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.
Acting responsibly in all aspects of our business is one of our key priorities.
The project aims to review the current ESB Networks planning and security of supply standard and update and evolve these standards to ensure that they facilitate the objectives of the ESB Networks Innovation Strategy. These novel standards will take account of the requirements of binding National and EU Energy Directives and Network Codes, whilst cost effectively maintaining a safe, secure and reliable distribution system. These novel standards will facilitate the introduction of non secured access for distributed generators and non wires alternative solutions.
The attached document outlines the key performance criteria on which ESB Networks reports on an annual basis.

Decarbonisation of the electrical network will see a significant impact on the Low Voltage (LV) network with the increasing integration of Low Carbon Technologies (LCTs) such as heat pumps, solar PV and Electric Vehicles. The effect on the LV network as a consequence of the integration of these new technologies is not yet fully understood. To gain valuable knowledge of these technologies, ESB Networks are trialling a number of different innovative monitoring devices to fully understand what is required to effectively monitor the LV network.

As Ireland works meet its renewable energy targets, distributed generation assets will increasingly play a role in contributing to the national power supply. In order to ensure the security and sustainability of the system, EirGrid launched the DS3 Programme. As the DSO, ESB Networks is working with the TSO to deliver the DS3 through a number of programmes designed to deliver innovative technologies, processes and standards to ensure that non-synchronous generation from renewables such as wind, deliver maximum benefit and minimal disruption to the network and our customers.
This project is a key enabler to ensure distributed generators are able to withstand system frequency changes driven by the increased amount of renewable generation connected to the network. In order to operate the power system with up to 75% of the instantaneous power coming from non-synchronous sources new Rate of Change of Frequency (RoCoF) relay settings are required for distributed generators. Failure to achieve this would have resulted in the ratio of non-synchronous generation on the system being capped at 60%, as opposed to the target of 75%.

The provision of DS3 system services from Distribution Energy Resources (DER) ensures frequency and voltage stability on the transmission network. These system services or flexibility products are typically provided by existing generation and demand customers who are connected to the distribution network. This project entailed necessary learning, procedures, modelling and testing to enable the advance technical assessment by ESB Networks to detect any adverse impacts on distribution network planning or operations from the provision of DS3 System Services.

As extreme weather events and cybersecurity threats become more frequent, and our economy electrifies, ESB Networks will need to build network resilience to mitigate disruption, ensure the security of supply.
The aim of this H2020 project was to design, develop and validate, an adaptable security framework on small scale field trials. This framework showed how risks of cyber threats and attacks were reduced when metering systems are deployed as part of grid applications. The SUCCESS project developed three use cases which incorporated security, resilience, survivability and privacy. The Irish trial site performed the use case emulating the mass attack on EV chargers.
