GL Garrad Hassan

GL Garrad Hassan is the world's largest independent renewable energy consultancy. The recognised authority on wind for many years, it is now at the forefront of the offshore wind, wave, tidal and solar sectors too.

GL Garrad Hassan is the world’s largest renewable energy consultancy. It offers independent technical and engineering services, products, and training courses to the onshore and offshore wind, wave, tidal and solar sectors. Although the GL Garrad Hassan name is new, the company has a rich heritage. It is borne of the integration of specialist companies that, united under a single brand, form the renewable energy consulting division of the GL Group. GL Garrad Hassan is a consulting company; it has no equity stake in any device or project. This rule of operation is central to its philosophy, something which sets it apart from many other players and underlines its independence.

With a network of local experts around the world, GL Garrad Hassan’s global perspective is informed by local understanding and local resource. The company is uniquely placed to understand the interplay between the technology, geography and environmental conditions, which determine the engineering solutions, and also the policy, economics and regulation, which determine the markets. As a result, its services provide real added-value for clients.  When it comes to credentials, GL Garrad Hassan has plenty: it has been the technical authority on wind power for nearly thirty years; its experts are at the forefront of developments in the wave and tidal sector and its achievements in the field of mechanical renewables are now being replicated in solar, its most rapidly growing sector.
