Dashville Hydroelectric Project Units 1 and 2 Upgrades

Dashville Falls on the Wallkill River (September 2020)

Overview

Dashville Hydroelectric station is located on the Wallkill River in eastern Ulster County, New York. The facility was built in 1920 and has stood on the Wallkill River for over a century. Central Hudson is working to upgrade the facility’s aging infrastructure to continue providing clean and renewable energy to its customers.

Construction of the Dashville Dam (c. 1920)

Central Hudson is utilizing funding through President Biden’s Bipartisan Infrastructure Law (BIL) which invests in maintaining and enhancing existing hydroelectric facilities to ensure generators continue to provide clean electricity, while improving dam safety and reducing environmental impacts.

The project will involve the modernization of equipment and real time monitoring capabilities. Activities will include the engineering and supply of two new hydraulic turbine runners, rehabilitation and refurbishment of the rotor poles, replacement of the stator winding, and replacement of the stator core along with cleaning, testing, and coating of the frames. At the completion of the project, the electricity generation from the plant is expected to gain an efficiency level of up to 13.21%.
