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.
