A new large-scale battery, will be built in South Australia with support from the Australian Renewable Energy Agency (ARENA).
The Minister for the Environment and Energy has announced that the Agency would provide up to AUD12 million (US$9.54 million) in funding toward a 30MW, 8MWh battery at the Dalrymple substation on the Yorke Peninsula.
The battery, the second phase of the Energy Storage for Commercial Renewable Integration (ESCRI) project, is expected to cost around AUD30 million (US$24 million).
ESCRI Phase 1 consisted of a study into the potential for energy storage to benefit the South Australian network. It has allowed key aspects of a utility scale battery, such as revenue generation, to be thoroughly planned ahead of today’s announcement.
The project will supply Fast Frequency Response (FFR), which helps balance the electricity network, particularly in the context of increased levels of renewable energy generation. This capability will also be used to help reduce operating constraints on the Heywood interconnector with Victoria which, in turn, has the potential to place downward pressure on wholesale energy prices in SA.
It will aslo provide contingency power for the Dalrymple service area during a loss of supply. The islanded battery will work together with the existing 90MW Wattle Point wind farm and rooftop solar PV in a microgrid to provide backup local supply until connection to the grid is restored.
Mr Frischknecht said:
"The ESCRI battery will make an important contribution to security and reliability of supply in the context of high renewable energy generation in South Australia.
This is also the first large-scale grid-connected battery to be designed, built and commercially operated in Australia largely with private investment from energy providers.”
“It may not be the biggest battery in the world, but pound-for-pound it will pack a big punch in demonstrating how utility scale storage can contribute to a stronger South Australian energy network.”
The State Government of South Australia is calling for expressions of interest (EOI) from businesses interested in accessing a share of a AUD150 million (US$119 million) Renewable Technology Fund (RTF).
