The Maintenance Days Use Incentive Scheme is a financial incentive which was originally introduced for two years from 01 April 2013. The scheme was renegotiated during 2014/15, with scheme structure and parameters amended to reflect the initial incentive period. The scheme is designed to minimise the impact of our Maintenance on our customers. The maintenance operations within the scope of the incentive are:
- Valves are used to control the flow of gas and isolate pipelines in an emergency. To ensure the safe operation of the system, National Grid maintain key valves on an annual basis where they will need to be opened and closed to ensure operation, requiring a system bypass to maintain supply.
The incentive requires National Grid to optimise its use of Maintenance Days on which supply to individual customers connected to the network is interrupted. This minimises the amount of time in which our customers are affected whilst we are performing this maintenance.
The scheme has a target set at 11 days. If we utilise less days for these operations than the benchmark, we gain tiered payment of each day between £15,000 and £25,000 per day capped at £0.215 million. However if we use more days for these operations than the benchmark we receive a penalty of £20,000 per day with a maximum penalty for the year of £0.5million.
We will publish our performance
each quarter on this incentive, with the first report published in July.
