James Eggleston of Power Ledger
James Eggleston spoke about P2P trading. This class of Platform Application gives retailers the ability to empower consumers (or in an unregulated environment, the consumers themselves) to simply trade electricity with one another and receive payment in real-time from an automated reconciliation and settlement system. He also spoke of the many other benefits such as being able to select a clean energy source, trade with neighbours, receive more money for excess power, benefit from transparency of trades on a blockchain and very low-cost settlement costs all leading to lower power bills and improved returns for investments in distributed renewables.
