LOS ANGELES (AP) — The Ivanpah Solar Electric Generating System, once touted as a groundbreaking achievement in clean energy, is slated for closure after just 11 years of operation. The plant, located on roughly 5 square miles of federal land near the California-Nevada border, will be shut down due to the rising cost-effectiveness of newer solar technologies.
Pacific Gas & Electric (PG&E) announced it has agreed with the plant’s owners, including NRG Energy Inc., to terminate its contracts, leading to the closure of two of the plant’s three units starting in 2026, pending regulatory approval. Southern California Edison is also in discussions to buy out its contract. The decision is driven by the lower costs associated with photovoltaic solar technology, such as rooftop panels, which have outpaced Ivanpah’s concentrated solar power (CSP) technology in efficiency and affordability.
NRG Energy stated that while the Ivanpah project was successful, it couldn’t compete with the advancements in photovoltaic technology and battery storage. The Ivanpah plant, using 350,000 mirrors to reflect sunlight onto towers, faced challenges from the outset, including lower-than-expected sunlight and consequently lower electricity production.
The plant’s closure comes amidst longstanding environmental concerns. Environmental groups have criticized Ivanpah for killing thousands of birds and desert tortoises due to its design. The Sierra Club called the project a “financial boondoggle and environmental disaster,” highlighting the habitat destruction and loss of rare plant species.
While the plant’s decommissioning is expected, the future of the site and its equipment remains uncertain. NRG suggests the possibility of repurposing the land for photovoltaic solar energy production. The closure highlights the rapid evolution of renewable energy technologies and the competitive landscape in the clean energy sector.
