Most utilities have existing load reduction programs in place that do this kind of analysis via subcontractors who build energy efficiently plans. In my state, you can get substantial energy discounts if you agree to let the system operator control a portion of your electric supply and shut stuff off when there is a peak usage event.
All of these contractors bid on this stuff. If I can pay this guy or some other random consultant guy to do this analysis with more modern techniques, I can get rid of 3-5 energy engineers @150k of payroll and benefits each. That means I win the bid.
I can guarantee you that paying this guy money that will make him do backflips will cost maybe 10% of what it would cost if I went to Oracle or IBM.
You folks who work with this stuff don't understand how poor the tooling is in verticals like this. If you ever have an opportunity to see IBM Watson people in the room with CIOs, take it and try not to shake your head too much. They demonstrate analysis that is much less robust than this of things like help desk tickets, and CIOs think they've met HAL.
