Andrew Douglas Garrad (born 8 November 1953) is an engineer and businessman and one of the pioneers of the modern wind energy industry.[1] In 1984 he co-founded the consulting company Garrad Hassan ("GH") which supported the industry through design consultancy, testing, measurements, energy evaluation and technical due diligence. Software and services provided by GH became widely used.
From his school days he has had a strong interest in mathematics. He has a BA in Engineering Science from the University of Oxford and a PhD in theoretical fluid mechanics from the University of Exeter where he studied the boundary-layer flow over dolphins.[2] He built his first wind turbine in 1971 which he erected at his parents' home. His enthusiasm for wind energy was sparked by a lecture by Ernst Schumacher in Oxford, also in 1971.
He has been professionally involved in wind energy since 1979, when he joined the Wind Energy Group.[3] Mathematical modelling remained his main enthusiasm and Garrad Hassan[4] was built on the provision of mathematical models of all aspects of wind energy. His mission for the company was to be able to predict everything from the weather, through the turbines and wind farms to the electricity in the grid and finally the cash flow.[5] [6] In 1984 he wrote the initial version of the wind turbine system aeroelastic code Bladed whose development continues to this day.[7] Data, both measured and predicted, were the main currency of Garrad Hassan and the company produced many other computational tools[8] [6] [9] adopted by the industry. He was heavily involved in the technical due diligence of very large wind farms as part of the project finance process common to big capital projects. GH, together with the offshore consultancy Tecnomare, undertook the first ever floating offshore wind turbine design studies.[10] Although GH specialised in wind energy it also provided parallel services in wave and tidal energy, for example its WaveDyn software for predicting the dynamic behaviour of wave energy devices.[11]
He was one of the pioneers of Chinese wind energy development and was co-Chair, with the Chinese Minister of Electric Power, of the first Chinese International Wind Energy Conference in Beijing in 1995 when there were no turbines in China! Later on, starting at the turn of the century, GH helped shape the newly formed Chinese industry with many design contracts and also strategic advice on the development of their nascent offshore industry.[12]
He is a past-Chairman of the British Wind Energy Association, now Renewable UK.[13] He was President of European Wind Energy Association (EWEA, now Wind Europe)[14] from 2013 to 2014. He chaired Bristol's year as European Green Capital in 2015.[15] [16] [17]
He sold Garrad Hassan to Germanischer Lloyd in 2009 and became President of the combined company, GL Garrad Hassan, and hence was responsible for both consultancy and certification. When he retired in 2015 the renewable energy company had 1,000 staff in 29 countries. In retirement he remains active in wind energy and, in 2019, he was appointed Royal Academy of Engineering Visiting Professor in Renewable Energy by the University of Bristol.[18] In 2023 he was appointed visiting professor in the Department of Engineering Mathematics. His job is to introduce students to the engineering world outside university.[19] In March 2024 he became Chair of the Severn Estuary Commission whose task is to investigate the feasibility of generating electricity from the Severn Estuary in the UK.
