Energy Interoperation Version 1.0 Committee Specification is now complete and published in the OASIS archives. All license rights as defined in the specification are now available to developers and other users of the work product. The Acrobat PDF form is authoritative for the specification; the schemas and WSDL files are authoritative for machine-readable artifacts.

This work product is in the latter stages of the Smart Grid Interoperability Panel Catalog of Standards process as of late March, 2012.

Implementation work is in progress, including that of the OpenADR Alliance. In addition, two open source projects implementing Energy Interoperation 1.0 and/or profiles are starting up; more details will be posted here when known.

We strongly encourage feedback from users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of OASIS work. All previously submitted comments (for this work as well as other works of the TC) are publicly archived and can be viewed in the Energy Interoperation Issue Tracker archive.

Energy Interoperation relies on the OASIS EMIX Specification for communication of price and product defintion. The final published version of Energy Market Information Exchange (EMIX) Version 1.0 can be found in the OASIS archives; the final published version of WS-Calendar 1.0 is also in the archives.

Price and product definition are actionable information. When presented with standard messages conveying price and product, automated systems can make decisions to optimize energy and economic results. In regulated electricity markets, price and products often are defined by complex tariffs, derived through political processes. EMIX defines the information for use in messages that convey this actionable information. An essential distinction between energy and other markets is that price is strongly influenced by time of delivery. EMIX conveys time and interval by incorporating WS-Calendar into tenders, contracts, and performance calls.

EMIX was prepared in response the the NIST SMart Grid Roadmap and the Smart Grid Interoperability Panel (SGIP) Prioirity Action Plan 03 (PAP03). It is based upon WS-Calendar for the common communication of time and schedule (PAP04) and is used extensively in Energy Interoperation (PAP09).

OASIS and the EnergyInterop TC welcome your comments. To submit comments, click the "Send A Comment" link on the EITC home page and follow the instructions to subscribe to the energyinterop-comment email list, then send comments to that list. If you are a member of the TC, please use the Jira tracking tool to submit comments instead.

The Energy Interoperation TC works closely with the OASIS Energy Market Information Exchange (eMIX) TC and the OASIS WS-Calendar TC, which respectively are developing standards for exchanging pricing information and product definitions in energy markets and common schedule information.

Participation in the Energy Interoperation TC is open to all interested parties, including: implementers of facility agents, embedded communications clients in control systems, and gateways; Independent System Operators; providers or aggregators of energy provision, curtailment, and use; and operators of transmission, distribution, and utilities.

Contact member-services@oasis-open.org or the co-chairs for more information on joining the TC.


The Energy Interoperation TC works to define interaction between Smart Grids and their end nodes, including Smart Buildings, Enterprises, Industry, Homes, and Vehicles. The TC develops data and communication models that enable the interoperable and standard exchange of signals for dynamic pricing, reliability, and emergencies. The TC's agenda also extends to the communication of market participation data (such as bids), load predictability, and generation information.
