Wind energy company kills 150 eagles in U.S., pleads guilty

A subsidiary of one of the largest U.S. providers of renewable energy pleaded guilty to criminal charges and was ordered to pay over US$8 million in fines and restitution after at least 150 eagles were killed at its wind farms in eight states, federal prosecutors said Wednesday.

NextEra Energy subsidiary ESI Energy was also sentenced to five years probation after being charged with three counts of violating the Migratory Bird Treaty Act during a court appearance in Cheyenne, Wyoming. The charges arose from the deaths of nine eagles at three wind farms in Wyoming and New Mexico.

In addition to those deaths, the company acknowledged the deaths of golden and bald eagles at 50 wind farms affiliated with ESI and NextEra since 2012, prosecutors said. Birds were killed in eight states: Wyoming, California, New Mexico, North Dakota, Colorado, Michigan, Arizona and Illinois.

NextEra, based in Juno Beach, Florida, bills itself as the world's largest utility company by market value. It has more than 100 wind farms in the U.S. and Canada and also generates natural gas, nuclear and solar power

Almost all of the eagles killed at the NextEra subsidiary's facilities were struck by the blades of wind turbines, prosecutors said. Some turbines killed multiple eagles and because the carcasses are not always found, officials said the number killed was likely higher than the 150 birds cited in court documents.
