June 2018

Crews are installing technology at Allen Steam Station to convert to managing bottom ash dry. This is one of several projects underway to take the ash basins out of service and prepare to safely close them. Night work will be needed from late June to late September to complete the work. We expect this work to cause little disruption to neighbors and are taking a number of steps to minimize impacts overnight. Neighbors may hear occasional construction noise and may see cranes that are involved in assembling the new equipment.

2017 - 2018 

Work is underway to prepare for safely closing ash basins. This includes designing and constructing new retention basins for water management; installing state-of-the-art wastewater treatment systems; and installing new equipment to manage all coal ash dry rather than sending it to ash basins. While the work itself will occur on plant property, neighbors may notice periodic equipment deliveries and an increase in construction activities.
