Power Ledger is a decentralized energy exchange platform. It incorporates energy applications, such as a P2P energy trading application that allows businesses to host trading on the platform. This technology enables the sale of surplus renewable energy generated at residential and commercial developments (including multi-unit/multi-tenanted) connected to existing electricity distribution networks, or within micro-grids.

POWR is an Ethereum-based token that fuels the Power Ledger Ecosystem. POWR tokens serve as access permisson tokens, allowing the Application Hosts and their consumers to gain access to the P2P trading features and other Power Ledger applications. To synchronize the ecosystem globally and create cross-market electricity compatibility, a second token, Sparkz, is used in Power Ledger's ecosystem transactions. Applications Hosts may convert their POWR tokens to Sparks when the ecosystem has been accessed.
