Subject: Scope questions for discussion


David Holmberg and I had a great conversation today on the scope of EI (which will hopefully feed into section under discussion). I’d like to open up some of my ideas and get your feedback before I propose a few paragraphs for the scope section.

 I’d like to look at the scope from a B2G interface point of view and the questions I suggest we try to answer are:

  1. What information do the buildings need from the electricity grid?
  2. What information does the electricity grid need from the buildings?

 Buildings’ need from the Grid:
-         Electricity prices (various forms such as absolute, relative, level, etc)
-         DR contract parameters – excluding direct load control: A contract can have the following parameters:

   -         Issue time, start time, end time

-         Within the start time and end time there may be a request from the grid for load reduction (%, absolute, relative, etc) (or load increase - when there is too much generation)

       -    Power quality (Do we care how “good” the power we get from the Grid? Probably! What are the indicators to be communicated to a building?
 -    Location of the resources needed

 Grid’s need from buildings:

-         Measured (current, historical) demand
-         Predicted demand
-         Available DR (over next 24 hrs?, 1 week?)
 -   Location identifier (meter, address, grid location indicator?)

 I welcome your comments. All of the above assumes that the meter is the demarcation point. And just to add, the expansion of this to DER can be again categorized as on the utility side and on the building side but should be a super set.
