Battery storage and electric vehicle (EV) systems will be able to export excess electricity into the network from December 1, 2015 after a historic agreement was reached between Synergy and Western Power.
In a move that will pave the way for the take-up of the next phase of new energy technology, Energy Minister Mike Nahan today announced that the two State Government-owned entities would officially sign off on a non-reference service, which would allow storage systems to export unused electricity onto the South West Interconnected System (SWIS).
"Until now, storage systems have been unable to export electricity onto the SWIS," Dr Nahan said.
"I am pleased that Synergy and Western Power have reacted quickly to developing a non-reference service that can amend the anomaly without requiring the regulator to amend the network access arrangement.
"It has been a significant inconsistency that eligible customers were able to export electricity onto the SWIS from residential solar photovoltaic (PV) systems, but were not able to do so from a battery or electric vehicle storage facility.
"This arrangement now means eligible customers can install battery storage or EV facilities to complement their solar PV systems and export unused electricity onto the network.
"This is an important development given the emerging future trends which forecast widespread installation of solar PV, plus storage systems."
Synergy and Western Power are currently involved in groundbreaking new energy technology trials that partner renewable energy and storage, including the community energy storage facility at Alkimos Beach and a new wave, solar and storage trial at Garden Island.
There are more than 175,000 residential solar PV systems installed on the SWIS, with a total generating capacity of about 440 megawatts
On average, about 1,750 residential solar PV systems have been installed each month in 2015
Batteries are required to meet technical and safety standards to connect to the grid
