Red Rock Hydroelectric Project – New hydro development at an existing flood control dam

نویسندگان

چکیده

The Red Rock Hydroelectric Project converted the existing Dam near Pella, Iowa, from a non-powered dam into multi-purpose dam. flood control was constructed by U.S. Army Corps of Engineers (USACE) in 1960s on Des Moines River Iowa. hydroelectric project developed Western Minnesota Municipal Power Agency and generates up to 55 MW with an average annual energy output 178 gigawatt-hours. new intake, penstock powerhouse are located immediately adjacent spillway. Construction required large excavations upstream downstream sides embankment two penetrations through gravity monoliths. Extensive water earth-retention systems, prescriptive construction staging, robust safety surveillance program were designed maintain monitor integrity throughout avoid impacts active USACE operations. completed 2020. This paper provides overview unique challenges involved design at
