Innovation and quality are very much part of Nova Energy’s generation activities. Our electricity generation utilises a range of renewable geothermal energy and clean-burning natural gas facilities. This diversified portfolio has been built up over the years providing us with the skills and knowledge to tackle a wide range of generation projects.
Further renewable energy projects being evaluated include investment into new tidal-generation technologies.
Nova Energy holds interests in highly efficient co-generation plants at Kapuni, Edgecumbe and at Fonterra's milk processing plant in Hawera. These facilities directly utilise Nova Energy's natural gas and expertise to provide our customers with a total energy solution to meet their business gas, electricity and steam requirements.
Nova Energy’s McKee co-generation facility was designed to run on waste gas that was previously flared into the atmosphere. The co-gen plant provides electricity and through the heat exchange process hot water. The hot water is used to process the well fluids from the McKee oil field. The co-gen units are capable of generating 2 MW of electricity which is exported to the local grid.
At Kawerau, in the geothermal-rich Bay of Plenty region, Nova Energy owns and operates a geothermal plant that supplies energy to the local region. This facility - known as TG 2 - utilises geothermal energy to heat a motive fluid in a closed loop system to generate 29 GWh per year of electricity.
Greenhouse gas from Wellington’s Southern Landfill is being used to generate electricity. The landfill gas collection system captures 4 million cubic meters of odorous and environmentally harmful landfill gas each year, this then drives the generation plant. The 1 MW plant generates up to 8 GWh of electricity per year – enough to power 1000 households.
