When to use MMBTU or MMBtu?

For EMIR reporting, MMBTU is the correct format.

For REMIT reporting, MMBtu is the correct format.

If a submission is made in CpML with MMBTU destined for REMIT, the CMS would transform the value accordingly when creating the T1 file (in MMBtu). If they send in T1 files directly, the submission would need MMBtu already in the input document.

Only when submitting a CpML the CMS will translate the value from "MMBTU" to "MMBtu", however if not (i.e. submitting in Table 1 files directly) the format of "MMBtu" should be used.
