Siemens submitted contract variations totalling approximately €0.8 million, the majority relating to reprogramming and schedule changes for works on the converter station. Nemo Link included these Siemens variation costs within its PCR capex submission; Ofgem reviewed those variation claims as part of its assessment of construction and reprogramming costs. The document did not provide a separate award date for the Siemens contract beyond references within the PCR submission.
