Notice of Staff Workshop
California Renewables Portfolio Standard
Renewable Generation Integration Cost Analysis:
Multi-Year Analysis Results and Recommendations


The California Energy Commission staff will conduct a workshop to present the multi-year analysis results and recommendations for integrating the cost of renewable energy generation. The workshop will be held:

MONDAY, APRIL 3, 2006
9 a.m. to 12:30 p.m.
CALIFORNIA ENERGY COMMISSION
1516 Ninth Street
First Floor, Hearing Room B
PLEASE NOTE ROOM CHANGE
Sacramento, California

(Wheelchair Accessible)


Purpose

The purpose of the workshop is to present the findings and recommendations on the following report: California Renewables Portfolio Standard Renewable Generation Integration Cost Analysis: Multi-Year Analysis Results and Recommendations (publication no. CEC-500-2006-024).

The report documents the results of the multi-year analysis effort covering the period from 2002 to 2004. The multi-year analysis provided opportunities to verify the consistency of the methodologies, further examine the practical issues associated with integration cost analysis, and compare the impact of renewables on integration costs over several years.

Previous reports from Phase I to III may be found online at: www.energy.ca.gov/portfolio/documents/index.html


Background

To support CaliforniaŐs Renewables Portfolio Standard (RPS), the Energy Commission initiated a multi-phase study to define and quantify the costs associated with integrating renewable generation into the stateŐs electricity system. The multi-year analysis effort represents the fourth and final phase of this effort. Under the first study phase, integration costs for renewables and non-renewable generators were reviewed and evaluated using a transparent and independent methodology. The second phase study focused on evaluating the impacts of changes in renewable generation technology, geography, climate, and level of grid penetration on the costs of integrating wind and geothermal resources. The third phase study focuses on a standardized methodology for calculating integration costs as part of the California Public Utilities Commission (CPUC) bid selection process. A one year dataset was analyzed and presented along with recommendations for implementing the standardized methodology. To address consistency concerns raised at the end of the one year analysis, it was decided that the RPS Integration Methods Group perform a fourth phase to apply the methodology using a dataset that spans multiple years.
