In order to work on the NTS, it is sometimes necessary to take an outage of a part of the network or reduce the flexibility available (e.g. where steady flows may be required). This may affect one or more parties connected to the network including:
We are also incentivised on some aspects of our maintenance activities.
Types of maintenance
Customers may be affected as a result of:
pipeline and defect inspections;
emergencies and faults; or
work to facilitate investment in the network which may be as a result of a new connection or capacity requirement (common maintenance types).
We aim to minimise the impact of our maintenance on customers by being transparent about what we do, aligning our work with their outages as appropriate, and facilitating customer needs for flexibility.
Each year, we ask when our customers' outages will take place, so we can align works. If your outages move, please email us ([email protected]) as early as possible, so we can consider if we can realign our works to reduce impact.
Sometimes standard maintenance approaches may not be optimal for our customers. Where this is the case the Minor Works Agreement can enable parties to agree different maintenance approaches through a bilateral contract with directly connected customers. Customers can pay the incremental costs of working flexibly outside normal working practices where we are able to accommodate these requests. For example:
Customer-initiated requests for us to change our planned maintenance to a non-standard arrangement, such as requesting planned maintenance during non-standard hours (e.g., weekend or bank holiday).
Customer-initiated requests for NGG work, including the isolation of their supply to facilitate the customer's works.
