Purpose

The purpose of this Staff Workshop is 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 will focus 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 will also be discussed. The staff welcomes public comments/feedback on process and results.

The findings and recommendations will be presented by an industry team, which has worked in close collaboration with representatives from California utilities, regional transmission study groups, industry stakeholders and state agencies, involved in transmission planning.


Background

The Energy Commission's Intermittency Analysis Project (IAP) is focused on examining the statewide system impacts of higher levels of variable renewables on the California grid, and to recommend technical, operational and policy strategies for mitigating impacts based on world-wide experience.

The IAP group has been working with the California utilities (Pacific Gas and Electric, San Diego Gas & Electric, Los Angeles Department of Water and Power, Sacramento Municipal Utility District, Southern California Edison, and the Imperial Irrigation District), the California Public Utilities Commission, the California Independent System Operator, the Consortium for Electric Reliability Technology Solutions, the Center for Energy Efficiency and Renewable Technologies, the renewable industry, the California Wind Energy Collaborative and the Energy Commission's Transmission Planning and Siting offices to ensure coordination and review of results and findings from the IAP. Close coordination with the utilities will help ensure mitigation measures and impact studies are relevant to current system needs. Other technical advisors from industry such as the Utility Wind Integration Group and the National Renewable Energy Laboratory are also participating.

This study will provide quantified system and transmission impacts of variable or weather dependant renewable generation. Results will be useful to guide transmission management and investment decisions as well as prioritization of resource development needs.
