Offshore substations (OSS) are the single most schedule-critical procurement decision in offshore wind. Yet, commissioning timelines vary significantly depending on transmission type and who is procuring the platform.
Aegir Insights' OSS Order Book tracks this dynamic across 150+ orders globally – a stark difference that emerges from the data is the lead time difference in TSO-lead vs. developer-lead OSS contracts.
🔹 Developer-led orders run at an average delivery lead time of 3-5 years; diving into transmission types, unveils that developer-led HVAC orders represent the lower end of the band with 3 years from award to commissioning and HVDC orders sit at 4-5 years.
🔹 TSO-led HVDC orders have hit a new high of 6 to 8 years.
🔹 OSS manufacturing and construction backlogs can become a leading indicator for offshore wind delivery risk. With over 40 firm orders currently active across Europe, manufacturing and integration capacity is running at or near its limit and projects still awaiting OSS award carry scheduling risks.
Clients can explore this and much more in Aegir Insights’ Offshore Substations Order Book, mapping out orders on OSS, including:
🔹 High-voltage alternate current (HVAC) and high-voltage direct current (HVDC) platforms installed and ordered,
