Glenmore Control Panel Refurbishment

Glenmore Control Panel Refurbishment

The Glenmore hydro scheme was originally installed in 1936 and retained a large proportion of the original equipment, including the refurbished Gilkes turbine. It is rated at 100kW. The scheme had some remedial works done over the years but had experienced serious issues with the generator and required a solution to address these issues and modernise the plant.

Inverhaggernie Intake Refurbishment

Inverhaggernie HEP 3 km northwest of Crianlarich was built with a side intake, which since construction, suffered blocking from vegetation that significantly reduced production and consumed a large number of man hours in trips to clean the intake. Dulas had previously done work for the scheme owner, upgrading the control panel by fitting a SCADA for improved monitoring, data logging, remote access/communication, installing new PLC Code and recommissioning the plant.

Balnacarn Hydro Scheme

Balnacarn Hydro Scheme

Balnacarn is a 700kW high head scheme located in Glenmoriston, near Fort Augustus. Dulas was commissioned by Dulas Hydro Generation Ltd to deliver the scheme as a turnkey design and build contract. The scheme has one intake and 1.5 km of pipeline. The pipeline passes through Forestry Commission Scotland land and required consideration of future harvesting activity. The intake is fitted with AquaShear Coanda screens and is accessed using a 1.5 km access track that was constructed for the scheme.

Iwrch Hydro Scheme Refurbishment

The original developers of this scheme expected to produce 380kW. However, it was never fully commissioned and only ran for 7 hours before being shut down to prevent serious damage to the equipment. Dulas were contracted to investigate and implement the remedial actions required to ensure the scheme could run. During this process Dulas Hydro Generation Ltd acquired the scheme. Dulas now provides Operation and Maintenance services.
