The IAI and the BuildingSmart Alliance are old friends.
Most of the energy-related work at the edge of BIM is now in GBXML, Green Building XML, which does not currently have any attributed for energy storage. EnergyPlus, which several on this list know from LBL, is preferred by some for energy modeling as more rigorous. I do not know enough to judge.
Neither one is yet a standard, although there is some interest from the GBXML.org crowd in running their specification through an SDO, while adding some better energy features at the same time. I cannot but speculate on when that might happen.
Let me make some inquiries at CERL and NIBS…

"If something is not worth doing, it`s not worth doing well" - Peter Drucker
While subsequent emails suggest this might be overkill, or at least not completely necessary, it does bring a question. There is an effort underway generically termed Building Information Modeling (BIM). As part of that effort, we and others are developing XML language that describes our products in meaningful terms. It would be terrific if somewhere in our merry band there is someone with intimate knowledge of the BIM effort who might know if this effort could be extended to storage, or perhaps already is.
I spoke to Chuck Eastman, Professor of Architecture at Georgia Tech often credited with developing the concept of BIM in the '70's (though he says incorrectly). He said that the Building Information standard has 10-20 thousand entities defined already, but energy is a huge gap. GSA has sponsored Richard See to work with LBNL and BIM tool software implementers to address this, but they are at an early stage, and still arguing over zonal energy issues. Dr. Eastman is going to send me a link when he returns to his office.
Also, there is a document on BIM based energy analysis (which seems to incorporate the DOE Energy Plus mode and is found at http://63.249.21.136/IAI-MVD/IDM/BSA-002/PM_BSA-002.pdf). If they are not participants in our process already, perhaps they should be. Fortunately, I do know the relevant people at Autodesk, but will await discussion before reaching out.

Can we get one of those 400 people to write some XML for us?!?!
If telephone switch industry is a guide here - this means we already have 3 sets of battery subsystem XML - GE, Hitachi and Samsung - with more to follow. And of course each new model has new XML...

Actually, GE announced such a system last week and is hiring 400 people in Atlanta to staff the new business. It's a substation level product. Also, I have spoken personally with people at Hitachi and Samsung who are testing a 1 MW battery. Such a battery from another vendor is in test operation behind PJM's main offices. So local here takes on a new meaning depending on whether it is truly behind the customer meter, or behind the distribution grid meters (substations and the like), or on a transmission system. Theoretically, batteries of this size could replace generators used for voltage or frequency support.

It occurs to me that local storage can potentially play a role here - depending on its efficiency of course. One can anticipate that future technology will offer higher % there - especially if market forces drive that equation.
Therefore - a future system could offset power surges by drawing on locally stored resources that were captured during off-peak or excess capacity. In fact such a system may notify suppliers that they can "push" excess power to local storage at some pre-determined cost point - and of course also need to indicate that the storage facility is at a certain % level, or if empty - accept units at a higher cost rate.
