What are Electricity DUoS Codes (DG Codes)?

DUoS, stands for Distribution Use of System and forms the basis of what ESB Networks charges electricity suppliers for the use of the local electricity distribution system. The distribution system consists of power lines, transformers, and sub-stations that bring electricity from electricity generation plants to the end user. The infrastructure needs to be built and maintained by ESB Networks.

Your electricity supplier must pass DUoS costs onto you, whether as part of a bundled price plan or separately, if you are billed for energy and non-energy charges as individual line items on your bill. The cost of the electricity grid is recouped on your electricity bill. Your electricity supplier is effectively a collection agent and passes the money to ESB Networks.

The amount of DUoS that ESB Networks charges electricity suppliers for each customer depends on the DUoS Group for the meter being supplied. This, in turn, is based on several factors, including the connection voltage, the type of meter installed, and whether electricity is exported.

Understanding your DG code and MCC code is just the start of your journey. You must then pick a supplier and make sure that you are not overpaying for electricity. That's where Utilityfair's energy experts can help.

What are Electricity MCC Codes (Meter Configuration Codes)?

MCC stands for Meter Configuration Code. It is a code that describes the type of electricity meter installed and the time-of-use tariff available. For example, the simplest form of meter is a 24-hour meter where the unit price is the same regardless of when energy is used. The next step up is a nightsaver meter, which records daytime usage (8am to 11pm) and nighttime usage (11pm to 8am) separately. Nighttime electricity rates are lower, but this is compensated for with a higher daytime electricity rate. For larger energy users, quarter-hour meters are installed. Quarter-hour electricity meters transmit usage to ESB in 15-minute intervals. These larger meters often have summer rates, winter rates, peak rates, weekend rates and night rates. The table below shows all of the MCC codes.
