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.

                                                       Services for lenders
                                                       Mott MacDonald works closely with lenders and sponsors to address all the
                                                       technical and environmental issues relevant to financing and to understand
                                                       how the business and assets operate. We provide clear analysis and focussed

                                                       Services for contractors and manufacturers
                                                       Today’s market often requires complex contracts for construction and
                                                       equipment supply within tight timescales and margins. In addition to
                                                       Mott MacDonald’s role as designer of both civil works and equipment, we
                                                       offer services in the management of interfaces between the various designers,
                                                       suppliers and builders, and in cost consultancy. These interfaces can pose
                                                       the largest single obstacle to successful achievement of both new build and

                                                       Our integrated services to support both design and construction are designed
                                                       to minimise the risks involved and improve the profitability of any project

                                                       Sustainability through refurbishment
                                                       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
                                                       hydraulic vibration – and advising on the causes of failure of structures
                                                       or equipment and the means of their repair or modification.


                                                       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
                                                       improved efficiency, complete turbine refurbishment and generator rewind,
                                                       investigations of causes of vibration and tunnel lining failure.
