Subject: 15-day Public Review for Retail Block & Tier Prices using EMIX 1.0

The OASIS Energy Market Information Exchange (EMIX) TC members [1] have produced an updated Committee Note Draft (CND) and submitted this specification for 15-day public review:

Retail Block & Tier Prices using EMIX 1.0
Committee Note Draft 02 / Public Review Draft 02
14 June 2012

Specification Overview:

This Note describes how an application using the EMIX information model can receive Full Requirements Block & Tier Tariffs, (which we abbreviate Block & Tier) and describes how the information can be used by any model rich enough to encompass this sort of price information. 

TC Description : 

The OASIS eMIX TC works to define standards for exchanging energy characteristics, availability, and schedules to support the free and effective exchange of information. Better communication of actionable energy prices will help enable and expand efficient markets that satisfy the growing demand for lower-carbon, lower-energy buildings, net zero-energy systems, and supply-demand integration that take advantage of dynamic pricing. Businesses, homes, electric vehicles and the power grid will benefit from automated and timely communication of energy price, characteristics, quantities, and related information. 

eMIX focuses on methods of exchanging market information consistent with the OASIS Blue approach, encompassing consistency, transparency, and security. 

The eMIX TC works closely with the OASIS Energy Interoperation TC and the OASIS WS-Calendar TC, which respectively are developing Web services-based information and communication models for exchanging dynamic pricing, reliability, and emergency signals and information on energy market participation (such as bids), load predictability, and generation, and common schedule information. 

Public Review Period:

The public review starts 22 June 2012 and ends 7 July 2012. The specification was previously submitted for public review [2]. This 15-day review is limited in scope to changes made from the previous review. Changes are highlighted in the included diff-marked PDF file.

This is an open invitation to comment. OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work.
