3. PART 1 - REC’s-Renewable Energy Certificates 1 REC =1 MWh of electricity production from a renewable resource In a REC, the renewable attributes are unbundled from commodity energy Projects can generate two revenue streams -one for commodity, one for REC’s -Has implications for financing The market is still illiquid, but emerging -A recent DOE report says the REC market is $145 MM/yr. -DOE Forecasts that it will get to $900 MM/yr. By 2010

4. The Markets in which REC’s Trade There is not one single unified U.S. market for REC’s - instead, there are a variety of fragmented State and regional markets - Prices from market to market may vary considerably Mandatory Compliance vs. Voluntary Markets - Some RPS States include mandates to purchasers of power - Purchaser must either purchase REC’s, purchase renewable power, generate renewable energy, or pay penalties - The price of a REC in theory should approach compliance penalties -Penalty ranges are $10-50/MWh varying by state and market - Thirteen states have or are phasing in REC trading as a feature of their State RPS - Voluntary markets also exist in which purchasers desire to encourage development of clean renewable energy sources through their purchases

5. RPS States As of 10/2005 From CRS

6. REC Prices-Voluntary Markets Higher Prices in MidAtlantic-Northeast than in Central and Western States Reasons: -Lower Wind Class resources in MidAtlantic-Northeast -Higher consumer demand for renewables with tight supply -Growing number of State RPS policies in the region. In general, REC prices are a function of individual markets, applicable law, supply, and demand

8. REC Ownership, Tracking, Certification, and Contracting Rules for earning REC’s, transfer, certification, and distribution vary from state to state and are state specific or regional in nature - Rules include tracking systems and expiration dates - Banking of REC’s –Usually allowed 2-3 years out - Certification systems such as Green-e can also apply REC Ownership -Per FERC, REC’s belong to generator unless conveyed in PPA or unless specified otherwise by the applicable State -Ultimately, State law governs who owns REC’s PPA Structuring -Change of law risk in PPA -Purchasers want firm REC’s with LD’s for non delivery other than for Force Majuere -Mitigate risks via portfolio of REC’s/projects, alternate back-up supply of REC’s, -Cap LD’s

9. Miscellaneous Financing and Structuring Considerations Carve out REC revenue from collateral in Security Agreements Royalty and Lease agreements-carve out REC’s from Revenue

10. Issues for REC’s In Project Financing Projects are financed over 10 to 20 years Due to the nature of the emerging market for REC’s, and regulatory uncertainty, the Term for REC contracts is usually no longer than 5 years, and usually 1-2 years Exceptions are States where as part of the State RPS, long term contracts are required: -New York 10 years -Colorado 20 years -California 10 years

11. Financing Issues and Solutions REC’s (Continued) For large projects -REC marketers are generally too small and have insufficient credit to provide the necessary security for guaranteeing or backstopping long term REC purchase agreements In some markets, large creditworthy end-users, such as universities or government agencies have committed to make long-term commitments (i.e., 10 years or more) to purchase stand-alone REC’s or REC’s bundled with energy. The same large entities may enter into a REC contract for differences would provide price stability to the buyer and revenue security to the seller

12. Financing Issues and Solutions REC’s (Continued) State renewable energy funds could offer a price floor for REC’s to ensure minimum REC revenue, as one component of a risk management strategy Example: -The Massachusetts Renewable Energy Trust offering to purchase—or purchase options to buy—REC’s for a period of up to 10 years These funds are limited, however, in the number of projects they can support States could require long-term contracts for bundled energy or stand-alone REC’s as a means of satisfying an RPS

13. Financing Issues and Solutions REC’s (Continued) Forward Selling of REC’s -REC’s that will be generated over the lifetime of a new or planned renewable energy project can be sold in advance to consumers before the project is constructed -The present value of the future revenue stream can be used to finance the project directly Example: Vermont-based NativeEnergy’s customers purchase REC’s that will be generated during the expected operating life of renewable energy projects.

14. Financing Issues and Solutions REC’s Continued With its Windbuilder’s product, NativeEnergy helped support the development of the 750-kW Rosebud Sioux wind turbine in South Dakota by selling the REC’s that will be generated during the 25-year expected life of the turbine. NativeEnergy discounts the REC’s price to account for the time value of money and the avoided risk of the project not being able to sell all of the future REC’s. Because NativeEnergy markets REC’s from prospective projects the company guarantees that it will support an alternate project or purchase REC’s from other new renewable facilities, in the event that the initial project is not completed.

