Ivanpah solar plant wants to burn more natural gas

But since the sun doesn’t shine all the time, the plant uses natural gas to keep the water hot. And, apparently, there hasn’t been enough sun to do that. Bright Source Energy, the company operating the plant, is petitioning the California government, requesting permission to burn more natural gas

Compromise in Arizona defers a solar power fight

“The distributed rooftop solar industry has just been pushing for so long, ‘There’s no cost shift, there’s no cost shift, there’s no cost shift,’ and I think increasingly you’re seeing people both in California and Arizona and in other places say, ‘No, this is a real issue and we’ve got to deal with it,’ ” said Jeff Guldner, senior vice president for customers and regulation of Arizona Public Service. “If we don’t do something to address it you’re going to have the system collapse.”

Arizona utility tries storing solar energy for use in the dark

Solana is not the first renewable energy plant with storage; several have added banks of electric batteries. But battery storage is so expensive that these have been used mostly to smooth the output of the plant, not to store huge amounts overnight. Batteries are expensive and have a limited lifetime. They are more economical in a car, where they help electricity substitute for something more expensive, like gasoline. But for utilities, they are nowhere near cheap enough to justify using them to avoid buying high-priced, late-afternoon electricity.

Another Wind Project May Threaten Condors

According to the project's final EIS, the geographic limits of the Grand Canyon condor population as determined by FWS overlap the project's proposed footprint. Condor can fly up to 160 miles a day in searching for food, and the Grand Canyon "experimental" population is well within that range of the Mohave County Wind Farm.
