Hydropower

SEPA supports the development of renewable energy in Scotland, including hydropower. However, even small hydropower schemes have the potential to adversely affect the water environment. SEPA aims to ensure that an appropriate balance between promoting hydropower and protecting the water environment and other water users is always achieved. This balancing determination will be in line with the policy statement external link issued by the Scottish Government in January 2010.

If you are considering developing a hydropower scheme, you should refer to the SEPA Guidance for developers of run-of-river hydropower schemes. This sets out how SEPA intends to achieve Scottish Ministers' policy objectives and contains guidance on the developments that are likely to be acceptable in the context of the Ministers' policy statement. Emphasis will be placed on supporting hydropower developments which can make a significant contribution to Scotland's renewables targets while also minimising any adverse impacts on the water environment.

If you are in the process of developing a hydropower scheme, this section of the website contains information and guidance which will help you with your application. It explains the process of applying for a water use licence and the minimum information you will need to provide SEPA in support of your application. These pages also highlights where other consents are necessary for a development and how these may interact with the SEPA determination.

Information and guidance is available on the following:

  • Regulation
    Information on the regulation that applies to hydropower schemes
  • Applying for a licence
    Guidance on the application process, relevant consents that are required and environmental standards
  • Supporting information
    Guidance on the general information you are required to supply in support of an application, and details of what is required in relation to hydrological data, fish and fish habitats, and protected areas and species.
  • Useful links
    Details of organisations that may be helpful sources of further information


This guidance is also available in a single guidance document which you can download.
