Regulators Allow California Solar Plant to Operate Despite Annual Bird Deaths

Regulators are permitting the Ivanpah Solar Power Plant to continue operating despite documented bird deaths at the facility, a Fox News Digital investigation reported. The plant, located in the Mojave Desert near the California-Nevada border, uses concentrated solar beams reflected onto three central towers.

Monitoring reports show hundreds of birds found dead at the site each year, with some estimates reaching the thousands. The California Energy Commission told Fox News Digital that staff is not aware of any formal enforcement actions or fines issued by the U.S. Fish and Wildlife Service or the California Department of Fish and Wildlife related to avian or wildlife mortality at the Ivanpah Solar Electric Generating System.

The commission said it knows of no special regulatory exemptions for renewable energy projects related to wildlife impacts. The project was approved on the condition that monitoring and mitigation requirements would be carried out.

The Ivanpah facility was approved during a push to expand renewable energy following the 2008 financial crisis. The federal government provided a $539 million grant for its construction along with a separate $1.6 billion loan. At approval, regulators knew the project could kill birds through exposure to concentrated sunlight or collisions with mirrors and could affect the surrounding 4,000-acre desert habitat.

Environmental reviews raised concerns about damage to protected species including the endangered desert tortoise. Dozens of tortoises went unaccounted for during early operations. A 2016 congressional review found no clear evidence that federal agencies had pursued penalties for bird deaths at the site.

Researchers have documented birds drawn to the bright towers that then fly through the plant’s concentrated solar beams, known as solar flux. A video released by the U.S. Geological Survey shows a bird trailing smoke as its feathers burn. Songbirds, doves, warblers and other migratory species have been found dead at the plant.

The plant relies on natural gas to start up each day, producing tens of thousands of metric tons of carbon dioxide annually. Its technology has been overtaken by conventional solar panels that absorb sunlight directly. The facility remains in compliance with its environmental approvals, which anticipated some level of wildlife mortality.

Responsibility for enforcement is shared across the U.S.

Fish and Wildlife Service, the California Department of Fish and Wildlife and the Bureau of Land Management. The U.S. Fish and Wildlife Service said it reviews monitoring data and provides technical input but did not indicate enforcement action tied to bird deaths at the site.

NRG Energy, which operates the facility, said in a previous statement it remains committed to providing renewable electricity. Under federal law, violations involving protected migratory birds can carry fines of up to $15,000 per bird. In 2017, the Department of the Interior reinterpreted the Migratory Bird Treaty Act to apply only to intentional killings.

Federal courts have since reinforced that narrower reading, limiting the government's ability to penalize companies for incidental bird deaths caused by industrial activity. Efforts to reduce harm at Ivanpah, including deterrents, lighting changes and operational adjustments, have not eliminated the annual wildlife deaths documented in monitoring reports.
