Most of the discussions in the document imply that there is no distribution grid delivery constraints (i.e., no distribution congestion).

      3.3 Scope of Energy Interoperation Communications
      While the bulk of examples describe the purchase of real power, emerging energy markets must exchange economic information about other time-sensitive services
      For example, delivery of power is often constrained by delivery bottlenecks. The emergence of distributed generation and plugin Electric Vehicles (PEV) will exacerbate this problem. EMIX includes product definitions for tradable congestion charges and transmission rights. Locational market prices in distribution may come to mirror those already seen in transmission markets.
      Other services address the direct effects of distribution congestion, including phase imbalances, voltage violations, overloads, etc.
      These market needs introduce different market products, yet the roles and interactions remain the same. Intelligent distribution elements, up to an intelligent transformer, could be sometimes a VEN, sometime a VTN.
      A description of the tariffs or market rules to support these interactions is outside the scope of this specification. The interactions patterns were developed to support them in markets in which they are required.

      Description

      With unbalanced nature of the distribution grid in the North America, and with emergence of distributed generation and plug-in Electric Vehicles (PEV), the grid reliability will be playing an important role in establishing pricing signals.. Similar to the wholesale markets that transmission congestion led to the concept of locational pricing (LMPs), distribution congestion (phase imbalances, voltage violations, overloads, etc.) could play an important role determining locational retail pricing signals as well.
