Duke Energy Indiana said March 24 that it has requested the Indiana Utility Regulatory Commission (IURC) to modernize, replace and upgrade the three hydroelectric turbines, generators and related equipment which have been in service for nearly 50 years.
The Duke Energy (NYSE:DUK) subsidiary said Work on the project could begin around mid-2016 and conclude by mid-2020.
The Markland hydro project is located near Florence, along the Ohio River.
Duke outlined its plans to modernize the 65-MW Markland facility as part of its integrated resource plan that was filed with the IURC in November.
Originally entering service in 1967, key generating components at Markland Station are still utilizing original technology. Duke Energy Indiana proposes to overhaul and upgrade each Markland unit from the ground up, replacing most components with more modern, efficient options.
“The generating units at Markland Hydro have served our customers well with clean, renewable energy since 1967,” said Melody Birmingham-Byrd, president of Duke Energy Indiana. “As we move toward increasingly cleaner energy, these modernized generation units will harness more of the renewable resources of the Ohio River for many years to come.”
