Glossary Term: Balancing Mechanism Unit
Balancing Mechanism (BM) Units are used as units of trade within the Balancing Mechanism. Each BM Unit accounts for a collection of plant and/or apparatus, and is considered the smallest grouping that can be independently controlled. As a result, most BM Units contain either a generating unit or a collection of consumption meters. Any energy produced or consumed by the contents of a BM Unit is accredited to that BM Unit.
BM Units can be classed as either Primary or Secondary BM Units. There are several types of BM Unit, each representing different aspects of the system. They are: Directly Connected; Embedded; Interconnector; Supplier; Secondary; and Miscellaneous.
