The Reference Scenario includes an additional 13 GW of offshore wind capacity for the NSCOGI region between 2020 and 2030. A sensitivity was studied significantly increasing the amount of installed offshore wind capacity (called “RES+”) to establish whether the benefit of meshing would increase with increasing offshore wind volumes. This was considered the most important parameter to investigate due to the probable impact increasing offshore wind capacity is expected to have on the offshore grid design and to allow comparability with other offshore grid or RES integration studies (e.g. [12]; [13]; [17];[18];[21]; [23]) that consider significantly higher offshore development than reflected in the Reference Scenario. It was also expected that higher volumes of offshore RES would reveal potential benefits of an integrated offshore grid in a more illustrative way. The RES+ sensitivity figures for offshore RES, presented in 'Table 3-2, were based on the most ‘green’ national scenarios available to TSOs in early 2012, see also list of Page 26 of 142
References. All other generation / load data remains the same as the Reference Scenario. It should be noted that the figures for offshore RES in this scenario were not necessarily validated by Government authorities and may therefore not be consistent with published Government projections. Other sensitivity analyses, like a 'Merit order Shift' and 'Smart Dimensioning of Offshore Wind Farm connections' were identified as appropriate sensitivity analyses to be conducted in the next stage of NSCOGI.
