Expected to commence operations in second quarter of 2013, the powerhouse was recently re-watered following a five-year $111m upgrade.
Located on the Genesee River at the Lower Falls, a tunnel relining project had halted operations at the hydroelectric station.
The renovation works were jointly undertaken by RG&E and its parent company Iberdrola at the Station 5 powerhouse and the Middle Falls dam & head gates in 2007.
RG&E president Mark Lynch noted that the company, along with Iberdrola USA, is committed to investing in sustainable energy.
"That’s why we’re rebuilding this century-old station to provide our customers with green, renewable power for years to come," added Lynch.
The hydro plant is expected to begin power generation from an installed capacity of 46MW in December, producing sufficient renewable energy to annually power over 30,000 homes in Rochester.
