Executive Summary

Wind energy capacity and production have grown gradually in the past few years. This capacity and production increase comes from new developments and re-powering of existing turbines. The actual number of turbines in California has increased by 595, or 5.1 percent, from 2001 to 2003. The total installed capacity in California as of 2003 is 2,122 megawatts, MW. This is comprised of 191 MW of installed municipal capacity, 1,824 MW of reported capacity by investor-owned utilities, and an estimated 107 MW of unreported capacity. The 1,824 MW of reported, installed capacity represents about 5 percent of the world's total wind generating capacity of 39,294 MW in 2003.

The purpose of this report is to summarize the performance of wind energy projects in California in 2002 and 2003. Information on the number of turbines, nameplate capacity, energy production, and location is provided in tables and maps. This information is compiled from reports furnished by California's wind project operations.

This document reports wind energy capacity and production in California by turbine size, location, and year to the wind energy industry in California and beyond.

As a result of this report, the renewable energy community will have more accurate information regarding California's wind energy production. In 2003, the California wind industry reported 3,714 million kilowatt hours, kWh of electricity output. This is electricity sufficient to power approximately 539,511 households for a year.

While this report is not intended to offer conclusions, it can be noted that:

  • The uncertainty associated with renewal of the federal Production Tax Credit inserts ambiguity into wind turbine investment decisions.

  • The Renewable Portfolio Standards goal is the driving force in encouraging renewable energy development, such as wind.

  • Larger, more efficient turbines are gradually replacing older, smaller, lower capacity turbines, offering a increase in electricity generation from wind.

  • The capacity factor of California's wind energy turbine fleet is remaining steady in the 24 percent to 26 percent range.



Abstract

This document is prepared pursuant to Wind Project Performance Reporting System regulations (California Administrative Code, Title 20, Chapter 2, Subchapter 3, Article 4) and to support California Energy Commission (Energy Commission) staff analyses.

The purpose of this report is to summarize the performance of wind energy projects in California in 2002 and 2003. Information on the number of turbines, nameplate capacity, energy production and location is provided in tables and maps. This information is compiled from reports furnished by California's wind project operators. This report shows recent trends and presents some historical information regarding wind energy generation in California.
