In 2015, the Forestry Commission Scotland invited bids from developers to develop wind and hydro projects on their estate. This formed part of their wider drive to support the Scottish Government’s target to generate 100% of Scotland’s gross annual electricity consumption from renewable sources by 2020. Forestry Commission Scotland has a target to install 1.2 GW of renewable energy by 2020: http://scotland.forestry.gov.uk/managing/work-on-scotlands-national-forest-estate/renewable-energy
As part of this, in 2015 Renewables First was hired by a renewable energy developer to undertake a series of hydropower feasibility assessments on Forestry Commission Scotland Estate. This included a site on the Allt na Fearna in the Auchteraw Forest near Fort Augustus.
Once it was clear that the site possessed the necessary ingredients for a good hydropower site, Renewables First then completed design, consenting and planning works with a view to progressing the project. Osprey Energy have a lease in place to install and operate the Hydro scheme at the Allt na Fearna site.
With all consents and planning permission granted, the civil engineering works at the site will soon commence and be undertaken by a contractor, Peter Bluett. Following this, Renewables First will then project manage the mechanical and electrical engineering aspects of the project, principally the installation and commissioning of the hydro turbine.
Once the hydropower scheme is up and running, around 115 litres/second of water will be delivered to a turbine via a 780 metre-long penstock, descending a gross head of 143 vertical metres. The installed turbine will be a 100 kW Turgo turbine supplied by Hydrolite. The estimated annual generation of the turbine will be 412,000 kWh. This is equivalent to powering 107 Scottish homes and will displace 144,842 Kg of CO2/year.
With respect to the installation of the scheme, it is anticipated that tree felling works will begin in June 2017. Civil construction works will then follow, beginning in July and completed at some point during October. The hydropower turbine delivery, installation and commissioning will commence in November 2017.
Are you considering a hydropower project ?
The first step to develop any hydropower site is to conduct a full feasibility study.
