5. 5 Growing Market Potential for PV Rising electricity prices –Global demand for coal and natural gas –Popular opposition to coal plants –Cap-and-trade system may increase electricity prices by 20% (assuming $40/ton carbon) Falling tech and project costs Favorable trend in policy, e.g., –Renewable Portfolio Standards –Net metering and interconnection –Federal cap-and-trade system’s distribution of allowances / auction proceeds to renewable energy 2

6. 6 U.S. PV Installation Growth MW installed 2000:17 MW 2006:141 MW (+31%) 2007:259 MW (+83%) 2008: 491 MW (+90%) 2009: 913 MW (+86%) 2010: 1590 MW (+74%) More than 60% large commercial Sources: US PV grid-tied module use 2006 IREC and Larry Sherwood, PV News, July 2007 Greentech Media and Prometheus Institute, 2008

7. 7 U.S. Non-Residential PV Installations California remains over half the U.S. market Power Purchase Agreements (PPA) growing quickly

8. 8 U.S. PV Industry Market Trends Utilities entering owner – operator space Policy uncertainties are becoming a barrier to sustained development Rapid expansion (or everyone’s got the “solar bug”) Emerging dominance of Power Purchase Agreements (PPAs) Utility-scale projects becoming commonplace – hundreds of MWs 0% 100%

9. 9 Power Purchase Agreement: Opening Markets for Solar Complicated financial incentives than Europe require PPA + third party ownership –Capital conservation: no up-front capital expenditure –Limited operational risk for customer – key differentiator from lease buyback model –System purchase options for the energy end-user

10. 10 The Power Purchase Agreement: A Long Marriage The PPA is a long term contract in which the customer buys the electricity from the system owner on a set price schedule SYSTEM OWNER RESPONSIBILITIESCUSTOMER RESPONSIBILITIES Buys System Electricity 10—25 year span Provides System Site (for retail systems) Site lease agreement Develop & Finance Permitting Design Procurement Installation Own & Operate Operations Maintenance Insurance

11. 11 PV Projects with Third Party Ownership: Competing Interests on the Path to Standardization  Use new technology  Commitments before $  Make customers happy  Sell high  Secure tax benefits  Minimize risk — Credits, Technology, Operations  Buy low INVESTOR DEVELOPER “Just this once and then we can replicate.” CUSTOMERS WANT TAILORED SOLUTIONS “Just keep it simple and cover all the bases”

12. 12 Differing Views: Return Expectations DEVELOPERINVESTOR “Lower risk than wind”“Where’s the money?”Return Expectations  IRR vs. money  Valuing the PPA Provider  Residual Value “If I deliver, you fund”“Sure…just make sure you deliver” Financing Risk  State regulatory timing issues  Who bridges delays?  Credit market meltdown “No moving parts, …..solar lasts forever” “Get me out in six”Operating Risk  Less than perfect installations  Taxes and changing incentives  Erosion and peeling on modules

13. 13 A Typical U.S. Solar Fund Syndication Diverse Financial Products –Aggregation of PV projects – diversification of risk –Leveraged structure with senior debt at the project level –Majority of returns come from federal tax benefits –Partnership structure – not a lease –Proven technology Exit for Investor –Clear exit path, terms, and overall deal Yields –Matching risk & return. Consider fund-level risk, leverage, and credit protection from each party

14. 14 Uncertainty in Federal Policy No long-term Federal policy is established. Delay in extending the 30% Solar Investment Tax Credit (ITC) undercuts installation. Industry believes another one year extension is likely, though timing is uncertain. Current ITC restrictions include: –Not available to utilities –Residential credit capped at $2000 –Not available to Alternative Minimum Tax (AMT) payers Several carbon emissions schemes are currently under debate in the Senate. Discussion of national Renewable Portfolio Standard too. The leading Presidential candidates all favor a federal cap-and-trade system for carbon emissions.

15. 15 Solar Investment Tax Credit Extension is held up due to lack of compromise between Senate Republicans and House Democrats over funding Fundamentally, ITC caught up in larger political issues and election Industry impact from delay –Temporary demand spike to qualify for 2008 driving up prices –Orphaned projects –Layoffs at project firms –Domestic firms (and jobs!) going offshore –Accelerate industry consolidation?

16. 16 The Solar Alliance An Alliance of –PV Manufacturers –Systems Integrators –Financiers Working at the state level to adopt cost-effective solar policies and programs

21. 21 The two biggest PV projects in U.S. are located in Nevada (Nellis) and Colorado. Both states have: –Good solar insulation – not nearly as good as New Mexico –Stable, long-term policy regimes – state Renewable Portfolio Standard with a solar carve-out – enabling long-term contracts with utilities Building similar projects in New Mexico will depend on: –Certainty on federal ITC extension through 2010-2011 –Motivated communities and stakeholders to help bring all the required pieces into place (expedited permitting, additional financial support, etc) Creating the Next Nellis

22. 22 Nellis Air Force Base – 14.2 MWs Ground mounted tracking system that covers 140 acres Using over 70,000 solar modules with tilted trackers Largest PV system in Americas Nellis Air Force Base

23. 23 MMA RV: Financed, Owned & Operated ~$100MM project on Nellis Air Force Base (AFB) property, eight miles northeast of Las Vegas, Nevada All electricity sold to U.S. Air Force under 20 year Power Purchase Agreement contract All Renewable Energy Certificates (RECs) sold to Nevada Power under contract under State Renewable Portfolio Standard w/solar carve out Saves Nellis ~$1 Million annually Nellis Air Force Base

24. 24  Total Third Party Construction Cost ~ $100 million Nellis Construction Funding Schedule * A typical solar project construction takes approx. 8 – 9 months. 12/21/07 – Final Completion Date and Perm Debt Funded

25. 25 Final Thoughts U.S. is the most promising solar market in the world today U.S. solar industry competing with European firms –Third party ownership facilitates entry of European firms –ITC risk pushing U.S. firms overseas But, U.S. solar industry still playing catch- up with Europe, due to weaker policy environment Project financier and third party capital necessary for U.S. market growth due to incentives structures

26. 26 Seeking a Level Playing Field for Solar Congress considering permitting utilities to receive ITC (currently not permitted) –Utilities starting to enter the North America PV generation market (SCE, Duke) Utilities can bring scale to industry But utilities are already receiving federal subsidies and regulatory advantages Incentives should encourage all market participants to make the solar marketplace
