In 2013, NRG filed notice that it planned to decommission the coal generators by 2017, citing state emissions requirements. In May 2015, NRG filed notice to delay deactivation until May 2019. In
February 2016, NRG withdrew its de-activation notice for the coal-fired units.

In May 2020, GenOn
Holdings announced it would retire the three coal generating units, citing unfavorable market conditions and increased costs associated with environmental compliance. The coal units were shut down later in 2020.
