Bruce and all --

Some management-style3 questions...

Much of this is structured for the California block and tier tariffs, is it not?
>This is not just for California. BC Hydro used the same structure along with other utilities in different states.

How much is SEP2 information model to reflect that?

>It is fully modeled in the SEP2.

How fluid is that information model? Is it a moving target?  Is it anchored (at least for 2.00) by the block and tier tariffs above?
>The SEP 2.0 pricing model is based on IEC61968 which is a stable model although its 2nd release is still in circulation for comments. In the current SEP 2.0 model, block tiers are contained by TOU but the original CIM model can deal with the other way around (i.e., block to contain tou tiers)

When defining the problem think of Time of Use Intervals as tiers that encapsulate consumption blocks (which are defined in emix as blockPowerFullRequirements). This is the Zigbee slide in the link I provided.


I do not understand enough about what you are proposing to say if it will work. It needs to be reflected in EiQuote somehow. The SE2 Price message I provided does not attempt to get slick with recurrences. They just publish a schedule that looks like above but with dates and times.

Subject: [emix] Tiered Pricing


The solution I believe is to use power:blockPowerFullRequirements (which has tiers) inside each interval through the day. In this way we can state what the tiers are for each hour of the day and have the size (of the tiers) and or prices (for each tier) vary within that interval.


If we are communicating day-ahead communication of tiers, that is all we need.


As a further issue, there may be a desire to template the communications, i.e., to state weekdays vs weekends (assuming they had different price tiers). This we could accomplish by:

1)      Building two unscheduled sequences, as above.

2)      Sending 5 gluons (for M-F) starts referencing one sequence, and two gluons (for Sa-Su) starts.


Alternately, one could want to announce that a particular tiered pricing in in place during the summer months. This could be done by a Gluon with two vavailabilitys (weekdays and weekends), and having each vavaialbility reference the appropriate sequence.


Do we need more than that?
