Understanding why America’s biggest solar thermal project is coming to an end

California's $2.2 billion Ivanpah Solar Power Facility is shutting down after just a decade due to shifting economic realities. While the concentrated solar power plant was built between 2010-2014, photovoltaic solar panel costs plummeted 80% and natural gas became cheaper, making Ivanpah's complex mirror-and-tower system economically unviable. The facility consistently underperformed energy targets, faced environmental controversies over bird deaths and desert habitat disruption, and relied more heavily on natural gas backup than intended, leading utilities to abandon contract renewals.
