ESB Networks Ireland: Services, Faults & Contact

ESB logo

The ESB (Electricity Supply Board) was set up in 1927 as an entirely state-owned utility provider, to control and develop the national electricity grid in Ireland.

What is ESB?

Over the years, ESB has pioneered electricity production, transmission and distribution. Today, the company is a semi-state owned body composed of several legally-partitioned companies that deal with electricity. It's also dipping its toes into the telecoms market with dark fibre network construction and maintenance.

What is dark fibre?Dark fibre is optic fibre that is not in use, as opposed to “lit” fibre which is being used. It came about as extra fibre was laid down while installing optic fibre networks in order to cater for increased demand in the future. Companies can rent this dark fibre to create their own independent networks, rather than depend on the supplied bandwidth.

Among ESB's companies are ESB Networks Limited, which manages the electricity distribution networks, and Electric Ireland, which is the retail arm of ESB that supplies electricity directly to customers.

Following the call for deregulation of the Irish electricity market, ESB was required to reduce its market share to 60% before rebranding and being allowed to reenter the market as a competitor under the Electric Ireland branch.

ESB's current mission is to transition to low-carbon energy and increase the focus on renewables, but will it be enough to satisfy Ireland’s commitment to reducing its carbon footprint as part of the Paris Agreement? Only time will tell.

As part of ESB's strategy, the company has analysed the sources of Ireland’s greenhouse gas emissions. For example, fossil fuels produce around 15% of our greenhouse gas emissions, and when it comes to cars, petroleum also emits a similar amount of carbon dioxide as petrol.

However, yearly emissions from petrol are less than diesel on average, as overall mileage is reduced with petrol. ESB is focusing on not only reducing emissions, but also increasing Ireland’s green energy capacity by investing in renewable and sustainable energy sources.

As such, ESB is investigating converting energy sources dependent on fossil fuels, such as the largest power plant in Ireland, Moneypoint - which runs on coal - to more environmentally friendly options. ESB had previously broached converting Moneypoint to a nuclear station, but strong opposition to nuclear stations (stemming from the long shadow cast by Chernobyl and the ongoing calls to close down the UK Sellafield nuclear power station) make this unlikely.

Current renewable energy sources being invested in by ESB to integrate into Ireland’s electricity infrastructure include wind energy projects such as Coillte(whose wind farms are now owned by Greencoat Renewables) and Oweninny Wind Farm, in addition to four other UK wind farms. Solar energy for household “self” consumption is also being encouraged, with ESB supplying solar panels and the SEAI providing grants of up to €3,800 for home installation.

Who is ESB Networks?

ESB Networks owns and operates the electricity distribution network in the Republic of Ireland. It is also responsible for installing, maintaining, and reading electricity meters. ESB Networks serves more than 2.3 million customers across the country.

As the distribution network owner (DNO) ESB Networks manages the network of towers and cables that transports low-voltage electricity to homes and businesses from the electricity transmission network, which is run by Eirgrid.

ESB Faults & Power Check

Overhead power lines

ESB Power Check is a handy website tool where you can see any ESB faults, the exact location, how many customers have been affected, and whether the interruptions were scheduled or unplanned. You can report an ESB fault online or by calling 1850 372 999.

Before calling, ESB advises you check out whether your neighbours have power or if the streetlights are on. If the streetlights are not on and/or your neighbours are without power, you should call to report the ESB fault. If this is not the case, then check your fuse box to see whether a switch has tripped or a fuse has blown.

If you can’t see anything amiss with your fuse box, then call the service interruption number above anyway, as it’s possible that the ESB Network’s main fuse for your home may be the culprit. Quote your Meter Point Reference Number (MPRN) when you call, as this will help ESB determine your exact location.

Be aware that you may be liable for a callout fee of up to €136 if the issue ends up being your appliances or your fuse box, and not an ESB related issue.

