3 Reliability Challenges White Paper First step in operationalizing the Integrated Reliability Assurance Model Culmination of conversations over last 4 months Staff developed, now seeking stakeholder feedback Feeds development of Work Plan Priorities 3 W ESTERN E LECTRICITY C OORDINATING C OUNCIL

4 Changing Resource Mix Potential challenges … Ensuring resource adequacy Considering a wide range of drivers Accounting for system composition, e.g., resource location 2013 Capacity and Energy Production Western Interconnection (U.S. only)

5 Retirement of Conventional Generation Potential challenges … Planning for hydro limitations Re-evaluating nuclear’s role Maintaining Essential Reliability Services Accounting for local, state, and federal policies 2013 Added and Retired Capacity (MW)

6 Natural Gas-Electric Interdependencies Potential challenges … Understanding supply issues Reconciling differences in scheduling practices Planning for and operating during severe weather events 2012 Natural Gas Consumption by Sector

7 Changing Load Composition Potential challenges … Managing high levels of new types of demand, e.g., PHEV Accounting for demand- related policies, e.g., energy efficiency Leveraging demand control and reduction mechanisms, e.g., demand-side management 2012 Electricity Consumption by Sector (Western Interconnection U.S. only)

8 Effects of Changing Climate Potential challenges … Managing the operational impacts from changes in – Temperature – Extreme weather events – Wildfires Planning for resource adequacy impacts Coping with immediate and long- term effects of drought Responding to policies addressing climate change Western Climate Regions

9 Integration of Variable Generation Potential challenges … Understanding the drivers Managing uncertainty Balancing variability Wind and Solar Capacity Additions (MW)

10 Balancing Variability Potential challenges … Planning for flexibility Holding Operating Reserves Diversifying variability Implementing scheduling changes Example Wind and Solar Base-Load Ramping Scenario Load & Net Load (1,000 MW) Wind & Solar (1,000 MW) 0:006:0012:0018:0024:00

11 Distributed Generation Potential challenges … Managing variability Improving visibility of DG resources Coordinating control of DG resources Reconciling practices and standards on response to faults

12 Situational Awareness Potential challenges … Increasing use of real-time tools Coordinating information and data exchange Expanding external visibility in models Improving consistency and quality of next-day studies Use of Situational Awareness Tools (% Entities Surveyed in 2014)

13 Equipment Failure Potential challenges … Reducing outages caused by equipment failure Minimizing the impact of equipment failures Automatic Transmission Outages Caused by Equipment Failure

14 Protection System Reliability Potential challenges … Evaluating and managing the interaction of RAS Ensuring proper relay settings Reducing relay misoperations 2013 Misoperations by Cause

15 Operational Practices Potential challenges … Evaluating trends in operational practices Identifying best practices Promoting adoption of practices across diverse entities

16 Cybersecurity Potential challenges … Securing assets and managing access Detecting potential threats Balancing benefits of technology with increased exposure to cyber risks Identifying significant vulnerabilities on regional/Interconnection-wide basis

17 Physical Security Potential challenges … Ensuring proactive approach to physical security Securing grid against a range of threats Implementing CIP Managing costs Addressing accessibility of assets Total Physical Attack1269 Physical Attack – Vandalism Suspected Physical Attack Suspicious Activity21 Total Physical Security Electric Disturbances (DOE Form OE-417)

18 High-Impact Low-Frequency Events Potential challenges … Preventing coordinated cyber and/or physical attack Mitigating potential impacts of geomagnetic disturbances Identifying potential impacts of a pandemic Predicting and mitigating impacts of large-scale disasters Balancing probability v. risk in investment decisions

19 Impacts of State Policy and Regulation Potential challenges … Identifying policy and regulatory drivers Ensuring policies and regulations consider reliability concerns Emphasizing interconnected nature of the grid Western Climate Regions

20 EPA 111(d) Clean Power Plan Potential challenges … Evaluating the reliability impacts Accounting for flexibility in implementation EPA 111(d) Compliance Building Blocks Building Block 1: Coal Plant Efficiency Improve the heat rate of coal-fired power plants by 6%. Building Block 2: Increased Gas Use Increase utilization of gas plants up to 70% capacity factor. Building Block 3: Renewables and Nuclear Increase renewable and nuclear generation. Delay or cancel nuclear retirements. Building Block 4: Energy Efficiency Increase energy efficiency to reduce demand by 1.5% per year.

21 Functional Model Potential challenges … Aligning registration with the Functional Model Addressing gaps in Planning Coordinator registration Evaluating role of the Path Operator Coordinating seams issues between registered functions Count of Selected Registered Entities in the Western Interconnection Registered Entities# Balancing Authority (BA)37 Generation Operator (GOP)241 Generation Owner (GO)247 Load Serving Entity (LSE)121 Planning Authority (PA)31 Reserve Sharing Group (RSG)3 Resource Planner (RP)56 Transmission Operator (TOP)65 Transmission Owner (TO)97 Transmission Planner (TP)47 Transmission Service Provider (TSP)37

22 Workforce Potential challenges … Managing the workforce retirement transition Addressing the reduction in knowledge capital Managing cognitive overload created by increasing volume of tools, information, etc.
