13. N IXON P EABODY LLP Memorandum of Understanding – 12/20/05 Commitment to address the challenge of climate change while increasing energy efficiency investments and stimulating emerging clean energy technology markets 2009-2015: stabilize CO 2 emissions from regions power plants at current levels By 2019: 10% reduction in CO 2 emissions from regions power plants

14. N IXON P EABODY LLP RGGI Model Rule – August 15, 2006 CO 2 budget unit = at any time on or after January 1, 2005, serves electricity generator with a nameplate capacity equal to or greater than 25 MWe Program begins 1/1/2009 (or date unit commences operation) State regulatory agency issues CO 2 budget permit Compliance Certification Report due by March 1 of year following control period CO 2 Allowance Tracking System

15. N IXON P EABODY LLP RGGI – Issues Allowance Allocation –Auction v. Giveaway? –25% of allowances must be to consumer benefit or strategic energy purpose –Early reduction CO 2 allowances –Voluntary renewable energy market set-aside Voluntary limited industrial exemption set-aside –Banking allowed Leakage

16. N IXON P EABODY LLP RGGI – Offsets CO 2 equivalent emission reductions or carbon sequestration Real, Additional, Verifiable, Enforceable, Permanent Offset project types (must commence after 12/20/05) –Landfill methane capture and destruction –Reduction in SF6 –Carbon sequestration due to afforestation –Reduction/avoidance of CO 2 emissions from natural gas, oil or propane end- use combustion due to end-use energy efficiency –Avoided methane emissions from agricultural manure management operations

17. N IXON P EABODY LLP RGGI – Offsets (contd) If average price of allowance < $7.00, offsets may be used from across the US; 50% discount from outside RGGI region; up to 3/3% of generators emissions If average price of allowance > $7.00, offsets may be used from across North America at 1:1 ratio; up to 5% of generators emissions (Offset Trigger) If average price of allowance = $10.00, offsets may be used from international projects; up to 20% of generators emissions (Safety Valve Offset Trigger)

18. N IXON P EABODY LLP RGGI – Next Steps Governors of participating states have agreed to propose regulations by 12/31/08 Regional Organization (RO) –Administration of Allowance Auctions –Emission and Allowance Tracking –Guidance Documents NY – 12/5/06 Pre-Proposal Draft www.dec.state.ny.us/website/dar/preproposal.htm

19. N IXON P EABODY LLP AB 32 – California Global Warming Solutions Act of 2006 (9/27/06) Reduce GHG emissions to 1990 levels by 2020 By 2050, GHG emissions to 80% below 1990 levels CARB must develop regulations and market mechanisms Adopt mandatory reporting rules for GHG sources

20. N IXON P EABODY LLP Examples from Other States NM: Executive Order (12/28/06) - Reduce GHG emissions to 2000 levels by 2012, 10% below 2000 levels by 2020 and 75% below 2000 levels by 2050 AZ: Executive Order (9/8/06) - Reduce GHG emissions to 2000 levels by 2020, and 50% below 2000 levels by 2040.

21. N IXON P EABODY LLP Conclusions CO 2 regulation is a reality, at least locally and regionally National regulation is a question of when, not if Owners of existing power plants should push for broad cap and trade systems, rational allowance allocations, new source set asides, and a wide array of offset opportunities Developers of new coal-fired power projects early on must develop strategies to deal with CO 2 in the permitting process
