HANDSAL handles the message traffic that does not pass through a central market hub. Electricity suppliers, grid companies and balance responsible parties exchange structured messages directly between themselves every day - invoices, delivery schedules, product data. That bilateralMessages travel directly between two parties, without passing through a shared hub. The opposite of the centralised model Elhub is built on. Also called point-to-point. traffic is usually solved either with an expensive closed message broker, or with home-built solutions that have no monitoring, quarantine or alerting when something fails to arrive. HANDSAL is a self-hosted gateway supporting EDIELThe Nordic standard for message exchange in the power market. In Norway it now means Elhub's XML messages, in Sweden it is still EDIFACT., AS4Open OASIS standard for secure message exchange over HTTP - the transport protocol required by Peppol, increasingly seen in European power-market messaging too., ECPEnergy Communication Platform - EU-standardised interface for secure data exchange between actors in the European power market., PeppolEuropean network for e-invoicing and e-procurement - uses AS4 as its transport protocol. Norway is among the countries with mandatory e-invoicing via Peppol for the public sector. and EDIFACTUN standard for electronic data interchange. In the power market it is used where messages go directly between market participants, and in systems that predate the national hubs. in one solution, with routing, acknowledgement and queue handling built in. The name is Old Norse: a handsal was the handshake that made an agreement binding.
