How We Collect and Use Your Personal Data

What Personal Data Do We Use?

We use, or process, a number of different categories of personal data.

These personal data are largely grouped into two types:

Personal Data You Give Us:

This is information about you that you give us when engaging with EirGrid – for example, by filling in forms, responding to questionnaires or by corresponding with us by phone, face-to-face or by e-mail. It also applies to situations where you respond to a public consultation exercise or an information gathering exercise which relates to EirGrid's general business or responsibility for the safe, secure, efficient and reliable operation of the high voltage electricity Transmission System in Ireland.  The information that you give us may include some, or all of the following (depending on the circumstances):

  • current and previous address, occupation, nationality, citizenship, photo or other I.D. confirmation;
  • your property ownership status and information about your property where you have transmission infrastructure on or near your property;

  • records of any consents you have given; and
  • your use of the EirGrid website.

We may record telephone calls you make to us for training or quality purposes.  Where you provide information about others, you must ensure that you have their consent or are otherwise entitled to provide this information to us.

Personal Data We Receive From Other Sources

This is information about you that we receive from other sources such as our business partners (e.g. ESB), or from publicly available sources such as (but not limited to) the Land Registry, death notices and electoral registers.  The information that that we receive from these sources will include some, or all of the following (depending on the circumstances):

  • your name, date of birth, contact details;
  • current and previous address, occupation, nationality, citizenship, photo or other I.D. confirmation;
  • medical data (as it relates to your capacity);
  • your property ownership status and information about your property where you have transmission infrastructure on or near your property; and
  • your views and feedback on EirGrid’s business or role as the electricity transmission system operator. 

The Purpose and Legal Basis for Collecting Your Personal Data

What Do We Use Personal Data For?

Our core business and central focus is the safe, secure, efficient and reliable operation of the high voltage electricity transmission system in Ireland. To this end we use information held about you in the following ways (as applicable):

  • establishing and maintaining records associated with connections to the electricity transmission system;
  • processing applications for proximity payments;
  • to ensure we are engaging with the correct landowner/home-owner/stakeholder;
  • to keep you informed about our activities including the operation of the high voltage electricity transmission system in Ireland;
  • to analyse, assess, maintain, improve and develop the grid infrastructure;
  • to verify the accuracy of the personal data you have provided to us;
  • management of an electricity connection agreement;
  • managing the safe, secure and reliable operation of the electricity transmission system;
  • planning and developing the electricity transmission system;
  • facilitating the reliable operation of the wholesale electricity markets;
  • to meet our obligations to our regulators; and
  • to deal with your enquiries and requests (e.g. complaints handling). 

What are Our Legal Bases for Processing Personal Data?

Data protection laws require that we have a legal basis in order to use your personal data in the manner described in this privacy statement.

We rely on the following legal bases in order to process your personal data:

The processing is necessary for the performance of a task carried out in the public interest or in the exercise of an official authority vested in EirGrid.

Pursuant to the TSO Licence and its legislative functions, EirGrid must operate, maintain and develop a safe secure and reliable electricity transmission system and in doing so is required to process the information about you referred to in this document.

You have given your consent to the processing of your personal data.

We may use your contact details to provide you with certain promotional information about our activities where you have provided your explicit consent for us to do so.  You may withdraw this consent at any time by asking us to stop sending you such promotional information.  Please note that withdrawing your consent will not affect the legality of any processing which took place prior to this withdrawal.

The processing is necessary for the performance of a contract to which the Data Subject is party or in order to take steps at the request of the Data Subject prior to entering into a contract.

Where we enter into a contract with you (for whatever reason), we will need to process certain personal data about you in order to perform our obligations under that contract.

The processing is necessary for compliance with a legal obligation to which EirGrid is subject.

On occasion, we are under a legal obligation to process personal data.  This could be for the prevention of fraud, or in relation to a criminal investigation.

The processing is necessary for the purposes of EirGrid’s legitimate interests.

There may be circumstances, unless the interests and fundamental freedoms of a Data Subject override them, where EirGrid has a legitimate interest in further processing of personal data.  This could include the transfer of personal data between members of the EirGrid Group for internal administrative purposes.

The processing is necessary for the performance of a function conferred on EirGrid by statute.

