The bill, which was introduced by state senator Joe Simitian, has been in the pipeline for the last four years. An earlier version of the bill was vetoed by former governor Arnold Schwarzenegger
The bill is now expected to be signed off by governor Jerry Brown.
Simitian said: "The legislation sends a signal to renewable energy providers that California wants them here. They will respond, as they have in the past, with billions of dollars in investments that will provide jobs and tax revenues."
According to the latest Windicator, California has a wind capacity of 2,814MW.
