Integration of Renewable Resources: Transmission and Operating Issues and Recommendations for Integrating Renewable Resources on the California Independent Service Operator (ISO)-Controlled Grid

This report addresses the transmission and operational impacts of interconnecting a major increase in the amount of renewable resources to the power grid. The report analyses the issues, documents the results and recommends steps that should be implemented to reliably integrate the planned intermittent resources. The report builds on other integration studies, particularly the California Energy Commission's (CEC's) Intermittency Analysis Project Final Report (July 2007)
