Following offer acceptance a project design will commence. In the case of GPA applications the design will not start until all offers in a group or a subgroup have been accepted. Once all offers in the cluster are accepted DSO approves the project for construction. At this stage the project details are provided to our High Voltage & Delivery & Contracts Section (HV D&C) which in turn will contact the Customer to initiate the design process which covers elements such as achieving any planning permissions and clearing of wayleaves.

Throughout the design phase regular communications will be held with the Customer to progress and finalise the connection.

Generally, at offer acceptance the Customer will be required to provide:

  • The correctly executed Connection Agreement (both customer and return copies)
  • The First Stage Payment
  • The correctly executed Declaration of Independence (only applicable to wind generators less than 5 MW)
  • Generators with an MEC of greater than 5MW will need to provide evidence of current TUoS Agreement with the TSO. This Agreement sets out the terms and conditions upon which the TSO and the generator have agreed in relation to the use by the Generator of the Transmission System. For more information on the TUoS agreement please contact EirGrid directly on 353 1 702 6642 or by email


For the actual items to be returned with the correctly executed connection offer documentation please see your connection offer as these may vary.

Once the necessary conditions for acceptance set out in the Quotation Letter have been fulfilled by the Customer, DSO will countersign both the customer and return Connection Agreements.  The customer copy of the Connection Agreement is returned to the customer with  a letter of acknowledgment to confirm that there is a Connection Agreement in place.

The most important thing to consider is if the electricity supply capacity is sufficient for your needs. Every building now has a registered supply capacity called a Maximum Import Capacity (MIC). MIC is the contracted electricity capacity for your premises based on information your developer has provided to us.  It is important to establish the current MIC of the premises. In most cases the MIC is displayed on the Electricity Supplier's bill.  

You should then discuss your present and future electricity requirements with an electrical contractor or engineer. Remember to take into account all business equipment and the building's heating and cooling needs. If the current MIC is incorrect for your requirements, contact us on 1850 372 757 or +353 21 2386555 to discuss. Where possible your MIC should reflect your actual requirements If your MIC level is higher than you need, you will incur unnecessary charges.


The Connection offers that are issued to Non GPA Customers are valid for three months. If not accepted within a three month period the offer will lapse and the relevant New Generator Connection Application (NC5) (PDF | 737 KB) or New Generator Connection Application (NC5A) (PDF | 548 KB) application will be removed from the generator applications queue. In addition, any paper applications will be destroyed.


The validity period for connection offers that are issued to GPA Customers is set out in the relevant CER directions. For Gate 2&3 the offer acceptance period was 50 business days. If not accepted within this period of time the offers will lapse and the relevant New Generator Connection Application (NC5) (PDF | 737 KB) or New Generator Connection Application (NC5A) (PDF | 548 KB) will be removed from the queue. In addition any paper applications will be destroyed.

The Connection Offer is issued in current monies. This means that the CER approved Standard Charges are applied as per the year when the offer is issued. The connection charge is then adjusted by indexation (ie: Consumer Price Index (CPI) / Harmonised Index of Consumer Prices (HICP))  as outlined in the Quotation Letter  from the date of offer issue in respect of subsequent stage payment requests.

Please note if there are any Modifications issued to the Customer, the modified offer will issue using approved charges from the year of the original offer.Consequently indexation will still be applied on the basis of the original Connection Offer issue date.

Yes, as defined in the CER decision paper, customers who have already received offers or with connection agreements in place are allowed to request to move from the bonding requirements in the existing offers to revised bonding requirements as set out in CER/09/138. This specific option will be advised to customers following receipt of their formal request.

Please note the Customer is required to submit a formal request to ESB Networks DAC. on the company's official letterhead signed by a Director/Secretary.

As specified in the quotation letter, a Customer / Generator with an MEC greater than 5 MW and who has not put a bond in place, must provide a capacity bond at the Third Stage Payment, before Commissioning and Energisation or two [2] years from the start of the construction of the Shallow Connection Works whichever is the earlier provided always that the Customer who does not post the necessary bond will not be Energised. Please see our General Conditions (PDF | 340 KB)Schedule 2A for a sample of the Capacity Bond.

If the Customer is unable to obtain a Capacity Bond then following a formal request from the Customer, DSO will consider on a case by case basis whether a Letter of Credit/ Bank Draft for the same amount could be provided instead.

Call us on 1850 372 757 or +353 21 2386555, or email, and we will tell you the status of the application and if there's anything holding it up.
