I've modeled a PV with battery storage two ways. First by having the PV and battery operate based on the whole facility's loads by setting the Generator Operation Scheme Type toBaseLoad and the Storage Operation Scheme to FacilityDemandLeveling in the ElectricLoadCenter:Distribution object. Works just as expected. But if I try to operate the object by setting it to track a particular meter it doesn't operate as expected.

If I change only the Generator Operation Scheme Type toTrackMeter the ElectricityPurchased:Facilityand ElectricitySurplusSold:Facility are exactly the same for every hour as BaseLoad. I've verified the meter does not track the whole facility's electricity.

If I change the Storage Operation Scheme to TrackMeterDemandStoreExcessOnSite I get the below error even though I have a name in the field for the meter:

** Fatal ** ElectPowerLoadCenter::setupLoadCenterMeterIndices  Did not find Meter named: in ElectricLoadCenter:Distribution named LOADCENTER

Here's how I'm specifying the objects:

Which version of EnergyPlus are you using?

This part of the severe error makes it sound like EnergyPlus is expecting one of your blank input fields to be a meter name: Did not find Meter named: in ElectricLoadCenter:Distribution named LOADCENTER

Can you paste the definition of the "ResElecTotal" meter too?

Version 9.0. I've added ResElecTotal. Unfortunately it's a Meter:CustomDecrement and I'd have to add a lot of Meter:Customs to show everything. @"Aaron Boranian" it absolutely sounds like that, right?

@Determinant have you tried setting * for the Key Name input fields instead of leaving those blank? That would provide all the cases where each custom meter is measuring energy use.

Just tried it with *, still get same error, but thanks for the idea!
