Hydropower is a widely understood source of renewable electricity with the opportunity of continuous, reliable generation over many years a key benefit.  Many hydro stations operate with a high capacity factor, generating at maximum power for long periods each year.

It is vital that hydro schemes are carefully planned so that the environmental benefits of clean renewable energy generation are realised with minimal disruption to river ecology. At many ‘low head’ sites, the installation of hydropower provides an opportunity for local environmental improvements such as the installation of a fish pass at locations which were formerly barriers to fish movement.

It most countries hydropower schemes are strictly regulated and require appropriate environmental permissions.

In the United Kingdom and other European countries, The Water Framework Directive and Eel Regulations (2015) have new implications for how all hydropower is implemented.

Design of intake systems involving flow splits, fish passage and self-cleaning screening systems are now key project elements which we will help you implement.

In the UK regulatory services are provided by the Environment Agency (England)Natural Resources Wales, Scottish Environmental Protection Agency and Northern Ireland Environment Agency.



Hydromatch Consulting will  navigate the regulatory system to achieve the best results for both the environment and your hydro project.

Our project documentation is concise and clear so that the design proposals are illustrated in a manner which can easily be interpreted by all stakeholders including regulators.

We have extensive experience of modelling hydro system behaviour under changing river conditions and under different regulatory principles. We use software found at Hydromatch Online to rapidly predict changes to energy generation and illustrate impacts for river flows.




We use our experience of scheme optimisation and planning to implement projects that maximise return on investment.

Whatever scale, all hydro projects require a detailed and rigorous approach to design and development.  For new proposals, we will give you an informed and objective view on viability, rapidly identify potential challenges and help to streamline the development.

Where possible, we will provide a range of alternatives and enable the client to take a lead in design decisions.

Dean Forest Railway 11 kW Hydropower Scheme

Details of the proposed scheme:

System type: Crossflow Turbine Power output: 11 kW
Developer: Dean Forest Railway Co. Ltd Design Conditions: H = 4.5 m
Q = 0.40 m3/s
Location: Lydney, Gloucestershire Expected Generation: 68 MWh p.a.


This micro-hydro scheme is proposed on the site of the Dean Forest Railway at Norchard Drift. The station is run by the volunteers of the Dean Forest Railway Society who’s objective is to preserve the last remaining section of the Severn & Wye Railway.

The scheme is to be constructed at the outfall of a culvert which runs under the railway into the River Lyd. Pico Energy have designed a scheme to fit in with the existing topology and modelled it using 3D CAD, shown in the montage above. Consents are currently under way with abstraction license and planning permission already obtained by Pico Energy.

The scheme is planned to connect with the supply for the station, helping to meet its electricity demand and improve the railways long term viability.
