The Northern Territory Government says a milestone has been reached for its $45 million big battery project – known as the Darwin-Katherine Battery Energy Storage System (DK BESS).
All 192 batteries – each weighing 3.5 tonnes – have now been installed for the 35 MVA BESS, with Construction and pre-commissioning also complete, Chief Minister, Eva Lawler said today.
She said Territory Generation was continuing to work collaboratively with key stakeholders to begin rigorous testing before the BESS comes online later this year.
“Battery technology will play a significant role in our target of reaching 50% renewable energy consumption by 2030,” the Chief Minister (pictured) said.
The Government also today announced a second large scale battery storage project.
“To further support our grid, expressions of interest were opened for the DK BESS 2 project. Assessment of submissions is underway to understand industry capability, and successful applicants will be asked to put forward a proposal for the project,” said Ms Lawler.
The DK BESS 2 project will see large scale batteries distributed across locations on the Darwin-Katherine power system to boost capability.
Ms Lawler said the new project will deliver fuel savings and enable more solar renewable energy penetration by providing essential frequency and voltage control services. Commissioning is targeted from 2026 onwards.
“The DK BESS and DK BESS 2 are an important part of our transition to a renewable energy future. We are able to invest in our power grid because we own our assets like Territory Generation, Jacana and Power and Water.”
“By owning our assets we can keep power prices low. Only a Territory Labor Government will keep our assets in the hands of Territorians,” she said.
Together, these two BESS projects satisfy Darwin-Katherine Electricity System Plan requirements for the installation of up to 105 MW of high-specification batteries.
A major part of the Darwin-Katherine Electricity System Plan, the first DK BESS is forecast to deliver cost savings of around $9.8 million per year, paying for itself in about five years from connection to the grid, and delivering annual carbon emission savings of 58,000 tonnes.
“This project will secure our energy supply for Territorians and stabilise our grid as we move towards integrating more renewable energy into our power use,” said Minister for Renewables and Energy, Kate Worden.
“As we move towards a future where renewable energy will play a greater part in our power supply, the DK BESS and DK BESS 2 projects will facilitate a major part of this change.
“By owning Territory Generation and Power and Water, the Territory Labor Government can assure Territorians we will keep power prices down.”
Territory Generation CEO, Gerhard Laubscher said the battery energy storage system projects will play a critical role in advancing renewables in Darwin-Katherine and other power systems across the Northern Territory.
“Adding more battery energy storage systems to Territory Generation’s portfolio will not only enable more renewables and efficient generation dispatch throughout the energy transition, but also fosters the evolution of technological innovations and further supports grid resilience,” he said.
