The purpose of this Staff Workshop was to present the IAP findings and preliminary results for the 2006 renewable baseline and the 20 percent renewables by 2010 Renewables Portfolio Standard, RPS, scenarios. As the first of two project workshops, this meeting focused on:

• Renewable portfolio scenarios (2010 - 20 percent renewables and 2020 - 33 percent renewables),


• Resource locations and penetration levels,


• Transmission upgrades, new development plans and assumptions, and


• Hourly and sub-hourly system reliability, dispatchability and operational impacts under the developed 2010 - 20 percent renewables scenario.

The renewable portfolio accounts for energy production from all renewable sources throughout the state and has been developed in conjunction with California utilities and various transmission study groups. Transmission simulations, production estimates, impacts on the transmission system, system reliability, dispatchability and potential system cost impacts (i.e., value of forecasting) due to increasing 2010 and 2020 penetration was also discussed.
