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.
Whether you are a domestic or a commercial customer, we will provide a new electricity connection that best suits your needs.
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.
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.

Intermittent Faults on Low Voltage (LV) underground networks cause temporary loss of supply to customers. Due to the nature of these intermittent faults they have proved difficult to locate. ESB Networks planned on using the REZAP Vacuum Circuit breaker and BIDOYNG smart fuse, from Kelvatek, to improve LV performance as part of the Smart Grid MV/LV Control Operation trial. This aimed to deliver improved continuity and customer satisfaction.

Sensitive Earth Faults (SEF) are difficult to detect as they have very low fault current values. During SEF operation, the protection device does not attempt to automatically reclose the circuit breaker to test if the fault conditions are still present. Customers remain off supply until the site is visited by ESB Networks staff. The project’s aim was to trial innovative approaches to SEF to improve the continuity of electrical supply to customers.

With the use of data analytics ESB Networks pursued a new avenue in identifying metering anomalies and developing a tool that can identify suspicious readings related to meter interference. The project developed an algorithm that can rank a pool of different meter readings based on statistical probability. ESB Networks revised the initial algorithm to a more complex version that is fine-tuned over time as more data is collected and analysed. The expected roll out of smart meters should lead to an increase in data volume and allow further fine tuning of the algorithm with AI.

Delivering a future-ready network service and ensuring operational excellence requires a deep understanding of where, how, when customers use the network, why faults occur, and having the ability to deploy solutions quickly. Central to these efforts is the empowering employees with the technology necessary to gather, manage and analyse network data.
The safety of over 1,950 Network Technicians and over 1,000 other field staff who travel alone is paramount. In order to reduce the potential vulnerability of our staff working alone, ESB Networks introduced a safety device to provide extra reassurance. This project tested and assessed the suitability and associated integration into our digital system of the V.ALERT lone working device to improve lone working safety in case of an emergency.

Traditionally, large fossil fuel based generation provided flexibility on our systems. New flexibility technologies such as energy storage, vehicle to grid (V2G), web based domestic control systems, Smart Meters, advanced information sensing, advanced data analytics and new supplier business models are now emerging to take the place plant of large fossil fuel generators and decarbonize flexibility.
The aim of the Flexibility on Our Networks roadmap is to understand the impacts and the possibilities provided by the use of flexibility in the overall electrical energy system and also develop systems and processes that cost effectively enable the provision of flexibility from within the distribution network.
Real Value was a H2020 project to investigate the impact of controllable electric heating to provide a more flexible network and a solution to Demand-Side Management (DSM) at Low Voltage (LV) level. This allowed energy users of all kinds to act as “virtual power plants”. The project was completed in collaboration with Glen Dimplex, EirGrid, Intel, SSE, UCD and Oxford University and included physical demonstrations in Ireland, Germany and Latvia where the Smart Electric Thermal Storage (SETS) units were installed into 1,250 homes.

As our customers choose technologies including air source heat pumps (ASHPs), storage heating, private electric vehicles (EVs), electric buses, freight and trains in ever higher numbers, greater demands will be placed on the network.
ESB Networks must innovate in network planning and operation, to meet these new demands, without compromising our customers’ comfort, security or quality of supply, and at an economic cost reflecting our customers’ needs and values.
Central to the electrification of heat and transport is to ensure the Low Voltage (LV) network can support and enable the increasing electrical demands from customers’ low carbon technologies. The project will deliver new and consistent design approaches for new and existing LV networks. This will support the economic integration of customers’ low carbon technologies and distribution energy resources such as electric vehicles, solar PV and heat pumps. This involved robust statistical analysis to derive new metrics, values and design tools for the LV network.
