A hydro turbine, wind turbine and solar panels are set to be placed in a fenland drain to trial new renewables technology.

The Environment Agency has been given planning permission to site the equipment near the Cut-Off Channel tail sluice at Denver, near Downham Market.

A planning statement says: "The generation of renewable energy onsite would deliver C02 savings associated with the operation of the Environment Agency premises, including electric vehicle charging, during the temporary period of operation of the development.

"The proposed development comprises of prototypes that are going through an evaluation.

"The technologies proposed are to be assessed for their performance before they are considered whether they are suitable and to be deployed on a wider scale."

The EA has been given permission to trial the equipment for 18 months, during which its impact on fish in the drain will also be assessed. The wind turbine will be 3m high.

The Cut-Off, which runs between Barton Mills and Denver, was built in the 1950s to carry excess water from the rivers Lark, Little Ouse and Wissey to the main Relief Channel at Denver.
