What is a generating CMU?
i) A Generating CMU – This can be existing or new plant or storage equipment capable of exporting electricity to the transmission system or distribution network via a single half-hourly meter capable of independent control.
What is a CMU & how does it work?
A CMU is a unit of electricity generation capacity or electricity demand reduction that can then be put forward in a future Capacity Market auction. In this respect it is the product that forms the capacity to be purchased in the capacity market.
What is the minimum capacity of a CMU?
A CMU must have a minimum capacity of 2MW. Limited aggregation is permitted with sub-units (Components) aggregated behind a single (for Generating) or multiple (for DSR) half hourly meters.
What is a capacity committed CMU?
Capacity Committed CMU – A Prequalified CMU that has been entered into a specific auction and has not been withdrawn from the auction before the auction has cleared. The relevant Applicant (i.e. asset owner) is issued with a Capacity Agreement for that CMU making the Applicant a Capacity Provider.
Can separate metered units be aggregated to form one CMU?
Separately metered units of over 2MW cannot be aggregated to form one CMU as the purpose of aggregation is to permit access to the capacity market of smaller Components.
How does the energy management system work?
The energy management system handles the controls and coordination of ESS dispatch activity. The EMS communicates directly with the PCS and BMS to provide high-level coordination of the various components on-site, often by referencing external data points.
