Hydroelectric power plants are a source of clean, renewable
and reliable energy that can be operated economically
for many years. Hydropower produces lower greenhouse
gas emissions than nearly all other forms of power
generation, represents an excellent investment for the
countries concerned and offers substantial benefits for the
population served. Mott MacDonald assists national and
local governments, public and private utilities, developers,
contractors, investors, banks and funding agencies to realise
these benefits.

                                                       Hydroelectric power plants use simple and robust technology but incur high

                                                       Mott MacDonald offers a full range of engineering services in this field,
                                                       including the initial engineering survey and testing, uprating of generation
                                                       plant, and refurbishment and replacement of parts to give extended life.
                                                       We also have experience of investigating problems – such as mechanical or

                                                       The initial engineering survey stage is a key part of refurbishment work. We
                                                       use a wide range of testing methods to obtain information on the condition of
                                                       plant and structures and to determine appropriate refurbishment or remedial
                                                       works. Our experience includes projects involving runner replacement for
