September was an extremely busy month for babyHydro, with the commissioning of two projects for developer vento ludens. Ledard Farm (100 kW) and Kelburn Estate (100 kW) were both built by MAM Contracting, with Turgo turbines supplied and installed by Hydrover Turbine Services. Civils works at Kelburn and Ledard will be completed within the next month. BabyHydro took Kelburn from initial site survey to project management of construction, and Managed Ledard through the delicate process of construction in Loch Lomond and the Trossachs National Park.
Carnoch Estate near Strontian is the proud owner of two new hydro schemes in neighbouring valleys, known as Black Corrie (262 kW) and Green Corrie (100 kW). Corrigan Contractors worked in steep-sided gorges to lay tracks and pipework, supplying two Gilkes Pelton turbines, in powerhouses visible from the Strontian road. BabyHydro project managed the construction of schemes that we first assessed in March 2013
BabyHydro has completed an assessment of 21 sites within Fife, Angus, Perth & Kinross, and Aberdeenshire, as part of the Historic Hydro project. Commissioned by EcoTechnic, the project focused on sites that had some form of existing hydro infrastructure. Thirteen sites were visited, and a pre-feasibility study was carried out for each. Three sites have been selected for further investigation, so project outlines have been supplied to the relevant planning departments.
This month babyHydro supported Suez Industrial Water Ltd in making the planning application for an upgrade to the effluent treatment plant at Aberfeldy Distillery. While not our core discipline, babyHydro were delighted to apply our planning and design expertise to a related field!
In 2016 Forest Enterprise Scotland (FES) set out to establish the full cost of decommissioning and restoring a hydro project, in the event that an asset is transferred back to them. FES appointed babyHydro Ltd to carry out an assessment of the cost to decommission and restore four existing hydro schemes on Forestry Commission Scotland land. As well as the assessment, this month BabyHydro delivered a ‘ready reckoner’ to allow easy calculation of similar costs for other sites, given a few basic site-specific parameters.
This month saw the commissioning of Milton of Callander hydro scheme for Moray Estates Development Company. Gilkes completed installation and commissioning of a 381 kW Pelton turbine, with civils works by TSL Contractors to be completed shortly. The project is in a National Park, so babyHydro completed a full Environmental Impact Assessment. BabyHydro carried out the pre-feasibility study for the project way back in 2013.
babyHydro has been awarded a contract by Glasgow City Council to bring the hydropower capability of the Pollock Sawmill back to life. The sawmill sits on the White Cart and lies within Pollock Country Park (home of Pollock House and the Burrell Collection). The sawmill was originally powered by a waterwheel, and then ‘upgraded’ with the installation of two ‘modern’ turbines; a Mccormicks Holyoke Turbine in 1890 and a Waverley turbine around 1900. These turbines are beyond repair and will be removed and replaced with a single open flume Francis turbine generating some 60kW from a 1.75m head. One feature of note is the fact that the sawmill equipment remains largely intact; saw-blades, benches, belts, and gearing, providing the opportunity for it to be brought back to working condition albeit driven by an electric motor – powered by the new turbine!
Gordon Black has been confirmed as a speaker at All Energy in Glasgow on May 4th. He will be talking about ‘Pico Hydropower – less than 10kW. The presentation title is ‘One Megawatt of Hydropower for Scotland – One KiloWatt at a Time!’
BabyHydro are delighted to announce the commencement of generation at Westerhall Farm near Langholm, on a 14kW, low-head scheme. The project uses a Bluestream crossflow turbine built by Ecowave Systems, based in Somerset. The scheme is based on an existing dam, and uses a washover screen to ensure the copious amounts of debris and gravel do not obstruct the intake.
BabyHydro took the project through consents, full detailed design, project management, as well as turbine installation and commissioning.
The 500kW hydropower scheme on the Annet Burn in Doune, designed and project managed for Moray Estates Development Company by babyHydro, has been commissioned and is now generating.
Auchmore Farm’s 100kW hydro scheme near Muir of Ord has been commissioned by Gilkes and is running at full capacity. Known as ALF Burn Hydro (named after the Allt Fionnaidh burn on which it is built), the scheme was taken through feasibility and consents, as well as tendering and management of construction, by babyHydro Ltd. The project is a collaboration between two landowners and had the added requirement to safeguarding water quality and flows for the Muir of Ord distillery downstream. The project was designed by Campbell of Doune and built by GS Campbell Contractors (no relation).
May 2014 – opening ceremony
Dawyck Botanic Gardens enjoyed a visit from Energy Minister Fergus Ewing to open their new hydropower scheme, making it the first Carbon Neutral botanic gardens in the UK! Every aspect of the scheme, from initial survey through to construction was managed by babyHydro.
the hydropower intake at ‘Dynamo Pond’ – named after the Victorian era hydropower that lit the house up in the early 1900s
Dawyck is one of the finest arboreta in the world, so aesthetic concerns were high on the list of considerations
The powerhouse is a functional building yet also merges seamlessly into its surroundings, clad in larch and echoing the style of the the main visitor centre with a sedum roof. This one’s so beautiful Scottish Ministers sometimes enjoy posing outside it!
