Under Discussion Topic

Summary of the topic to be discussed with the development team

In a TEA being conducted, there ends up being two resources demanded by the "grid" component. These resources are called electricty1 and electricity2. At this point in the workflow both resources are in the same units and their total activity needs to be accounted for in the cashflow.

Should a user be able to specify something like:

<driver>
<activity>electricity1,electricity2</activity>
</driver>

With the caveat that they are expected to be in the same units and we will not catch any errors due to un-matching units?

For Change Control Board: Issue Review

This review should occur before any development is performed as a response to this issue.

• 1. Is it tagged with the under_discussion type?
• 2. If implemented, it will add a new requirement?
• 3. Is a rationale provided? (Such as explaining why the improvement is needed )

For Change Control Board: Issue Closure

This review should occur when the issue is imminently going to be closed.

• 1. The discussion determined the addition of a new task issue?

Is there a functional difference between having the for Grid A take in electricity1 and electricity2 versus having Grid A take electricity1 and a new (dummy) Grid B take electricity2? I guess it would be up to the user to make sure Grid B is identical to Grid A.

@GabrielSoto-INL Good question and something I thought about. They would need to use the SyntheticHistory in both grids and could potentially do that. I just wonder if that would cause confusion to the user having to send electricity to two identical grids.