Regarding Special Categories of personal data, we may sometimes be provided with certain medical information (for example from legal personal representatives) which relates to a Data Subject’s physical or mental capacity. We may need to process this information when carrying out EirGrid’s statutory functions of operating, maintaining and developing a safe secure and reliable electricity transmission system. We only use this information to allow us to ensure we deal with landowners and other stakeholders in an appropriate manner.

How We Store and Secure Personal Data

Any data we collect from you will be stored confidentially and securely with appropriate technical and organisational controls.  EirGrid are committed to ensuring all accesses to, uses of, and processing of EirGrid processed personal data is performed in a secure manner.

How Long is Personal Data Kept for?

We will only retain your personal data for as long as is necessary to fulfil the purposes for which it was collected.  After that, we will delete it.  The retention period may vary depending on the purposes for which the information was collected.

Where a specific legal or regulatory requirement applies to your personal data, we will retain it for the period of time specified in such legal or regulatory requirement. In the absence of a specific legal or regulatory requirement we will retain your personal data for the applicable
statutory limitation period following the end of the matter to which it relates. We may be required to extend the retention period if the data is required in relation to a complaint, investigation, judicial review, claim or litigation.

Please also note that we are sometimes legally obliged to retain original legal documents, such as easements or title deeds, indefinitely.

Details of Third Parties with Whom We Share Personal Data

Whom Do We Share Personal Data With?

We may share your personal data with the EirGrid Group.  This means EirGrid plc, System Operator for Northern Ireland (also known as "SONI"), the Single Electricity Market Operator for the island of Ireland (also known as "SEMO"), EirGrid Interconnector DAC and EirGrid Telecoms DAC.

We will only disclose your personal data:

  • to business partners (e.g. ESB), service providers, consultants, advisers, suppliers and sub-contractors where necessary for the performance of any contract we enter into with them;
  • to third party suppliers and service providers to the extent they assist us with our legal / regulatory obligations or our business operations;
  • to our regulators for the purposes of complying with our operating licence;
  • to law enforcement agencies, our legal advisors, the courts and any other authorised bodies, for the purposes of investigating any actual or suspected criminal activity or other regulatory or legal matters, etc.
  • in the event that we consider selling or buying any business or assets, in which case we may disclose your personal data to any prospective sellers or buyers of such business or assets;
  • in the event of any insolvency or the winding up (e.g. the administration or liquidation) of any member of the EirGrid Group;
  • if we (or substantially all of our assets) are acquired by a third party, or if our functions or powers (or substantially all of them) are transferred to a third party, in which case personal data we hold
    may be transferred to such third party;
  • to protect the rights, property, or safety of us, our staff, our customers, or others. This includes exchanging information with other companies and organisations for the purposes of staff and customer safety, and crime prevention; or
  • if we are under a duty to disclose or share your personal data in order to comply with any legal obligation or regulatory requirements, or otherwise for the prevention or detection of fraud or crime.

Transfers of Your Personal Data Outside the European Economic Area

The personal data that we collect from you may be transferred to, and stored at, a destination outside the European Economic Area (the "EEA"). The EEA includes all EU countries plus Iceland, Liechtenstein and Norway. One example of when we do this is when we use certain third-party cloud storage providers.

When we send personal data outside the EEA, we make sure suitable safeguards are in place (in accordance with European data protection requirements) to protect the data. In all cases these safeguards will be one of the following:

  • Only sending the data to a country that has been approved by the European authorities as having a suitably high standard of data protection laws, “essentially equivalent” to the GDPR.
  • Putting in place a contract with the recipient containing terms approved by the European authorities as providing a suitable level of protection.
  • Only sending the data to an organisation which is a member of a scheme that has been approved by the European authorities as providing a suitable level of protection.

More information on these safeguards can be found on the European Commission's website.

Since the departure of the United Kingdom from the EU (“Brexit”), SONI, as a member organisation of the EirGrid Group based in Northern Ireland, is outside the EEA. This means that data, including personal data, held by the EirGrid Group is being transferred and stored outside the EEA on a regular basis, each time a member of the EirGrid Group transfers or stores personal data with SONI.

Following the European Commission’s adequacy decision of 28 June 2021, the United Kingdom’s data protection laws have been approved as “essentially equivalent” to those that exist in the EU. For this reason, the EirGrid Group can transfer personal data to and from SONI without any additional requirements.

If you have any queries in relation to the UK’s data protection laws or would like to know more about your rights or the complaints process in relation to data protection in the UK, you can visit the website of the Information Commissioner’s Office. Alternatively, you can contact their Northern Ireland office at:
