Geoff Henderson’s brief biography
Geoff Henderson is CEO and Director of Windflow Technology Ltd, a company which he and four other directors established in 2001 when they successfully raised equity funding to build the first Windflow turbine. This innovative wind turbine is breaking new ground in terms of design for fundamental fatigue load reduction, in particular gearbox loads, for synchronous generation and for local manufacturing. The first 500 kW Windflow turbine was completed near Christchurch in 2003 and the first production batch of 5 turbines was completed in 2006 for a 97 turbine wind farm near Palmerston North. Windflow now has a continuous production of at least 5 turbines a month.
Geoff is a graduate of Canterbury University with an honours degree in Mechanical Engineering. He graduated in 1981 and then spent 3 years working in Auckland for Worley Consultants Ltd as Energy Systems Engineer before heading overseas in 1984.
Geoff has 20+ years in the wind industry and is a recognised global wind expert. He spent seven years overseas which included 2 years working on wind farms in California and four and a half years in England for a wind power R&D company, Wind Energy Group Ltd. During this time he invented a system of power control, the Torque Limiting Gearbox system, for which he has patents in New Zealand and other countries. He became project engineer for Wind Energy Group’s flagship commercial wind turbine, the 33 m, 300 kW “MS3”. This involved managing the engineering design of all aspects of the turbine, including blades, drive-train, tower and electrical sub-assemblies. He was also project engineer in an R&D project testing the fatigue strength of blade-root joint between steel studs and the wood-epoxy blades.
He returned to NZ in 1991 to set up his own company, Wind Torque Limited to promote windmill manufacturing and provide consultancy services. In 1992 he set up another company, Aeolian Property Company Ltd, to purchase a prime piece of wind farming land in the Palmerston North area.
In 1994 he received the Communications Award from the Institution of Professional Engineers NZ (IPENZ) for his “outstanding contribution to the public affairs of the Institution and the engineering profession as a proponent of wind power in New Zealand”. Geoff was a finalist for the 2008 Ernst & Young Entrepreneur Of The Year.
His entrepreneurial efforts since 1991 have culminated in:
2000: the formation of Windflow Technology Ltd (now listed on the NZAX)
2003: the construction of the first Windflow turbine
2005: the establishment of an independent wind farm developer, NZ Windfarms Ltd which was floated through public share offerings in November 2005 and June 2007 (now listed on the NZSX)
2007: The establishment of a production line for at least 5 Windflow 500 turbines a month and adjoining offices
Geoff is a Chartered Professional Engineer and a Fellow of IPENZ. He is a registered professional engineer in California. He was a founding director of the NZ Wind Energy Association. He is also director of the Aoelian Property Company Ltd and four companies in which Windflow has shares, Wind Blades Ltd, Windpower Otago Ltd, Windflow Hawaii Ltd (non-trading) and Pacific Windfarms Ltd (non-trading).
