Contingency Reserve equals or exceeds Most Severe Single Contingency
Is not subject to R1 if available Contingency Reserve is less than Most Severe Single Contingency
BA(s) must be following emergency Operating Plan

5. EOP-011-1 R2 Applicable to BA, RC, TOP (not RSG)
Establishes requirements of Operating Plan
Attachment A defines Energy Emergency Levels
Deploy Contingency Reserve to meet load
This is the transition from EEA 2 to EEA 3
EEA 3 – Firm Load interruption is imminent or in progress
The energy deficient Balancing Authority is unable to meet minimum Contingency Reserve requirements (EOP-011-1)

6. How Do BAL-002/EOP-011 Interact?
BAL-002-2(3) is applicable to BA or RSG
BAL-002-2(3) R2 requires BA or RSG to determine MSSC and CR obligation
BA CRO can be determined by BA or RSG (if BA is a member of RSG)
EOP is applicable to BA, RC, TOP
EOP R2 requires BA to develop Operating Plan(s) to mitigate Capacity and Energy Emergencies

7. How Do BAL-002/EOP-011 Interact?
Single BA
EEA 2 to EEA 3
BA deploys CR to meet load
CR available remains above MSSC
BA required to meet DCS (R1)
CR available falls below MSSC
BA no longer required to meet DCS (R1)

8. How Do BAL-002/EOP-011 Interact?
BA is part of a Reserve Sharing Group
Participating BA moves EEA 2 to EEA 3
BA deploys CR to meet load
RSG CR available remains above MSSC
RSG required to meet DCS (R1)
RSG CR available falls below MSSC
RSG no longer required to meet DCS (R1)

9. BA Participating in an RSG Short of Contingency Reserve
RC Data Request from BA includes
Contingency Reserve Obligation (CRO)
Contingency Reserve Available (CRA)
CRA >= CRO
All is good
CRA < CRO
BA is using CR to serve load
EEA 2 to EEA 3 condition
RSG still meeting MSSC?

10. BA Participating NWPP RSG
RSG contains six “zones”
Each zone has an MSSC
CRO is monitored to cover MSSC
CRA consists of
CR in zone
CR deliverable from adjacent zones
CRO is reallocated in zone if CRA<MSSC
Reallocation of CRO continues until CRA>MSSC
CRO and CRA values are supplied to RC by each BA

11. BA Participating NWPP RSG
Each Zone is monitored
Quantities monitored in real-time
MSSC
CRA
Transmission deliverability
CRO
CRO in each zone must exceed MSSC
Typically it is 3/3 rule for BA’s
Transmission deliverability may raise CRO for zone BA’s

12. BA Participating NWPP RSG – WA, OR, MT Zone
AVA
BPAT
CHPD
DOPD
GCPD
GRID
GWA
NWMT
PACW
PGE
PSEI
SCL
TPWR
WAUW
WWA
MSSC = 1150 MW
CRO = 3/3, sum must exceed MSSC
CRAzone = CRAAVA + CRABPAT + … + CRAWWA
If CRAzone <= MSSC
Calculate shortage
Reallocate CRO to meet MSSC
CRO increases for everyone until CRAzone exceeds MSSC
If a BA is short, and CRAzone drops below MSSC, CRO is allocated among other members to meet MSSC
If one BA in the Zone has adequate CRA, zone is meeting MSSC!

13. BA Is Short Contingency Reserve
Other BA’s are allocated CRO if necessary
RSG Program handles allocation in real-time
BA CRO shortage
Most likely not an issue for DCS reliability
Good indication of balancing issue
What is BA doing to correct issue?

14. NWPP Reserve Sharing Real-Time Status
How can we improve RC visibility?
How can we improve RC situational awareness of CR?
How can we separate DCS reliability issue from temporary balancing issues?
Questions?
