1. State Policy Initiatives Financing Wind Power: The Future of Energy May 7-9, 2008 Richard Cogen

2. State Initiatives Renewable Portfolio Standards (RPS) Transmission Incentives

3. RPSs RPS is a policy which either requires or encourages that utilities supply a stated percentage of their power from renewable resources

4. RPSs Percentage goals vary from 2% to 40% with varying target years Many are mandatory; some are just aspirational

5. RPSs/Renewable Energy Credits RPSs stimulate the development of markets for RECs A REC is a credit equal to a unit of production of renewable energy (e.g., a MWh) RECS may be used to satisfy RPS requirements, instead of actual generation

6. RPSs/Renewable Energy Credits - 2 RECs have economic value that can approach the avoided cost of generation Prices for RECS vary geographically, and there is not yet an active market in many areas - in some places, e.g., MA and CT, can be in the $40 – 50/MWh range - in others, e.g., ME, economic value is much lower – under $1/MWh REC sales can provide a revenue stream to support wind energy projects

8. 2007 – 2008 RPS Activity 5 New State RPSs in 2007 -8 - Ohio - Illinois - New Hampshire - North Carolina - Oregon

9. 2007- 2008 RPS Activity 11 States made major revisions to their RPSs –California –Colorado –Connecticut –Delaware –Maine –Maryland –Minnesota –New Jersey –New Mexico –Pennsylvania –Texas

10. RPSs - 2008 Now, there are 26 States with RPSs, plus the District of Columbia The RPSs cover approximately half of the electric load in the country

11. Aggregate Targets Existing RPS goals are estimated to require: 32 GW of new renewable power by 2015 60 GW of new renewable power by 2025

13. State Transmission Incentives There is a growing recognition that, in many areas of the country, electric transmission infrastructure is not adequate to enable RPS goals to be met To address this problem, some states have adopted initiatives to facilitate construction of new transmission projects needed to serve wind rich regions

14. State Transmission Activities Texas: PUC preliminarily designated 5 Competitive Renewable Energy Zones (CREZ) to stimulate development of over 22 GW of wind energy. Once the process is completed, utilities will have one year to file applications to build transmission to serve the CREZs, and the PUC will be required to review those applications expeditiously

15. State Transmission Activities Colorado: 2007 legislation requires utilities to submit reports every 2 years designating Energy Resource Zones (ERZ), and identifying plans for serving those zones with transmission. Utilities must submit applications for approval of transmission facilities to serve the ERZs. Utilities are eligible for rate adjustment for the costs of planning, developing, and constructing the facilities

16. State Transmission Activities California: California ISO adopted new rate category for location constrained resources allowing for initial rate recovery through overall ISO tariff charge, followed by pro-rata sharing of costs by renewable resources using the line once they enter operation. State law also allows utilities to recover costs of lines needed to serve renewable energy facilities needed for RPS compliance for which full rate recovery would not otherwise be available

17. State Transmission Activities Minnesota: requires that utilities submit 5-year plans identifying transmission resources needed to meet RPS goals
