Residents can now trade the electricity generated on their rooftop, and stored on batteries in their garage without the need for an energy retailer. The Power Ledger system uses blockchain technology to allow residents to trade electricity amongst themselves at a price greater than available feed-in tariffs but lower than residential retail tariffs, providing an incentive for more developers to install rooftop PV on strata-titled developments. The peer-to-peer trading system allows property owners and residents to access the benefits of rooftop photovoltaics in a clear and transparent way, generating significant savings for electricity customers, and maximising the value of investments in sustainable energy infrastructure. Their hope; through adopting the Power Ledger system, consumers and businesses will be able to participate in the roof-top solar revolution, drive down resident power bills and contribute to the reduction in greenhouse gas emissions.
