Starts Chart

About

The Starts chart plots levels of starts for groups of units across the market over a defined period of time. This shows which units have had to see the most starts over a period.

For a single filter type this will allow you to see which units are frequently coming online and which units are avoiding starts where possible.

Included Data

The starts are counted based upon each half-hour period in which the balancing adjusted generation (levels of post-balancing generation after National Grid has adjusted generation within gate closure) is positive in a half hour period, but zero or negative in the period before.

This indicates how often units are coming on and off, but it should be noted that these values are calculated from half-hourly not by minute data so fast units such as pumped storage units may have more starts than those indicated.

Data Service

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