IEC TS 62325-503:2014

Framework for energy market communications - Part 503: Market data exchanges guidelines for the IEC 62325-351 profile

IEC TS 62325-503:2014(E) is a technical specification intended for European electricity markets, and specifies a communication platform which every Transmission System Operator (TSO) in Europe may use to reliably and securely exchange documents for the energy market. Consequently a European market participant (trader, distribution utilities, etc.) could benefit from a single, common, harmonized and secure platform for message exchange with the different TSOs; thus reducing the cost of building different IT platforms to interface with all the parties involved. This also represents an important step in facilitating parties entering into markets other than their national ones. Keyword: deregulation of energy market
