ESI Energy, a wholly owned subsidiary of NextEra Energy Resources, agreed to pay $29,623 per dead bald or golden eagle under a federal plea agreement reached in Cheyenne, Wyoming, after admitting to at least 150 eagle deaths across eight states since 2012. Prosecutors stated the company operated without required federal permits, gaining an unfair advantage over law-abiding competitors.
NextEra Energy Subsidiary Pleads Guilty to Migratory Bird Treaty Act Violations
Federal prosecutors in Cheyenne secured a historic criminal penalty against ESI Energy, a subsidiary of NextEra Energy Resources, for violating the Migratory Bird Treaty Act. According to court documents, the company entered a guilty plea to three counts tied to documented golden eagle deaths caused by blunt-force trauma from turbine blades at facilities in Wyoming and New Mexico. Prosecutors noted that the company never applied for the federal permits required to authorize unavoidable eagle deaths.
The plea agreement laid bare a decade-long compliance failure. According to the U.S. Department of Justice, ESI admitted that at least 150 bald and golden eagles died between 2012 and the time of the plea across 50 of its 154 wind facilities. Documented deaths spanned Wyoming, New Mexico, North Dakota, Michigan, Arizona, Illinois, Colorado, and California. Court records confirmed that 136 of those fatalities resulted directly from turbine blade strikes.
The Arithmetic of Compensatory Mitigation: Pricing Dead Eagles
The unit price of $29,623 per carcass stems from the compensatory-mitigation economics applied by the U.S. Fish and Wildlife Service. According to federal regulators, that exact figure represents the estimated cost of offsetting a single eagle’s death, primarily by retrofitting power poles to prevent electrocutions elsewhere. Golden eagle populations in the American West remain flat at best, facing pressures from lead poisoning, poaching, habitat loss, and turbine collisions, with illegal takes numbering in the thousands annually across all causes, according to federal researchers.
According to the sources, golden eagles face severe vulnerability, with an estimated 31,800 individuals remaining in the Western U.S. and roughly 2,200 dying annually from human causes. While common birds face high mortality from domestic cats—which studies estimate kill up to 2.4 billion birds annually—wind turbines present an acute hazard to raptors due to their height and operational footprint. ESI was specifically warned that its wind projects in central and southeastern Wyoming, as well as a repowered facility near Albuquerque, New Mexico, posed severe risks to local eagle populations.
Did you know? Under the court-supervised Eagle Management Plan, ESI Energy agreed to spend up to $27 million on prevention measures—including curtailing turbine operations when eagles are present—while still paying the $29,623 mitigation fee for any bird the measures fail to save.
Industry Backlash and the Competitive Edge of Non-Compliance
The Justice Department argued that ESI’s actions amounted to more than accidental wildlife loss. Prosecutors emphasized that companies applying for legal permits face operational delays, design constraints, and substantial financial costs. By bypassing the permit process entirely, ESI gained a commercial advantage over competitors that complied with federal wildlife safeguards.

NextEra Energy Resources pushed back against the prosecution. Rebecca Kujawa, president of the company, stated that bird collisions with turbines are unavoidable accidents that should not be criminalized. According to industry advocates, the strict-liability reach of the Migratory Bird Treaty Act unfairly turns everyday infrastructure operators into potential criminal defendants. Despite these objections, the company accepted a sentence requiring $1,861,600 in fines, $6,210,991 in restitution, five years of probation, and millions more in preventative mandates.
Frequently Asked Questions
What was the total financial penalty imposed on ESI Energy?
The court imposed a $1,861,600 fine, $6,210,991 in restitution, and required the company to spend up to $27 million on an Eagle Management Plan, alongside a $29,623 per-carcass fee for any future eagle deaths during its five-year probation.
How many eagle deaths were uncovered in the investigation?
Court documents show ESI Energy admitted to at least 150 bald and golden eagle deaths across 50 wind facilities in eight states since 2012, with 136 confirmed as turbine blade strikes.
Why did prosecutors bring criminal charges instead of handling the case civilly?
Prosecutors stated that ESI operated for over a decade without seeking required federal permits, despite explicit warnings from the U.S. Fish and Wildlife Service, thereby avoiding the compliance costs borne by law-abiding competitors.
