The rapid growth expected for global wind energy installations
over the coming decade and increasing wind turbine sizes will
result in wind industry steel consumption doubling this decade.
Steel prices have more than doubled in some regions between 2020
and 2021 on account of severe supply chain disruptions,
highlighting the potential risk to the wind industry due to the
commodity's price volatility.
Our team takes a closer look at the demand for steel by the wind
industry, current pricing challenges and the normalization
timeframe, potential steel price impacts on wind capital costs and
levelized cost of electricity, and future challenges related to
steel in for the wind industry.
The global wind industries steel consumption is expected to
double this decade reaching 147 MMT between 2021-2030, driven by
forecast global additions of 960 GW. Steel is critical for both
onshore and offshore wind turbines, making up 20% and 90% of
turbine mass for onshore and offshore wind, respectively. Both
onshore and offshore turbine towers are fabricated from steel, and
while onshore wind turbines rely on concrete for their foundations,
offshore wind turbines rely on steel structures such as monopiles
and jackets for their foundations.

technology, 2020-30
This is important considering average global steel prices almost
doubled between 2020 and 2021, reducing wind OEM profit margins and
increasing wind project costs, highlighting the risk of steel price
volatility causing disruption along the wind industry value
chain.
Figure 2: Steel price overview
The recent steel price spikes alone could lead to increasing
wind project CAPEX and LCOE of 6% and 4.5%, respectively. Onshore
wind project CAPEX is most significantly impacted by increasing
steel price due to having overall lower project costs compared to
offshore wind. Future steel related challenges exist for the wind
industry due to increasing implementation of carbon pricing
mechanisms, steel industry decarbonization costs along with
component fabrications and transport difficulties.
