LIVERMORE (AP) — Hundreds of turbines on Altamont Pass will shut down at the massive wind farm amid pressure from environmental groups.

The groups have fought to shutter the aging turbines because they can kill protected golden eagles, raptors, hawks, owls and other bird species.

Altamont Winds on the Altamont Pass near Livermore as told federal regulators it will cease operations of 800 wind turbines, which supplies renewable energy to businesses and residents throughout the state. Altamont Winds told the U.S Fish and Wildlife Service in an email Oct. 23 that it is ceasing operations as of Sunday.

The three other energy firms on Altamont Pass will continue operating, and have committed to upgrading equipment to improve safety for birds, the newspaper reported.
