The goal of the workshop is to determine what analysis is needed to identify and evaluate the major hurdles for attaining higher levels of renewables in California. Energy Commission staff held three workshops on this topic in July that focused on (1) physical, operational, and market changes necessary for California's electric system to support a minimum of 33 percent renewables by 2020; (2) removal of major transmission barriers associated with higher levels of renewable penetration; and (3) identifying emerging technologies that can aid and increase the integration and use of renewable energy resources in the state.

The IEPR Committee has identified the topic of how the 2020 electricity system could be structured to accommodate higher levels of renewables as a high priority. To meet the goal of 33 percent renewables by 2020, the Committee believes California will have to fundamentally change the way it operates its grid to enable the state to reduce its use of carbon-based fuels while maintaining grid reliability and stability.

The analyses and evaluations identified in the 2008 IEPR Update will take place as part of the 2009 IEPR. While the focus is on 33 percent renewables by 2020, the IEPR Committee believes it should also be considering even higher renewable goals, perhaps as much as 50 percent by 2050, given the urgency to address climate change impacts by reducing the electricity sector's greenhouse gas emissions.

Attachment A to this notice provides a summary of the three staff workshops held on this topic and identifies potential areas of analysis. Given the complexity of this issue, the IEPR Committee is seeking public comments on which key variables should be the focus of the 2009 IEPR analyses. The Committee also seeks input on how best to incorporate results from other analyses currently underway at the California Public Utilities Commission, the California Independent System Operator, the Renewable Energy Transmission Initiative, and other venues into the 2009 IEPR analyses.


Public Resources Code Section 25300, et seq., directs the Energy Commission to develop the IEPR every two years, with updates in the intermediate years, and directs state government entities to carry out their energy-related duties and responsibilities using the information and analyses contained in the adopted IEPR reports.

California currently has a mandate to achieve 20 percent of retail electricity sales from renewable resources by 2010, and the Governor and the state's energy agencies have identified a further goal of 33 percent renewable by 2020. This higher goal is a key strategy for meeting the state's greenhouse gas emission reduction targets.

Under the IEPR Committee's direction, the Energy Commission staff held three workshops in July to begin the discussion on what changes will be needed to incorporate higher levels of renewable energy in the state's electricity mix with the goal of achieving 33 percent renewables by 2020.

The first workshop summarized findings from existing reports and sought input regarding additional studies related to issues such as contract delays; potential price impacts for electricity; operational and physical changes needed to integrate renewables while maintaining reliability; potential impacts on natural gas demand, supply, and price; and environmental concerns.

The second workshop focused on transmission issues and provided additional discussion of the impacts of 33 percent renewables on operation of the electricity system, as well as environmental concerns.

The third workshop focused on the state of technologies, research and development needs, and the availability of technologies to enable integration of high levels of renewable energy into the electricity system.

At these workshops, parties identified areas of concern and potential analyses on topics associated with increasing renewables in California. In Attachment A, Energy Commission staff have also identified areas where additional analysis may be needed.


The Committee will take comments both at the workshop and in writing. The Committee requests that written comments on workshop topics be submitted by 5 p.m. on Thursday, August 28, 2008.
