Our team is made up of reservoir, mechanical, drilling and electrical engineers, geothermal scientists, power station operators and maintenance experts. They support our geothermal development work, along with the operation and maintenance of our five geothermal power stations and the sustainable management of the geothermal resource. Their collective skills and expertise are rare and only a handful of public companies worldwide are large enough to have such a substantial, in-house, geothermal team. Understanding the subsurface environment and managing the precious geothermal resource in a sustainable manner are key to the success of any geothermal development. We have a dedicated team of around 35 subsurface professionals based at Wairākei with international experience, having What would you call worked on geothermal projects in countries such as Chile, Indonesia, USA, the Philippines, and Papua New Guinea. It’s an unparalleled depth of skill.

Case study: Improving environmental performance Wairākei bioreactor – a world first To prolong the life of the Wairākei power station we needed to find a solution to improve the environmental performance of the plant and reduce the impact on the River.

Hydrogen sulphide (H2S) is present naturally in geothermal steam. As a result of the condensing process used

by the Wairākei station, some H2S dissolves into the station’s cooling water, which is then returned to the , impacting water quality. We corrected that by developing the Wairākei Bioreactor – a world first and an award winning solution. Is it possible The bioreactor harnesses the power of billions of naturally occurring bacteria endemic to the Waikato River to treat the water before it is returned to the river. The bioreactor is designed around a large network of 378 kilometres of underground to innovate pipes that create an environment for the bacteria to live and grow in. Cooling water from the power station flows into the bioreactor and passes through the pipe field where the bacteria naturally remove up to 90%

of H2S from the cooling water before it is returned back to the Waikato River. The Wairākei bioreactor for the long term, This is the first bioreactor in the world to be used in geothermal protecting assets electricity production. and the future of natural resources?
