Timescale : October 2024

Value : £7k

Summary :

Thrybergh HEP is a twin Archimedes screw hydro station generating up to 260KW of electrical

energy by utilising the fall of up to 13 m3 of water per second over the 3m drop of Thrybergh Weir.

It was commissioned in October 2015 and has operated almost continuously since then.

A failure within the bearing on one of the Archimedes screws resulted in fractures within the bearing plinth. With the Hydro station running at 50% capacity, these stress related defects required urgent repairs prior to the installation of a new bearing.

Refurbishment :   

The hostile environment of the hydro station provided a considerable challenge which required extensive flood water management.

The stress fractures were cleaned out and sealed using Sikadur crack injection materials.

JDF RS Limited installed MAPEI Carboplate E170 protruded carbon fibre plates bonded to the plinth to secure the plinth structure.
