## PJM's Perspective on Reliability – Summer 2004 and Beyond

- Karl Pfirrmann
- President -- PJM Western Region
- FERC Summer Reliability Workshop
- Cleveland, Ohio
- July 15, 2004

## PJM Profile Summer 2004 

- Summer transmission system performance anticipated to meet MAAC, ECAR and MAIN criteria
- Given normal weather and generation performance, assistance from neighboring regions should not be required. As per industry agreements, assistance is available from ECAR, MAIN, MAAC and SERC.
- Although a record PJM summer peak is anticipated, projected capacity resources have increased by 1465 MW since 6/1/03.
-     - Reservations for bulk power sales
-       out of PJM below historical averages
-     - Load response resources available
-       for 2.9% of total demand

## August 14, 2003 -- PJM Lessons Learned 

- Internal assessment process and incorporation of recommendations from NERC, MAAC Outage Review Team, ECAR Outage Review Team and US-Canadian Final Report
- Development of incident response program
-      - Emphasis on interregional response
-      - Multiple levels of communication within PJM and with
-         adjacent neighbors
- Enhancements to reliability coordinator function
-      - Assigned an operations engineer or power dispatcher as
-         the reliability coordinator
-      - Accelerated incorporation of reliability coordinator areas into
-         PJM energy management system model

## August 14, 2003 -- PJM Lessons Learned 

-   Visualization Tools
-     - Accelerated installation of dynamic map boards in Valley
-       Forge and Greensburg control rooms
-     - Increased visibility of neighboring systems
-   Ongoing coordination with MISO and neighboring regions to
-    enhance communications and systems, visualizations, and
-    monitoring/control

##  ComEd and AEP Integrations Enhance Reliability in Eastern Interconnection

- Larger RTOs provide broad perspective and cadre of reliability tools to mitigate potential for cascading electrical disturbances
- PJM's LMP-based congestion management system allows for redispatching of generation to relieve constraints
-         - superior to a TLR regimen
-         - PJM's energy market is the
-           fundamental tool used in
-           maintaining reliability
- In the longer term, PJM's planning processes provide for reliability-driven system improvements

## PJM/MISO Joint Operating Agreement and Reliability Plans improve Reliability at the Seams 

** **

- Assure that actions taken in one region only reinforce reliability or market operations in adjoining region
-  Improved interregional communications through
-   defined protocols
-  Continuous information exchange about conditions in
-   adjoining regions which may affect reliability
-  Timely exchange of detailed data and information
*(continued on next slide)*

## PJM/MISO Joint Operating Agreement and Reliability Plans improve Reliability at the Seams 

** **

-  Simultaneous coordination among PJM/MISO/affected
-   operating company to implement emergency
-   procedures and operating guides
-  Coordinated TLR Level 6 management at PJM/MISO
-   interface
-  Redispatch of generation to alleviate congestion on other
-   entity's grid
-  Respecting limits on both reciprocal and coordinated
-   flowgates

## Phased Implementation of Joint and Common Market (JCM) 

- JOA coordination procedures phase in as PJM and MISO markets develop together
- First phase provides for coordination with MISO operations to ensure appropriate congestion management
- Second phase coordinates day-ahead and real time constraint management once MISO market is operating
- Third phase implements enhanced market portal to provide common access and information for both RTOs
- Fourth phase integrates dispatch between two systems to manage congestion as if they were one system

##  Full Implementation of JCM will further enhance reliability in the Midwest

- PJM/MISO JOA is addressing reliability concerns by creating "work arounds" at seams to assure that separate markets work to bolster reliability
- Joint and common market contemplates coordinated single transparent energy market to eliminate seams
- Functioning of PJM's and MISO's state estimator models, along with day-ahead and real-time wholesale electricity markets data, produces pricing information necessary to induce generation to meet the reliability needs of the grid
