Testing and commissioning of Kurri Kurri Power Station continues to progress. In recent weeks, we have tested using gas and have successfully started providing electricity to the grid.
To complete commissioning, it is important that we finalise our first generator's testing on diesel. This will ensure the power station can reliably operate on its diesel back-up fuel at the infrequent times the network is under pressure and diesel generation is required to maintain reliable electricity supply to homes and businesses.
Testing will recommence on Sunday 24 August, and will continue for 12 days over a two to three week period. The testing will take place at different times between 3pm and 10am.
We understand testing in July on the back-up diesel fuel generated visible emissions and an odour that caused discomfort and concern. The level of emissions and odour was not expected and was associated with starting up a brand new generator, combined with strong winds.
Working with the manufacturer, we have identified the best approach to minimise the plume and odour caused when testing on diesel. This involves starting the generator using gas, and then switching to diesel.
Snowy Hydro is also working closely with the NSW Environmental Protection Authority to ensure impacts remain within strict environmental limits.
When fully operational, Kurri Kurri Power Station is designed to run only for a minority of the time, when electricity demand is high and renewable generation is limited. It will operate using gas as its primary fuel, with diesel only being used as a backup.
Kurri Kurri Power Station will play an important role in preventing blackouts and enabling Australia's decarbonisation. It will provide 660 megawatts of electricity when it's needed most, allowing more wind and solar generation to enter the grid. It will operate using gas as its primary fuel, with diesel only being used as a backup.
