Power plant recommissioning will deliver affordable capacity
Associated’s recommissioning of its Unionville Power Plant, a 44-MW liquid fuel peaking facility in layup status since
2014, will add capacity and also enhance fuel diversity. The ability to run on liquid fuel is valuable for generating
electricity when natural gas is either expensive or undeliverable. The plant will be available starting in late 2023.
System speeds restoration of
major transmission line
In December 2021, tornadoes brought down
almost five miles of Associated’s West New
Madrid-to-Dell 500-kilovolt line in southeast
Missouri. Seventeen structures were destroyed
with 10 of those towers suffering foundation
damage. Six more towers sustained damage at
conductor attachment points. Working together
with M&A Electric Power Cooperative, one of
Associated’s six member-owners, the transmis-
sion structures and line went back in service
June 1, 2022 – 30 days ahead of schedule.
Construction included replacement of 17 towers,
45 linear miles of conductor and 10 miles of
steel static wire at a cost of $10 million. Disaster
declaration reimbursements of 90% from the
Federal Emergency Management Agency and
up to 10% from the state of Missouri will cover
much of the cost.
