One of the Navajo Generating Station's three 750-megawatt generators.

The final trainload of coal was delivered to the Navajo Generating Station in northern Arizona this week. It signals the closure of the Kayenta Mine that feeds it, and spells the beginning of the end of the plant itself.

The NGS is one of the largest sources of greenhouse gas emissions in the country, and its owners’ announcement that they would close the plant in 2017 sparked years of battles over its future.

For more on that, The Show got a hold of the Arizona Republic’s Ryan Randazzo.
