New plant equipment reduces emissions

The installation of major environmental controls, which cost nearly $550 million, at two power plants means reduced emissions and improved air quality.

Retrofit jobs at Coronado Generating Station in St. Johns and Navajo Generating Station near Page significantly reduce nitrous oxide emissions. New systems are being added at CGS to further reduce nitrous oxide, mercury and sulfur dioxide emissions. The coal-fired generating stations together supply about 3,000 megawatts of energy day and night. That's enough to power 600,000 homes.
