Middle Brook, MO

Modernizing Power.

PayneCrest earned AGC Keystone Award honors for modernizing a 45-year-old hydroelectric plant with intense safety requirements in an eight-month schedule. Working at the foot and summit of a 1,500-foot mountain, PayneCrest created a more efficient hydroelectric plant that supplies power for 250,000 homes during peak hours.

“The Taum Sauk hydroelectric plant is an extraordinary engineering feat – one that PayneCrest helped make successful despite innumerable challenges.” — Robert Ferguson, Ameren UE, Managing Supervisor Project Engineering
