BUILDING A HYDROPOWER STATION
-
The system was designed by ANF Consulting and JNP of Brighouse.
-
It comprises twin Archimedes Screws manufactured by Spaans Babcock.
-
It has been delivered by Eric Wright Civil Engineering, on time and to budget, aided by Cobalt Project Management.
-
It is connected to the grid via a Northern Powergrid substation at the site.
-
Commissioned in September 2015 it:
-
delivers up to 260kW of capacity, generating around 1,000,000 units (kWh) per annum
-
enough electricity to take around 300 average UK homes off the grid almost in perpetuity
-
THE PROJECT
-
Barn Energy has consulted very closely since March 2013 with local angling groups, the Don Catchment River Trust, neighbours and landlords (the Environment Agency and the Canal & River Trust)
-
Environment Agency Abstraction Licences (for hydro and fish passage) and Rotherham Planning Permission were granted in September 2014 with not one expression of dissent made.
FISH AND EEL PASSAGE
-
Weirs have been effective and complete obstacles to upstream salmon/trout passage – and returning eel and elver populations;
-
This scheme sees the removal of that obstacle at Thrybergh weir, providing these species, plus adult coarse fish, the means to migrate upstream for the first time for centuries;
-
A so-called Larinier fish pass, together with an eel pass on the weir, and a revision of the defunct structure on the weir as a bywash, together with the new fish pass at Sprotbrough, provides connectivity on the Don, another step on the way to getting salmon to Sheffield.