15. Financing Issues and Solutions REC’s Continued Note this kind of forward sale has only been done on a small scale to date because of the challenge of forward selling the entire output of a large project. Although this product can help develop som e small renewable energy projects, it may be slow to generate financing for substantial expansions in large scale renewable projects. Perhaps large credit worthy state agencies, trusts, and other governmental authorities can also assist in achieving larger scale forward sales.

16. Example of DSCR Calculation - BASE CASE * For a 100 MW Project with 35% Capacity Factor

17. Example of DSCR Calculation With REC of $10/MWh * For a 100 MW Project with 35% Capacity Factor

18. Comparison of REC Enhancements To Base Case A REC price of $10/MWh or.01/KWh increases project revenue by $2.8 MM/yr. for a 100 MW project Available leverage or D/E ratio, holding DSCR constant goes up by 12% from D/E ratio of 63% to 75% Project IRR also goes up Alternatively, with an extra REC revenue stream, the project may choose to hold revenue and returns and D/E ratio constant and bid more competitively on the PPA pricing

19. It may eventually be possible to achieve higher D/E ratios if a REC revenue stream meets certain criteria -Lenders should consider issuing a separate tranche of debt with higher margins and DSCR’s, but allow REC’s to add some leverage over a term matching the length of the REC purchase contract -Lenders could allow funding of Debt service reserves with the REC revenue stream For REC’s to be accepted as a financeable revenue stream: -Lenders need a strong state and or regional legal and regulatory environment -REC purchasers and PPA counterparties must be creditworthy -Longer term REC contracts and purchases are needed, - More liquidity and bankable forward price curves need to develop For now, with state of markets, probably safer not to try to disaggregate attributes Financing Conclusions For REC’s

20. More “Due Diligence” is Always Better Make sure your deal is a REC deal not a Wreck deal

21. PART 2 - Depreciation Industry MACRS tax depreciation norm is 200% declining balance over 5 year depreciation life This is substantially shorter than the 15 to 20 year depreciation lives of non-renewable power supply investments Faster depreciation results in tax benefits early in a project's life because a dollar is worth more today than later on Depreciation Can be allocated disproportionately to ownership The Internal Revenue Code of 1986 (as amended) now provides for additional accelerated depreciation of property placed on tribal reservations

22. Eligibility for Accelerated Depreciation on Tribal Reservations To be eligible, the property must: Be used by the taxpayer predominantly in the active conduct of a trade or business within an Indian reservation on a regular basis Not be used or located outside the Indian reservation on a regular basis Not be used in conducting or housing class I, II or III gaming as defined in the Indian Regulatory Act Not be residential rental property Not be owned by a person who is required to use the "alternative depreciation system".

23. IRS 168(j) Depreciation Lives on Reservations Property Class Life Accelerated Depreciation Life 5 years 3 years 7 years 4 years 10 years 6 years 15 years 9 years 20 years 12 years 39 years * 22 years *(nonresidential real property)

24. Qualified Indian Reservation Property The term “qualified Indian reservation property” means: Property which is, used by the taxpayer predominantly in the active conduct of a trade or business within an Indian reservation, not used or located outside the Indian reservation on a regular basis, The above restriction shall not apply to qualified infrastructure property located outside of the Indian reservation if the purpose of such property is to connect with qualified infrastructure property located within the Indian reservation. not acquired (directly or indirectly) by the taxpayer from a person who is related to the taxpayer (within the meaning of section 456 (b)(3) (C ), and not property (or any portion thereof) placed in service for purposes of conducting or housing class I, II, or III gaming (as defined in section 4 of the Indian Regulatory Act (25 U.S.C. 2703)). The term “qualified Indian reservation property” does not include any property to which the alternative depreciation system applies

25. Qualified Infrastructure Property-Off Reservation “Qualified Infrastructure Property” means qualified Indian reservation property which : Benefits the tribal infrastructure, Is available to the general public, and Is placed in service in connection with the taxpayer’s active conduct of a trade or business within an Indian reservation. Such term includes, but is not limited to, roads, power lines, water systems, railroad spurs, and communications facilities.

26. CreatingValue in Allocation of Depreciation Can disproportionately allocate to an investor or partner who has the tax appetite to monetize the depreciation to offset their taxable income Upon audit, an investor must show there was economic justification for a disproportionate allocation of tax credits and be able to show “differentiated risks” The downside is to risk disallowance and unwinding of the structure entailing financial consequences to the investor and the project It may be best to get a letter opinion from the IRS

27. Creating Value in Using Accelerated Depreciation The benefit of accelerating depreciation is the present value of the stream of avoided cash taxes when added taxable income is offset in years 1-3 versus over a 5 year period The effect of combining disproportionate allocation and accelerated depreciation can make a substantial value creation difference and result in higher returns for investors and partners who can monetize these benefits
