System Operator Companion Guide for Commissioning Generation

We have published a Companion Guide for Commissioning Generation to aid existing and new Asset Owners alike  understand the process they will need to follow with the System Operator to enable the successful development and agreement of a commissioning plan for generation greater than 1 MW in size.

The Companion Guide provides guidance on the typical activities that need to be considered when planning for, commissioning and testing or decommissioning generation, and the minimum lead times for critical tasks.  This guideline along with other key documents are listed in the table below for quick reference.
