800kW Hydro scheme for Private Landowner

Client - Private Landowner

Project Overview

Dulas’ hydro team have vast experience in both
the engineering of innovative hydro solutions and
the optimisation of pre-existing projects
throughout the UK. Having previously been
extremely satisfied with Dulas’ successful
refurbishment of a hydro scheme, a private
landowner turned to our team once more in order
to construct and install an 800kW run-of-river
hydro project at Crianlarich in Stirling, Scotland.
Situated within Loch Lomond & The Trossachs
National Park, Dulas had to account for a range of
planning and logistical issues resulting from the
remote and exposed intake location.
However, drawing on its extensive expertise in bespoke
hydro, Dulas successfully delivered the scheme on
time, allowing it to be commissioned ahead of the
relevant Feed-in Tari deadline. The scheme is
now up and running and has been of great
economic benefit to the client.

The project was particularly complex requiring a private HV wire and work to accommodate a second turbine in the future, which would boost the scheme’s capacity to 1.2MW.
Dulas steered the landowner through successful planning and CAR licence applications, as well as
the discharge of planning conditions. The team worked to this tight deadline to deliver a detailed
design for construction, while acting as Client’s Engineer, filling several project management roles
and managing numerous contractors involved in the project.
As a result, the team delivered effective and comprehensive decision-making and issue
resolution over the course of the work. Dulas’ experience was also crucial in conducting delicate
negotiations and issue resolution in consultation with Scottish Natural Heritage and the Scottish
Environment Protection Agency.
In addition to commissioning the scheme, Dulas delivered a range of design and technical services
including low voltage electrical design, control panel design and electrical installation.

Outcomes and Benefits

Despite these challenges, and delays on the part of one of the contractors, the scheme was
successfully delivered and commissioned on time, allowing it to meet the Feed-in Tariff deadline.
It was completed to a recognisably high standard, and Dulas received enthusiastic feedback from a
range of stakeholders including the client and the Scottish Environment Protection Agency.
Having chosen Dulas on the basis of an established and successful working relationship, at
Crianlarich the client received a turnkey service built on years of hydro engineering experience.
This ensured that the project moved smoothly through each stage of development, from design
to construction and installation and finally on to commissioning.
