When the sun don’t shine: 8 batteries that store solar energy
Solar storage goes under the spotlight in Australia

A historic agreement reached between Synergy and Western Power will allow battery storage and electric vehicle (EV) systems to export excess electricity into the Western Australian network from December 1, 2015.

The two State Government-owned entities will officially sign off on the non-reference service, which would allow storage systems to export unused electricity onto the South West Interconnected System (SWIS).

The storage systems have been unable to export electricity onto the SWIS but the new service will correct the anomaly without requiring the regulator to amend the network access arrangement.

While eligible customers were able to export electricity onto the SWIS from residential solar photovoltaic (PV) systems, they were unable to do so from a battery or electric vehicle storage facility. The new agreement now allows eligible customers to install battery storage or EV facilities to complement their solar power systems and export unused electricity onto the network.

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.
