We are ESB Networks. We ensure that electricity gets to the homes and businesses of our 2.3 million electricity customers, safely and efficiently. We have invested over €6bn in the electricity network over the last 10 years to ensure that it is reliable and enables communities and businesses in Ireland to grow and develop.
We provide a wide range of services to our customers, all of whom need to be registered with an electricity supplier. Each year we carry out over 9 million meter readings and provide these to your supplier in order to ensure you receive correct billing. We also deliver a range of technical services such as restoring supply when network faults occur, for example due to storms. Other services, some of which are chargeable, include undertaking line alterations at the customer’s request and carrying out service alterations requested via suppliers.
Your safety is our priority. Electricity is a powerful energy source but it can be dangerous. Always follow our safety guidelines. To ensure you stay safe, stay clear of overhead, underground and fallen electricity wires, always look out for electricity wires when you are outside . ‘Stay safe, stay clear’. For emergencies call 1850 372 999.

Distribution Code defines the technical aspects of the working relationships between the DSO and all other users of the Distribution System. It aims to ensure an efficient, co-ordinated and economical system for electricity distribution. The Distribution Code was first approved by the Commission for Energy Regulation (CER) in March 2000. Any modifications or updates to this code must be approved by this Commission. More detail is available in the Distribution Code Review Panel Constitution and Rules.

CRU has approved Modification No. 36 of the Distribution Code. The requirements stated under DCC11 are driven largely by the combined effect that large penetration of Non-Synchronous generation on the operation of the Transmission System. To date, this cohort of generation has comprised, almost exclusively of wind generation. It is now apparent that other forms of generation [most notably PV], which have an invertor between the primary source and the Connection Point, present the same technical challenges to System Operation. It is logical therefore that the same technical requirements should apply to them.
This approach is also consistent with that which will be taken upon adoption of the European Network Codes, most notably the Requirements for Generation [RfG], wherein the document structure is divided between Synchronous Generators and what are termed Power Park Modules.
Separately, the total quantum of generation connecting to the system has reached levels at which the quantum of un-controlled real power from distribution connected generation poses a threat to the stability of the power system. For that reason and for the reasons stated above with regard to the increase in solar generation connections, EirGrid deem necessary to make more of the PPM fleet MW controllable.