ESB Power Outages

Although ESB makes every effort to keep the electricity distribution system up and running, storms and other natural disasters can, and will occasionally bring down some lines or cause other damage, disrupting your electricity supply.

There are also planned outages in order to carry out routine maintenance and system updates. When an outage is scheduled, you will be notified by post at least two working days in advance.

Whether an outage is planned or not, it’s always best to be prepared for one, rather than stumbling around in the dark barking your shins on your furniture. We’d advise having a stash of batteries and a torch in an easily accessible place so you can light your way, and also check out your fusebox in order to see whether it’s a supply issue or a fuse issue.

If you should see any downed or damaged lines please call ESB immediately on: 1850 372 999. Under no circumstances should you approach, touch, or attempt to move the line.

We also recommend writing down your MPRN , which you can find on your electricity bill, and keeping it either with your torch and batteries, sticking it onto your fuse box, or saving it to your phone. Knowing your MPRN will help ESB operators identify and locate the issue faster.

Try and keep your phone charged as you should be able to find out information about how long the outage will last on ESB’s Twitter page, the Power Check page, or the Power Check app (Android & iOS). In a pinch, you can use your car to charge your phone, or alternatively invest a few quid in a power bank (a portable external battery for charging).

ESB advise that you keep your fridge and freezer closed up tight as the food inside can stay cool for up to 24 hours and most outages will only last 8 hours maximum.

Vulnerable Customers & Customers dependent on electricity for medical reasons:Please ensure you have registered with ESB, so that you can receive priority assistance in the event of an outage. For more information on registering and services, please check out our special services page(coming soon!).

ESB Connection Services

Do you need a new ESB connection for a domestic property or a small farm? We break down how to get one in four simple steps!

  1. Fill out and submit an ESB new connection application on the ESB website. It will take 10 to 15 minutes to complete. You will be prompted to create an ESB account and need to provide the following information in the appliction:
    • Your MPRN. Your builder or developer should be able to provide this.
    • Digital copies of your site plan and ordinance survey map. The location should be clearly marked in red.
    • Accurate coordinates to identify the location.
    • Details about the load and connection capacity.
  2. Register with an electricity supplier. Before choosing just any electricity supplier, we recommend that you do a bit of research to find the best rates for your home. For a free comparison, give us a call on 1800 816 036 or check out the following guides for help deciding:
  3. Get your connection turned on. Your chosen supplier will contact ESB to reqest this. For your connection to be turned on, the registered electrical contractor for the building must send a certificate to his/her regulatory body. This is to confirm that all works have been completed to meet ESB Networks' standards.
  4. Go live with the connection. The builder’s electrician will switch on the electricity for your home.

How long does it take to get an ESB connection?

Once you have applied for a new ESB connection, you should receive a quote within 15 days. If you accept the quote, ESB Networks will aim to complete the new connection within 60 business days. Most ESB new connections are completed within just 10 working days.

ESB Meter Readings

electricity meter

As the branch of ESB tasked with running and maintaining electric utilities, ESB Networks also performs all electricity meter readings. If you are out and miss an ESB meter reading, or if you have received an estimated bill, we always recommend you submit your own ESB meter readings. Underestimated bills can lead to nasty shocks later, and overestimated bills should mean the additional cost you have been charged will be used against the next bill or refunded to you.

If you’re not sure how to read your meter, check out our handy meter reading guide. You can then submit your ESB meter reading online. If you have one of the more modern smart meters, your bills should always be accurate and there is no need to submit additional readings - one more thing ticked off your to-do list.

ESB Top Up

ESB top-up is now managed through Electric Ireland’s top up system, where depending on whether you have a smart pay as you go (SPAYG) meter or a traditional electricity PAYG meter, Electric Ireland provides a wealth of options, such as at Payzones, via SMS, online and via the app.

Electric Ireland provides traditionally billed options, PAYG options, and smart pay-as-you-go options using its cutting-edge in-home monitor and smart meter. For more information on topping up with Electric Ireland, view the top up section in our Electric Ireland guide.
