The Open Smart Grid Protocol (OSGP) is a family of specifications published by the European Telecommunications Standards Institute (ETSI) used in conjunction with the ISO/IEC 14908 control networking standard for smart grid applications. OSGP is optimized to provide reliable and efficient delivery of command and control information for smart meters, direct load control modules, solar panels, gateways, and other smart grid devices. With over 5 million OSGP based smart meters and devices deployed worldwide it is one of the most widely used smart meter and smart grid device networking standards.

Protocol layers and features[edit]

OSGP follows a modern, structured approach based on the OSI protocol model to meet the evolving challenges of the smart grid.

At the application layer, ETSI TS 104 001 provides a table-oriented data storage and command system that provides for not only smart meters and related data but for general purpose extension to other smart grid devices. ETSI TS 104 001 is an updated version of the application layer specification that incorporates enhanced security features, including AES 128 encryption, and replaces the previously ETSI GS OSG 001 version. OSGP is designed to be very bandwidth efficient, enabling it to offer high performance and low cost using bandwidth constrained media such as the power line. For example, just as SQL provide an efficient and flexible database query language for enterprise applications, OSGP provides an efficient and flexible query language for smart grid devices. As with SQL, OSGP support reading and writing of single attributes, multiple elements, or even entire tables. As another example, OSGP includes capabilities for an adaptive, directed meshing system that enables any OSGP device to serve as a message repeater, further optimizing bandwidth use by repeating only those packets that need to be repeated. OSGP also includes authentication and encryption for all exchanges to protect the integrity and privacy of data as is required in the smart grid.

The intermediate layers of the OSGP stack leverage the ISO/IEC 14908 control networking standard, a field-proven multi-application widely used in smart grid, smart city, and smart building applications with more than 100 million devices deployed worldwide. ISO/IEC 14908 is highly optimized for efficient, reliable, and scalable control networking applications. The low overhead of ISO/IEC 14908 enables it to deliver high performance without requiring high bandwidth.

Since it builds on ISO/IEC 14908, which is media independent, OSGP has the possibility to be used with any current or future physical media. OSGP today uses ETSI TS 103 908 (PowerLine Telecommunications) as its physical layer. Although a new standard, products that conform to ETSI TS 103 908 prior to its formal adoption have been on the market for many years, with over 40 million smart meter and grid devices deployed.[1]


OSGP is built upon the following open standards.

  • ETSI Technical specification TS 104 001: Open Smart Grid Protocol.[2] Produced by the ETSI Technical Committee for Powerline Telecommunications (TC PLT ), this application layer protocol can be used with multiple communication media.
  • ISO/IEC 14908-1:[3] Information technology—Control network protocol—Part 1: Protocol stack. Published through ISO/IEC JTC 1/SC 6, this standard specifies a multi-purpose control network protocol stack optimized for smart grid, smart building, and smart city applications.
  • ETSI Technical specification TS 103 908: Powerline Telecommunications (PLT);[4] BPSK Narrow Band Power Line Channel for Smart Metering Applications. This specification defines a high-performance narrow band powerline channel for control networking in the smart grid that can be used with multiple smart grid devices. It was produced by the ETSI Technical Committee for Powerline Telecommunications (TC PLT ).

OSGP is supported and maintained by the OSGP Alliance (formerly known as Energy Services Network Association), a non-profit corporation composed of utilities, manufacturers and system integrators.
