Preparation of the
2009 Integrated Energy Policy Report
(2009 IEPR)

Docket No. 09-IEP-1E



Notice of Staff Workshop on
Present and Future Central Station
Renewable Energy Facility Plant Costs

In support of the 2009 Integrated Energy Policy Report (2009 IEPR), the California Energy Commission (Energy Commission) staff will conduct a workshop to receive comments on draft results from a study on the present and future costs of electricity generation from central station renewable energy facilities and other generation sources. Commissioner Jeffrey D. Byron is the Presiding Member and Vice Chair James D. Boyd is the Associate Member of the 2009 IEPR Committee. While this is a staff workshop, Commissioners from the Energy Commission may attend and participate in this workshop. In addition, Commissioners and staff from the California Public Utilities Commission may attend and participate. The workshop will be held:

9 a.m.
1516 Ninth Street
First Floor, Hearing Room A
Sacramento, California
(Wheelchair Accessible)

Renewable energy (RE) deployment in California is expected to accelerate in the near term in response to legislation identifying supply portfolio targets and climate mitigation targets. Related policy development must be based on the best possible economic information, especially the cost of bulk RE electricity generation. To obtain this information, the Energy Commission has hired a consultant to examine these economic topics. This workshop will include a presentation by the Energy Commission's consultant on the draft results from the research. The workshop will be an opportunity for public comments on the draft results of the study.

In addition to the RE technologies, two non-renewable energy (NRE) technologies with potential for expanded use in California are being examined in support of the Cost of Generation modeling of the Energy Commission's Electricity Analysis Office and as comparisons to the RE technologies. The two NRE technologies included in this project are nuclear and integrated gasification combined-cycle technology (IGCC).1


To provide cost of generation information, four topics are being addressed in the project:

  • Identification of the commercially feasible RE technologies and of two NRE technologies likely to be deployed in California over the next 20 years, along with identification of the infrastructure scales at which they are likely to be deployed, for example, utility, community, and building.
  • Analysis of cost drivers and trends for each likely contributing technology and quantitative analysis of factors that determine the range of expected costs.
  • Modeling of current costs for recommended utility-scale RE technologies and two NRE technologies to find plausible minimum and maximum costs.
  • Analysis of expected cost trajectories over the 20-year time frame for utility-scale generation technologies, along with the result of applying this analysis to current costs.

Background information on these topics is available on the Energy Commission's website at

1 Integrated gasification combined cycle technology: Fuel, water, and oxygen are gasified to produce syngas, which is cleaned and fed to a gas turbine. The hot exhaust of the gas turbine and heat recovered from gasification are routed through a heat-recovery generator to produce steam, which drives a turbine to produce electricity.
