The purpose of this guidance is to:
- help developers and competent authorities identify, assess, and where necessary, mitigate against impacts on the natural heritage from hydroelectric developments. It is mainly aimed at run-of-river schemes, but refers to low head proposals too;
- help SNH staff formulate our advice on individual applications, particularly at the pre-application stage where we can influence the design of the development. It will help to ensure that our staff take a consistent approach to hydro casework.
