3. WHITE & CASE LLP Section 1- Introduction to Renewable Energy in NY Presentation to ABA

4. WHITE & CASE LLP In New York State, forms of energy classified as renewable are: 1. Introduction to Renewable Energy in NY  Solar  Wind  Biomass/biogas  Hydro, wave and tidal facilities

5. WHITE & CASE LLP Section 2: RPS, RECs and Tax Credits for NY Presentation to ABA

6. WHITE & CASE LLP 2.1 NYSDPS Renewable Portfolio Standards (RPS)  RPS for New York State include:  New York State Department of Public Service (NYSDPS) Order on September 24, 2004: 25% of energy consumed in NY should be produced from eligible renewable resources by 2013 (effective 01/01/06)  Current level is about 19.5% counting existing major hydro projects (Niagra Falls and St. Lawrence Projects) Renewable Portfolio Standards (RPS) are state-level, top-down policies that require a certain percentage of a utility’s overall or new generating capacity or energy sales to be derived from renewable resources.

7. WHITE & CASE LLP 2.2 Sources for Meeting Future Standards for Renewable Power RPS estimates: The need to achieve the 25% RPS goal is expected to be met by: MW * Includes 250 MW of wind in PJM. *

8. WHITE & CASE LLP 2.3 Wind Energy: A Key Source for Meeting NY’s RPS A key source for renewable power, wind energy technology is: The fastest-growing energy technology in the world A rapidly growing industry in the U.S. Expected to be responsible for a significant level of electricity generation in the near future The number of wind energy projects in NYS totaled 48 in early 2005.

9. WHITE & CASE LLP Commodity electricity Renewable Energy Unbundled environmental “green” attributes 2.4 RECs Are Key to Meeting RPS Policy Goals Renewable Energy Credit/Certificates (RECs): Designed to promote increased reliance on renewable energy resources, typically premised on promoting policy goals (e.g., improved air and water quality). 1 REC (tradable certificate) generally = environmental attributes of 1 MWh electricity from a renewable generation source NY’s Renewable Portfolio Standard (RPS) includes:  Initial REC awards made to 7 renewable facilities  820,000 MWh contracted for 2006  First-year payments estimated at roughly $18 million

10. WHITE & CASE LLP 2.5 Production Tax Credits (PTC) for Wind Energy The PTC provides a 1.9-cent per kilowatt-hour credit (adjusted periodically for inflation) during the first 10 years of operation for wind power facilities placed in service before 12/31/07. The PTC is important for financing wind projects.

11. WHITE & CASE LLP Section 3: Key Regulatory Proposals & Initiatives Presentation to ABA

12. WHITE & CASE LLP 3.1 NYISO & NYSERDA - Commissioned Joint Study Conclusions of Phase 2* of the two-part study:  Wind generation can be held accountable to similar standards as conventional generation in terms of meeting day-ahead forecasts.  Exception: Imbalance penalties should not be imposed on wind generation. Source: “Phase 2” refers to the system performance evaluation report, “The Effects of Integrating Wind Power on Transmission System Planning Reliability and Operations” (03/04/05). Prepared for: The New York State Energy Research And Development Authority Prepared by: GE Energy Energy Consulting

13. WHITE & CASE LLP 3.2 FERC Order 888 – Permitted Imbalance Charges Order 888 from the Federal Energy Regulatory Commission (FERC): Allows imbalance penalties to be applied to generators that operate outside of their schedule. As applied in NY, any overgeneration can be accepted without payment, and any undergeneration is priced at the greater of 150% of the spot price or $100/MWh. Source: Phase 2 report, “The Effects of Integrating Wind Power on Transmission System Planning Reliability and Operations” (03/04/05)

14. WHITE & CASE LLP 3.3 “Phase 2” Report Findings Regarding FERC Order 888 According to the conclusions of the Phase 2 report:* Any imbalance penalties for undergeneration would tend to encourage underbidding the day-ahead forecast to the detriment of the entire system. Market for wind generation should be structured to:  Reward the accuracy of wind-generation forecasts.  Encourage wind generators to curtail production during periods of light load and excessive generation.  Provide clear financial incentive to reduce output when energy spot prices are very low (or negative). * Source: Phase 2 report, “The Effects of Integrating Wind Power on Transmission System Planning Reliability and Operations”

15. WHITE & CASE LLP 3.4 FERC NOPR on Imbalance Provisions for Intermittent Resources FERC Notice of Proposed Rulemaking (NOPR) on Imbalance Provisions for Intermittent Resources:  On April 14, 2005 (Docket No. RM05-10), FERC recognized the need to update Order 888 imbalance provisions as they relate to intermittent resources, such as wind resources. The NOPR proposed the following:  + / - 1.5 % hourly deviation band (2 MW minimum)  Deviations within + / -1.5% bandwidth, generator/transmission customer shall either:  Return-in-kind within 30 days, or  Pay 100% of incremental/decremental costs for underdeliveries/overdeliveries.  Deviations outside the + / -1.5% bandwidth:  Generator/transmission customer to pay the greater of $100/MWh or 110% of the system incremental costs for underdeliveries.  Transmission provider to pay 90% of its system decremental costs for overdeliveries. FERC has yet to issue a final rule.

