The Ivanpah Solar Energy Generating System is awaiting final approval by the California Energy Commission (CEC). The CEC issued a Presiding Member's Proposed Decision granting initial approval, but pending a 30-day public comment period, the decision is not set in stone. You can still submit comments to the CEC regarding the Ivanpah site. Please see Chris Clark's Coyote Crossing for further information.
You can email comments to the CEC at email@example.com and include reference to "Docket No. 07-AFC-5." For more information, see the CEC's public announcement on this.
