  9. Examples of Cross Area Responsibilities • Standard EOP-004-0 — Disturbance Reporting • 3. Purpose: Disturbances or unusual occurrences that jeopardize the operation of the Bulk Electric System, or result in system equipment damage or customer interruptions, need to be studied and understood to minimize the likelihood of similar events in the future. • 4. Applicability • 4.1. Reliability Coordinators. • 4.2. Balancing Authorities. • 4.3. Transmission Operators. • 4.4. Generator Operators. • 4.5. Load Serving Entities. • 4.6. Regional Reliability Organizations.

  10. Examples of Cross Area Responsibilities • Standard FAC-002-0 — Coordination of Plans for New Facilities • 3. Purpose: To avoid adverse impacts on reliability, Generator Owners and Transmission Owners and electricity end-users must meet facility connection and performance requirements. • 4. Applicability • 4.1. Generator Owner • 4.2. Transmission Owner • 4.3. Distribution Provider • 4.4. Load-Serving Entity • 4.5. Transmission Planner • 4.6. Planning Authority

  11. Examples of Cross Area Responsibilities • Standard IRO-004-0 — Reliability Coordination — Operations Planning • 3. Purpose: Each Reliability Coordinator must conduct next-day reliability analyses for its Reliability Coordinator Area to ensure the Bulk Electric System can be operated reliably in anticipated normal and Contingency conditions. System studies must be conducted to highlight potential interface and other operating limits, including overloaded transmission lines and transformers, voltage and stability limits, etc. Plans must be developed to alleviate System Operating Limit (SOL) and Interconnection Reliability Operating Limit (IROL) violations. • 4. Applicability • 4.1. Reliability Coordinators • 4.2. Balancing Authorities • 4.3. Transmission Operators • 4.4. Transmission Service Providers • 4.5. Transmission Owners • 4.6. Generator Owners • 4.7.Generator Operators • 4.8. Load-Serving Entities

  12. Preparation • Late Start • Company organization structure led to fractured approach • Attended SPP Compliance Workshop • Preparation for SPP and NERC Transmission Operation Audit in 2006 • Developed cross-area team to prepare all documentation • Corporate-Wide Standards Review • Critical Assets • Division of Standards

  13. Ongoing • Identifying Overlap/Gaps in Standards Management • NERC Standards Education • Training Program Enhancement

  14. Future • Develop job description and hire/transfer new Standards Administrator • Select Sr. Manager to oversee and manage CIP Standards • Incorporate Corporate-wide Standards, update meetings to ensure compliance without overlap • Determining level of compliance

  15. Lessons Learned • Start now • System Operator certification, training and documentation are essential • Internal and external training should be used • Identify responsible area(s) for each applicable standard • Document, document, document…… • Establish formal document management program including management review and approval
