Run Hours

About

The Run Hours chart plots levels of run hours for groups of units across the market over a period of time. This shows which units have achieved the most consistent levels of run overs over a period.

This will give you total levels of run hours by filter, say total run hours at coal stations in the period, and across a filter a comparison can be made of all units.

Included Data

The run hours calculation used counts each half-hourly period in which generation exceeds zero and counts this as 0.5 hours of running. The generation measure used is the minimum of the Max Export Limit (the maximum level at which the BM Unit may be exporting to the GB Transmission System at the Grid Supply Point) and the balancing adjusted generation (levels of post-balancing generation after National Grid has adjusted generation within gate closure).

This gives a level of run hours that accounts for any outages or trips that prevent actually delivering as intended.

Data Service

The Run Hours data can be extracted from the API to get the number of run hours by unit within a grouping over a period of time. The parameters used as follows:
