Subject: Public Review of EMIX v1.0

To OASIS members, Public Announce Lists:

The OASIS Energy Market Information Exchange TC has recently approved the following specification as a Committee Draft and approved the package for public review:

Energy Market Information Exchange (EMIX) Version 1.0

Energy markets have been characterized by tariffs and embedded knowledge that make decision automation difficult. Smart grids introduce rapidly changing products and product availability, with associated dynamic prices. Lack of standardized of messages conveying market information has been a barrier to development and deployment of technology to respond to changing market circumstances. 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. These tariffs convey the price and product information to making buying and selling decisions easier. The same information can be derived from market operations in non-tariffed markets. 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. Energy for sale at 2:00 AM, when energy use is low, is not the same product as energy for sale at the same location at 2:00 PM, during the working day. EMIX conveys time and interval by incorporating WS-Calendar into tenders, contracts, and performance calls. Not all market information is available in real time. Present day markets, particularly wholesale markets, may have deferred charges (e.g. balancing charges) that cannot be determined at point of sale. Other markets may require additional purchases to allow the use of the energy purchased (e.g. same-time transmission rights or pipeline fees when accepting delivery on a forward contract). EMIX is useful for representing available price and product information.

The public review starts today, 17 November 2010, and ends 17 December 2010. This is an open invitation to comment. We strongly encourage feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of OASIS work. We also welcome interested parties to join the TC as it continues to further development of its specifications. This work 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). Please feel free to distribute this announcement within your organization and to other appropriate mail lists.

More non-normative information about the specification and the technical committee may be found at the public home page of the TC at [1] below. Comments may be submitted to the TC by any person through the use of the OASIS TC Comment Facility which can be located via the button marked "Send A Comment" at the top of that page, or directly at [2] below.

We also call your attention to the OASIS IPR Policy applicable to the work of this technical committee, which can be found at [4] below. All members of the TC should be familiar with this document, which may create obligations regarding the disclosure and availability of a member's patent, copyright, trademark and license rights that read on an approved OASIS specification. OASIS invites any persons who know of any such claims to disclose these if they may be essential to the implementation of the above specification, so that notice of them may be posted to the notice page for this TC's work, at [5] below.

OASIS and the EMIX TC welcome your comments.
