SAN BERNARDINO, Calif. – Regulators are allowing an Obama-era "clean energy" solar plant to continue operating even as its reflected solar beams kill thousands of birds each year, with no fines or enforcement action taken since it opened, a Fox News Digital investigation has found.

The Ivanpah Solar Power Plant, a sprawling facility built with taxpayer support in the Mojave Desert near the California–Nevada border, remains in compliance under existing regulations, even as birds are burned, injured or killed after flying through the beams which reflect sunlight onto the plant's three central towers.

Regulators were aware of those risks before approving the project as part of a broader push to expand renewable energy. Today, it remains in compliance, meaning the wildlife deaths documented at the site fall within limits set under its environmental approvals. That framework allows the plant to continue operating even as thousands of birds are killed each year.

OBAMA-ERA 'CLEAN ENERGY' SOLAR POWER PLANT STILL USES FOSSIL FUELS – AND KILLS THOUSANDS OF BIRDS ANNUALLY

"Staff is not aware of any formal enforcement actions or fines issued by either 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 California Energy Commission, which oversees large energy projects in the state, told Fox News Digital.

The commission also said it knows of no special regulatory exemptions for renewable energy projects related to wildlife impacts. Instead, the project was approved as long as monitoring and mitigation requirements would be carried out, meaning some level of wildlife mortality was anticipated.

The futuristic-looking facility, known for its three large towers that glow brightly when powered on, was approved during the Obama-era push to rapidly expand renewable energy following the 2008 financial crisis — part of a broader effort to cut emissions and reduce reliance on fossil fuels in the name of climate change.

At the time, it was hailed as the future of "clean energy" technology, and the federal government provided a $539 million grant for its construction, along with a separate $1.6 billion loan.

But its technology quickly became outdated by conventional solar panels that absorb sunlight directly and convert it into electricity, making Ivanpah's energy more expensive to produce. The plant also relies on natural gas to start up each day – producing tens of thousands of metric tons of carbon dioxide annually.

Researchers say birds are drawn to the bright towers, then fly through the plant’s concentrated solar beams — known as solar flux — where they can be injured or killed. Researchers dubbed the phenomenon "streamers," and 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.

Environmental reviews examined by Fox News Digital show that regulators were aware before construction that the project could kill birds, either by being burned by the plant’s concentrated sunlight or colliding with the tens of thousands of mirrors that surround the three towers like lakes. They also raised concerns about damage to the 4,000-acre physical desert habitat it was going to occupy, as well as to protected species that roam the barren terrain, such as the endangered desert tortoise, dozens of which went unaccounted for during early operations.

The project’s Final Environmental Impact Statement warned that climate efforts could come "at the expense of reducing the native biodiversity."

Even with those warnings, regulators approved the project, allowing it to move forward on the basis that ongoing monitoring and mitigation requirements would be carried out, rather than requiring those risks to be resolved.

A 2016 congressional review raised similar concerns, finding no clear evidence that federal agencies had pursued penalties for bird deaths at Ivanpah — a pattern that appears to have continued.

The plant is regulated under a system that tracks wildlife deaths but does not automatically trigger fines or shutdowns.

Monitoring reports show hundreds of birds are found dead at the site each year, with some estimates putting the total in the thousands.

Responsibility for enforcement is shared across multiple agencies, including the U.S. Fish and Wildlife Service, the California Department of Fish and Wildlife and the Bureau of Land Management, each of which has authority over different aspects of the project, the CEC said.

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 but declined to provide additional comment regarding environmental issues.

Instead of being treated like a typical environmental violation, the project is governed through a permitting system that emphasizes monitoring and mitigation rather than penalties.

In practice, that means harm can be documented without triggering enforcement action even though federal authorities have pursued penalties for bird deaths in other industries.

Under federal law, violations involving protected migratory birds can carry fines of up to $15,000 per bird.

Such prosecutions of industry have become rare in the United States, however. In 2017, the Department of the Interior reinterpreted the Migratory Bird Treaty Act to apply only to intentional killings — not "incidental" deaths caused by industrial activity such as oil pits, power lines or wind turbines. Federal courts, including the Fifth Circuit, have since reinforced that narrower reading, limiting the government's ability to penalize companies for equipment-related bird deaths.

But even efforts to reduce harm — including deterrents, lighting changes and operational adjustments — have not eliminated the problem at Ivanpah, with monitoring reports continuing to document annual wildlife deaths.

More than a decade later, Ivanpah shows what that system looks like in practice: a project approved as clean energy that kills wildlife, relies on fossil fuels and continues operating without penalties.
