April 6 (Renewables Now) - The government of Australia’s Northern Territory (NT) said yesterday it has approved the procurement of a large-scale battery storage system for the Darwin-Katherine power grid at a project cost of AUD 30 million (USD 18.2m/ EUR 16.9m) as part of the 2030 target to reach 50% renewables.
While details on the project have not been provided, the government said the battery system is expected to earn back the investment in around five years.
The new battery will help absorb more renewable energy from large-scale solar projects and increase the stability and reliability of power supply. By reducing the need for gas-fired spinning reserve, it will save costs of around AUD 6.4 million and cut emissions by around 50,000 tonnes per year, the government said.
The procurement process will be held in the coming months, while the system is expected to go live in the second half of 2022.
The NT government also launched the Household and Business Battery Scheme (HBBS) to promote the installation of behind-the-meter batteries in conjunction with solar photovoltaic (PV) systems.
Under one of two HBBS initiatives, households and business stand to receive a AUD-6,000 grant for the purchase and installation of solar PV systems with eligible batteries and inverters, or just batteries and inverters for those who already have solar arrays.
Secondly, NT-based electricity retail Jacana Energy will offer a new feed-in tariff (FiT) of AUD 0.083 (USD 0.050/EUR 0.047) per kWh to all new businesses and households with behind-the-meter solar installations of up to 30 kW in size.
