Eirgrid is how all the electricity in Ireland is distributed across the country. As a key part of the electricity markets, they have a major role in making sure you can turn your light switch on and off effortlessly. In this guide, we'll walk you through how Eirgrid works, what it's for, and how to contact them if you need them!
Eirgrid is the electricity transmission network operator (TNO) in Ireland. It can get a bit confusing, as ESB Networks is the Distribution Network Operator (DNO).
Eirgrid was set up originally in 2000 to enable competition in the Irish power sector. It is regulated by the CRU, the regulatory body for the energy market and water.
Following the deregulation of the market, they took over management of the transmission grid in 2006. Where Eirgrid handles the electricity side, Gas Networks Ireland handles all the gas distribution.
The Eirgrid group is owned by the Irish government. Under ISEM, the Eirgrid Group also owns SONI (System Operator of Northern Ireland) and operates the all-island distribution network.
EirGrid develops and operates the electricity grid for Ireland. The grid safely brings power from generators to the ESB network that supplies every home, farm, community, and business in Ireland.
It also brings power directly to large energy users. They have also worked on projects like the Celtic Interconnector.
Once the energy has been generated at a power plant, for example, its voltage is then increased (so less electricity is lost over distance) and it is moved to a substation along a network managed by the TNO (Transmission Network Operator) - in Ireland, this is Eirgrid.
The transmission network transports the energy from its point of generation along transmission lines, which are much bigger cables and cable towers than the lines outside your house.
Once at the substation, the electricity is then passed through a transformer to reduce the voltage enough to the level required for safe residential use, and sent out on the distribution network (the lines you see on the street outside your house), run by the DNO, this is ESB Networks in Ireland.
You then need to contact one of Ireland’s twelve residential electricity suppliers to manage payment for your access to, and use of, the distribution network.
So in a nutshell, TNOs move energy from points of generation to substations, and DNOs (ESB Networks) move electricity from substations to near your home or other areas where it’s needed.

The Eirgrid dashboard is an online web app known as the 'Eirgrid Smart Grid Dashboard'. The dashboard allows users to see and compare all-island power system statistics and graphs, in one place. We checked it out and discovered several interesting features.
You can see a lot of interesting information regarding the energy market in Ireland through using the Eirgrid dashboard. Here's a list of the most important features:
If you are in or interested in the energy sector, this smart grid dashboard is a great tool as it provides real, up-to-date information about electricity in Ireland.
We also think the renewable energy generation graphs and the CO2 emissions information are helpful to enable the general public to see how they struggle to meet our Paris Agreement targets.

Eirgrid’s responsibilities include managing the power grid, the wholesale electricity market, and maintaining and developing the high voltage (transmission) electricity structure. Finding ways to integrate renewable energy is currently a high priority.
To help Ireland meet its 2030 renewable energy targets, the company is aiming to have the grid ready to carry 70% of Ireland’s electricity from renewable sources. At present, only 36% of your power comes from clean generation, well short of the targets set by the Paris Agreement.
That said, there are also many successes regarding renewable energy so far, specifically:
The challenges integrating renewable resources according to the corporations 'Shaping our electricity future' technical report are:
While we wait for the operator to solve these nationwide challenges, you can do your part by switching to a 100% renewable energy provider. In the table below, you can see how much of your supplier's electricity comes from renewable sources.
| Supplier | Percentage |
|---|---|
| Ecopower* | 100% |
| Energia | 100% |
| Flogas | 100% |
| Pinergy | 100% |
| SSE Airtricity | 100% |
| Electric Ireland | 80.72% |
| Community Power* | 42.93% |
| Bord Gáis Energy | 30.38% |
| PrePayPower | 25.31% |
| Glowpower | 24.27% |
| Waterpower* | 24.27% |
| Yuno Energy | 21.3% |

So, as the TNO for Ireland, Eirgrid must be the people to call when there is a power outage, right? Well, yes and no.
The operator DOES schedule planned outages for maintenance, updating electricity-generation facilities, adding and removing transmission lines, and resolving any other underlying issues. These outages are generally organised to cause the least disruption possible, although it’s impossible to avoid altogether.
Customers in areas affected are always notified ahead of time. So for queries related to planned outages, yes, Eirgrid is the point of contact.
For unplanned power outages, it’s generally not because of an issue with Eirgrid’s transmission network and is much more likely that the fault lies with the distribution grid. The distribution network is managed by ESB Networks and you can look at the power check website to see if there is any information about outages in your area, or contact them directly.
Fallen Live WiresIf you see any fallen electricity wires, never touch or approach them as they are extremely dangerous. Please call emergency services straight away on 999, 112, or 1850 372 999.

Eirgrid plc has a set of rules they need to follow, as does anyone involved in the electricity industry in Ireland, this is known as the Grid Code.
The Eirgrid Grid Code is always evolving and indicates the rules and guidelines which need to be followed for the maintenance, operation, and development of any electricity grid user.
On the website Glassdoor, Eirgrid receives a rating of 3 out of 5 stars as an employer.
Some of the positive comments left by employees are as follows:
Lovely people, nice to work and interesting work.
Great people within the company.
Some of the negative reviews left are regarding that it is state-owned and has few middle management progression possibilities.
Most Eirgrid jobs are for engineers and business graduates, although there are some financial controller and administrative positions available as well. Jobs advertised are evenly split between contract, permanent, and temporary positions.
So, we know that we need electricity for just about everything in our day-to-day lives, but how did we get to this point? The beginnings of ESB Networks, Eirgrid, and the Irish electricity grid as we know it today, can be traced back to 1927.
After the successful Shannon Scheme (a hydroelectric dam) at Ardnacrusha, the ESB was formed to manage the electricity supply. At that time, incredibly, Ardnacrusha supplied 80% of Ireland’s electricity, yet nowadays only accounts for 2% of the amount needed. Boosted by the success of Ardnacrusha, the government then built more hydropower plants, harnessing 75% of Ireland’s inland water potential for electricity supply, by 1949.
By the early 2000s, great strides had been made in power generation and transmission. All areas of Ireland (apart from some small islands which still depend on generators) are now connected to the grid, several power stations have been constructed, and 60 wind farms are connected. Renewable energy technology is also being integrated all the time, following a €22 billion investment programme that began in 2008 and continues today.
It is into this developed system that Eirgrid began operations as the TNO for Ireland in 2006.
