In many countries, hydroelectric power plants are a source of clean, renewable and reliable energy, which can be operated economically over extremely long periods of time.

Mott MacDonald assists national and local governments, public and private utilities, developers, contractors, investors, banks and funding agencies to realise these benefits.

Hydropower represents an excellent investment with substantial benefits for the population served, including lower greenhouse gas emissions than most other forms of power generation.

Mott MacDonald assists national and local governments, public and private utilities, developers, contractors, investors, banks and funding agencies to realise these benefits.

The development of such projects requires not only knowledge of the technical aspects of the construction of individual plants, but also an understanding of the social, political and environmental conditions of sites under consideration and the institutional, financial and economic regimes within which they operate.

From multidisciplinary technical expertise to risk and asset management, Mott MacDonald provides an essential service through all stages of project development for both new schemes and plant refurbishment and uprating. Our services cover every element from initial reconnaissance, feasibility and environmental impact studies, to civil, mechanical and electrical design, commercial and technical contract documentation, to project management and supervision of implementation. Through our core of hydro specialists, access is available to the extensive resources of one of the world’s largest engineering consultancies.

With an involvement in hydropower development spanning more than 70 years, Mott MacDonald has built up an impressive track record.
