NRG Energy, Inc. (NYSE:NRG), through its wholly owned subsidiary NRG Solar, today announced that the Ivanpah Solar Electric Generating System produced its first output of energy when the Unit 1 station was synced to the power grid for the first time. Achieving this critical “first sync” is a major milestone for the project.

Power generated from Ivanpah’s Unit 3 station is also sold under a PPA with PG&E, while Unit 2 is under a PPA with Southern California Edison. Proof-of-concept testing will also be conducted at Unit 2 and 3 in the coming months. “This is yet another major milestone that we have successfully achieved as Ivanpah approaches completion,” said David Ramm, Executive Chairman of BrightSource Energy, Inc. “Ivanpah is the showcase project for BrightSource’s power tower technology and technical expertise. Validation at this scale demonstrates the viability of our technology as BrightSource increases focus on international markets and applications for concentrating solar power.”
