Clean Power Plan Clean Air Act 111(d) and 111(b) Rule A Quick Comparison of What Changed Anda Ray Environment, VP and Chief Sustainability Officer August 4, 2015 San Francisco, CA
Clean Air Act (CAA) Final Rules September 20, 2013 Clean Air Act (CAA) 111(b) proposed rule issued Applies to new, modified and reconstructed generating units June 2, 2014 Clean Air Act (CAA) 111(d) proposed rule issued Applies to existing sources (aka Clean Power Plan ) Over 4.3 million comments August 3, 2015 Final Rules issues: CAA 111(b) and 111(d), and Federal Implementation Plan for 111(d) 2
Initial Reflections on the Final 111(b) Rule for New Sources Less Stringent Emissions Limit Coal: 1000 lb/mwh-gross 1400 lb/mwh Gas: 1000 lb/mwh-gross (no change) CCS is not required, but reaffirmed it is a Best System of Emissions Reduction (BSER) Other Compliant technologies might now include options without CCS Ultra-super critical coal with gas co-firing IGCC with partial separation of CO 2 or gas co-firing Citing high costs of 50% carbon capture required by the proposed rule Less Stringent Emissions Limits 3
Initial Reflections on the Final 111(d) Rule for Existing Sources Building Blocks The Best System of Emission Reduction (BSER) Coal Units Heat Rate Improvements NGCC Units Redispatch Expansion of Renewable and Nuclear Energy Use of Energy Efficiency Heat Rate NGCC Nuclear Power Renewable 6% Range: 2.1%, 2.3% and 4.3% (~ 30% to 50% lower) Re-dispatch Coal to Existing NGCC @ 70% CF Nameplate 75% CF Net Summer New NGCC is not a BSER for direct replacement of coal [New NGCC is under 111(b)] Conversion of Coal plant to Gas plant is a compliance option Biomass (co-firing or other) still not considered No longer used in setting goals (Not a BSER) New, in-construction and uprates can be used in compliance New renewable energy plays larger role in goal setting optimized costs Clean Energy Incentive Plan (CEIP): Allowances or Emissions Reduction Credit Incentive for early adoption Emissions Reduction Credits (ERCs) 2020-2021 Energy Efficiency No longer used in goal setting, but still valid for compliance Incentive for early adoption. ERCs accrued in 2020-2021 After State Plan submitted Additional incentives for investments in low-income communities 4

Selected State Comparison Needs More Analysis! Goals tightened in carbonintensive states Goals loosened in less carbonintensive states Changes in State 2030 Goal Proposed Rule (lbs/mwh) Final Rule (lbs/mwh) West Virginia 1620 1305 North Dakota 1783 1305 Kentucky 1763 1286 Washington 215 983 California 537 828 Arizona 702 1031 More Narrow Range of State Emissions Note: No targets for Alaska, Hawaii, Puerto Rico, Guam Will come later 6
Clean Power Plan Cost and Benefits Co-Benefits (Particulates, etc.) Climate Benefits (Includes Social Cost of Carbon) Summary Monetized Cost & Benefits in 2030 (billions of 2011 USD) Proposed Rule Final Rule $23 to $62 $11 to $34 $30 $20 Power Sector Costs ($7) to ($9) ($5) to ($8) NET $46 to $84 $25 to $45 Benefits Decreased, Primarily due to Changing Assumptions 7
Initial Reflections on the CAA 111(d) Federal Plan Proposed 90-day Comment Period Plan for final rule by summer 2016 EPA would promulgate a federal plan in any state that does not submit an approvable plan and then implement the plan on power companies. EPA is proposing and seeking comment on: 1. A rate-based federal plan for each state based on model rule 2. A mass-based federal plan for each state based on model rule EPA intends to finalize a single federal plan type (rate or mass) based on comments. 8

Final Rule Instant Take Away Evolution of the Final Plan 1. Higher Emissions Rates for New Fossil 111(b) 2. Carbon Reduction Goal is higher 111(d) 3. New NGCC s now excluded from rate-based plans 4. Nuclear out for goal setting, but some role for compliance 5. Safety Valve for Reliability included. 6. Energy Efficiency no longer part of target, but still part of compliance 7. Guidance on trading credits across state lines Trading Ready 8. 2020 date extended to 2022 and glide path for future years more smooth Slows the Dash for Gas 9. Mass approach gets more full billing and EPA support Compliance Sept 6, 2016 Sept 8, 2018 2020-2021 2022-2029 10 Turn in State Plan Final State Plans Due Opportunity for Emissions Reduction Credit Three Multi-year Step Downs
