NRG’s Massive California Solar Plant Finally Making Enough Power

The world’s biggest solar-thermal power plant is finally producing enough electricity.

The Ivanpah Solar Electric Generating System in Southern California initially failed to meet contractual obligations, and a yearlong forbearance deal with Pacific Gas & Electric Co. expired Feb.1. After fine-tuning the complex facility that uses 170,000 mirrors, output is up and it’s no longer at risk of defaulting on the deal, according to David Knox, a spokesman for operator and co-owner NRG Energy Inc.

“We are currently in compliance with the contract,” Knox said in an interview. “The generation has improved dramatically.”
