The hydroelectric project is owned by US-based power generation firm PPL Generation.
As part of the expansion, the company has installed advanced Kaplan turbines at the plant which are expected to improve the downstream fish passage.
The Holtwood hydroelectric plant is expected to generate clean electricity that is enough to power around 100,000 households.
PPL Fossil & Hydro Generation senior vice president Victor Lopiano said that this project, one of the largest expansions of its kind in the US, represents a major investment in clean, reliable, renewable energy.
"This project highlights the potential to upgrade existing hydroelectric facilities and expand capacity without the need to build new dams," added Lopiano.
