The first step in connecting a new demand customer (large user of power) or a generator to the system is to assess if the facility would be best suited for connection to the Transmission or Distribution System.
For projects with a total demand of less than 20MW (megawatts) or MVA at a single location, a Distribution connection should be investigated first with ESB Networks and more information is available on their website. If the total demand is more than that figure, then a Transmission connection should be investigated with EirGrid and more information on applying to EirGrid is available by clicking below.
Under 40 MW total export capacity at a single location should initially apply to ESB Networks for a distribution connection. Find more information here.
Over 40 MW total export capacity at a single location should initially apply to EirGrid for a transmission connection.
All parties applying to connect to the Transmission System must submit a formal application to EirGrid as the Transmission System Operator (TSO). Applications are processed through the Connection Offer Process as approved by the Commission for Energy Regulation (CER). This process is in place to ensure fairness, provide transparency and facilitate timely delivery of Connection Offers.
Electricity suppliers sell electricity to electricity customers (domestic, commercial, or industrial) utilising the electricity system which is operated by EirGrid at transmission level and by ESB Networks at distribution level.

Demand Side Management involves users of electricity having the capability to change their usage from their normal or current consumption patterns. It can provide significant benefits for customers in terms of reduced bills and gives them greater control over the energy they use and produce. It can help EirGrid in managing the power system efficiently.
