Availability Heatmap

About

The Availability Heatmap gives an overview of where units have and haven't been available over time and this can be used to see who was available in a given week, or it can be used to get a more strategic view of the market.

Within this screen it is possible to Hide Fully Empty Rows to reduce the amount of detail being shown and it is possible to filter for one or a combination of different filter types.

For instance, the following screen shows the levels of availability in the market for coal stations through from 2014 to November 2019:

The zones can be seen in the following map:

This shows where units were in outage and also shows plant closures at Longannet for instance and the major change in approach at Eggborough over the period.

Included Data

The data on this heatmap is the Max Export Limit availability data (the maximum level at which the BM Unit may be exporting to the GB Transmission System at the Grid Supply Point) divided by the Generation Capacity (the output of the unit at 100% availability).
