Archimedes Screw planned as power solution

The Highland Council is planning to install a Hydro Electric Archimedes Screw at Whin Park Lade.

The 100KW turbine will control the water flow from the River Ness through to Whin Park and will be able to generate 672,529 KWh, which is equivalent to the power for 150 homes.

The renewable energy project is estimated to generate an income for the Council of around £90k to £120k at current prices.  The annual operating cost will be in the region of £15k.

The electricity could supply council buildings, and local venues including the Aquadome and the archive centre, generating further savings.

The installation will be 4.2m in diameter and allow a controlled water flow, as well as providing sufficient screen to protect various species of fish. The turbine is designed to have a low environmental impact.

Chair of the Council’s Places Committee, Councillor Allan Henderson said: “This modern, innovative project provides an excellent opportunity for the Council to generate income and renewable energy and make savings.

“The Archimedes Screw is a fascinating piece of engineering and technology which in itself should be a feature of significant interest and may hopefully inspire young scientists of tomorrow.”

Site of planned Archimedes Screw hydro scheme at Torvean

The Highland Council contracted AMECFW and senior specialist in Archimedean screw hydropower systems, Mannpower Consulting Ltd, to develop the project design.

It is anticipated the planning application for the installation of the Torvean Micro Hydro Scheme Archimedes Screw will be submitted in Winter 2017 and will include consultation with relevant statutory consultees.
