Western Australia Confirms Residential Battery Storage System Electricity Exports

The Energy Minister of Western Australia, Mike Nahan has made public that battery storage and electric vehicle (EV) systems will be able to transmit excess power to the main electricity grid from 1st December, 2015.

Dr Nahan stated that at the moment, the only batteries being installed by solar developers in Western Australia are the non-exporting batteries; but the new move will open doors for the battery storage revolution.

“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,” he said.

“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.”

Western Australia Greens spokesperson on Energy, Robin Chapple MLC, pinpointed on the matter in Parliament earlier this year and applauded the move.

“Thankfully, logic has prevailed and the government has very quickly amended its use of language in this agreement to allow for the use of new battery technologies,” Mr. Chapple said.“Battery storage systems are going to completely revolutionise the way that we use energy, offering West Australians the opportunity to simultaneously save money and cut their household emissions.”

So far, more than 175,000 residential solar PV arrays have been installed on the South West Interconnected System. The upgrading of the systems by current solar developers will make residential battery storage system in WA is anticipated to be more popular.

The rate at which solar panel systems in WA is are increasing is alarming.

“Around 1,750 residential solar PV systems have been installed each month on the SWIS during this year”, Dr Nahan announced.

Energy Matters too expressed their satisfaction and indicated the benefits that will result from installing such upgradeable solar system in Perth.

Based on the analysis by Energy Matters “A 5.3kW battery-upgradeable solar power system installed in Perth can return a financial benefit of between $1,585 and $2,279 a year; without storage added”.
