Nova Energy's peaker

Electricity Generation

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. 

Landfill Gas 

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.
