Siemens Gamesa: giant wind turbine breakthroughs?

Siemens Gamesa is a leader in offshore wind, listed in Spain, with a €34bn order book and 26k employees (in 2021). It is pushing the boundaries of offshore wind, launching a 14MW turbine in 2020, with a 222-meter rotor diameter.

This data-file scores 50 of the company’s recent patents from 2020-21, using our usual framework. Many of the innovations were specific, intelligible improvements. We would loosely estimate that half of these are aimed at resolving challenges being incurred with the up-scaling of turbines.

The data-file will be helpful if you are looking for specific details into Siemens Gamesa’s innovations and the focus areas in its patents. Which are broad-ranging.

Our main debate is whether these innovations are truly deflationary, as many of them seem to add complexity, including in blade design, operational  monitoring, transportation issues and electrical smoothing.
