The North Seas Countries' Offshore Grid Initiative - Initial ... - Benelux

2 Methodology Overview
2.1 Overview
The process adopted by Working Group 1 of NSCOGI to develop grid designs is essentially
the same as that used by TSOs to plan their own internal grid enhancements, though
differing in some of the details of the various activities.
The general procedure from Figure 7-1in Appendix A 1is divided into a number of logical
steps as illustrated in Figure 2-1 below. Each activity enhances the knowledge about
investment requirements and adds to the refinement of the grid designs. Although the
process flows sequentially through each activity, there are checks at each stage built into
the process that allow for a step back to the previous activity with modified inputs and
assumptions to improve the quality of the outputs.
It is important to state that for this study there was only a single run through the overall
process – although comprising several micro-iterations between the activities. Due to the
nature of the study, dynamic investigations have not been executed. It is therefore
possible that the maps and figures would change when continuing with additional
iterations. The addition of a small icon on all of the maps included in this report serves as
a reminder of this fact.
While the Reference scenario included several micro-iterations, the RES+ sensitivity
described later in the report, did not. A reminder of this fact is made by the use of
another icon on the respective maps, preventing the reader from making a direct
comparison of the results from the sensitivity analysis with those from the scenario itself.
