For the past couple of years DETA has been working with Hanmer Springs Thermal Pools and Spa (HSTPS) to make better use of their geothermal methane, which is a byproduct of their pool heating activities. We initially worked with HSTPS to develop some options for what to do with the gas, and in tandem identified that a Capstone turbine would be the best fit for site – the first installation of a turbine generator in New Zealand.
DETA undertook schematic design, and took the project through delivery of the project within an operating site. The result provides HSTPS with upwards of $50,000 per year of generated energy, with a safer, more resilient infrastructure. The project ran about as smoothly as it could (given the contractors hadn’t worked with such a unit before) and we’ve learnt a lot about the system. We’re really pleased to help deliver a great result for HSTPS, and show that this type of technology can be rolled out economically, and successfully, at small scale.
