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.

Submitted comments (for this work as well as other works of that TC) are
publicly archived and can be viewed at [3] below. All comments submitted to

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.
