• Giuseppe (Jo) Grilli - Director

    Giuseppe received firstly a Polytechnic Diploma in mechanical engineering and then graduated from the University of Rome in Electrical Engineering in 1963. In 1964 he joined the Italian state owned electricity authority and spent the first 15 years of his professional career in the operation and maintenance of hydropower generation and transmission.

    In 1978 Giuseppe emigrated from Italy to New Zealand and took up a position with the New Zealand Electricity Department (NZED), where he has been the leader of multidisciplinary hydropower engineering professionals, covering project development and implementation, as well as engineering support to the operation and maintenance of hydro power stations.

    Over the years Giuseppe has also gained extensive knowledge of, and direct experience in the specification, maintenance, tuning, troubleshooting and upgrading of turbine governing systems.

    In 1999 he founded his own hydropower consulting practice, Hydropower Engineering Ltd and has provided his professional services to the hydropower industry ever since.

    Giuseppe is the founder of the Hydro Power Engineering Exchange, an honorary member of the International Hydropower Association and a distinguished fellow of the Institution of Professional Engineers of NZ awarded to Giuseppe on 16th March 2012.

  • Joachim (Joe) Pott - Director

    Joe graduated from the University of Stuttgart in Germany, as “Diplom Ingenieur” in Mechanical Engineering in 1996. During his degree, Joe specialised in hydro power at the Institute for Fluid Mechanics and Hydraulic Machinery.

    From 1997 until 1999 Joe started his professional career with Leyland Consultants (now Sinclair Knight Merz) in Auckland where he was involved in project engineering and project management of predominantly hydro projects in New Zealand and overseas.

    Between 1999 and early 2008 Joe was employed by Meridian Energy, New Zealand’s largest hydropower producer, in Production Engineering and Asset Strategy Development positions. Joe’s roles included responsibility for all technical aspects of the Manapouri turbine upgrade project from project inception through to commissioning of the last unit. Joe’s role extended to providing technical advice to the wider Asset Management Team, New Zealand Operations and Growth and Development Directorates. This included extensive involvement in Meridian’s new hydro developments and optimisation of Meridian’s dispatch of existing hydro assets.

    In March 2008 Joe joined the engineering consultancy Hydropower Engineering as a partner and has since been involved in a variety of hydro related projects and assignments.

    Joe is a member of the Institution of Professional Engineers New Zealand and is registered as a Chartered Professional Engineer (CPEng).

  • Joachim (Joe) Pott
  • The engineers at Hydropower Engineering have an unlimited passion for hydropower. In the independent Dam Safety reviews of Meridian’s Waitaki Valley hydro assets, among the values they brought were a vast wealth of engineering expertise, together with an ‘owner’s perspective’ that very few consultancies have the experience to provide. This results in very high quality focused advice, invariably delivered on time.
