RIVERTON - The Empire District Electric Company announced that early the morning of Saturday, June 17, a controlled implosion was conducted as a part of the demolition project underway at its Riverton Power Plant. Significant preparation has taken place in the months leading up to the implosion to ensure the safety of the workers on site and the surrounding community.
The implosion brought down the exhaust stack and number 7 boiler unit. Additional charges were deployed to complete demolition of number 8 boiler unit.
The demolition project includes Riverton generating Units 7, 8 and 9. Unit 7 (38 MWs) and Unit 8 (54MWs) were coal-fired generators installed in 1950 and 1954, respectively. Unit 9 (12 MWs) was added in 1964 and operated on gas or fuel oil. Unit 9 used the exhaust heat from Units 7 and 8 for startup.
A portion of the attached controls building will remain as part of the substation and the old plant areas will be paved drives and grass. About 3,500 tons of material will be removed from the site and recycled or repurposed.
The production capacity of the retired units has been replaced by the more fuel-efficient Riverton 12 combined cycle unit, completed in May 2016. Due to the age and size of the units, it was not cost effective to make equipment upgrades necessary to comply with new Environmental Protection Agency regulations.
According to Blake Mertens, Vice President of Operations – Electric, “The Riverton Power Plant site has undergone many transformations since its origin as a hydro-electric facility in 1905. This latest transformation will remove aging structures and equipment, eliminate the associated maintenance costs, and improve the site appearance along the historic Route 66 corridor.”