16. WHITE & CASE LLP 3.5 Interconnection for Wind Energy (FERC Orders) Federal Energy Regulatory Commission (FERC) Order No. 661 issued June 2, 2005:  Requires transmission providers to append new provisions to their standard agreement and procedures for interconnecting large generating facilities, which are required under their open-access transmission tariffs (OATT), in order to address technical requirements and procedures for integrating large (>20 MW) wind power facilities into their transmission systems. FERC Order No. 2006 issued May 12, 2005:  Requires transmission providers to amend their Order No. 888 OATTs to offer non-discriminatory, standardized interconnection service for small generators (<20 MWs). The amendments involve inclusion of Small Generator Interconnection Procedures and a Small Generator Interconnection Agreement."

17. WHITE & CASE LLP 3.6 NYISO Proposals The New York Independent System Operator (NYISO) is developing straw proposals addressing numerous market-related issues:  Centralized wind-forecasting system  Interim market rules clarification of 500 MW limit  End-state market rules

18. WHITE & CASE LLP 3.7 Initiatives of WPNY Legislative goals of Wind Power of New York (WPNY):  Increase public funding for renewable energy projects.  Expand NY’s existing net metering and tax credits to include wind.  Enact legislation requiring that a percentage of electric power purchased for state agencies, universities and buildings come from renewable technologies, like wind.

19. WHITE & CASE LLP Section 4: Potomac Economics’ Analysis of RPS Market Impacts & Rate Structures Presentation to ABA

20. WHITE & CASE LLP 4.1 Methodology Potomac Report issued in June 2005 focused on two economic issues:  Effects of RPS on energy and capacity markets over the short run (2008) and long run (2013).  Impact of alternative procurement methods [renewable energy credit (REC) payment structures] – fixed versus variable RECs.

21. WHITE & CASE LLP 4.2 RPS Effects in New York Short-Run RPS Effects in New York:  RPS causes energy prices to decrease.  Capacity prices (UCAP market) in NYCA decrease by 16%.  In the short-run, load payments decrease significantly. Long-Run RPS Effects on Energy and UCAP Prices:  Energy prices decrease by 3.5% (in NYC) to 6.1 % (in the West); decrease varies per location.  Capacity prices increase by 14.5% in the rest-of-the-state area.

22. WHITE & CASE LLP 4.3 Qualitative Evaluation of Alternative Procurement Methods Qualitative Evaluation of Alternative Procurement Methods: Findings in the Potomac Report Favor Fixed RECs:  Fixed REC structure (resource earns constant $/MWh REC):  Provides more efficient investment incentives.  Includes incentives that reflect both installed cost and value of energy and capacity.  Provides more efficient dispatch incentive in the short-run.  Variable REC structure (REC payment varies such that the REC + energy revenue figure is constant):  LBMP has no effect on supplier’s revenues.  Favors investment at low installed-cost locations.  Allocates future market risk to load.

23. WHITE & CASE LLP Section 5: Financing Environment for Wind-Turbine Projects Presentation to ABA

24. WHITE & CASE LLP 5. Financing Environment for Wind-Turbine Projects The financing environment for wind-turbine projects has improved over recent years, although new challenges are prevalent: Pros:  Many projects have proven to be good investments, which has resulted in capital infusions into projects.  Availability of power-purchase agreements has improved.  The technology offers benefits over other sources of energy, including reduction in carbon intensity, economic growth potential to NY municipalities, declining costs as an energy source, while fossil fuel costs are high. Challenges:  Turbine supply is tight as developers act to lock in supply (favoring larger developers).  Turbine suppliers are requiring that deposits be paid to secure turbine contracts.  Some investors are unwilling to take the risk to invest in new plants with the uncertainty created by the short-term extensions of the federal wind energy production tax credit eligibility period.

25. WHITE & CASE LLP Section 6: PPA Contract Issues & Considerations Presentation to ABA

26. WHITE & CASE LLP Power Purchase Agreements (PPAs) Issues to keep in mind:  PPA is the primary source of revenues for the project.  Some power purchasers have standard contracts that are not well tailored for renewables.  A creditworthy power purchase is important for structuring financing of the projects.  Evaluate quantity. The PPA must be clear as to what is being sold.  Energy payment terms for PPAs may include:  Tariffs  Inclusion of environmental credits  Adjustments for:  PTCs (if the latter are not available)  Capacity factor or output (penalties)  Changes in law/capital expenses  Force Majeure  Damages for failure to perform can include delay liquidated damages & penalties for failure to deliver/accept delivery.  Transmission and scheduling: Historic approach left buyer with transmission risks. The trend is to push transmission-related risks and costs on to the seller. 6. PPA Contract Issues & Considerations
