Cheap solar electricity will be traded between neighbouring residents in apartment blocks in Western Australia, enabling peer-to-peer (P2P) trading of electricity in a project supported by the Australian Renewable Energy Agency (ARENA).
White Gum Valley, a residential development near Fremantle, Western Australia, has rooftop PV installed on its blocks. A modest 53.6kW solar PV system has been paired with a 150kW lithium-ion battery energy storage system on Evermore, one of the apartment blocks.
Using Power Ledger, a blockchain-based technology developed by a local firm will be used to provide a so-called ‘transactive’ layer to the management of the solar-plus-storage installation. Residents will be able to freely sell their power to one another, allowing those with surplus production, for example, to sell power to their neighbours as required.
