> Title:  Another suggestion for the title of this artifact is Transport Artifacts, which can refer to either or both Transmission and Distribution.
> I believe we should allow for alternate Transport Artifacts.  In fact Transport is just a Product in EMIX that moves another Product  (energy) from one location to another usually for various fees or prices and sometimes requiring compensation for losses either in kind or by a financial payment.
> ISO/RTOs and other Transmission Operators charge both Access Fees and MWH fees.  In ISO/RTOs the MWH fees change for every delivery interval.  In such nodal markets, the difference between any two nodal prices er MWH cpan be divided into a congestion price and a marginal loss price.  These prices or the total can be negative or positive.
> I suggest that our IRC participants in EMIX provide a sample Transport Artifact that captures nodal congestion and marginal loss pricing.  A complexity is that marginal losses are higher than marginal losses which generates excess revenues to the ISO/RTOs which are rebated to customers.
> In addition to the above ISO/RTO Transport Artifact we would need an artifact for forward congestion revenue rights which are a forward purchase of financial transmission rights.
> I have never heard of Transmission or Distribution being priced on a mileage basis.  A mileage based Transport artifact as in the wd09 draft could be defined, but don't see much value.  And with extensibility to create new Transport Artifacts we can let other do it as needed.
> For distribution there are various distribution tariffs that may involve energy, demand and loss compensation.  These charges will also depend on customer class (residential,C&I etc.) voltage level.  We should provide some illustrative Transport artifacts for Distribution Service, but rely on extensibility for specific distribution tariffs.
> We should also provide an example non RTO/ISO transmission tariff artifact.
> In all of the about we are only trying to represent the results of tariff or market calculations with prices or a loss factors and not how the prices and loss factors are determined. .
