Wind power has emerged as an important source of renewable energy in the last decade. As Global Wind Energy Council reported, 2023 was a record-breaking year for the wind energy sector, with 117 GW of new wind power installed worldwide. This 50% increase in wind power installation from the previous year is the result of combined efforts by various stakeholders, including wind farm construction companies.

The successful construction and operation of these wind farms require expertise, advanced technology, and a commitment to innovation. The wind farm construction companies around the world provide comprehensive solutions to the greener future ahead.

In this blog we explore the top 7 wind farm construction companies in the world according to Blackridge Research’s offshore wind database. Also we’ll understand the crucial role of each wind farm developer in transforming the global energy mix.
