This study shows the premature closure of the 2,250 Megawatt Navajo Generating Station, a coal fired power-plant, could destabilize the grid in the Southwest.

This study shows the premature closure of the 2,250 Megawatt Navajo Generating Station, a coal fired power-plant, could destabilize the grid in the Southwest.

According to the study, shuttering the Navajo power plant near Page, Arizona., in 2019 as its four utility owners voted to do earlier in 2017, would result in power deficiencies which could evolve into potential voltage collapse and outages, load shedding triggers, potential rotating brownouts, failing transformers or transmission lines and equipment damage, causing severe electric power disruptions in Phoenix, Flagstaff and other large Arizona cities, but also in California cities of Lugo and Shandon.
