I get the following warning:

The following Report Variables were requested but not generated -- check.rdd file
**   ~~~   ** Either the IDF did not contain these elements, the variable name is misspelled,
**   ~~~   ** or the requested variable is an advanced output which requires Output:Diagnostics, DisplayAdvancedReportVariables;   
************* Key=*, VarName=ELECTRIC STORAGE DEGRADATION FRACTION, Frequency=TimeStep
************* Key=*, VarName=ELECTRIC STORAGE CHARGE FRACTION, Frequency=TimeStep   
************* Key=*, VarName=ELECTRIC STORAGE OPERATING MODE INDEX, Frequency=TimeStep
************* Key=*, VarName=ELECTRIC STORAGE BATTERY CHARGE STATE, Frequency=TimeStep
************* Key=*, VarName=ELECTRIC STORAGE CHARGE POWER, Frequency=TimeStep   
************* Key=*, VarName=ELECTRIC STORAGE CHARGE ENERGY, Frequency=TimeStep
************* Key=*, VarName=ELECTRIC STORAGE DISCHARGE POWER, Frequency=TimeStep   
************* Key=*, VarName=ELECTRIC STORAGE DISCHARGE ENERGY, Frequency=TimeStep
************* Key=*, VarName=ELECTRIC STORAGE THERMAL LOSS ENERGY, Frequency=TimeStep

I have defined a battery (as in the picture below) and compared with the example file ShopWithPVandBattery.idf. I wonder why I can not access these Outputs defined under "ElectricLoadCenter:Storage:Battery" in InputOutputReference image description

ElectricLoadCenter:Distribution looks like this image description

Hi,

Double check that you have

Output : Diagnostics, DisplayAdvancedReportVariables;

in your *.idf.

If that doesn't work, open either eplusout.mdd or eplusout.rdd (from the outputs folder) to see how the output variable is defined.

Thanks for the suggestions, I forgot to mention that I had turned on

Output : Diagnostics, DisplayAdvancedReportVariables

The term "ELECTRIC STORAGE" can not be found in either the MDD or RDD file (did a search that was not case sensitive).

Is the object Lead acid batteries included in the ElectricLoadCenter:Distribution module?

Thanks, I had overlooked it. I have it included now (I have added the picture of my ElectricLoadCenter:Distribution above), but the problem is still not solved. The error message is still the same.

The report variables you show are only used with a buss type that includes storage. The buss types ending with the word Storage will use those report variables.

ElectricLoadCenter:Distribution,

  A6,  \field Electrical Buss Type
   \type choice
   \key AlternatingCurrent
   \key AlternatingCurrentWithStorage
   \key DirectCurrentWithInverter
   \key DirectCurrentWithInverterDCStorage
   \key DirectCurrentWithInverterACStorage
   \default AlternatingCurrent
