The upgrade is intended to modernise the facility with new turbine technology and extending its operational life by 40 years. The plant currently generates 170 GWh annually.

The refurbishment will replace all the main generation components and enhance the output without requiring additional water volumes. The existing civil infrastructure will be retained.

Main construction activities will begin in April 2025. Voith Hydro has been selected as the lead mechanical and electrical contractor for the refurbishment. Global Infrastructure has been awarded the contract for enabling works. AJT Engineering will design and install an automatic self-closing valve.

The project is scheduled for completion by 2028.
