Information Gathering Request: Indication of Interest for High-Voltage Connections (NGET Gate 2 Phase 2 Demand customers)

This information gathering request is strictly limited to directly connected demand customers (i.e. demand-only customers as opposed to BESS) that meet both of the following criteria: 

• are within the NGET region and; 
• have a Gate 2 Phase 2 project in the G2TWQ offer process (projects expected to connect after 2031).  

This request does not affect any existing Phase 1 offers or agreements by NGET, as these customers are already at an advanced stage. Nonetheless we will consider whether HV opportunities may be applicable to other cohorts, including Phase 1, and we will update customers as the position develops.  

Should a demand customer in Scotland wish to connect at high voltage, they should follow the existing connection process. No expression of interest is required.

The process will follow these steps: 

• 22 May 2026: Information gathering request opens; 
• 22 May- 15 June 2026: This is the principal window in the G2TWQ process for customers to express their interest in a HV connection. If we do not receive a response now, it will likely limit your ability to be considered for a HV connection at a future date; 
• 5pm on 15 June 2026: Information gathering request closes; 
• 16 June- 30 June: NESO reviews the responses and shares information with NGET; and 
• from 1 July 2026- NGET Phase 2 studies begin. 

After the response window closes, NESO and NGET will proceed on the basis of the information submitted.  

Under the applicable code arrangements, NGET will assess applications and determine any connection offer on the basis of the most efficient and economically viable way to deliver the connection. This is intended to ensure that customer requirements are considered at the right stage, while supporting better outcomes for customers and the wider system, and reflects ongoing work by NESO and NGET to listen and respond to customer feedback as the process develops.

No. Customers should note that while they may indicate a preference for a HV connection, a HV connection offer or the specific voltage requested is not guaranteed and will be determined through the completion of HV connection studies by NGET. 

It will also be subject to the applicable regulatory arrangements and any necessary approvals or clarifications*. Where an HV connection offer is offered following completion of studies, that offer will set out the applicable technical, commercial and regulatory terms, including the voltage level determined to be technically and operationally feasible. 

where an HV connection is subsequently offered, customers may be subject to additional securities and fees in line with the applicable connections charging arrangements. 

*Ofgem is currently working with stakeholders to identify if there are any regulatory barriers or clarifications that may need publishing to ensure arrangements are fit for purpose

Where customers indicate, they are minded to pursue a HV connection, this will be explored with all relevant parties. 

Customers should carefully consider whether a HV connection would be suitable. If an HV connection offer is ultimately made and a customer chooses not to accept it, then, as with any Gate 2 Offer in the G2TWQ process, the existing agreements will be given Gate 1 status and a Gate 1 ATV issued. The project would then be required to re‑enter the connections process in line with the applicable connections and gating framework in order to proceed.  

NGET intends to engage with the relevant parties in advance of making any HV offers as we are aware customers will want to consider carefully before making the decision on their connection offer.
