Flexibility Map

Network Flexibility Map

This mapping tool has been developed to display the current and potential future flexibility needs across NGED’s network area. For each geographic area where a potential demand constraint has been identified, an availability window for generation turn-up or demand turn down has been published.

MW Service Availability Window

The maximum timing and duration of flexibility required to resolve a particular constraint. Flexibility may be required in these months at the designated times of day, up the MW level published. An estimated monthly utilisation, in MWh, is also published.

Service Overview

National Grid defines network flexibility services under three products:

Scheduled Utilisation – Settlement Periods - The Scheduled Utilisation service is used to manage peak demand loading on the network and pre-emptively reduce network loading. Comprises of a higher availability payment and lower utilisation payment.

Scheduled Availability, Operational Utilisation - Day Ahead - The Scheduled Availability, Operational Utilisation service has been developed to support the network in the event of specific fault conditions, often during maintenance work. Comprises of a low availability payment and higher utilisation payment.

Operational Utilisation – 15min - The Operational Utilisation service is intended to help with restoration following rare fault conditions. Comprises of a no availability payment and premium utilisation payment.
